Ideally, r eviews created in accordance with JiTT would have been administered
no more than a f ew days prior t o when the associated calculus topics were covered in a l ecture. In this study, t he reviews were not implemented in a pure
JiTT manner. I n fact, one of the r eview assignments, namely t he composition
of functions review, was given 5 weeks prior t o t he chain r ule online assignment. The other review assignments were given roughly 1 to 2 weeks before
the associated online calculus homework was assigned (consult Table 1 for t he
exact timeline).
