Mark, let me give a few clarifications. The data visualization is for a high school, not BYU. The amount of time spent on gradeable activities is measured by the BrainHoney learning management system. It does not include time they might have spent away from the LMS or offline.

Yes, you are reading the chart correctly. Most students were engaged in at least some kind of gradeable activity each day (excluding holidays). They may not be submitting, but they are checking rubrics, grading sheets, etc.

This is incredibly nifty. What software did you use to generate the visualization? Is the source code available somewhere (and is it open source)?

Hi David,

I like your visualisation. Can I ask? How did you measure the ‘amount of time that student spent that day completing gradable activities’? Also, it appears that students might be expected to undertake ‘gradable activities’ almost every day. Is that usual at BYU or am I misreading the chart?

Thanks

Mark
