A MPCK Case Study Before And After A Full-time Mathematics Education Master's Internship

The purpose of this paper is to explore the influence of mathematics education internship on MPCK and its key factors.For this reason,the article takes a full-time master of education as the research object,first analyzes the full-time mathematics education master's education internship before and after the internship.The MPCK level,then from the lectures,preparation,lectures,teaching reflections,follow-up discussions,corrections and test papers,counseling and answering questions,respectively,to study the key factors and reasons for promoting MPCK changes.The specific research questions are as follows:(1)What is the MPCK of the teacher before the education internship?(2)After the education internship,what is the teacher's MPCK?(3)What is the change in MPCK of teachers after an educational internship?(4)What are the key factors affecting the knowledge of mathematics teaching content in educational practice?For the research problem,this paper mainly uses text analysis,interview method and classroom observation method.In the many cases of full-time mathematics education masters,different types of concept classes,proposition courses,exercises,and review classes were selected as examples.Through research,the following conclusions are drawn:(1)Educational internship has a positive effect on MPCK,a full-time master's degree in mathematics education,especially in the knowledge of students,curriculum knowledge and teaching strategies.(2)Listening,preparing lessons,trying to talk and counseling Q & A The educational internship is the main factor affecting the knowledge of mathematics teaching content.Therefore,the following suggestions are proposed:(1)establish a good student MPCK case library;(2)focus on communication with the instructor in the educational internship;(3)correctly grasp the knowledge of mathematics teaching content.
