الملخص EN

This study aimed at investigating the effect of subject unit, which had designed according to the twenty-first century skills on mathematical achievement and thinking.

the purposive study sample consisted of (49) students (male) at seventh grade.

The study sample was divided into two groups: experimental and control.

The experimental group consisted of (25) students who were taught by using of subject unit, which had designed according to the twenty-first century skills whereas the control group consisted of (24) students who were taught by using the traditional unit.

The results indicated that there were significant statistical difference at (α = 0.05) between the two means for the scores of students' mathematical achievement attributed to subject unit for the benefit of the experimental group.

furthermore, there were significant statistical difference at (α = 0.05) between the two means for the scores of students' mathematical thinking attributed to subject unit for the benefit of the experimental group.

The results indicated that there were significant statistical difference at (α = 0.05) between the mean for the scores of students' immediate achievement and the mean for the scores of students' postponed achievement of the experimental group, for the benefit of the postponed achievement.
