استخدام برنامج كورت واثره في التفكير الهندسي لدى طالبات الصف الثاني المتوسط

Abstract

The sample consisted of( 74 ) female students from the second grade at Al-Yassamin middle school for Girls which belong to the Directorate of Education in Baghdad / the first Risafah ,for the second semester of the academic year ( 2014 - 2015 ) A.C , and Chapters VI , VII, and VIII of the math book scheduled for the second grade, section (F) consisting of (37) were selected to be the experimental group who were taught math material by CoRT Programme , and section (E ) consisted of (37) were selected student to be the control group, who were taught math material by traditional method.The researchers formulated behavioral objectives, the researcher studied both groups. These objectives covered the levels of (remembering, comprehension, application, analysis, synthesis) in Bloom's classification. The researcher prepared (40) lesson plan for each group included research topics, and prepared test, of geometric thinking test consisting of (30) items.The researchers used the equation of the alpha - Cronbach to calculate the reliability coefficient of geometric thinking test , the researchers also used the (t-Test) for two independent samples for data processing. The results were as follows:1) there is a statistically significant difference at the level of significance (0.05) between the mean scores of students of the experimental group and the control group for the experimental group in geometric thinking test and at every level of geometric thinking levels . The researcher concluded that the adoption of CoRT Programme have a positive impact in the geometric thinking in mathematics, the researchers put forward some recommendations and suggestions.
