小学数学同课异构教学循证教研流程与实践——以《稍复杂的分数乘法实际问题(1)》为例

Evidence-based Teaching Research Process and Practice of Heterogeneous Teaching in Primary School Mathematics:A Case Study on"Slightly Complex Practical Problems of Fractional Multiplication(1)"

小学数学同课异构是教师教研活动的常见形式之一。以往的同课异构教学研究偏向基于经验的课堂观察,缺乏基于数据的循证教研。从经验比较到数据循证,能让小学数学同课异构所蕴含的专业发展力量走向深刻。基于数据的小学数学同课异构教学循证教研流程包括问题导向、循证设计、收集数据、对话共议、证据迭代五个部分。以《稍复杂的分数乘法实际问题(1)》一课为例,探究了小学数学同课异构教学循证教研的具体步骤。小学数学同课异构教学循证教研要注意数据服务教研、人机协同教研、理论联系实践。

Lesson with heterogeneous of primary school mathematics is one of the common forms of teachers'teaching research activities.However,in the past,the heterogeneity of the same class favored experience-based classroom observation and lacked evidence-based teaching research based on data.From empirical comparison to data evidence-based,it can make primary school mathematics heterogeneous in the same class contained Professional development force go profound.The evidence-based teaching research process of heterogeneous teaching in primary schools based on data includes five parts:problem-oriented,evidence-based design,data collection,dialogue and discussion,and evidence iteration.Taking the lesson of"slightly complex practical problems of fractional multiplication"as an example,the author explores the specific steps of heterogeneous evidence-based teaching research in primary school mathematics.The heterogeneous evidence-based teaching research of primary school mathematics should pay attention to data service for teaching research,human-machine collaborative teaching research,and putting theories into practice.
