Abstract: This chapter focuses on digital technologies and geometry education, a combination of topics that provides a suitable avenue for analysing closely the issues and challenges involved in designing digital technologies for learning mathematics, while, at the same time, recognising that the use of such technologies can and does shape the mathematical activity of the user. In revealing these issues and challenges, the chapter examines the design of digital technologies and appropriate forms of learning activities for a range of geometries, including Euclidian 3D and co-ordinate geometry and non-Euclidean geometries such as spherical, hyperbolic and fractal geometry. This analysis reveals the decisions that designers take when designing for different geometries on the flat computer screen. Such decisions are not only about the geometry but also about the learner in terms of supporting their perceptions of what are the key features of geometry.

Abstract: This chapter focuses on the linking of geometry and algebra in the teaching and learning of mathematics - and how, through such linking, the mathematics curriculum might be strengthened. Through reviewing the case of the school mathematics curriculum in England, together with examples of how the power of geometry can bring contemporary mathematics to life in the classroom, the chapter argues for greater concinnity in the mathematics curriculum, especially in terms of the harmonious/purposeful reinforcement of mathematical thinking through the linking of geometry and algebra.

Abstract: In this paper we report on our analysis of textbooks commonly used for teaching students about proof in geometry in lower secondary school in Japan. From our analysis we found that, as expected from the curriculum specification, deductive reasoning is prominent in Japanese textbooks. Yet the way that proof and proving is presented in these textbooks shows geometry as a very formal subject for study, one that omits to illustrate convincingly for students the difference between formal proof and experimental verification. As such, we argue that an improvement in textbook design is likely to involve providing students with more effective instructional activities so that they appreciate more fully the notion of ‘generality of proof’.

Abstract: In our work we focus on learning from the teaching of proof in geometry at the lower secondary school level across countries in the East and in the West. In this paper we summarize selected findings from a series of classroom-based experiments carried out over an extended period of time. By extracting key findings from our research, we show how we are identifying good models of pedagogy and using these to develop new pedagogic principles that are intended to help secondary school students not only to know ‘how to proceed’ with deductive proof, but also to understand more fully why such formal proof is necessary to verify mathematical statements.

Abstract: Students at Key Stage 3 (ie aged 11-14) in English schools are expected to learn the definitions of the properties of triangles, quadrilaterals and other polygons and to be able to use these definitions to solve problems (including being able to explain and justify their solutions). This paper focuses on a pair of Year 8 students (aged 12-13) working on a task using dynamic geometry software. In the research, the children investigated triangles and quadrilaterals by dragging two lines within a shape (ie the diagonals of a quadrilateral, or base and height of a triangle) and noting the position and orientation of the lines which gave rise to specific shapes. Following this, the students were asked to use what they had found in order to construct specific triangles and quadrilaterals when starting with a blank screen. While the research is currently ongoing, and is using a design research methodology, the evidence to date is that the task has the potential to scaffold students’ thinking around the properties of 2D shapes and hence support the development of geometric reasoning.

Abstract: During the primary school years, children are typically expected to develop ways of explaining their mathematical reasoning. This paper reports on ideas developed during an analysis of data from a project which involved young children (aged 5-7 years old) in a whole-class situation using dynamic geometry software (specifically Sketchpad). The focus is a classroom episode in which the children try to decide whether two lines that they know continue (but cannot see all of the continuation) will intersect, or not. The analysis illustrates how the children can move from an empirical, visual description of spatial relations to a more theoretical, abstract one. The arguments used by the children during the lesson transcend empirical arguments, providing evidence of how young children can be capable of engaging in aspects of deductive argumentation.

Abstract: The embedding of technology into mathematics teaching is known to be a complex process. GeoGebra, an open-source dynamic mathematics software that incorporates geometry and algebra into a single package, is proving popular with teachers - yet solely having access to such technology can be insufficient for the successful integration of technology into teaching. This paper reports on aspects of an NCETM-funded project that involved nine experienced teachers collaborating in developing ways of providing professional development and support for other teachers across England in the use of GeoGebra in teaching mathematics. The participating teachers tried various approaches to better integrate the use of GeoGebra into the mathematics curriculum (especially in geometry) and they designed and led professional development workshops for other teachers. As a result, the project initiated a core group which has started to be a source of support and professional development for other UK teachers of mathematics in the use of GeoGebra.

Abstract: Research across many countries reports that teaching the key ideas of proof and proving to all students is not an easy task. This paper reports on the session of the BSRLM Geometry Working Group which examined current classroom material from the UK with the intention of uncovering the ‘opportunities for proof’ in geometry that are provided by such material. To carry out such an analysis three analytical frameworks are compared. Two of the analytical frameworks, while placing proof and proving in a wider context of learners’ mathematics, may not fully uncover the detail of proof and proving. The third analytical framework, while permitting a detailed analysis of explicit proof and proving, may not fully account for textbooks that devote most space to discussions of proof and proving and/or contain problems that implicitly provoke proof. This comparison reveals some of the complexity of textbook analysis and suggests that further work is needed on a suitable analytical framework.

