Platforms letting teachers and students communicate and collaborate with each other are more popular than ever, and they also keep on getting better and better as time goes by. This startup is a definitive case in point.
On Piazzza, students and teachers can interact directly when they are online. The former can request course help from the latter in just a couple of clicks, in a way that is certainly faster and more accurate to these forums and newsgroups that we all have used at a time or other of our lives (and found extremely unfriendly and clunky).
A class can be created in a really simple way by instructors. Students can be added one by one, or be invited to join. The process is free and painless in both cases.
Piazzza is already being used on Stanford, MIT, Berkeley, Harvard and Princeton. If you are currently attending any of these Universities, chances are your class has already gone online, or is about to go online any minute. Check the site – you might be surprised.
