The r esearch study presented here i nvestigated the eff ectiveness of a modified just-in-time s et of review modules covering algebra t opics in the context
of relevant calculus material. By administering these r eview modules via t he
online homework s ystem t raditionally used in this calculus course, we have
discovered a flexible, time-independent method for addressing gaps in background knowledge that also leads to a s tatistically significant increase i n
student achievement on the t opics of limits and the chain r ule. With limits
being an inherently difficult t opic f or first-semester calculus students t o master, the s uccess of t his t ool 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
