The Benefits of Feedback on Computer-Based Algebra Homework
This study compared homework as usual (with no feedback until the next day) with web-based correctness feedback. There was a reliable 10% improvement in student learning.
Condition 1- no-feedback
Condition 2- correct answer feedback
informs the student of the correct response
Provides no information about the student's response
Condition 3- explanation feedback
informs the student of the correct response
Condition 4- try again feedback
provides some explanation for why a response is correct
allows one or more additional attempts to try again.
Feedback resulted in higher posttest scores that no feedback, and this was true regardless of feedback type. On transfer items, correct-answer feedback has positive effects for low-knowledge students, but neutral effects for higher-knowledge students. Results suggest the provision of basic feedback on computer-based homework can benefit novice students' mathematics problem solving.
