The research study presented here investigated the effectiveness of a modified just-in-time set of review modules covering algebra topics in the context
of relevant calculus material. By administering these review modules via the
online homework system traditionally used in this calculus course, we have
discovered a flexible, time-independent method for addressing gaps in background knowledge that also leads to a statistically significant increase in
student achievement on the topics of limits and the chain rule. With limits
being an inherently difficult topic f or first-semester calculus students t o master, the success of t his tool in context of t his t opic i s encouraging. With added
flexibility of dropping the j ust-in-time f eature, easy i mplementation i s another
positive aspect of these r eview modules. We hope that this study leads into
future research that offers new perspectives and insight regarding t he connections that students make between background mathematical knowledge and
