Conclusion
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.