Abstract: This paper examines a key period of change in geometry teaching in England. Our focus is the character and nature of the recommendations of the geometry report of the UK Mathematical Association in 1902. We analyse historical documents of the Mathematical Association using a theoretical framework developed from Cooper’s model. Our analysis shows that the character and recommendations of the Mathematical Association report was influenced by various factors including: that the Mathematical Association members still respected the traditional Euclidean approach to geometry as a basis for school geometry; that the academic and power resources available to the Mathematical Association at the time were not sufficient for a complete change from the traditional approach; that conflicts between the various members of the Mathematical Association prevented a complete consensus; and that the climate outside the teaching committee of the Mathematical Association was not ready for radical reform at that time.

Abstract: Spatial visualization is an important skill that deserves further instructional attention. One way to improve students’ spatial visualization and reasoning abilities is to provide learning activities that exploit the possibilities of exploring the properties of 3D objects in appropriately developed dynamic and interactive computer applications. The material presented in this book relates to software applications developed as the main outcome of the EU-funded project entitled DALEST: Developing an Active Learning Environment for Stereometry. The book provides some background information on the project, an overview of the functions of the software developed within the framework of this project, plus some classroom activities for use with the software.

Abstract: An issue for many students studying mathematics in upper secondary education or college, as international research demonstrates, is comprehending the concepts of Calculus/Analysis. In attempting to improve teaching, the combination of the dynamic nature of the concepts of Calculus/Analysis and its historic roots in geometry, leads to the suggestion that teaching may be aided by the use of dynamic geometry software. The material presented in this book is one outcome of the EU-funded project entitled CalGeo: Teaching Calculus/Analysis with the use of dynamic geometry tools. The didactic activities presented in the book are informed by the CalGeo framework and address the introduction of concepts and the teaching of Calculus/Analysis theorems with the use of dynamic geometry software. Each activity offered in the book consists of one or more worksheets for students, accompanied by guidance for the teacher.

Abstract: This paper discusses ways of enhancing the teaching of mathematics through enabling learners to gain stronger links between geometry and algebra. The vehicle for this is consideration of the affordances of GeoGebra, a form of freely-available open-source software that provides a versatile tool for visualising mathematical ideas from elementary through to university level. Following exemplification of teaching ideas using GeoGebra for secondary school mathematics, the paper considers current emphases on geometry and algebra in the school curriculum and the current (and potential) impact of technology (such as GeoGebra). The paper concludes by raising the implications of technological developments such as GeoGebra for the pre-service education and inservice professional development of teachers of mathematics.

Abstract: While, commonly across the world, selected key ideas of the Calculus are introduced to students in the final years of schooling, and are thence built upon as students take a full course in Analysis at University, there remains much to learn about how best to introduce such ideas and how to develop and expand the ideas at University level. This paper reports on the work of a European-funded project involving four countries in which the potential of dynamic software was exploited in the teaching of topics such as infinite processes, limits, continuity, differentiation and integration. Amongst the approaches adopted in the project, problem-solving situations were developed through which students, while their knowledge may initially be inadequate, could approach intuitively the central mathematical notion in ways that are consistent with formal mathematical definitions. Amongst the implications of the project, in terms of the debate about what is suitable preparation for students embarking on a course of analysis at University level, are that it might be useful to think in terms of two categories of learning activity – the first is introducing student to relevant concepts and the second focuses on the teaching of theorems. These two categories entail a different design of learning activity.

Abstract: Defining and classifying quadrilaterals, though an established component of the school mathematics curriculum, appears to be a difficult topic for many learners. The reasons for such difficulties relate to the complexities in learning to analyse the attributes of different quadrilaterals and to distinguish between critical and non-critical aspects. Such learning, if it is to be effective, requires logical deduction, together with suitable interactions between concepts and images. This paper reports on an analysis of data from a total of 263 learners. The main purpose of the paper is to present a theoretical framing that is intended to inform further studies of this important topic within mathematics education research. This theoretical framing relates prototype phenomenon and implicit models to common cognitive paths in the understanding of the relationship between quadrilaterals.

Abstract: The data reported in this paper come from a study aimed at explaining how successful teachers teach proof in geometry. Through a careful analysis of a series of lessons taught in Grade 8 in Shanghai, China, the paper reports on the appropriateness of the van Hiele model of ‘teaching phases’ within the Chinese context. The analysis indicates that though the second and third van Hiele teaching phases could be identified in the Chinese lessons, the instructional complexity of, for example, the guided orientation phase means that more research is needed into the validity of the van Hiele model of teaching.

