I can see where you are coming from, they do seem as though they could be educational, don't they? I am guessing that they were meant to be pets, pets take responsibility, I don't think Bandai walked out and said "Lets make a toy that teaches responsibility and call it Tamagotchi!" no? I do believe it does though. Last year, I figured out how to take care of six Tamagotchis, get them to, basically, all be a masktchi, and get 3rd honors in school. They barley distracted me, but for others, it's different.
Some kids think they are living breathing animals that need to be taken care of, others, not so much. So what I am getting at is basically, yes and no. They obviously weren't meant to be educational, but they are. Bandai did a good job, lets leave it at that, eh?
I can see my science teacher letting us use Tamagotchi's for a project. I own enough to lend him a few of mine, plus I am sure my parents would chip in, mainly because, my dad likes to see if they are dead yet (He is so nice, is he not?) and what character you get. My mom, she is different, but still. I was thinking about asking him too. He could talk to all of our teachers, get us passes that allow us to use our Tamagotchi's during school, and after, lets say, a week, report on how they are doing back to him. It is fun (Which he is) and educational. I have a million reasons why we should do this in school, and when I get off break, I will ask him about it. I will label my Tamagotchi's she lend them to him, not that I couldn't tell which ones were mine.
Getting back on topic, I say yes and no. Not much else to say. ;D
