Research On Teaching Design And Practice Of Junior Middle School Mathematics Proposition Based On TPACK

Under the background of deepening the information technology to boost the education and teaching reform,TPACK(Technological Pedagogical and Content Knowledge)is an important theory to promote the in-depth integration of information technology and subject teaching.Mathematics,as the main subject of students' study,plays an important role in the development of students.However,the analysis of the present situation of proposition teaching shows that the integration of information technology and proposition teaching is not satisfactory.Therefore,it is of great significance to carry out research on proposition teaching design from the perspective of TPACK.This paper mainly carried out the following research.Based on the analysis of the current situation of proposition teaching from the perspective of TPACK,it is concluded that the main problems are: the integration of information technology and proposition teaching is not in place;The integration of information technology and proposition teaching;The dislocation and offside of the integration of information technology and proposition teaching.In view of the above problems,the proposition teaching design based on the TPACK perspective is carried out.Based on the literature related to TPACK and proposition teaching design,the proposition teaching design principle from the TPACK perspective is proposed and the proposition teaching design mode based on the TPACK perspective is constructed.Then,according to the proposition teaching design from the perspective of TPACK,the author carried out the teaching of "the nature of primary function"--the image of primary function(2)--in grade 8 of Jiangsu Phoenix Science and Technology Publishing House,and used the methods of class comparison,questionnaire and teacher evaluation to carry out the teaching evaluation.The evaluation results show that the mathematical proposition teaching design based on TPACK perspective is helpful to students' learning of mathematical proposition,helps teachers teachers to have a deeper understanding of the proposition teaching of information technology integration,and effectively realizes the integration of information technology and proposition teaching.TPACK provides new ideas for mathematics teachers to carry out teaching design,and enables them to focus on mathematics teaching knowledge,mathematics knowledge of integrated technology,teaching method knowledge of integrated technology and mathematics teaching knowledge of integrated technology when carrying out teaching design.The proposition teaching design based on the TPACK perspective is not only of great value to improve the design process of the proposition teaching of mathematics,but also of great significance to further promote the effective integration of information technology and mathematics classroom teaching.
