Learning Trajectories visualization wiki

Status: Active

Goals (ordered by priority)

1. Implement learner trajectory dashboard - production level visualization and layouts; includes main visualization (a), and supplementary visualizations of student performance/proficiency data (b)

   • Learner Trajectory Network basemap
     • Linear network layout (highest priority) - visualize individual students interactions and transitions between course modules;
     • Temporal-coordinate layout (stretch) - visualize student with additional temporal dimension; comparison of multiple students.
     • Force atlas layout
   • Supplementary student/cohort visualizations
     • Learner Performance and Participation Heatmap
     • Statistical visualizations of student activity and time (individual to group comparison) (e.g. box-plots)
     • Track proficiency trajectory across assessment instruments (e.g. line graphs)
     • Visualization of cohort activities (e.g. scatter plots)

2. Create an dynamic learner trajectory network - A network visualization of individual student's interactions with and transitions between course modules, which allows a user to explore data and animate a student's activity in LMS over time.

3. Evolving Architecture - visualization architecture should evolve to add new production visualizations as research questions and/or data sets emerge;

   • Works with existing e-learning technology standards - LTI and Caliper standards (see documentation links)
   • Supplementary data sets on module learning objective and cognitive load.

4. Provide tools for data extractions - data filters parameters should create subsets of data for a student that may be extracted for re-use in analysis or learning model.
