A Study On The Implimentation Of “Four Bases” Of Mathematics Instruction In Grade Four Of Primary School

Since the promulgation and implementation of "Mathematics Curriculum Standard(2011Edition) of Compulsory Education ", "four bases” of mathematics has become the focus and hot issue in the research of mathematics education in our country. Mathematics "four bases"refers to the basic knowledge of mathematics, basic skills, basic ideas and basic activities experience. At present, the research on mathematics "four bases" is mainly focused on the research of the basic idea and the basic activity experience of mathematics. There is no combination of the four bases to conduct classroom teaching research. This paper mainly studies how to implement mathematics "four bases" in the classroom teaching.This research mainly includes:(1) the connotation and classification of mathematics "four bases" are researched further on the basis of literature study.(2) It also puts forward the on the basis of theoretical and practical research, this paper also puts forward the framework of the "four bases" text interpretation in the middle stage of primary school, the classroom teaching framework and the teaching evaluation scale based on the concept of "four bases" and the study of theory and practice.The paper needs to clarify the starting point and height for teaching and compares the teaching material horizontally and vertically to confirm what basic knowledge and skills the students need to master before "four basses" text interpretation of mathematics is carried out;pay attention to the details of the teaching materials and confirm the basic ideas obtained in classes and the basic activity experience accumulated.According to the text interpretation of "four bases" of mathematics and the teaching method of guidance, the paper proposes the framework of classroom teaching and modifies it by experimental study to form classroom teaching framework based on the concept of mathematics "four bases". When carry out mathematics "four bases" teaching, one should pay attention to the creative situations, problems, exploration and practice, new knowledge and consolidation and expansion. But these five aspects are not fixed and teachers can improve them flexibly so as to optimize the teaching effectiveness.The teaching evaluation of mathematics "four bases" is carried out from two dimensions:teaching activities and mathematics "four bases". Mathematics "four bases" evaluation dimension is mainly carried out from the correct understanding and presentation of mathematical knowledge, the basic idea of mathematics and the presentation of mathematics basic activity experience.
