The Effectiveness of a Training Program Based on Creative Problem Solving Model (CPS) in Developing Mathematical Power for 8th Grade Students in Light of their Mathematics Achievement

This study aimed to reveal the effectiveness of a training program based on a creative problem solving model (CPS) in developing mathematical power for 8th grade students in light of their mathematics achievement. To achieve this goal, a training program was designed to focus on a set of mathematical ideas and skills in an algebra quantities unit using creative problem solving strategies. The researcher designed a test to measure mathematics power. The sample of the study consisted of 135 female eight grade students randomly selected from Dhahra governorate, which was divided into experimental and control groups. For testing the study hypothesis, data were  analyzed by analysis of covariance (ANCOVA 2X3) in which eta squared was obtained. The study revealed a significant difference (α=0.05) in the means between the experimental and control groups in the mathematical power test in favor of the experimental group
