| The introduction teaching of plane geometry is an important part to guide the freshmen adapt to junior high school learning of plane geometry. Geometrical language is said simply but meaning clearly. In the first stage of geometry learning, a large number of geometrical language, and asked to use geometrical symbol, narrative and correctly understand the language, etc., so that students have difficult emotions.The thinking of geometry learning is rigorous and justified. And this is more difficult for junior high school students who just begin to contact with geometry. As a teacher,how to guide, it is particularly important to let the students do a good job in the first step.The main purpose of this study is through the literature analysis method,classroom observation, students’ homework analysis, questionnaire, interview method,to discuss the freshmen students’ difficulties and obstacles at the beginning of the plane geometry learning. According to the students’ test case after the completion of the basic examination, analyze the geometry problem from two aspects of investigation, the difficulty of knowledge points. Statistics students’ answers, to conclude the students’ master degree to the corresponding knowledge and determine the difficulties in geometrical knowledge learning. In this way, we can draw students’ difficulties of geometrical knowledge, but the psychological factors, their study habits and learning attitude factors that causing difficulties in geometrical knowledge learning cannot be inspected. In order to diagnose the students’ learning difficulties caused by individual subjective factors, I use the methods of questionnaires and interviews. I use the classroom observation and operation analysis to diagnosis knowledge factors and their study habits and learning attitude factors. Factors can be divided into intelligence factors and non-intelligence factors and teacher factors.At last, through literature analysis method, and the author’s own teaching experience, I will explore the corresponding teaching strategies and teaching advice. Teaching strategy mainly put forward from different ways, such as teachers, cultivating the students’ interest in geometry, training the ability of different aspects of the geometry.This paper not only can help students have a good introduction to plane geometry learning, but also can provide reference for first-line teachers’ teaching, therefore, it has a certain practical value. |
