Research On The Effective Teaching Of "figure And Geometry" In Junior Middle School Mathematics

Effective teaching is the evergreen subject of the school.Geometry is an intuitive abstraction of the objective world and a part of the mathematical quality of modern citizens.The curriculum standard of 2011 edition has detailed regulations on the teaching of graphics and geometry in junior high school.The core literacy theory puts forward new requirements for the effective teaching routine.This paper is divided into six chapters.The first chapter is the introduction.Explain the background and significance of the topic,from the position of the subject,the characteristics of the compilation of teaching materials,the requirements of entrance examination,etc.The research of this paper is based on the theory of constructivism and the theory of the zone of recent development.Effective teaching is to improve the efficiency of different teaching methods,to provide students with modern and benign teaching methods.Define relevant concepts.The second chapter is a survey of students' learning status,and a brief analysis of the survey results.The third chapter is the teaching content analysis of graphics and geometry.According to the routine teaching,it is divided into three parts: concept teaching,theorem teaching and problem solving teaching.In the part of problem-solving teaching,the author discusses the calculation of geometric quantity,geometric transformation and dynamic geometry.The fourth chapter is teaching suggestions.Focusing on the five key points of effective teaching: clear teaching,diversified teaching,task orientation,guiding students to invest in learning,and learning success rate,this paper discusses the teaching content in sections.The fifth chapter provides a complete teaching case.Chapter 6 reviews and prospects the research,summarizes the experience and shortcomings.In teaching,teachers should improve students' interest in learning,impart basic knowledge efficiently,improve teaching methods,cultivate students' geometric intuition,and guide students to change their learning methods.Considering the reality of the school,the reliability of experimental teaching needs further study.In the evaluation index of effective teaching,the author has not made a breakthrough.I look forward to your guidance and improvement.
