Delay of Feedback and Its Effect on the Retention of Three Types of Computer-Assisted Mathematics Instruction.
Gay, Lorraine R.
Delay of feedback studies with animals or with tasks which are simple for human subjects have led to the common assertion that computer-assisted-instruction (CAI) systems should incorporate immediate feedback in order to maximize learning. However, studies using more complex learning tasks have suggested that delays of up to at least a day actually benefit learning. A study was designed to investigate the optimal feedback delay for different types of mathematical material in an undergraduate mathematics course taught by CAI. The results indicated that immediate feedback was not superior to delayed feedback, although the optimal delay is very much dependent on the type of material involved. The more complex the material to be learned is, the shorter is the feedback delay which can be tolerated without a decrement in retention. Thus, the implication of this study was that time-shared CAI systems need no longer be concerned about the resulting delays in input-output processes. (RH)
