A Case Study On The Development And Influencing Factors Of MPCK Of Master Of Education In Educational Practice

In the 80 s of the last century,a famous American scholar,Schulman,first proposed the concept of subject teaching knowledge,PCK(Pedagogical Content Knowledge),in order to solve the lack of certification of teaching qualification certificate at that time.He thinks that PCK is an effective integration of teachers' subject knowledge and teaching knowledge in the process of teaching practice,that is,it can transform subject knowledge into the form of knowledge that students can understand.It is an important part of teacher's knowledge.While MPCK(Mathematical Pedagogical Content Knowledge)is the specific subject of PCK,PCK of mathematics teachers is the MPCK of teachers.As an important part of the curriculum of teacher education,education practice is not only a learning course for master of mathematics education,but also an important way to obtain and develop the master of mathematics education MPCK.So the purpose of this study is to explore the development of the MPCK of the master of mathematics education and the rapid development of the master of mathematics education after the practice of education,and to explore the main factors that affect the development of MPCK in the process of educational practice,in order to accomplish the goal of the educational practice to the maximum extent,and to give full play to the master of mathematics education for the master of mathematics education.The role of MPCK has made its own efforts,and has made some suggestions for developing MPCK of master of mathematics education.This article chooses three masters of mathematics education as the object of the case study.On the basis of the composition of the composition of MPCK and the two scholars of Li Miao and Ninglian Hua,we can observe the changes in the teaching of the master of mathematics education in the actual class by filling out the CoRe form and using PaP-eR to understand the master of mathematics education in the teaching practice.In the course of the development of the four dimensions about mathematics knowledge,general teaching method knowledge,knowledge about mathematics learning and knowledge of educational technology,the main factors that affect the development of MPCK in mathematics education are analyzed by interview after class.Through the comparative analysis,it is obvious that after the education practice,the MPCK of the master of mathematics education has developed rapidly in the two aspects of the knowledge of mathematics learning and the knowledge of mathematics.It is the most important factor to communicate with instructors,to observe the teaching class of other teachers,and to explain exercises to students.
