Design And Research Of Junior High School Geometry Based On TPACK Framework

As the third stage of the integration of information technology and curriculum development,teacher TPACK is one of the most popular research fields in educational technology.TPACK is different from the "constructivist learning centered",different from the"Teacher Center" of the traditional teaching thought,the core of TPACK is dynamic balance technology,subject knowledge and teaching knowledge,one of these factors changes,changes will cause other elements,so as to break the original balance of knowledge between,between the three mutual restraint and mutual construction,eventually reaching a new equilibrium.In recent years,the scholars as Ren Youqun,Zhan Yi in China as a representative for a lot of research on TPACK theory,but mostly limited to theory research,and its application in the teaching.Based on the investigation of junior high school mathematics teacher of geometry TPACK ability,trying to TPACK the research,combined with the geometry of junior high school students learning difficulties,micro class production model that is suitable for junior high school geometry teaching.Its purpose is to help teachers to reduce the pressure of teaching,improve teaching efficiency,and help students better understand the concept of geometry,geometry knowledge.To achieve the above goals,this paper has done some work as follows:(1)through the literature survey,the current research and the international TPACK relevant information on the theory and literature on the current teacher's ability to TPACK,and the degree of application of TPACK in teaching are summarized.(2)through the questionnaire survey and interviews,to understand the junior high school mathematics teachers' geometry knowledge of the TPACK level,and summarizes the characteristics of junior high school students learning and learning problems.(3)combined with the theory of knowledge classification and Bloom Meyer et al.,in the geometry knowledge types(CK)classification,summarizes the teaching strategies used in the classroom of junior high school geometry teaching technology(PK)and(TK),and CK,PK,TK correspondence,obtained TCK,PCK geometry and TPK the classification table,provides considerable convenience for teachers to produce micro class.(4)combined with the TPACK theory and the present situation of the micro teaching,we construct the-MG-TPACK model of the junior high school geometry.
