Can anyone explain how smartboards work, who creates the software, etc. My kid is in pre-k and he likes smart boards but i suspect that’s because of very limited screen time at home. Are smartbords detrimental in any way having that they’re not excessively used? I wish I could see them myself but am not allowed in the school.
