The study aimed to measure the effectiveness of the constructive learning model (7E’s) in developing of systemic thinking and mathematical excellence skills among the seventh-grade students in Gaza. A semi-experimental design was used. The study tools included: teacher's guide, systemic thinking test, and mathematical excellence test in geometry. The sample of the study consisted of (94) seventh grade female-students in the directorate of education in eastern Gaza. It was divided into two equal groups: experimental and control, each has (47) students. The experimental group students learned geometry using the constructive learning model (7E’s) while the students of the control group learned it in the normal way. The results of the study showed a statistically significant difference in favor of the students of the experimental group, who used the (7E’s) constructive learning model in geometry. It also highlighted the effectiveness of this model in developing both systemic thinking and mathematical excellence. The study also showed a significant impact of the model on developing these two skills on students in the geometry and measurement unit, and a positive- strong correlation between the systemic thinking and the mathematical excellence of the students who used this model.
