In this study, the researcher attempted to monitor rate of speaking, as well as accuracy, lexical density, lexical complexity, and the use of academic vocabulary over a five week period using YackPack, to determine if the above features are useful indicators for judging fluency, as well as to determine whether YackPack is an effective tool to use for AE classes speaking homework assignments.
Over all, YackPack appears to be an effective tool as it increases intrinsic motivation, and students can use it at their own leisure when not faced with fatigue and other cognitive strains. Unfortunately, there still seems to be a problem with getting full participation, either due to a lack of technical expertise or an overall willingness to participate.