Abstract: This paper reports on the design of a library of software applications for the teaching and learning of spatial geometry and visual thinking. The core objective of these applications is the development of a set of dynamic microworlds, which enables (i) students to construct, observe and manipulate configurations in space, (ii) students to study different solids and relates them to their corresponding nets, and (iii) students to promote their visualization skills through the process of constructing dynamic visual images. During the developmental process of software applications the key elements of spatial ability and visualization (mental images, external representations, processes, and abilities of visualization) are carefully taken into consideration.

Abstract: This paper reports on the theoretical perspectives underpinning the design of a 3D geometry software environment called 3DMath. The idea of 3DMath is to develop a dynamic three-dimensional geometry microworld, which enables students to construct, observe and manipulate geometrical figures in 3D space, and to focus on modelling geometric situations, and enable teachers to help students construct their understanding of stereometry. During the developmental of 3DMath, the key elements of visualization (mental images, external representations, and the processes and abilities of visualization) were carefully taken into consideration. The aim of this paper is to illustrate how the design of the 3DMath software was informed by these key elements of visualization, as well as by theories related to the philosophical basis of mathematical knowledge and to semiotics. Thus, the paper describes how the features of the software are designed to enhance the elements of visualization, and to satisfy the characteristics of instructional techniques that are appropriate to these theoretical perspectives.

Abstract: The main aim of this study is to investigate geometry teaching at the lower secondary school level in Shanghai, with particular attention to the relationship of the teaching/learning phases organized by teachers with students’ thinking levels demonstrated in classrooms and examination papers at Grade 8 (students age 14). Analysis of data from the pilot study suggests that an essential teaching strategy used by the Chinese teachers was mutually reinforcing visual and deductive approaches in order to develop students’ geometric intuition in the learning of deductive geometry.

Abstract: Whilst teachers’ mathematics knowledge is known to play a significant role in shaping the quality of their teaching, much less is known about the nature and extent of that knowledge, how it develops, and how such development can be supported through initial teacher training and continuing professional development. Earlier research has indicated that pre-service (trainee) primary teachers’ subject knowledge of geometry is amongst their weakest knowledge of mathematics. This paper reports on an analysis of geometry subject knowledge data gathered in Scotland from undergraduate pre-service primary teachers, focusing on their ability to define and classify quadrilaterals. The results indicate that many trainee primary teachers have relatively poor command of these aspects of mathematics.

Abstract: An authoritative report into the teaching and learning of geometry argued, amongst other things, that the most significant contribution to improvements in geometry teaching are to be made by the development of good models of pedagogy, supported by carefully designed activities and resources. This meeting of the BSRLM Geometry Working Group provided an opportunity to consider approaches to the teaching of geometry developed in China and Japan and to review what research might have to contribute to developing new pedagogic approaches.

Abstract: Considerable research has indicated that amongst the factors which make the most significant contribution to high student achievement in mathematics is secure subject knowledge on the part of the teacher as this underpins an approach to mathematics in which topics are seen as part of a coherent set of related ideas, with clear progression and links to previous and future learning. This paper reports part of the findings from a study of trainee teachers’ knowledge of basic geometrical figures, in particular focusing on what knowledge they have of parallelograms and how they use this knowledge to solve geometrical problems. The findings indicate that only a minority of trainee primary teacher have a fully sophisticated knowledge of parallelograms and of how to use the properties of parallelograms to solve relevant problems.

Abstract: This paper reports on a study of geometry teaching at the lower secondary school level in Shanghai, China. Through an analysis of data from observing a variety of Year 9 (Grade 8) lessons, and utilising data from the students' performance in school examinations, the study suggests that teachers in this region of China use classroom strategies that attempt to reinforce visual and deductive approaches in order to develop students' thinking in the transition to deductive geometry education.

Abstract: GeoGebra is a software package and is so named because it combines geometry and algebra as equal mathematical partners in its representations. At one level, GeoGebra can be as a dynamic geometry system like other, commercially available, software. But this is only part of the story. Another window (the algebra part of GeoGebra) provides an insight into the relationship between the geometric aspects of figures and their algebraic representations. Here each equation or set of coordinates can be edited in the algebra window and the figure instantly changes. What is more, an equation (or a function) can be typed into the space at the foot of the GeoGebra interface and the corresponding geometric representation will appear in the geometry window. Perhaps utilising GeoGebra could inspire a change from regular forms of enrichment/ extension activity to things that need high level thinking, and things that pupils may find themselves wanting to follow-up outside school lessons.

Abstract: This short user-review summarise the research that has investigated the use of dynamic geometry software (DGS) in the teaching and learning of mathematics. Overall, the research has found that DGS cannot provide a self-contained environment and that the software itself does not necessarily mean that students will learn geometry theory. Research also suggests that it can take quite a long time for the benefits of using DGS to emerge but that this investment is worthwhile in developing students' knowledge of geometry. The sorts of tasks that students tackle, the form of teacher input and the general classroom atmosphere are all important factors.

