Unpopular opinion: interactive whiteboards in classrooms are overrated
Our school spent $12,000 on three Promethean boards last year and the projectors keep overheating mid-lesson, so now we're back to using dry-erase markers on the old boards - has anyone else found a fix for the ghost touches?

Our IT guy fixed our ghost touches by recalibrating with a wooden ruler, swear it actually worked somehow.

Ngl that sounds like pure witchcraft to me. How does a wooden ruler even recalibrate anything digital?
