The mart_taskforce.level2_course_weekly_distribution_summary mart aggregates data about a course's performance and activities each week and describes the activity distribution. The schema for this mart largely mirrors that of mart_taskforce.level1_aggregated and mart_taskforce.level2_aggregated; however, this mart gives averages and standard deviations for each field. Questions about "what the average student" is doing in a course can be answered with this mart.

Field Structure and Subcategories

This level 2 table has many fields, so we’ve grouped them together in the following subcategories:

• Assignments

  • Submissions

  • Assignments

  • Missing Assignments

  • Late Submissions

  • Submission Time Buffer

    • Published Scores

• Discussions

  • Discussion Threads

  • Discussion Entries

• Learning Environment Activity

  • View days

  • Sessions

  • Tool Launches

  • File Views

Dependencies

The only dependency for this mart is the mart_taskforce.level1_aggregated. All calculations and fields are based on that mart, and there are no direct dependencies to the UDP itself. As long as the mart_taskforce.level1_aggregated is successfully created, this mart can also be created.

Assignment Weight Groupings

Many fields have names that include tiny, small, medium, large, and major. These classifications are based on the group_weight field in the ‘learner_activity_group’ entity. The cases are as follows:

• If the group_weight is null or equal to 0%, the submission is ‘unweighted’.

• If the group_weight is less than or equal to 2%, the submission is ‘tiny’.

• If the group_weight is greater than 2% and less than or equal to 5%, the submission is ‘small’.

• If the group_weight is greater than 5% and less than or equal to 10%, the submission is ‘medium’.

• If the group_weight is greater than 10% and less than or equal to 25%, the submission is ‘large’.

• If the group_weight is greater than 25%, the submission is ‘major’.

• If the group_weight is not null and greater than 0%, the submission is 'weighted'.

These assignment weight groupings are consistent with the groupings for the Level 1 mart.

Average and Standard Deviation Fields

The majority of the schema for mart_taskforce.level2_aggregated are averages and standard deviations based on the distribution of corresponding fields per-course, per-week in mart_taskforce.level1_aggregated. The corresponding table mart_taskforce.level2_aggregated applies these averages and standard deviations (per-course, per-week) for each student and produces z-scores accordingly.

These fields describe the distributions for the number of sessions, total time spent, total number of actions, average time spent, and average number of actions for all three time cutoffs for a student in a course for a given week in the term. The definitions of the base session, time, and action fields exist in the documentation for mart_taskforce.level1_aggregated.
