Table 2 Temporal measures
Measure | Summary |
|---|---|
Completion time (minutes) | The amount of time it took students to complete the Skill Builder. It was computed by subtracting the timestamp when a student started solving the first problem from the timestamp when a student completed the last problem in the Skill Builder. |
Total time-on-problem (minutes) | The total time a student spent on each problem until the Skill Builder was completed. Specifically, time-on-problem was first computed for each problem solved by subtracting the timestamp when a student started to answer the problem from the timestamp when a student completed the problem (i.e., a correct answer to the problem is given by the student) then summed across problems to get the total time-on-problem. |
Total time-between-problems (minutes) | The total time students spent outside answering problems in ASSISTments before completing the Skill Builder. Specifically, time-between-problem was first computed by subtracting the timestamp when the student completed the prior problem from the timestamp when the student started the next problem then summed to get the total time-between-problems. |
Winsorized total time-on-problem (minutes) | The sum of time-on-problem values that were winsorized using a 10% cutoff. |
