Use Of Advance Organizers In The Junior High School Mathematics Teaching To Promote Students' Understanding Of Mathematical Concepts And Principles

Although our present's educational reform does not need to advocate Learning to accept, but not all are suitable for Discovery Learning. Meaningful Learning Ausubel advocated is still the most economical, most convenient, and most effective teaching way. Based on this Advance Organizer strategy's research is also very valuable. American psychologists Ausubel proposed Advance Organizer strategy based on Meaningful Learning theory. The strategy was put forward after proposed. Organizers concept first great development in the field of teaching in all subjects and in the subsequent preparation of teaching materials have been widely used. The Advance Organizer concept obtained the very big development, obtained the widespread application in various branches' teaching domain as well as in afterward teaching material compilation. Advance Organizer strategy has been concerned widely after imported into China in the end of the century. The educator also utilized this strategy in the teaching to carry on the massive experiments, and achieved good results. But this strategy also has the massive blanks in mathematics teaching's application.This article mainly discussed the Advance Organizer in the promotion of understanding of the effectiveness of mathematical knowledge, as well as the concrete strategy carrying on mathematics concept teaching and mathematics principle teaching using the advance organizer,and has done the related experiment.From Ausubel's meaningful learning theory,the article analyzed the Advance Organizer to understand mathematics concept to the student the promoter action.The article analyzed the advance organizer from the information processing psychology's angle to understand mathematics principle to the student the promoter action. And has formally carried on the concrete elaboration in the advance organizer's utilization link and the design.Not only in using the link on, the advance organizer may"advance", but may also"postpositioned", but may also in studies in the new content process to utilize. The different utilization link organizer plays the role can differ from. Advance organizer's type complex diverse, According to advance organizer's utilization link, The advance organizer's design may also divide into the introduction class correspondingly, the search class, the consolidated kind of three kinds. Because mathematics concept teaching and mathematics principle teaching's advance organizer's form has the similar place, after discussed mathematics concept teaching advance organizer's form in detail, when introducting mathematics principle teaching advance organizer's form, then does not have again the auspicious thin elaboration, only introduced two kind of most commonly used advance organizer's forms. Simultaneously in the advance organizer presented in the way to make the simple classification. The Advance Organizer presents in the way, in the operation is teacher's oral narration easily;may also be the written writing form, teachers' and students' operation activity; as well as multimedia presents. Finally, has done the experimental study separately to mathematics concept and mathematics principle's Advance Organizer 's effectiveness. Indicated through the experimental result, using appropriate advance organizer according to student's cognitive structure and new material will obviously promote the student to mathematics knowledge understanding.
