Feedback Procedures in Computer-Assisted Instruction: Knowledge-of-Results, Knowledge -of- Correct-Response, Process Explanations, and Second Attempts After Errors

52 p.Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 1984.The relative effectiveness of six different feedback conditions in computer-assisted instruction was investigated. Ninety high school freshmen and sophomore algebra students were randomly blocked into six groups according to a mathematics achievement test. Each group completed a CAI program designed to teach an algorithm for solving algebraic equations of one variable, with each group receiving one of the following feedback conditions after errors: (1) knowledge-of-correct-response (KCR), immediate question review (IQR); (2) KCR, next question (NQ); (3) KCR, process explanation (PsE), IQR; (4) KCR, PsE, NQ; (5) knowledge-of-results (KR), IQR; or, (6) KR, PsE, IQR. The findings replicated earlier research in showing the benefit of KCR over KR, but KR with PsE was as effective as KCR in correcting errors. KR, IQR ("Wrong. Try Again.") was the least effective feedback procedure. Combining PsE with KCR did not produce an additive effect. Implications for educational research and practice are discussed.U of I OnlyRestricted to the U of I community idenfinitely during batch ingest of legacy ETD
