Data has been collected by applying a questionnaire developed by researchers and consisted of open-ended questions. The questions examine the contribution of Mental Games course to the mathematics education and mathematical skills, evaluation of Mental Games Course Curriculum and the deficiencies of curriculum. According to the findings obtained, teachers have criticized that "Mental" word in Mental Games Course might create negative thoughts and anxiety in students. The majority of teachers shared their views that Mental Games course would make positive contributions on mathematics education in general, and on mathematical skills and the affective characteristics related to mathematics in particular.
