Research On The Strategy And Application Of Geometry Intuitive Ability Training Of Junior High School Students Based On Knowledge Mapping

As one of the core qualities of mathematics,intuitive imagination plays an important leading role in mathematics teaching.Visual imagination refers to geometric intuition and spatial imagination in compulsory education.At the same time,"compulsory education mathematics curriculum standard"(2011 Edition)clearly points out that in mathematics teaching,we should pay attention to the cultivation and development of students' geometric intuition and other ten core qualities.It also clarifies the importance of training students' ability of geometric intuition in mathematics learning from the perspective of program documents.Therefore,this study takes the eighth grade students as the research object,based on the knowledge map tool,designs the strategy of cultivating junior high school students' geometric intuitive ability,and carries out teaching practice,aiming at cultivating students' geometric intuitive ability.First of all,through combing the literature at home and abroad and in-depth classroom research in junior high school,this study constructs a geometric knowledge map based on the content of geometry in the eighth grade mathematics textbook published by Shandong Education Press.On this basis,the paper designs the strategy of geometry intuitive ability training for junior high school students based on knowledge map tool.The implementation of the strategy is divided into three parts: classroom introduction,classroom teaching and after class summary.Secondly,the quasi experimental research method is used to carry out a three-month teaching practice in the eighth grade plane geometry teaching.The experimental class adopts the strategy of cultivating junior high school students' geometric intuitive ability based on the knowledge map designed in this study,while the control class adopts the traditional teaching method instead of the knowledge map tool,and constantly optimizes and improves the strategy in the teaching practice,so as to better apply the strategy Teaching at the front line.At last,we collect the scores of geometric test questions and self-efficacy questionnaires of students for analysis.At the same time,we interview the teachers and select 12 students according to their high,middle and low scores to summarize the achievements of the research.This study draws the following conclusions:(1)the strategy based on knowledge map is effective and feasible;(2)the strategy can significantly improve the students' geometric intuitive ability,especially for the students with middle grades;(3)the strategy can significantly improve the students' self-efficacy.This provides a new way of geometry teaching for the front-line teachers and a new opportunity for the cultivation of junior high school students' geometry intuitive ability.
