“I am not a developer. I am a teacher with a lot of marking. Now the marking does itself and I get my Sundays back.”

“I am not a developer. I am a teacher with a lot of marking. Now the marking does itself and I get my Sundays back.”

Where it started

Lena teaches year 7 and 8 science to about 180 students. Marking weekly quizzes took most of her Sunday, and the results ended up in a spreadsheet nobody looked at twice.

What they built

Quizbox lets her write a quiz in a few minutes, marks the multiple choice answers on its own, and shows a chart per student so she can spot who’s stuck before the end of term. Students sign in with their school Google accounts.

What changed

She gets about six hours a week back. The charts also turned out to be useful at parents’ evening, which she had not planned for.
