Most product design work rests on a set of assumptions that are so fundamental they rarely get examined: users chose to use your product, they can stop using it if it frustrates them, and their engagement or departure tells you something meaningful about the quality of your design. When you design for a captive user population, none of these assumptions hold.
SQOOL was deployed across 465 high schools in Île-de-France as part of a regional government initiative. 500,000 devices. Students received tablets they had not requested, running software they had not chosen, in a context (school) where they had limited ability to opt out of either. The engagement data we collected told us almost nothing useful. High usage of a feature could mean students found it valuable or that their teacher required it. Low usage could mean the feature was useless or that it simply was not part of the curriculum workflow that week.
