Student Activity Score
The student activity score marts are based on Indiana University's Student Activity Score, developed by Matthew Rust, Joshua Quick, and Benjamin Motz. The student activity score is a metric based on student activity in the LMS, and can be used to predict the final outcomes and persistence of students. A study exploring the predictive ability of this metric, coauthored by Matthew Rust and Benjamin Motz, can be found here.
The student activity score marts include both student_activity_score and student_activity_score_rolling marts. These marts include the same metrics, but differ with regards to the time window in scope. The student_activity_score marts define the metrics for every week in a course, Sunday to Saturday. The student_activity_score_rolling marts define the metrics for a 7-day rolling window for each day in the course. This means that for a given week in a course, the student_activity_score mart will define a single record for each student, while student_activity_score_rolling will define 7 records for each student, one for each day in the week.
