Using Postfeedback Delays to Improve Retention of Computer-Based Instruction

Self-pacing, although often seen as one of the primary benefits of computer-based instruction (CBI), can also result in an important problem, namely, computer-based racing. Computer-based racing is when learners respond so quickly within CBI that mistakes are made, even on well-known material. This study compared traditional CBI with two forms of CBI designed to reduce computer-based racing: incentives/disincentives and postfeedback delays. All three formats were evaluated in terms of both performance and satisfaction using a between-group repeated measures design with pretest and posttest. Dependent measures included posttest scores and satisfaction questionnaire ratings. Posttest scores favored the use of postfeedback delays to improve learning over incentives/disincentives and control conditions. Postfeedback delays negatively affected satisfaction in comparison to the control condition, although no satisfaction differences were found between incentives/disincentives and postfeedback delays.
