The research aims to identify the effectiveness of the problem tree strategy in the development of multiple intelligences among preparatory school students. The sample consisted of two groups: one was the experimental group (30) students, the other was the control group (30) students, (Imam Ali Preparatory School) has been chosen from the research community represented by secondary and preparatory schools belonging to the Directorate of Education of babil Governorate/the center. The empirical research method was adopted as a methodology for conducting the research which includes an independent variable (problem tree strategy) and one dependent variable (multiple intelligences). The partial experimental design was chosen to control the research variables. before starting the experiment, the research groups were equalized for accurate results with the following variables: (time age calculated by months, the first semester grads of students, Raven's test for intelligence). After the parity between the two sets of research, the application requirements of plans, objectives, and tests were prepared for the two research groups. The data results were statistically analyzed by t-test for two independent variables. The results showed that the experimental group was superior to the control group according to the problem tree strategy in multiple intelligences.
