The research has adopted a quasi-experimental design which is based on a group of sixty students, further divided into two groups, one is experimental and the other is control. In order to achieve the objectives of the study, the researcher has designed and applied a number of tools and materials including: a training program based on the “the unit of real functions” in light of TRIZ theory (the instructor manual and the activities), a test to measure creative thinking skills (fluency, flexibility, originality). The research has come to the conclusion that the training program that was based on the principles and strategies of TRIZ theory has been proved to be effective in developing some of creative thinking skills among mathematics department students, at faculty of education, Hodeida university in Yemen. Recommendations: 1) principles of TRIZ theory should be incorporated into the course of methodology of teaching mathematics which prospective teachers study at faculty of education. 2) Training courses for in-service teachers and cooperating teachers should be held at all faculties of education nationwide to help them be aware of TRIZ theory and methods of applying it to develop students’ thinking skills. 3) Improve mathematics curricula at different stages of education in such a way as to promote students’ thinking skills by applying TRIZ theory. Suggestions for further research: 1) conduct similar research based on TRIZ theory in other subjects. 2) Conduct other research to examine the effectiveness of applying TRIZ theory to promote other skills such as critical thinking skills. 3) Conduct a search combines Therese theory and strategies, such as the six hats thinking.
