Özet:

–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
