The Teaching Research Of Middle School Mathematics Optimization Learning Case Design

With the further development of the new curriculum reform, all kinds of teaching modes appear one after another, learn case study because of its great achievements is pursuitedby many schools. But due to the low design quality and the improper implement of learning case, the negative influences are growing,so it is questioned."The direction of case study"becomes the focal point of the present moment. In this paper, aiming at the problems in middle school mathematics learning problems existing in the design, trying to answer "The direction of case study".In theory, this paper starts from the meaning of learning from the case, on the basis of mathematical learning case, to compare many different point of views and put forward in this study mathematics learning case connotation, form a research topic.Second, according to the research topic, focus on combing study case in teaching and learning problems and confusion and analyze the root cause, and put forward the problems that the teaching case design should be thought. In practice, this paper expounds the lecture "draft" and "336" guide learning pattern, fully affirmed the guiding case in improving the prominent role of students learning style, and points out its existing problems and deficiencies. Studies have found that learning case design lack of theoretical guidance, design freely, problem sets the serious; In implementation, improper use, lack of effective organization, guidance, counseling.Based on the new achievements of the current effective teaching, aimed at the learning problems and confusion of the current mode, this paper put forward the basic idea of optimization design of middle school mathematics learning case, summed up as "1234567".The optimization design centered on students’learning to the students’learning case"learning"as the center, seize the two fundamental elements of the teachers and students understand the article3the principle of the teaching; Accordingly, put forward the "four principles and five strategies" of guiding case optimization design; To effectively carry out the optimization principles and strategies, put forward the effective implementation of study case"six methods"and"seven steps". Then, under the guidance of optimization principle and strategy, aimed at the high school image and nature of the exponential function content, combined with some famous universities’ learning case specific optimization design of mathematical concepts, recitations, recitation classes.How about the effect of the optimized learning case? Teaching experiment research shows that the"five major strategies"as a whole can significantly improve the students’ learning effect and efficiency, significantly reduce the cognitive load of students’ learning. How about the value and the meaning of each strategy? Combined a closed questionnaire with open-ended questionnaire to make survey analysis.the results show that the strategies of target navigation strategy and multivariate evaluation can promote students to build up objective sense when studying,raise the positive emotions of mathematics study; Package information strategy can low the students’cognitive load of learning; Academic cooperation needs to be independent after the first cooperation, the existed students learning habits and teachers’ level of understanding the application of autonomy and cooperation both effect the strategy. Topic group variant strategies put forward higher requirements for teachers, teachers’ mathematics quality influence the effective implementation of the strategy.Optimization strategy can provide theoretical reference and practical guidance for the middle school mathematics learning. But with the new achievements of effective teaching being pushed, effective teaching strategy for the optimization strategy of the learning case also needs to, constantly supply and perfect, enrich its connotation, strive to pursue better learning case design^realize better learning effect、efficiency and effectiveness.
