Teaching Research On Mathematics Of Junior High School Based On History-Genetic-Principle

History-Genetic-Principle is a research method that belongs to the field of ge netics.Compared with the study of junior high school mathematics teaching and there are fewer cases of classroom empirical research related to History-Genetic-Pr inciple in China.This article examines the issues related to mathematics teaching in junior high schools from the perspective of History-Genetic-Principle.This paper is divided into four parts and six chapters.The first part includes the introduction of first chapter's and the second chapt er's definition and the review of the literature,uses the method of literature resear ch to define the"HPM"and"History-Genetic-Principle".The second part of the empirical research is based on History-Genetic-Principl e for junior high school mathematics in teaching problems,through the third chapte r which talk about the questionnaire survey,analyze the mastery of the history o f mathematics history in junior high school mathematics teachers and junior high school students;the fourth chapter is designing corresponding teaching cases,and giving relevant thinking on the design process based on History-Genetic-Principle.The fifth chapter will be designed teaching cases for junior high school math ematics teaching experiment,and make comments and reflections on the teaching experiment process and results.On the basis of the two parts we mention before,the third part proposes sug gestions for the design process and experimental process of junior high school ma thematics teaching based on History-Genetic-Principle.On the one hand,seven des ign principles are given from the perspective of instructional design;On the other hand,five attention points are put forward from the perspective of teaching imple mentation.The last part summarizes and prospects the study of this dissertation,and puts forward the insufficiency of research and the direction of further research.