Abstract: The focus of this paper is a software genre usually referred to as 'dynamic geometry' because of the ability of the user to dynamically manipulate geometrical figures created with the software tool. Using data from a longitudinal study of 12-13 students' use of dynamic geometry software, the focus of the analysis is on the interpretations the students make of geometrical objects and relationships when using this form of software. The analysis suggests that the students' mathematical reasoning is shaped by their interactions with the software in that their ability to explain geometrical facts and relationships evolves from imprecise, 'everyday' expressions, through reasoning that is overtly mediated by the software environment, to mathematical explanations of the geometric situation that transcend the particular tool being used. Such findings suggest that curriculum initiatives that encourage the use of dynamic geometry software are appropriate but that the incorporation of such software into classroom practices is unlikely to be straightforward.

Abstract: International comparative research in mathematics education has found, perhaps unsurprisingly, that teachers are a key influence on pupil learning. Given that the development of pupils’ capability in geometrical reasoning continues to be an issue of considerable international concern, this paper reports an analysis of lower secondary school lesson suggestions offered by expert teachers from China and Japan (countries selected because they represent some interesting similarities and contrasts). The analysis indicates some striking similarities between suggested lessons, but some noteworthy differences. Both these may be related to the educational context in which the lesson suggestions are presented.

Abstract: This review suggests that students working with Logo, by creating and interacting with objects that are visible, quantifiable, and adhere to conventional mathematics, build connections between spatial and numeric/algebraic thinking. Using Logo can help students make mathematics more concrete, while simultaneously supporting algebraic formalisation of actions as Logo 'procedures'. Working with Logo affords students opportunities to try out ideas and modify plans, elements that are key to mathematical problem solving. Students can make and test conjectures, a vital component of mathematical reasoning.

Abstract: Achievement in mathematics continues to be a crucial factor in the success of school systems around the world. As a result, this area of the curriculum has been the subject of considerable international comparative research, mostly focussed on pupil achievement but also examining teaching methods, curricula, and so on. In all this, and perhaps unsurprisingly, the central role of teachers, and how they structure their lessons, has emerged as a key factor in pupil learning. A number of projects have examined the structure of mathematics lessons, either to typify individual lessons in specified countries, or as an attempt to describe the variety of lesson structures used by particular teachers in particular countries over a sequence of lessons. To date there has been little comparative work specifically on how teachers structure mathematics lessons to develop geometrical reasoning despite the issue of how to improve geometry teaching being of considerable international concern. This paper reports early data from a larger comparative study that includes the analysis of classroom teaching materials. This paper compares suggestions about how teachers might structure geometry lessons in lower secondary school in three countries, China, Japan, and the UK (specifically England), chosen because they represent some interesting similarities and contrasts. The analysis focuses on the background to the suggestions available to teachers, in particular where approaches are similar and where they diverge. What the implications might be for student achievement in geometry in the three countries is identified as an area for future research.

Abstract: Following a period of declining emphasis, especially in Western countries, geometry is re-emerging as a key component of the mathematics education at school level. As a result, the ways in which teachers might develop their students' geometrical reasoning is the subject of considerable international debate. Yet despite international comparative studies, such as TIMSS, there has been little comparative work specifically on how mathematics teachers structure lessons to develop geometrical reasoning. This paper identifies key questions about the structure of lessons that are intended to develop geometrical reasoning and proposes an approach to examining such lessons in lower secondary schools in China

Abstract: Intuition is often regarded as essential in the learning of geometry, but how such skills might be effectively developed in students remains an open question. This paper reviews the role and importance of geometrical intuition and suggests it involves the skills to create and manipulate geometrical figures in the mind, to see geometrical properties, to relate images to concepts and theorems in geometry, and decide where and how to start when solving problems in geometry. Based on these theoretical considerations, we illustrate a range of student tasks that we argue should contribute to developing students' geometrical intuition.

Abstract: Intuition is often regarded as essential in the learning of geometry, but questions remain about how we might effectively develop students' such skills. This paper provides some results from analyses of innovative geometry teaching in the early part of the 20th century, a time when significant efforts were being made to improve the teaching and learning of geometry. As examples, we examine the tasks for students that can be found in Treutlein's "Geometrical Intuitive Instruction" (Germany) and Godfrey's geometry textbook (England). The analyses suggest that educators at that time attempted to develop students' intuitive skills through various practical tasks such as drawing, measurement, and imagining and manipulating figures, which could be useful for current geometry teaching. We also identify different approaches taken to the development mathematics teaching in Germany and England.

