iSLCollective is a “free web-based tool that allows teachers to create interactive video quizzes around YouTube and Vimeo videos. This is how it works: First, teachers choose videos from YouTube or Vimeo. Next they write questions that will pop up throughout the video. They can also add a lesson plan, vocabulary list, and discussion questions.
