Adding Immediate Feedback to Explicit Timing: An Option for Enhancing Treatment Intensity to Improve Mathematics Fluency

The primary purpose of intensifying interventions is to increase the effect of the intervention currently being delivered. However, there has been little empirical work completed that can provide guidance on selecting intensification methods. Because intensity can be modified in a number of ways that may differentially impact the time, effort, or resources required to deliver an intervention, it is important that systematic research is conducted that will assist practitioners in determining what methods serve to amplify intervention effects. This study evaluated the effect of the immediate delivery of accuracy feedback, as a method of intensification, when added to an explicit timing (ET) intervention. Results indicated that the addition of immediate accuracy feedback enhanced the effect of an ET intervention. Implications for these results and future research are provided.