Abstract: This report to the QCA details the work of a group of mathematicians, mathematics educators, local authority officers, and teachers on developing teaching ideas that focus on the development of geometrical reasoning at the secondary school level. The study suggests that it is appropriate for all teachers to aim to develop the geometrical reasoning of all pupils, but equally that this is a non-trivial task. Obstacles that need to be overcome are likely to include uncertainty about the nature of mathematical reasoning and about what is expected to be taught in this area among many teachers, lack of exemplars of good practice (although this report attempts to address this by providing a range of lesson descriptions), especially in using transformational arguments, lack of time and freedom in the curriculum to properly develop work in this area, an assessment system which does not recognise students' oral powers of reasoning, and a lack of appreciation of the value of geometry as a vehicle for broadening the curriculum for high attainers, as well as developing reasoning and communication skills for all students.

Abstract: The dual nature of geometry, in that it is a theoretical domain and an area of practical experience, presents mathematics teachers with opportunities and dilemmas. Opportunities exist to link theory with the everyday knowledge of pupils but the dilemmas are that learners very often find the dual nature of geometry a chasm that is very difficult to bridge. With research continuing to focus on understanding the nature of this problem, with a view to developing better pedagogical techniques, this paper examines the place of experimental tasks in the process of learning geometry. In particular, the paper provides some results from an analysis of innovative geometry textbooks designed in the early part of the 20th Century, a time when significant efforts were being made to improve the teaching and learning of geometry. The analysis suggests that experimental tasks have a vital role to play and that a potent tool for informing the design of such tasks, so that they build effectively on pupils' geometrical intuition, is the notion of the geometrical eye, a term coined by Charles Godfrey in 1910 as the power of seeing geometrical properties detach themselves from a figure.

Abstract: This paper presents an analysis of how the geometry component of the National Curricula for mathematics in Japan and in one selected country of the UK, specifically Scotland, is interpreted by textbook writers. The analysis indicates that, following the specification of the mathematics curriculum in these countries, Japanese textbooks set out to develop students' deductive reasoning skills through the explicit teaching of proof in geometry, whereas comparative Scottish textbooks tend, at this level, to concentrate on measuring, drawing, finding angles, and so on, coupled with a modicum of opportunities for conjecturing and inductive reasoning. The available research suggests that each approach has its own strengths and weaknesses. Finding ways of capitalising on the strengths and mitigating the weaknesses could prove helpful in formulating new curricular models and designing new student textbooks. An emerging issue is how the design of textbooks might either build on, or neglect, students' intuitive skills when they tackle geometrical problems.

Abstract: Developing a good model of the school geometry curriculum continues to be one of the most important tasks in curricular design in mathematics. This paper reports an initial analysis of current best-selling textbooks for lower secondary schools in Japan and the UK (specifically Scotland) using an analytic framework derived from the study of the textbooks in the "Trends in International Mathematics and Science Study" (TIMSS). Our analysis indicates that, following the specification of the mathematics curriculum in these countries, Japanese textbooks set out to develop students' deductive reasoning skills through the explicit teaching of proof in geometry, whereas comparative UK textbooks tend, at this level, to concentrate on finding angles, measurement, drawing, and so on, coupled with a modicum of opportunities for conjecturing and inductive reasoning. The available research suggests that each approach has its own strengths and weaknesses. Finding ways of capitalising on the strengths and mitigating the weaknesses could prove helpful in formulating new curricular models and designing new student textbooks.

Abstract: This short user-review summarise the research that has investigated the use of dynamic geometry software (DGS) in the teaching and learning of mathematics. Overall, the research has found that DGS cannot provide a self-contained environment and that the software itself does not necessarily mean that students will learn geometry theory. Research also suggests that it can take quite a long time for the benefits of using DGS to emerge but that this investment is worthwhile in developing students' knowledge of geometry. The sorts of tasks that students tackle, the form of teacher input and the general classroom atmosphere are all important factors.

Abstract: This chapter examines the structure and recommendations of the UK National Numeracy Strategy (NNS) with respect to the teaching of geometry at primary school. It looks at ways in which the NNS recommendations might be best taken forward and whether there are important aspects of geometry that the Strategy has omitted or to which it has paid too little attention. It suggests that, until spatial and visual thinking is given greater status within the mental and oral segments of primary mathematics lessons, and until more curriculum space at primary level is devoted to geometry, children may well continue to have insufficient opportunity to develop fundamental visualisation and spatial reasoning skills that are so important in an increasingly visual world.

Abstract: This chapter analyses a range of key issues in the teaching and learning of geometry. These include the nature of geometry, why geometry is important in the curriculum at school level and beyond, what geometry can be included at the school level, the aims of teaching geometry, and how geometry can be best taught and learnt. The chapter addresses the use of information and communication technology in geometry education and concludes that the twenty-first century is one where spatial thinking and visualisation are vital areas for education. The chapter includes a number of tasks related to the issues addressed and an appendix giving details of resources.

