Short Answer is a web app for K-12 educators that engages students and improves learning outcomes using peer feedback. In a variety of gamified activities, students create responses, compare peer work, then reflect on activity results. Students get feedback on creative tasks in the moment instead of days apart, while teachers spend less time prepping lessons and giving feedback. Where the core K-12 offering described here is our primary focus today, Short Answer has a vision to become the peer feedback tool for teachers and learners everywhere by embedding our service in at-home study spaces, corporate training environments, and online courses.
