Abstract
A learning management system (LMS) data portal contains data collected as a byproduct of the running of the LMS. A data dictionary related to that data portal contains both critical information about the data and a list of terms and definitions describing the data contents. The modern LMS studied here has multiple channels for data capture and analytics: (1) the front-facing LMS (at both the instructor level and the admin level), (2) the reports feature (for system administrators), and (3) the data portal (for system administrators). This chapter describes some ways to understand data possibilities through the examination of an LMS data portal data dictionary and light LMS data exploration.