Abstract: Deciding how to teach geometry remains a demanding task with one of major arguments being about how to combine the intuitive and deductive aspects of geometry into an effective teaching design. In order to try to obtain an insight into tackling this issue, this paper reports an analysis of innovative geometry textbooks which were published in the early part of the 20th Century, a time when significant efforts were being made to improve the teaching and learning of geometry. The analysis suggests that the notion of the geometrical eye, the ability to see geometrical properties detach themselves from a figure, might be a potent tool for building effectively on geometrical intuition so as to provide a bridge into deductive geometry.

Abstract: One outcome of the implementation of the (UK) National Numeracy Strategy at the primary school level is the privileging of the teaching and learning of number. Yet, as the recent Royal Society report on geometry stresses, it is important to begin the developing of spatial thinking and reasoning at this level. This report reviews what trainee primary teachers might need to know about geometry in order to teach the geometry component of the mathematics curriculum effectively and confidently. Some initial findings are given from research which suggests that, in the UK, geometry is the area of mathematics in which trainees perform most poorly in initial baseline tests and have the least confidence to teach. Hence it is the area in which trainees need to make most progress if they are to gain qualified teacher status.

Overall, the research has found that DGS cannot provide a self-contained environment and that the software itself does not necessarily mean that students will learn geometry theory. Research also suggests that it can take quite a long time for the benefits of using DGS to emerge but that this investment is worthwhile in developing students' knowledge of geometry.

Abstract: The provision of mathematics curriculum that encourages students to develop their powers of spatial thinking and visualisation, as important components of their geometrical reasoning, is seen as a key area for development in mathematics education. This short article reviews the nature of spatial thinking and visualisation, both in mathematics education more generally and in geometry in particular, illustrating how both forms of thinking are vital to mathematics.

Abstract: Dynamic geometry software promises direct manipulation of geometrical objects and relations. This paper reports aspects of a research study deigned to examine the impact of using such software on student conceptions. Analysis of the data from the study indicates that, while the use of dynamic geometry software can assist students in making progress towards more mathematical explanation (and thereby provide a foundation on which to build further notions of deductive reasoning in mathematics), the 'dynamic' nature of the software influences the form of explanation, especially in the early stages.

Abstract: The (UK) National Numeracy Strategy includes the term 'oblong' in the framework for teaching mathematics to pupils aged 8 and over. This article takes issue with this specification. It argues that the term "oblong" is not mathematical and that its use in mathematics lessons both makes it more difficult for pupils to appreciate that squares are rectangles and undermines the key idea of understanding generalisation in mathematics (when "weaker" concepts are used to generalise towards 'stronger' concepts rather than exclude them).

Abstract: Major improvements in the teaching and learning of geometry will only come, argues a recent report from the Royal Society and Joint Mathematical Council, through the development of a completely new pedagogy for geometry. This report examines existing models of pedagogy for geometry and considers what research might have to contribute to the development of new approaches. New pedagogic approaches for geometry need to give greater emphasis to work in 3-D, incorporate the effective use of computer technology, especially dynamic geometry, and focus on discursive methods of engagement and methods of assessment so that the pressure on pupils is not solely to rote learn.

Abstract: Is Euclidean geometry the most suitable part of the school mathematics curriculum to act as a context for work on mathematical proof? This paper examines some of the issues regarding the teaching and learning of proof and proving specifically in relation to Euclidean geometry. Evidence is reviewed which suggests that giving mathematical explanation a higher profile in the classroom should help teachers connect with students' reasoning and guard against the students experiencing learning to prove as no more than a ritual determined by the teacher.

Abstract: The question of how to construct an appropriate geometry curriculum is a long-standing one. A recent estimate suggests that there are more than 50 geometries. This creates a fundamental problem in devising a geometry curriculum: there are just too many interesting things to include so some decision has to be made as to what to include and what to exclude. This report features three perspectives on the issue of the design of the school geometry curriculum.

Abstract: A key issue for mathematics education is how children can be supported in shifting from "because it looks right" or "because it works in these cases" to convincing arguments which work in general. In geometry, forms of software usually known as dynamic geometry environments may be useful as they can enable students to interact with geometrical theory. Yet the meanings that students gain of deductive reasoning through experience with such software is likely to be shaped, not only by the tasks they tackle and their interactions with their teacher and with other students, but also by features of the software environment. In order to try to illuminate this latter phenomenon, and to determine the longer-term influence of using such software, this paper reports on data from a longitudinal study of 12-year-old students' interpretations of geometrical objects and relationships when using dynamic geometry software. The focus of the paper is the progressive mathematisation of the student's sense of the software, examining their interpretations and using the explanations that students give of the geometrical properties of various quadrilaterals that they construct as one indicator of this. The research suggests that the students' explanations can evolve from imprecise, "everyday" expressions, through reasoning that is overtly mediated by the software environment, to mathematical explanations of the geometric situation that transcend the particular tool being used. This latter stage, it is suggested, should help to provide a foundation on which to build further notions of deductive reasoning in mathematics.

