Analysis of teachers' implementation logs and a postimplementation survey measuring self-reported instructional behavior. The report concludes "there is no incremental cost of teacher time for ASSISTments above business-as-usual instruction," reflected as negative teacher opportunity cost in Table 1.

"Statistically significant differences were observed in the amount of time dedicated to homework practices in the classroom and in planning time to support instruction."
