THE EFFECT OF USING THE MANTLE OF THE EXPERT STRATEGY ON ACHIEVEMENT AND DECISION-MAKING FOR FIRST GRADE INTERMEDIATE STUDENTS IN MATHEMATICS
This study aimsat measuring the effect of using the expert’s mantle strategy on achievement and decision-making for first-grade intermediate students in mathematics. The researchers has followed the semi-experimental approach with a post-test. The study sample consisted of (42) students divided into an experimental group of (21) students, who studied using the strategy and an expert gown and a control group, which consisted of (21) students. This sample studied in the usual way, and the two groups were matched in the extraneous variables.
The researcher prepared an achievement test consisting of (30) test items to measure students’ achievement after completing the teaching. And is a list of decision-making skills that included (42) skills, and verified its validity and consistency, and applied the two tests to the students of the experimental and control group at the end of the experiment that lasted (10) weeks, and after analyzing the data using the statistical program of SPSS for two independent samples, the researcher reached:
- There is a statistically significant difference between the average achievement of the students of the research group at a level of significance (0.05) for the benefit of the experimental group that studied mathematics according to the use of the expert's mantle strategy in the achievement test.
- The existence of statistically significant differences at the level of (0.05) in favor of the experimental group in the decision-making scale.
