Research on the Penetration of Mathematical Ideas and Methods in the Teaching of Primary School Mathematics Wide-angle "Matching Problems": A Case Study of the First Volume of the Second Grade of the People's Education Edition

Abstract

The "Compulsory Education Mathematics Curriculum Standards (2011 Edition)" clearly points out that the teaching of "mathematics wide angle" should highlight the penetration of mathematical ideas and methods, and the second grade is a critical period for cultivating students' mathematical thinking. This paper takes the first volume of the second grade of the People's Education Edition, "Mathematics Wide Angle - Collaborating (1)", and analyzes the 50 students of Class X of the second grade by using literature research method, action research method and questionnaire survey method, etc., to explore the infiltration of mathematical ideas and methods and their existing problems in the teaching process of "matching problems", and put forward corresponding solutions. After research, it is found that there are four problems in the current teaching, including unreasonable teaching time arrangement, single teaching structure design, imperfect teaching evaluation system, and low degree of fit between teaching objectives and "collocation" themes. Therefore, the optimization method is given from the following four aspects, the first is to dig deep into the implicit ideas in the textbook, the second is to improve and perfect the design scheme of the teaching process, the third is to establish a more complete teaching evaluation system, and the fourth point is to set the goals of education based on the development of students. The research results can provide some practical reference for the effective penetration of mathematical ideas and methods in the teaching of primary school mathematics from a wide angle, and help improve students' mathematical thinking ability and teachers' professional level.
