This monograph offers an overview of the current research work carried out in Croatia and the surrounding countries, and specifically an interesting insight in teaching and learning issues in these countries. The authors discuss the need of the general population for becoming good problem-solvers in society of today, which is characterised by…

The purpose of this study was to enhance pre-service secondary mathematics teachers' skills of using the Geometer's Sketchpad (GSP) through Lesson Study. Twenty-four Lesson Study groups each comprising four or five pre-service secondary mathematics teachers who attended a mathematics teaching methods course in a local public university were set up…

Describes features and uses of the Geometry Forum, a National Science Foundation funded Internet project which includes a set of electronic newsgroups for people interested in geometry. (MKR)

In the early stages of working with dynamical geometry environments, students make many more mistakes than if they thought out and implemented the same constructions on paper. Most Czech teachers have very little experience of doing geometry using computers. A methodology which could help them to teach students to avoid mistakes dependent on the…

Discusses the use of a dynamic geometry software package to improve teaching of graph theory in basic graph sketching and in isomorphic, bipartite, and planar graphs. (JRH)

Presents attributes of different types of software including Logo, geometric packages, graphical packages, and spreadsheets, each of which offers different opportunities for learning. Investigates the different ways in which the software allows for performing the given task so as to make the mathematics of the task explicit to users. (KHR)

Focuses on the use of the Internet to deliver resources directly to the secondary school teacher that can be used in the teaching of geometry and which requires a minimum of learning on the teacher's part. Considers the credibility, richness, and value of such resources. (MM)

Focuses on the role of tools provided by a computer microworld (C.AR.ME) on the strategies developed by 14-year-old students for the area measurement of a non-convex polygon. Interprets and classifies student strategies on a transformation and comparison task into categories in terms of the tools used for their development. (Author/MM)

Discusses the distinction between drawing and constructing in dynamic geometry environments. (MKR)

This paper illustrates how to teach parallel perspective using Cabri software. Examples include how to move/present cubes, how to use symmetry to draw a star from triangles, how to modify tessellations, and how to present circles by Cabri software. (Author/KHR)

Describes a method of effectively introducing the concept of radian measure that uses Cabri Geometry II software to construct a circle of arbitrary radius and to measure that radius. The goal is to determine how many of these radii fit around a circle. (DDR)

Discusses software for geometric construction, measurement, and calculation, and software for numerical calculation and symbolic analysis that allows for new approaches to the solution of geometric problems. Illustrates these computer-aided graphical, numerical, and algebraic methods of solution and discusses examples using the appropriate choice…

Identifies a number of algebraic constructs that emerge from conducting investigations in a Logo environment. Details the intellectual struggle of a number of students as they interact with the environment. Reports on the development of a series of comparative case studies with seven students enrolled in an online talent education development…

Students can form beautiful curves through a kinesthetic experience by using a dynamic geometry program. The examples included are parabolas, pursuit curves, spirals, and more. (MM)

Presents an analytic framework to describe and analyze students' answers to proof problems. Employs the framework to investigate ways in which dynamic geometry software can be used to improve students' understanding of the nature of mathematical proof and improve their proof skills. (Author/MM)
