We decided to make this because we've all been in lectures of 300 people where almost all of the students have no idea what's going on but the professor doesn't slow down anyway. We decided that there should be a real time feedback solution where the professor could measure the amount of understanding his students have and students could tell the professor when they are confused
How it works
Mobile Web App with 2 aspects. Students make comments and hit 3 buttons explaining whether or not they're confused, neutral, or understanding material. Professor sees information in real time and adjusts lecture accordingly.
