Research on strategies for improving mathematical sense of primary school students based on PBL model
Abstract
This paper focuses on PBL (Problem-Based Learning, problem-based learning) model to improve students' sense of math quantity, aiming to explore how to promote the formation and development of students' sense of math quantity through innovative teaching methods. This paper summarizes the core elements of PBL model and the compatibility between PBL model and mathematics sense, and analyzes the problems existing in the current cultivation of elementary school students' mathematics sense, such as the disconnection between theory and practice, the lack of students' initiative and participation, the limitation of evaluation system and the lack of teachers' guidance strategies. To solve the above problems, this paper puts forward the strategy of improving the mathematical sense of primary school students based on PBL model; Strengthen practical operation and experiential learning; Implement diversified evaluation system; Strengthen teacher training and optimize guidance strategies to ensure that teachers can deeply understand the PBL model and effectively guide students to develop a sense of mathematical quantity. The research in this paper not only enrichis the theoretical system of mathematical sense cultivation, but also provides operational guidance and suggestions for primary school mathematics teaching practice, which is of great significance for promoting the comprehensive improvement of students' mathematical literacy.
