The aim of the current research is identifying the effectiveness of a proposed training program in light of TPACK model to development the teaching performance of science student teachers, and the research group consisted of (43) teachers student in the Biology/Geology Department at the Faculty of Women for Arts, Science, and Education, The researcher used a one-group experimental design (experimental group), and the research tools consisted of both experimentation tools (a proposed training program in light of TPACK model , trainer's guide, and activity sheets) and a measurement tool (a teaching performance observation card in light of TPACK model), the research tools were applied preliminarily on the research group, then applying training program then applying the research tools afterward, then The research data was processed statistically, and The results revealed that there was a statistically significant difference between the average scores of the research group in the pre and post application of the teaching performance observation card in favor of post application , and This confirms the effectiveness of the proposed training program in the development the teaching performance of science student teachers, Based on these findings, a set of recommendations and proposed research topics were suggested.
