The application of the capabilities of information technology in the process of teaching mathematics by computer technology teachers has brought with it many advantages. The use of technology in schools is effective in terms of improving students' cognitive skills. When we look at the areas of use of new pedagogical technologies, they provide innovative learning with different educational materials in many teaching areas, especially mathematics education. Observations show that in most cases, the teacher works alone during the lesson, and the students remain observers. For teachers, it is desirable to improve the effectiveness of the use of technology in mathematics lessons, its structure and content and to determine the effectiveness of ‘Information Technologies in Mathematics Education’. This case study aims to investigate the impact of the integration of information and communication technology applications on mathematics education. Within the scope of this general purpose, semi-structured interview questions prepared by the researchers were asked. A qualitative method was used in the research. The opinions of 32 mathematics teachers who use technology in their high school courses were consulted. As a result of the research, it was concluded that technology-supported training is very effective in mathematics. It has been concluded that the use of a numerical field of mathematics and technology-supported applications is effective in developing skills in students. In the same way, it has emerged that mathematics teachers need in-service training about technology-supported trainings.
