Abstract:
The research aims to identify the effectiveness of employing the strategy of education for understanding in the skills of mathematical proof among students of the fifth grade of applied science. The researcher selected the study sample of students from the middle of the Tigris for girls and chosen deliberately and their number (132) students distributed randomly four divisions, and randomly selected Division (B) to represent the experimental group taught according to the strategy of education for understanding by (30) students, and chose the Division (D To represent the control group, the traditional method was used with (32) students. The researcher prepared a test of mathematical proof skills consisting of (30) paragraphs. After completing the research experiment, the researcher found that the experimental group studying in accordance with the strategy of education for understanding in the post-test in the mathematical proof skills is superior to the control group which is taught in the normal way.