Abstract: The fundamental problem in the design of the geometry component of the mathematics curriculum is simply that there is too much interesting geometry, more than can be reasonably included in the mathematics curriculum. The question that taxes curriculum designer is what to include and what to omit. This paper does not seek to resolve the disagreements over the geometry curriculum as, given the nature of the problem, such an endeavour is unlikely to be successful. Rather, the aim is to identifying and review critical issues concerning the design of the geometry curriculum. These issues include the nature of geometry, the aims of geometry teaching, how geometry is learnt, the relative merits of different approaches to geometry, and what aspects of proof and proving to accentuate.

Abstract: Designing the geometry component of the mathematics curriculum is probably the most difficult topic to get right. The fundamental problem is that there is just too much interesting geometry that could be included. This leads to a range of critical issues including just what geometry to include and how to prevent learners experiencing geometry as an incoherent jumble. Also critical are issues of teacher knowledge of geometry.

Abstract: The successful teaching of geometry depends on teachers knowing a good deal of geometry and how to teach it effectively. This report provides a review of what is known about teacher knowledge in geometry, how the knowledge develops and how this knowledge development can be supported by professional development .The available evidence suggests that attention could usefully be paid both to the initial and continuing education of teachers of mathematics in terms of their background and understanding of geometry.

Abstract: It seems that student interpretations of computer-based learning environments may result from the idiosyncrasies of the software design rather than the characteristics of the mathematics. Yet, somewhat paradoxically, it is because the software demands an approach which is novel that its use can throw light on student interpretations. The analysis presented in this paper is offered as a contribution to understanding the relationship between the specific tool being used, in this case the dynamic geometry environment Cabri-Géomètre, and the kind of thinking that may develop as a result of interactions with the tool. Through this analysis a number of effects of the mediational role of this particular computer environment are suggested.

Abstract: A major challenge for mathematics education is to find ways in which proof in geometry has communicatory, exploratory, and explanatory functions alongside those of justification and verification. Ongoing research is suggesting that providing students with tasks which state "prove that...."; might actually inhibit students' capacity for proving. In contrast, open tasks which favour a dynamic exploration of a statement and encourage the use of transformational reasoning may allow students to reconstruct, in terms of properties and relationships, all the elements needed in the proof. In this report we consider the transforming of closed problem into open ones and discuss the use of dynamic geometry software, such as Cabri, in such a process.

Abstract: The use of dynamic geometry software may provide opportunities to improve the teaching and learning of mathematical proof within the context of plane geometry. Yet, it seems, if the approach to proving continues to emphasise a standardised linear deductive presentation, little improvement in student conceptions may result. This paper considers the design of geometrical tasks that could provide the motivation to prove.

Abstract: Recent research suggest that with classroom tasks that combine spatial experiences, mathematising, and communicating, pupils may reveal the nature of their own spatial images and personal language in describing these spatial contexts, and experience the use of formal terminology in making accurate descriptions of their observations and constructions. This report focuses on issues of language use involved in geometry activities when particular emphasis is placed on encouraging pupils' practice of informal and formal mathematical vocabulary.

Abstract: Proof lies at the heart of mathematics yet we know from research in mathematics education that proof is an elusive concept for many mathematics students.  The question that we are now asking is whether the introduction of dynamic geometry systems will improve the situation - or will it make the transition from informal to formal proof in mathematics even harder? How far will innovative teaching approaches with computers assist pupils in developing a conceptual framework for proof and in appropriating proof as a means to illuminate geometrical ideas or will computer use be seen to replace any need for proof?

Abstract: Approaches to the teaching and learning of a chosen topic in geometry can be located somewhere between what are sometimes perceived as two extremes. One such extreme is characterised as "intuitive", the other as "formal" or "axiomatic". There seems to be a number of ways of looking at the relationship between these two positions.

Abstract: This report focuses on some aspects of the nature and role of visualisation and imagery in the teaching and learning of mathematics, particularly as a component in the development of geometrical reasoning. Issues briefly addressed include the relationship between imagery and perception, imagery and memory, the nature of dynamic images, and the interaction between imagery and concept development. The report concludes with a series of questions that may provide a suitable programme for research and lays the foundation for further work of the BSRLM geometry working group.

