The Effect of Teaching a Geometry unit , according to an Expert on the Mantle in Achievements and Motivation Toward Learning Mathematics , at the 6th grade students in Jenin Schools.

This study aims to identify the effect of teaching the unit of "Geometry" according to an expert on the Mantle in measuring the achievements and motivation toward mathematics learning mathematics at the 6th grade students in Jenin Schools . In short, it is an attempt to answer the main question which is what the effect of teaching the unit "Geometry" by using the Mantle of the Expert in measuring the achievements and motivation toward learning mathematics by sixth graders in the schools of Jenin district. To answer the question of the study and to test hypotheses the researcher used the experimental methodology . Further , he applied it on a population of sixth grade male students . Besides, he chose two schools in the region of Jenin focusing on the sixth grade in its two sections . Further, the first group was the experimental group , which was taught by using the Mantle of the Expert .On the other hand , the other group was the control group which wasn’t taught by traditional methods . In addition , this study was done during the first semester of the scholastic year 2015-2016. The following tools were applied on the sample of the study : 1- A preparation memo according the Mantle of the Expert to be used in teaching the unit of "Geometry" for the experimental group . 2- An achievement test was given after the students have finished the unit of "Geometry" . 3-Motivation Toward learning mathematics scale to measure the students motivation towards learning mathematics before and after the Mantle of the Expert. One way ANCOVA was used to test the difference between the means of achievement and motivation, Pearson coefficient was used to test the relation between the achievement of the students and their motivation towards learning mathematics . The main results of this study can be summarized as the following 1. There is a significant statistical difference (α = 0.05) between the means of the students of the 6th graders who were taught using the Mantle of the Expert (the experimental group), and the control groups who were taught using the traditional way based on the achievement. The results were in favor to the experimental group. 2. There is a significant statistical difference (α = 0.05) between the means of the students of the 6th graders who were taught using the Mantle of the Expert(the experimental group), and the control group who were taught using the traditional way based on level of conceptual knowledge. The results were in favor of the experimental group. 3. There is a significant statistical difference (α = 0.05) between the means of the students of the 6th graders who were taught using the Mantle of the Expert(the experimental group), and the control group who were taught using the traditional way based on level of procedural knowledge. The results were in favor of the experimental group. 4. There is a significant statistical difference (α = 0.05) between the means of the students of the 6th graders who were taught using the Mantle of the Expert (the experimental group), and the control groups who were taught using the traditional way based on level of problems solving. The results were in favor of the experimental group. 5. There is statistically significant at (α=0.05) between the means of the motivation of the students in both groups due to using different teaching methods (using the Mantle of the Expert or not using it). The results were in favor of the experimental group which studied the unit of "Geometry" by using the Mantle of the Expert . 6. There is a statistically significant relation between the achievement and the sixth graders motivation towards learning math . Based on the previous results, the researcher recommended the following: 1- Make it possible for schools to have a special classroom for teaching math classes by using the Mantle of the Expert . 2- Training teachers use the modern teaching methods including Mantle of the Expert . 3- Preparing studies about using the Mantle of the Expert in teaching other subjects other than geometry such as fractions, algebra and other mathematical subjects .
