基于认知诊断的有效作业精准化设计

Precise Design of Effective Assignments Based on Cognitive Diagnosis

“双减”政策的颁布对义务教育阶段的作业提出了新要求,尤其强调在限定作业量的同时,发挥作业在诊断学情、辅助教学等方面的价值。本文立足于学校教育业态,提出一种基于认知诊断的有效作业精准化设计方法,即利用知识图谱、认知诊断等新一代智能技术,精准选择作业布置点并实现学情的高效诊断和推理。在此基础上,从“紧扣课标”“全面覆盖”“动态连贯”“丰富形式”四个方面阐述了有效作业精准化设计的方法和原则。进一步结合多年在一线中小学实践的经验,介绍了依托“智慧学伴”平台探索出的“四面-一线-四环”有效作业实践模式,以期为教育实践中的有效作业精准化设计提供参考。

The promulgation of the"double reduction"policy has put forward new requirements for assign-ments in compulsory education,especially limiting the amount of assignments while emphasizing its value in diag-nosing academic conditions and assisting teaching.Based on the school education industry,this paper proposes an effective assignment precision design method based on cognitive diagnosis,using knowledge graphs,cognitive diag-nosis and other new-generation intelligent technologies to accurately select assignment placement points and realize efficient diagnosis and reasoning of academic conditions.On this basis,this paper expounds the methods and princi-ples of precise design of effective assignments around the four aspects of"closely following the curriculum stan-dard","full coverage","dynamic coherence"and"rich form".Further,combined with many years of practical expe-rience in front-line primary and secondary schools,this paper introduces the"four sides-one line-four rings"effec-tive assignment practice model explored on the basis of the"Smart Learning Companion"platform,in order to pro-vide references for precise design of effective assignments in educational practice.
