Fields
last_activity
This field is derived from the UDP event store. Per person, per course we pull the most recent event timestamp, regardless of event type. This signifies the latest activity of any type for a student in a course.
last_navigation_activity
This field is derived from the UDP event store. Per person, per course we pull the most recent event timestamp where the event type = ‘NavigationEvent’
last_media_activity
This field is derived from the UDP event store. Per person, per course we pull the most recent event timestamp where the event type = ‘MediaEvent’
last_grade_activity
This field is derived from the UDP event store. Per person, per course we pull the most recent event timestamp where the event type = ‘GradeEvent’
last_assessment_activity
This field is derived from the UDP event store. Per person, per course we pull the most recent event timestamp where the event type = ‘AssessmentEvent’
last_assignment_activity
This field is derived from the UDP event store. Per person, per course we pull the most recent event timestamp where the event type = ‘AssignableEvent’
num_events
Per person, per course, this field gives the total number of events that have occurred to date.
num_navigation_events
Per person, per course, this field gives the total number of events that have occurred to date where the event type = ‘NavigationEvent’
num_media_events
Per person, per course, this field gives the total number of events that have occurred to date where the event type = ‘MediaEvent’
num_grade_events
Per person, per course, this field gives the total number of events that have occurred to date where the event type = ‘GradeEvent’
num_assessment_events

Tableau Template Workbook
As a starting point for visualization for this data mart, Unizin has created a Tableau template workbook available for download here:
Connecting to Data
The default data connection in the workbook is to Unizin's synthetic data. After downloading the workbook, the first step will be to transfer the connection to your own production UDP data. Here is a guide document to help with this process; Tableau also has a published doc for replacing data sources. For any issues connecting to source data, please contact [email protected].
Tableau Dashboard Filters
The following fields are used as filters in the Tableau Workbook:
Academic Organization - The academic department name
Instructor Display - The list of names of the course's instructors.
Course Offering Title - The title of the course offering.
UDP Course Offering ID - The UDP ID of the course offering.
Academic Term - The academic term of the course; the default selection is the current term.
These filters are in scope for all visuals in the dashboard.
Tableau Visualizations
These metric cards highlights key student activity metrics. They include the total number of enrolled, active, and inactive students. The metric cards also define the average number of days and hours students spent in the course, as well as the average number of inactive days. These metrics help assess overall student engagement in courses across the institution.
This heatmap shows when students are most active throughout the week, with color intensity representing the number of distinct last activity records. Darker shades indicate higher engagement levels, helping to pinpoint peak hours of student activity and identify times with lower participation.
The days percent activity chart shows the percentage of total last activity recorded on each day of the week. This helps identify which days students are most and least active, offering a clear view of weekly engagement trends.
The Last Activity at Different Times chart displays the number of distinct last activity events across different hours of the day. This helps identifying peak times of student engagement as well as hours with minimal activity, supporting better planning for course interactions and support availability.
Most common day/hour for the last activity table lists the most frequent combinations of day and hour when students were last active. This makes it easy to spot the most popular times for student engagement
NOTE: For production use, please make sure it's appropriate for users to have visibility into student names. If names are too sensitive, please drop this column from the visual before sharing to users.
Last Activity table provides detailed student-level data, including academic organization display, course offering ID, student name and ID, last activity timestamp, total number of activity events, and the number of assignment-related events. If offers a comprehensive view of individual engagement and helps track student participation in course activities.
