标题：THE EFFICACY OF A PROPOSED STRATEGY BASED ON THE (MARQUQRD) MODEL, ONE OF THE KNOWLEDGE MANAGEMENT METHODS IN THE ALGEBRAIC THINKING SKILLS OF THE SECOND INTERMEDIATE GRADE STUDENTS
摘要：The aim of the research is to identify the effectiveness of using a proposed strategy according to the (Marquqrd) model in the algebraic thinking skills of second-grade intermediate students in the schools of the General Directorate of Education in Babylon. To achieve the goal, the following null hypothesis was formulated: There are no statistically significant differences at the significance level (0.05) between the mean scores of the students of the experimental group, which were taught using the proposed strategy according to the (Marquqrd) model, and the control group that studied in the usual way in the pre-post test of algebraic thinking skills. The research community, which represents the middle and secondary schools for boys within the General Directorate of Education in Babylon, was identified, and the Yahya bin Zaid (p.) middle school was randomly selected, and the research sample consisted of (67) students from the second intermediate grade students, and two groups were chosen randomly, with (33) students for the experimental group, and (34) for the control group. For the purpose of collecting data for the research, a test of algebraic thinking skills was built, as the test in its final form consisted of (24) items of the objective type, multiple-choice. The appropriate statistical analyzes were carried out (difficulty coefficient, ease, discrimination coefficient and effectiveness of the alternatives), and the psychometric properties were ascertained. After the statistical tools were chosen to analyze the results of the application of the test, such as using the associated analysis of variance (ANCOVA), the results indicated that: - 1- The students of the experimental group outperformed the students of the control group in the test of algebraic thinking skills. 2- The use of the proposed strategy according to the (Marquqrd) model led to an improvement in the algebraic thinking skills of the students of the experimental groups compared to the students of the control group.
