先行组织者理论下的初中数学单元导语教学研究

Research on Introductory Teaching of Junior Middle School Mathematics Unit under the Theory of Advance Organizer

摘要: 单元导语作为每个单元学习内容的“航标”，是对整个单元的高度浓缩与总结。教师如何利用好单元导语开展单元教学，直接影响着学生对于这一单元内容的整体认识与理解。本文基于先行组织者理论对单元导语进行探索研究，提出要借助“固着点”功能，按照“宏观–微观–宏观”的思路，采用“纵深式同化”和“扩散式同化”教学策略来设计单元导语教学，以期丰富教师和学生对单元导语的合理应用与全面理解。

Abstract: Unit introduction, as the “beacon” of each unit’s learning content, is a highly condensed and summarized whole unit. How teachers make good use of unit introduction to carry out unit teaching directly affects students’ overall cognition and understanding of the content of this unit. Based on the advance organizer theory, this paper explores the unit lead and proposes to design the unit lead teaching with the help of “fixed point” function and the teaching strategies of “deep assimilation” and “diffuse assimilation” according to the thinking of “macro-micro-macro”, so as to enrich teachers and students’ reasonable application and comprehensive understanding of the unit lead.
