Research On Mathematics Teaching Design Based On TPACK Theory

Technological Pedagogical Content Knowledge is the necessary knowledge of teachers in the information age.It is the basis for teachers to use technology to improve the quality of classroom teaching.Teaching design ability is an important component of teachers' quality.Excellent teaching design is the basic guarantee for the success of classroom teaching.The purpose of this study is: understanding the process of integrating technology into mathematics teaching design,constructing a model of teaching design based on the TPACK theory,and realizing the effective integration of technology and mathematics classroom teaching.The following two questions were investigated:(1)what is the mathematics teaching design model based on TPACK theory?(2)what are the problems in the integrating information technology into mathematics teaching?First,through the literature search,the author understands,sorts and analyzes the previous research results on TPACK theory and mathematics teaching design,summarizes thedeficiency and superiority of existing research;Second,by participating in educational field experience,the author observed the excellent middle school mathematics teachers in the classroom teaching and analyzed two teaching designs which integrating information technology.Through classroom observation,the author understand the situation of teachers' teaching,students' learning,the mathematics classroom activities and interaction between teachers and students.Based on TPACK theory,a model for mathematics teaching design was constructed.According to this model,the researcher designed the lesson plan of Pythagorean theorem and implemented it in the classroom.The researchers collected data through literature research,classroom observation,interviews and video recording,and document collection.A model for mathematics teaching design based on TPACK theory was constructed and some mistakes which appear in the application of technology were summarized.The study found that:(1)TPACK theory provides a new perspective for mathematics teaching design,it has a guiding role in mathematics teaching design of the integration technology.At the same time,the knowledge structure of the teachers must have higher requirements.(2)The application ofmathematics teaching design based on TPACK theory to the classroom teaching practice can stimulate students' interest in learning,mobilize the enthusiasm of students,and improve teaching efficiency and teaching quality.(3)there are many misunderstandings in the teachers' application of information technology.The unreasonable application of technology has played a negative role in the teaching effect.(4)there are still some teachers rigidly adhere to the fixed teaching mode.Some teachers ignore the impact of technology on education and teaching in the information technology environment,or choose and use technology as a mere formality.
