The current research aimed to identify the effectiveness of a proposed program based on the engineering design process to develop some strategic thinking skills and motivation for achievement among professional diploma students to prepare teachers for schools of excellence in science and technology (STEM) at the Faculty of Education, Zagazig University, and in light of this, a research sample was selected consisting of (30 A student from one of the STEM students at the Faculty of Education, Zagazig University for the academic year 2019/2020 AD, and the research tools were applied to them (strategic thinking test - measure of motivation to achieve) beforehand, and the teaching of the research sample and after it was completed, the research tools were applied afterward, and the treatment of Data using appropriate statistical methods The results resulted in a statistically significant difference at the level (0.01) between the mean scores of the members of the research group in the pre and post applications of the strategic thinking test as a whole and in its sub-skills separately in favor of the post application, and the presence of a statistically significant difference at the level (0.01) between the mean scores of the group members. Research on the pre and post-applications of the Motivation Achievement Scale as a whole and its sub-dimensions each separately in favor of the post-application. It was also found that there is a positive correlation between students ’scores on the strategic thinking test and students’ scores on the scale and motivation for achievement. Some recommendations and proposals were presented in light of the results that have been reached. Keywords: Engineering design process (EDP) - Strategic Thinking - Motivation for achievement
