The goal of this study is to develop 9th grads students’ higher order thinking skills (i.e. Critical and Creative thinking) in the topic of analytic geometry. To achieve this goal, the researchers expanded (this expansion was suggested by Krulik and Rudnik, 1999) the Content of George Polya’s final heuristic, looking back (Polya, 1973). The expansion include three additional areas, namely: “What’s another way?”,“What if…?”, and “What’s wrong?”. The findings indicated the validity and effectiveness of these areas in developing students’ higher order thinking skills, thus, evidence supports previous claims (Krulik and Rudnik, 1999) that a post-heuristic level exists after George Polya’s final heuristic (“looking back”) and that level renamed Reflect (or After-the -Answer ) .Thus reflect level can encourage Students’ to develop critical and creative thinking skills.
