基于认知诊断视角的数学补救教学

Mathematics Remedial Teaching Based on Cognitive Diagnosis Perspective

补救教学是教师通过针对性的认知诊断测试,发现学生在某一单元或章节中存在的问题,从而设计相应的教学活动,帮助学生查漏补缺,进一步通过测评,促使学生实现教学目标的过程。基于认知诊断理论形成的补救教学包括明确补救对象、诊断补救病灶、实施补救过程和评价补救效果四个环节。教师可以通过教学目标层次分析,采用认知诊断测试,厘定学生"病灶"并进行归因,最终开展补救教学。认知诊断视角下的补救教学立足于学生的认知结构,能通过认知诊断找出学生的病灶所在,让不同的学生在现有基础上有所提升,从而提高教学的精准性。

Remedial teaching is a process by which teachers find out the problems existing in a certain unit or chapter through targeted cognitive diagnostic tests,so as to design corresponding teaching activities,help students to find gaps and make up for them,and further promote students to achieve their teaching goals through evaluation.The remedial teaching based on the cognitive diagnosis theory includes four parts:defining the remedial object,diagnosing and repairing the lesion,implementing the remedial process,and evaluating the remedial effect.Teachers can analyze the level of teaching goals,use cognitive diagnostic tests,determine students’“esions”and attribute them,and finally carry out remedial teaching.Remedial teaching of cognitive diagnosis is based on the cognitive structure of students,and can find out the focus of students through cognitive diagnosis,so that make different students havefurther improvement,so as to improvethe accuracy of teaching.
