The *num_sessions_x *fields present the total number of sessions with the given time cutoff for a student in the learning environment of a course for a week in the term. The *total_time_seconds_x *fields show the amount of time in seconds a student spent in the learning environment. To find the total time spent in seconds, we add up all the durations of the sessions with the given time cutoff per student, course, and week in term. The *total_actions_x *fields present the number of actions of a student in the learning environment. The number of actions is calculated by counting the number of events associated with the sessions with the given time cutoff. The *avg_time_seconds_x *fields compute the average time in seconds a student spent in the learning environment. This is computed by dividing the total time spent in the learning environment (*total_time_seconds_x)* by the total number of sessions in the learning environment (*num_sessions_x)* for each student, course, and week in term. The *avg_actions_x *fields present the average number of actions in the learning environment. To compute this, we divide the total number of actions in the learning environment (*total_actions_x) *by the total number of sessions in the learning environment (*num_sessions_x) *for each student, course, and week in term.
