AU - أبو مغنم، كرامي بدوي AB - This research aims at investigating the effectiveness of using PDEODE strategy for teaching Social Studies to develop geographical concepts and thinking skills and the tendency towards this field of study. The sample of the study consists of (62) first intermediate students in the Kingdom of Saudi Arabia, divided into two groups: experimental and control group. The experimental group was taught using the PDEODE strategy whereas the control group was taught using the traditional method. The experimental research method with semi-experimental design was used to achieve the objectives of the research and design its tools in terms of a geographical concepts test, a geographical thinking test and a scale of tendency towards geography. The findings of this research show that there are statistically significant differences at the level of (0.01) in the post application of the geographical concepts test, geographical thinking test and scale of tendency towards geography in favor of the experimental group students. The findings also show that the effect of employing PDEODE strategy is significant in developing geographical concepts, geographical thinking and the tendency towards geography. The research concludes with a set of recommendations and suggestions related to utilizing PDEODE strategy in the learning environment.
