Dinamik Bir Yazılımın Çemberin Analitik İncelenmesinde Başarıya Etkisi ve Matematik Öğretmeni Adaylarının Görüşleri

The aim of the study was to examine the effects of geometry instruction, which was performed with a dynamic software, on the success of prospective elementary mathematics teachers in the analytical analysis of the circle, and to reveal their opinions in this performed geometry instruction. The embedded research design, which is among the mixed research approaches, was used in the study. The research applied 29 prospective elementary mathematics teachers and the data obtained from circle success test and semi-structured focus group interview form. In view of the analysis of the data, it was observed that the instruction, which was performed with a dynamic software, provided a positive contribution to the success of prospective teachers in the subject of the analytical analysis of the circle. Moreover, it was observed that the prospective teachers expressed that geometry instruction in a dynamic environment enabled them to understand point of power and the points on the circle, and it had positive effects on developing thinking skills, visuality, retention, learning in a short time, concretization and focusing the attention of the students with dynamism. In contrast, it was determined that the use of technology was low in mathematics and geometry courses in the secondary education institutions, and prospective teachers wanted to perform geometry instruction in dynamic environments in their teaching profession.

Using dynamic software in mathematics: the case of reflection symmetry

This study was carried out to examine the effects of computer-assisted instruction (CAI) using dynamic software on the achievement of students in mathematics in the topic of reflection symmetry. The study also aimed to ascertain the pre-service mathematics teachers’ opinions on the use of CAI in mathematics lessons. In the study, a mixed research method was used. The study group of this research consists of 30 pre-service mathematics teachers. The data collection tools used include a reflection knowledge test, a survey and observations. Based on the analysis of the data obtained from the study, the use of CAI had a positive effect on achievement in the topic of reflection symmetry of the pre-service mathematics teachers. The pre-service mathematics teachers were found to largely consider that a mathematics education which is carried out utilizing CAI will be more beneficial in terms of ‘visualization’, ‘saving of time’ and ‘increasing interest/attention in the lesson’. In addition, it was found that the vast majority of them considered using computers in their teaching on the condition that the learning environment in which they would be operating has the appropriate technological equipment.
