The research aims to identify the effectiveness of using the Kolb’s model to develop the physical reasoning and perceived self-efficacy of second-grade students, and the researcher prepared the research tools of physical reasoning test and the perceived self-efficacy scale, and the experimental approach was used as a semi-experimental design with two equal groups a control group of their number ( 35) A student and an experimental group of (35) students in Al-Aslouji Joint Secondary School in the Zagazig, Sharkia, and the following results were reached: 1-There are statistically significant differences between the mean scores of students of the experimental group and the control group in the post application of the physical reasoning test as a whole and in its sub-dimensions separately for the benefit of the experimental group. 2- There are statistically significant differences between the mean scores of students of the experimental group and the control group in the dimensional application of the measure of Perceived self-efficacy scale as a whole and in its sub-dimensions separately for the benefit of the experimental group. 3- There is a positive correlation between the experimental group students scores in the dimensional application of the physical reasoning test and the perceived self-efficacy scale.
