数学教学中数感的培养策略研究现状及教学建议——基于关键词知识图谱分析

Research Status and Teaching Suggestions of Digital Sense Training Strategy in Mathematics Teaching—Based on the Keyword Knowledge Mapping Analysis

摘要: 近年来在数学教学中对学生数感的培养策略，一直是很多专家学者所关注的热点，本文基于CNKI文献数据库，对数感培养策略研究这一领域的部分学术期刊、学位论文，进行可视化分析。分析结果表明：目前小学生和小学数学课堂教学是主要研究对象，基于数学核心素养下的数感培养策略是研究的重点，对估算能力的训练为研究的热点。据此对我国未来数学教学中数感培养策略的发展提出四点教学建议：1) 重视对低年级学生数感的培养；2) 推广在实际生活中体验数感的教学方法；3) 加强数学核心素养在数感培养策略中的体现；4) 训练估算能力是有效培养数感的法宝。

Abstract: In recent years, the cultivation strategy of students’ sense of number in mathematics teaching has been a hot topic of attention to many experts and scholars. This paper, based on the CNKI literature database, studies some of the academic journals and dissertation in this field, and conducts visual analysis. The analysis results show that the mathematics classroom teaching of primary school students and primary schools is the main research object, and the training strategy of number sense based on the core literacy of mathematics is the research focus, and the training of estimation ability is the research hotspot. These are four teaching suggestions for the development of the training strategy of number sense in future mathematics teaching in China: 1) Pay attention to the cultivation of number sense of lower grade students; 2) Promote the teaching method of experi-encing the sense of number in real life; 3) Strengthen the embodiment of core mathematics literacy in number sense training strategy; 4) Training and estimation ability is a magic weapon to effec-tively cultivate the sense of number.
