In 2011, I spent an entire week after school trying to pair an ancient Samsung Galaxy tablet with a Chromecast plugged into the back of a brand-new six-foot interactive whiteboard at my school in Thailand.
I genuinely believed technology was about to revolutionise education. The dream was glorious in my head. I would roam the classroom with a tablet, photographing student work, annotating it live with a stylus and instantly projecting it onto the board like some futuristic teaching pioneer.
