Any researchers here?
I generated a report from Duolingo for Schools about the progress my students made during data collection for my research paper. However, I need to decide which numbers to use for my study. The report shows: days active, lessons, course progress and XP points. I also managed to copy/paste into a spreadsheet an activity of each student (telling me the days they used Duolingo, but not really possible to count the time as it only shows time stamps but not the actual duration). Can anyone tell me what Course Progress represents and can it regress in case a student e.g. didn't use Duolingo for a few days?
