Implement Aggregate Student Summary and Student Timeline

[philipmjohnson]

Please do work for this task in a branch called issue-231.

Aggregate Student Summary Statistics

In /radgrad@hawaii.edu/analytics/students/summary, select a time interval, and the system will generate aggregate summary statistics relative to the current student population.

Absolute numbers (and percentage) of students who did the following during the interval:

• logged into the system
• exhibited one of the six "behaviors" listed below.
• (later) how many "Engagements" occurred

Absolute numbers (and percentages) of students at each level by the end of the time interval. (if this is easy to do).

Individual Student Timeline

In /radgrad@hawaii.edu/analytics/students/<student>?start=2018-01-01&end=2018-05-02

Create a vertical timeline with dates and actions that occurred on that date for that student. Each entry in the timeline refers to a single session. The label is the date and the start time of the session. The first line indicates the number of minutes in the session. A session can contain one or more high-level "behaviors". The initial set of behaviors are:

1. "Change Outlook": This corresponds to a change in interests, career goals, or degree plan. It would be good to know the "before" and "after" state when any changes are made.

2. "Exploration": This corresponds to viewing entries in the Explorer. It would be good to track which entries are actually retrieved so we know which career goals, interests, etc. are most interesting. How long did they stay in each page of the Explorer before clicking away?

3. "Planning": This corresponds to work with the Degree Planner. It would be good to know when courses and/or opportunities are added and/or deleted. How long did they spend on planning before clicking away?

4. "Verification": We want to know when a student requests verification, and what opportunity was requested.

5. "Reviewing": When a student submits a review of a course. How long did they spend on this?

6. "Mentorship": When a student visits the MentorSpace page, and how long they stayed there before clicking away.

7. "Level Up": When a student achieves a new level.

8. "Complete Plan Achieved": The moment when a student has first created a degree plan that, if executed to completion, will result in at least 100 points in all three ICE categories.

In addition, this timeline should (eventually) record when a user received an "Engagement" (such as an email).

Augment user interaction types

Log the following user interactions:

• Add review
• Change of level
• Request verification
