How long do users spend on Moodle (or more generally e-Learning) is another common question worth some initial exploration as part of my broader goal towards the notion of an engagement metric. This article discusses an approach into defining and obtaining insights from the idea of a session length for learning. This is mostly a data wrangling exercise to approximate the duration from event logs that will tell us that while all events are born equal, some are more equal than others. The algorithm should prove useful when I progress to course breakdowns in identifying particularly dedicated or struggling students who are investing larger amounts of time online, or those at-risk who aren’t spending enough. These questions are something I will return later in a future post as part of the project.
This works on the same data as last week’s look at some basic distribution analysis which contains extraction SQL.
