Playposit is a interactive web-based video platform that allows educators (and students) to provide formative assessment both inside and outside the classroom. Teachers (and students) are able to embed quiz-type questions into their own videos or videos found on Youtube, Vimeo, Khan Academy and other popular video platforms. Data can then be analyzed on the individual or group level, providing powerful insight into educational trends in the classroom.
