Abstract EN

The current research aimed at investigating the impact of a proposed extracurricular program based on Integrating TRIS' Principles with TIMSS's skill activities on the achievement level, in light of the activities' domains, and on developing strategic efficacy and adaptive reasoning among elementary school female students.

The research followed the experimental methodology with one group, i.

e.

experimental group consisting of (41) students.

The research's measurement methods involved TIMSS -based achievement test and a test for strategic efficacy and adaptive reasoning.

The research findings showed statistically significant differences among the experimental group's average scores in the pretest and posttest of the achievement test in relation to the cognitive domain (knowing, applying, reasoning, as a whole and for each sub-level separately, and the content domain (numbers, algebra, geometry, data and probabilities, statistics), as a whole and for each sub-level separately, at a significance level of (0, 01) and with a statistically significant impact size.

Furthermore, the findings revealed a statistical difference among the experimental group's average scores in the pretest and posttest of the strategic efficacy and adoptive reasoning test at a significance level of (0, 01) and with a high statistically significant size impact.

In light of the research measures and findings, several recommendations and suggestions for further studies were highlighted.
