Raised lesson completion by 33% in one term
Cut revision cycle from quarterly to weekly
Aligned course design around measured drop-off, not surveys
“Our tutors had a theory about which lessons students dropped off at. Live funnels showed them the real one — and the fix raised completion by a third.”
Tidepool's course team revised lessons based on end-of-term surveys — feedback that arrived months after students had struggled. Drop-off points were guessed, not measured.
Tidepool instrumented lessons as event flows — lesson started, module complete, quiz passed — and watched them as live funnels. The team now revises the moment a step dips, with the exact modules at fault attached.
How Tidepool found the drop-off the surveys missed
Tidepool’s team had a strong hypothesis: students struggled with the week-four module on coastal currents. The data disagreed — and the data was right.
Funnels for lessons
Each lesson became a funnel: started, first section complete, mid-lesson checkpoint, final quiz passed. Week four was fine. The real cliff was a checkpoint quiz in week two that required a concept the lesson never introduced.
Revision in weeks, not terms
With drop-off points measured live, course design moved at the speed of a sprint rather than a semester. Fixes shipped mid-term and their effect was visible in the same funnel within days — an unheard-of feedback loop in education content.
The habit that stuck
Tidepool’s learning designers now start each revision session against the live funnels rather than the survey spreadsheet. The surveys still happen — they just confirm what the data already said, months earlier.
