小学数学“三段十步”改课的教研范式探析

The Exploration of the Research Paradigm of“Three Stages and Ten Steps”for Optimizing Primary Mathematics Lessons

“改课”是聚焦教师实践的研究范式,融备课、上课、说课、听课、评课为一体,通过连贯一致的“三段十步”支架,把教研员、特级教师等专家教师和普通教师、新手教师组成专业实践共同体,经历“想明白、说清楚、改到位、做出来”的过程,打开优秀教师和课例的“黑匣子”。改变专家引领方式,通过全程陪伴和帮扶,以及专家、同伴之间深度互动,采用“自荐+推荐+抽签”等方式,让所有参与者获益,“让多数人上好多数课”,大面积提高学科教学质量,促进教育的优质均衡。

“Optimizing lessons”is a teaching research paradigm focusing on teacher practice.It combines the processes of“preparing lessons,giving lessons,interpreting lessons,listening to lessons,and evaluating lessons”“Through a coherent“three stages and ten steps”framework,it gathers research fellows,special-grade senior teachers and other expert teachers and ordinary teachers and novice teachers to form a professional practice community,and go through the process of“thinking logically,speaking clearly,making changes in place,and doing properly”,opening up the“black box”of learning from excellent teachers and lesson examples.By changing the leading Way of experts and adopting methods such as self-recommendation,recommendation,and drawing straws,through full accompaniment and.assistance,as well as deep int eraction between experts and peers,all participants can benefit,and“most teachers could take most lessons well”.In these ways,the quality of subject teaching could be improved,and the balanced and high-quality education could be realized.
