The Construction Of Mathematics Teaching Cases Based On Case Teaching Method In Teacher Education

Teaching case is the carrier of communication theory and practice,and high quality teaching case is an important tool to carry out case teaching.In recent years,the construction of the teaching case has been from the initial legal,medical,management areas to the current areas of teacher education.In the field of mathematics teacher education,it held a national seminar about teaching case writing in education master's degree in degree teaching(mathematics)professional teaching case preparation in 2016,and the plan to build a case-base on mathematics teaching was presented at the meeting.However,so what about the current situation of constructing math teaching cases? How to construct a case of mathematics teaching? And what about the effect when using the case teaching method to carry out the practice of teaching the case test?In view of the above problems,I have discussed the case teaching theory such as case teaching,knowledge classification,information processing,situational awareness and the training goal of mathematics teacher education at first.At the same time,in order to understand the current situation of the construction of mathematics teaching cases,I conducted a survey of frontline primary and secondary school mathematics teachers from the cognitive and operational level.What is the theoretical basis and practical basis for constructing the case of mathematics teaching.On this basis,with reference to the mature management of educational case construction methods to put forward the construction process and method of mathematics teaching case,and construct the case of teaching content design and teaching activities.In the case of the practice test of case 1,the two classes of mathematics majors in Shanghai were regarded as the "experimental class" and "control class" to carry out case teaching and traditional teaching.In the process,from the students' classroom experience and knowledge to master the two dimensions,through the questionnaire survey,testing and interviews and other means,to evaluate the case 1.Through this research,the following views were obtained:(1)There is a lack of theory and other issues when the frontline mathematics teacher in the construction of the case.And it is need to clear the case construction process and methods,standardize the case building and other measures to promote the preparation of cases;(2)The construction of mathematical teaching case process: Looking for a theme,planing the plan;Cond-ucting school research,collecting information;Processing material,Structuring,and thinking to write;Forming the text,writing instructions;(3)There are significant differences in the four evaluations of "control class" and "experimental class" in "attention","confidence","relevance" and "satisfaction",and the "experimental class" Higher rating.And "experimental class" students to evaluate the classroom experience higher.It shows that the method proposed in this paper is helpful to construct a case of mathematics teaching with better classroom experience;(4)There are significant differences for "control class" and "experimental class" on the specific teaching content of the test data.And "experimental class" students better results.It shows that the construction of mathematics teaching case is helpful to master the theoretical knowledge of education and teaching;Mathematics teaching case can help students get a better classroom experience,more conducive to the mastery of knowledge,should strengthen and standardize the construction of mathematical teaching case library.It is expected that the construction process and methods proposed in this study will help to improve the theory and practice of mathematics teaching.
