People should care about this issue of lack on interaction because kids have been having troubles with school because of not being able to ask, being bored because its just constant note taking, and the fact tha most kids have a hard time at school because of not being able to show what they know other than tests. Kids should be able to interact and do projects more often because it allows the child to be free and to have a fun, more memorable time than just taking notes and watching documentaries. Also, this allows the child to actually pay attention during class and have more reasons to understand and remember the subject. It not only shows how much effort was put into it, it allows the child to chose and think more than a test or a worksheet and doesn't give them so much pressure.
