الملخص EN

The current research aims to: Identify the effectiveness of the instructional-learning design according to the concept-rich mathematics teaching model in the spatial ability of middle school students To achieve this goal, an educational-learning design has been prepared according to the steps of the (ADDIE) model for building educational designs, which includes four stages: (analysis, preparation, design, development, implementation, evaluation).

To achieve the objectives of the research, the following null hypothesis were formulated: - There is no statistically significant difference at the significance level ( ) between the mean scores of the students of the experimental group who will study the material according to the instructional-learning design and the students of the control group who will study the same material according to the usual method in the spatial ability test.

The researcher used the following statistical methods to reach the results of the research: T-test for two independent samples, the equation for the difficulty coefficient for the objective items, ) 708 (.

the equation for the power to distinguish the objective items, the equation for the effectiveness of the wrong alternatives, the equation for KR, and it was reached The researcher leads to the following results: - There is statistically significant difference at the significance level ( ) between the mean scores of the students of the experimental group who will study the material according to the instructional-learning design and the students of the control group who will study the same material according to the usual method in the spatial ability test for the benefit of the experimental group.
