During lectures, it's hard for every student to let you know if they understand or if they're confused. Especially in large classes, many students are reluctant to express their confusion which limits both their learning and their enjoyment.
Understoodit addresses this issue by allowing students to anonymously, and in real-time, indicate if they understand or are confused. Understoodit runs on devices that you and your students already own: smartphones, tablets, netbooks and notebooks.
Why wait until evaluations at the end of the term to find out if your students were confused? With understoodit, you get feedback in real-time allowing you to make changes during your lecture to help students understand difficult topics.
