A Multi-level Remedial Teaching Design Based on Cognitive Diagnostic Assessment: Taking the Electromagnetic Induction...

Area of Science:

• Educational Psychology
• Cognitive Science
• Instructional Design

Background:

• Traditional one-size-fits-all teaching is less effective than differentiated approaches.
• Student learning levels vary widely within high school classrooms.
• Cognitive diagnosis theory offers a framework for understanding student knowledge gaps.

Purpose of the Study:

• To develop and implement a multi-level remedial teaching scheme for high school students.
• To assess the impact of this scheme on student learning outcomes.
• To identify and address common cognitive errors across different learning levels.

Main Methods:

• Utilized the deterministic inputs noisy and gate (DENG) model for cognitive diagnosis and student classification.
• Conducted cognitive diagnostic tests with 1,615 high school sophomores.
• Analyzed think-aloud protocols from 36 students to identify cognitive errors.
• Implemented a remedial teaching experiment with 258 seniors across three schools, comparing to a control group.

Main Results:

• Multi-level remedial teaching programs were designed based on identified cognitive errors.
• Students in the experimental group demonstrated significantly greater learning improvements than the control group.
• The assessment, classification, and teaching scheme preparation steps were found to be feasible and effective.

Conclusions:

• Multi-level remedial teaching is a feasible and effective approach for improving student learning.
• The developed scheme addresses diverse student needs and cognitive errors.
• This process provides a valuable reference for teachers across various subjects seeking to enhance instruction.
