Abstract EN

This study examined the effectiveness of using self-explanations strategy in physical concepts achievement and its related problem solving for the first year secondary students.

The sample of the research consisted of (54) students in the first grade of secondary stage, this sample was divided into two groups, i.e.

experimental group (28) students, control group (26) students.

The experimental group has studied through using self-explanations strategy and the control group has studied through the traditional method.

The researcher has used the following instruments: scientific concepts achievement test (knowledge- comprehension-application- analysis- synthesis - evaluation) in Motion and Newton’s Laws units and physical problem solving test.

The study had reached the following results:(1) There are statistically significant differences between the mean scores of the experimental group and the control group in the scientific concepts achievement test at the levels of knowledge, comprehension, application, analysis, synthesis, evaluation and whole achievement in favour of the experimental group.(2) There are statistically significant differences between the mean scores of the experimental group and the control group in physical problems solving test in favour of the experimental group.(3) There is a positive relation between physical concepts achievement and physical problem solving ,this rela tion is statistically significant with experimental group studied by using self - explanations strategy.

The results provide empirical support for the Effectiveness of self- explanations strategy; that is, self-explanations can stimulate new inferences, insight, acquisition of conceptual knowledge (facts-concepts-laws-theories) and procedural knowledge (applying conceptual knowledge in complex field as physical problems solving field).

Several recommendations were suggested in the light of the results.
