Study of the Influence of Pre-Organizers on Mathematic Achievement of Students

摘要

Background: Improving students' problem-solving abilities is a major, if not the major,goal of middle grades mathematics. The Pre-organizer strategy is an instructionaltechnique which involves deliberate introduction of certain concepts and sub-conceptscalled sub-summers in advance of the presentation of the actual learning material ortask in order to enhance meaningful learning and retention of the learning materialsperceived difficult to learners.Objective: The present research investigates the effect oflearning by using advanced organization and traditional learning on the achievement inmathematics. Therefore we have chosen 3 classes by random sampling from amongmechanics student Eyrie Islamic Azad university.one class (42 students) asexperimental1 group, one class (44 students) as experimental2 group and other class(43 students) as control group. Results: Per-test on mathematics was administered to 3groups. There was no statistical significant difference between the groups. Same subjectwere thought to 3 groups lasted one months. Experimental groups were thought bylearning using advanced organization and control group were thought by traditionalmethod. After one months and teaching of second chapter of the book, 3 groups tookpart in post-test. The results of comparisons revealed that: experimental groups weresignificantly better than control on mathematics learning. Also found that these who areinstructed bussed on method using advance organization at the beginning of eachchapter are highly benefited from educational development. Conclusion: One monthafter post-test, we gave the student mathematics exam .the exam show that this methodhas a positive effect on the educational development in mathematics.
