利用信息技术进行初中数学课前预习的研究

Research on Pre-Class Preview of Mathematics in Junior Middle School by Using Information Technology

摘要: 从我国教学改革的态势来看，教育信息化是教学改革的技术支撑，而凸显学生的学习主体地位，提高学生的核心素养则是教学改革的主线。课前预习是提升初中数学课堂教学效益与发展中学生数学学科核心素养的前提与基础。本文主要探究微课在课前预习中的应用，包括融入初中数学知识点中涉及的数学史相关内容、与实际生活相结合的事例、阅读课本进行预习过程中需要思考的问题等。并借助“问卷星”平台对学生预习情况进行及时反馈，形成初中数学“线上线下融合式”课前预习的设计框架。这些不但为学生的数学学习提供了方法策略，更能帮助教师更好地开展课堂教学，提高课堂效率。

Abstract: From the perspective of the situation of my country’s teaching reform, education informatization is the technical support of teaching reform, and highlighting the main role of students in learning and improving students’ core literacy are the main lines of teaching reform. Pre-class preview is the premise and foundation for improving the teaching efficiency of mathematics in junior middle school and developing the core literacy of mathematics for middle school students. This paper mainly explores the application of micro-lectures in pre-class preview, including the integration of mathematics history-related content involved in junior high school mathematics knowledge points, examples of combining with real life, and problems that need to be considered in the process of reading textbooks for preview. And with the help of the “Questionnaire Star” platform to provide timely feedback on students’ preview situation, a design framework for “online and offline integration” pre-class preview of junior high school mathematics is formed. These not only provide methods and strategies for students’ mathematics learning, but also help teachers to better carry out classroom teaching and improve classroom efficiency.
