基于DELC的初中数学概念教学实践与研究

Practice and Research on Middle School Mathematics Concept Teaching Based on DELC

摘要: 深度学习是强调学生对知识深入理解、使用批判性思维接受新知、将新旧知识结合运用到新情境中的学习过程。基于DELC深度学习环路，笔者提出改进后的初中数学概念教学设计路线，包含“前端分析”“预备、激活先期知识”“获取与深度加工新知”和“评价与反思”四个流程。然后选取浙教版《立方根》章节，依据此路线进行教学实践，课后通过学生问卷调查学生深度学习情况。问卷分析表明，建构的深度学习路线及教学设计案例能达到较好的效果。

Abstract: Deep learning is a learning process that emphasizes students’ in-depth understanding of knowledge, acceptance of new knowledge by critical thinking, and application of old and new knowledge to new situations. Based on Deeper Learning Cycle, the author proposes an improved junior high school mathematics concept teaching design route, which is mainly divided into four processes such as front-end analysis, preparation and activation of prior knowledge, acquisition and deep processing of new knowledge and evaluation and reflection. The author selects the Zhejiang edition of Cube Root chapter, according to this route, to design teaching cases and teaching practice. After class, the deep learning situation of students is understood through questionnaires and other forms. Data analysis shows that the constructed deep learning route and teaching design cases achieve good results.
