الملخص EN

Thesis Objectives: The thesis aimed at investigating the effectiveness of using Self-Explanations Strategy in developing physical concepts and the awareness of future envisioning of secondary stage students.

To achieve the research objectives, the quasi-experimental approach was used through applying the experiment to two groups (the control and the experimental groups).

The sample comprised (51) students; (25) at first secondary term students in the experimental group and (26) students in the control group.

Thesis procedures: The scientific content of chapter seven, entitled "gravity" in the physics textbook for the first secondary grade students (second term), was structured and organized according to the philosophy and nature of Self-Explanations Strategy.

Then, two tools were prepared; the physical concepts test and the awareness of future envisioning scale.

The Validity and reliability of the two tools were applied through applying them on a pilot group of (30) students.

They were pre-applied, then the experimental group was taught using Self-Explanations Strategy and the control group was taught using the traditional method.

Then, the thesis tools were post-applied to get the raw scores to apply the statistical processing in order to get the results.Thesis results: The results revealed the effectiveness of Self- Explanations Strategy in in developing physical concepts and the awareness of future envisioning.

Whereas there statistically significant differences at (≤0.05) level were existed between the mean scores of the control and the experimental groups students in the post test of concepts as well as the future awareness scale in favor of the experimental group.
