I would think most if not all schools… a lot of the teachers I know like to prepare teaching material with slide shows for example nowadays which is done after hours on the computer, as well as writing using the interactive pen thingy during lessons, wasting less paper. I left school over 10 years ago too but we had them in secondary education. I would imagine it keeps younger ones engaged and interested during lessons, they’re also never too close to the board.
Totally normal
Most schools are this way now and to be honest my little boy is thriving, he's behind in where he should be but he's coming on leaps and bounds due to the help from having tablets and things on screens, it helps him understand so much better than just plain old pen and paper, it's colourful, interesting and a good way for the children of this generation to use tech for more than just watching YouTube videos and playing games
