Have you ever been confused in class but just too nervous to ask a question? Well Understoodit, a startup founded by Liam Kaufman is hoping to remedy that problem. Understoodit will allow students to express their confusion during the lecture. The catch is that the teacher won’t actually know which student is confused. In theory this will help students to become more comfortable asking questions. Unfortuantely, Understoodit is only available via invitation, however, they are hoping to publicly launch the product by the end of the summer. [Source: TC]
