The present study is an attempt to measure the effectiveness of using flipped classroom strategy in academic achievement and self-efficacy among female students of College of Education, Princess Nourah bint Abdulrahman University (PNU), Saudi Arabia. The study adopted the experimental method based on the two experimental and control groups, where the experimental group was taught through flipped classroom strategy, while the control group taught in the traditional way. Two tools were applied in this study: (Achievement Test and Self-Efficacy Scale). The sample consisted of two groups: one group is experimental and the other is control, both studying the course of (Classroom Management) in the first semester for the academic year 2016/2017. The results showed that the experimental group outperformed the control group in the post achievement test, as well as having a positive correlation between the students' post achievement test and their attitudes towards self-efficacy scale; indicating that the more scores the students get in achievement test, the more self-efficacy they have. In the light of the results, some recommendations have been made.
