my old School got a glass Tunnel for 20 meters one year after i left, mY current School has so little money we had 3 hours a day, for 2 weeks because one teacher is sick. Nonetheless we still have 1 of these unusable "smartboards" for every 1.5 rooms or so. This is Germany btw
My guess is they never ran power drops for them, or they never taught teachers how to use them. Happens a lot - "hey we got cool new tech, but the grant is hyper-specific that it has to be spent on new tech, NOT training for that new tech."