Abstract: With the growth in interest in geometrical ideas it is important to be clear about the nature of geometrical reasoning and how it develops. This paper provides an overview of three theoretical frameworks for the learning of geometrical reasoning: the van Hiele model of thinking in geometry, Fischbein&'s theory of figural concepts, and Duval's cognitive model of geometrical reasoning. Each of these frameworks provides theoretical resources to support research into the development of geometrical reasoning in students and related aspects of visualisation and construction. This overview concludes that much research about the deep process of the development and the learning of visualisation and reasoning is still needed.

Abstract: In order to understand the learning taking place when students use a dynamic geometry package such as Cabri-Géomètre, a particular focus for study needs to be on the learning mediated through employing such a resource. In this paper I describe how one pair of 12 year old students begin learning how to specify geometrical relationships in Cabri. I argue that, while Cabri provides certain elements of the mathematical language necessary for the articulation of relevant mathematical ideas, significant aspects must be provided by the teacher.

Abstract: The release of a videotape of typical geometry teaching in Japan and the US allows a comparison to be made of the teaching methods typically employed. While the typical US lesson emphasised skill acquisition, the typical Japanese lesson focused on the solving of complex problems through pupil exploration and presentation.

Abstract: The advent of powerful computer graphic packages has coincided with renewed interest in all forms of visual representation in mathematics. As a result, we need to be clear about what we mean by the visual processing necessary to solve mathematical problems involving visual phenomena. Visual processing involves the ability to mentally manipulate and transform visual representations and visual imagery. This paper describes three different elements of the visualisation process: crude visualisation, visualisation as the reading of visual information, and visual processing. Illustrations are given of how the use of a dynamic geometry package such as Cabri-Géomètre both needs and contributes to developing visualisation in all these three senses.

Abstract: The ability to define relationships between objects is one of the most powerful features of a dynamic geometry package such as Cabri-Géomètre. In this paper I document how one pair of 12 year old students begin to come to know about this form of functional dependency within this particular computer environment. I suggest that this process of coming to know about dependency may be understood as an interweaving between the "voices" of the students and the teacher within the socially organised activity taking place in the classroom.

Abstract: The acquiring of formal, abstract mathematical concepts by students may be said to be one of the major goals of mathematics teaching. How are such abstract concepts acquired? How does this formal knowledge interact with the students' intuitive knowledge of mathematics? How does the transition from informal mathematical knowledge to formal mathematical knowledge take place? This paper reports on a research project which is examining the nature of the interaction and possible conflict between the formal and the intuitive components of mathematical activity. Details are presented of an initial study in which mathematics graduates, who could be considered to have acquired formal mathematical concepts, tackled a series of geometrical problems. The study indicates the complex nature of the interaction between formal and intuitive concepts of mathematics. The plans for the next stage in the research project are outlined.

Abstract: With the current and continuing attention on the teaching of number, it is refreshing to welcome this useful publication on geometry from NCET. Its aim is to provide "ideas, suggestions and approaches" to using dynamic geometry software in secondary mathematics based on the experiences of eight teachers from four very different schools who had access to such software over a term or so. In its twenty pages there are a wealth of ideas and practical suggestions in this booklet.

Abstract: Providing a mathematics curriculum that makes proof accessible to school students appears to be difficult. This paper describes work carried out in a secondary school mathematics class in which students worked on tasks designed to enable them to experience the necessity of certain geometrical facts that are true in Euclidean geometry. In these tasks, the students were asked to construct figures using the dynamic geometry package Cabri-Géomètre such that each figure was invariant when any basic object used in the construction was dragged.  It is argued that working on these tasks provided the students with suitable experiences to enable them to explain why these geometrical facts are necessarily true. The changing quality of the students' mathematical analysis suggests that working on suitable tasks with a dynamic geometry package may allow some students to develop an appreciation of proof as explanation.

Abstract: The ICMI study conference on Perspectives on the Teaching of Geometry for the 21st Century took place in Italy in September 1995. This paper reports on the discussion of one of the study working groups which considered geometrical reasoning. Four main themes are covered: visual reasoning, geometrical reasoning in context, the meaning of proving in learning geometry, and assessing the range of reasoning ability in geometry. There was general agreement at the conference that more research is necessary in order to effectively address the wide range of issues that were discussed.

Abstract: This report of a meeting of the BSRLM geometry working group considers what it means to educate someone geometrically and what are useful contexts in which to consider geometry. An undergraduate unit on symmetry is described and this leads to the discussion of context. The relationship between geometry and algebra is briefly mentioned.

Abstract: This article illustrates the ways in which researching the learning of geometrical concepts in the secondary classroom presents both problems and opportunities. The specification of the geometry curriculum, the need to concretise abstract geometrical objects for classroom activities, the role of the teacher, and the need to reconsider geometrical notions from different viewpoints, are all factors which affect the acquisition of geometrical concepts by pupils. These factors can provide problems for the researcher. Yet there are also significant opportunities both to influence policy decisions and to contribute to both theoretical and practical debates regarding the teaching and learning of geometry.
