This study aims at investigating the effect of an educational program supported with illuminations on problem solving and spatial ability among seventh grade students in Palestine. The Quasi-experimental design based on experimental and control groups was used in the study. Thus, the subjects of the study were (67) students from two sections, section (A) was selected randomly as an experimental group and exposed to the educational program supported with illuminations, section (B) was selected randomly as a control group and exposed to the ordinary instructional program. To achieve the aims of the study, three instruments were used for data collection: the educational program supported with illuminations, a test for measuring students' mathematical problem solving and a scale for measuring students' spatial ability. The results showed that there is a significant difference in problem solving among seven grade students in Palestine, in favor of the educational program and there is a significant difference in spatial ability among seven grade students in Palestine, in favor of the educational program. Based on the result, the researchers recommended the adoption of this study results, recommendations and it's educational program as a response for the effect of educational software on developing problem solving and spatial ability among the students, the necessity of training math teachers on using illuminations as programmed ones and the necessity of giving students chances to learn math through interactive educational software and enabling them to construct and represent math concepts.
