Practical Research On Reasoning Ability Of Junior High School Geometry Deduction

Geometric deductive reasoning ability, actually is embodiment of students logical reasoning ability, independent thinking ability, innovation ability, is a complex ability. How in the teaching of training students’ geometry deductive reasoning ability, is still puzzled the teachers a urgent problem.This study aimed at to cultivate students’ deductive reasoning ability to provide feasible method. Through the methods of questionnaire and test, understand current junior middle school students’ interpretation of the reasoning ability of the relevant circumstances, by using 8 kinds of strategies in teaching and effectively improve students’ geometry deductive reasoning ability. The main research results are as follows:First, the main cognitive difficulties of the students in the geometry deduction and the main reasons are:1, the logic of the relationship between the geometric knowledge appear confused2, the understanding of the rotation is not strict enough3, for the understanding of the symmetry is not deep enough4, for the translation of the understanding of great difficultySecond, implement and strengthen the teaching strategy, and effectively train students to deduce and deduce ability.1. Lead students to be good at discovering the knowledge points contained in the title and use themThrough practice and exploration of this study found that only the students master the basic geometric model and apply what they have learned, you can greatly enhance the solving speed of geometric problems, but also can rapidly improve the students ability of deductive reasoning.2, pay attention to the problem solving ideas and reflect on the summaryOnly by analyzing and studying the relationship and the differences between the knowledge points, the associative space of the deduction reasoning will be more extensive, and the flexibility of thinking will be enhanced.According to the research results, the following suggestions are put forward.:1, mobilize the enthusiasm of students is the premise of the ability to train the deductive reasoning.2, the stage of the students to develop the deductive reasoning ability.3, in the teaching of 8 kinds of teaching strategies to strengthen the students’ ability of deduction reasoning.
