This paper presents apps designed to assist students in understanding and developing proofs in geometric theorems. These technologies focus on triangle congruence, triangle similarity and properties of parallelograms. Focus group discussions and initial testing of the apps revealed that the apps offered a more engaging medium for learning proving…

A geometrical task is presented with multiple solutions using different methods, in order to show the connection between various branches of mathematics and to highlight the importance of providing the students with an extensive 'mathematical toolbox'. Investigation of the property that appears in the task was carried out using a computerized tool.

This case study investigates the impact of the integration of information and communications technology (ICT) in mathematics visualization skills and initial teacher education programmes. It reports on the influence GeoGebra dynamic software use has on promoting mathematical learning at secondary school and on its impact on teachers' conceptions…

This paper reports findings of an explorative study that examine the effectiveness of a GeoGebra-based dynamic applet in supporting students' construction of the formal definition of the limit of a sequence or convergence. More specifically, it is about how the use of the applet enables students to make connections between the graphical…

This paper explores how a young child (56 m) builds an understanding of the cardinality principle through communicative, touchscreen-based activities involving talk, gesture and body engagement working via multimodal, touchscreen interface using contemporary mobile technology. Drawing upon Nemirovsky's perceptuomotor integration theoretical lens…

An important and interesting area in the study of triangle geometry is the related issue of extrema problems and inequalities. These problems play a significant role in the mathematics study program in high school. In tasks such as these, the difficulty level is high when one does not know in advance what the expected answer is. When one knows…

This paper presents our experience of integrating technological tools into our mathematics teaching (in both disciplinary and didactic courses) for student-teachers. In the first cycle of our study, a variety of technological tools were used (e.g., dynamic software, hypertexts, video and applets) in teaching two disciplinary mathematics courses.…

The use of stored programs for solving statistical problems was introduced into a statistics course. Contrary to expectation the students did not enjoy the course more. They did become more aware of the importance of statistics, however. (SD)

The present mode of computer usage, with its emphasis on numerical problem solving, in typical undergraduate mathematics courses is questioned. The role of the computer in developing an awareness of shape and pattern is emphasized. (DT)

The author argues that programs to prepare the casual computer user are needed. Too much emphasis has been placed on thorough understanding of the working of the machine, and not enough on general principles of man-machine interaction. (SD)

This article discusses the pros and cons of CAI (computer assisted instruction) as compared to "computer as laboratory" (simulation, modelling, problem-solving, calculation, data bases). (DT)

The role of computer science in relation to education is discussed from two points of view: (1) the use of computer models for studying the learning process, and (2) the use of the computer as a teaching device. (SD)
