The Effect of Using the Mental Maps on the Academic Achievement in Mathematics among the Educable Intellectually Disabled Students in Rafha Province

The study aims at investigating the effect of using the concepts mapping on the educable intellectually disabled students’ academic achievement in Rafha province in the Kingdom of Saudi Arabia. The researcher used thetwo-group experimental design with experimental and control groups. The study sample is restricted to the educable intellectually disabled students in the fifth grade inRafha province in 2019. The sample consists of 18 students distributed into an experimental group with eight students and a control group with ten students. The researcher prepared the educational plans using mental maps for the two groups in addition to an academic achievement exam. The reliability wasfound by using the Kuder-Richardson Formula,and the Reliability Value was(0.90).By the end of the experiment, tests were conducted upon the two groups. Afterstatistically processing the data using the t-test fortwo independentsamples, the resultsshowed the existence of statistically significant differences between the mean of the experimental group which studied using the mental mapping of concepts and the mean of the control group which studied using the ordinary learning methods in favor of the experimental group. Thus, the researcher highlyrecommends the using of the conceptsmapsin teachingthe educable intellectually disabled students.
