Education is one of the main factors that provide social development and change in the desired direction. With this awareness, many parents take various courses that they think will benefit to their children. National and international reports show that Turkish students' mathematics achievement is very low. Our century requires understanding mathematics and being able to use it in daily life and business life. The aim of this study is to evaluate the 8th grade mathematics course applied in support and training courses (STC) in line with the opinions of students and parents. The research was designed in the multiple-case design of qualitative research. The study group of the research consists of 19 eighth grade students from 3 different public schools and 12 eighth grade student parents in the 2018-2019 academic year. Semi-structured interview method, one of the interview methods, was used in the study. The data were analyzed by creating themes, categories and codes using content analysis method. When the findings obtained as a result of the study were examined, it was found that 8th grade students found the mathematics lesson hours of the STC too many and the teachers gave excessive homework. Students stated that this situation caused them fatigue and low performance. In addition, it was stated that teachers generally used the method of direct instruction, question banks and acquisition tests as materials. According to the students, the fact that the lessons are not fun and not supported by sports activities decreases their participation in the courses. According to parents, teachers cannot seriously follow student development in courses and cannot provide class discipline. Parents stated that if this situation persists, they would stop taking additional lessons for their children.
