FlipQuiz™ was created to provide educators with a quick way to create gameshow-style boards for test reviews in the classroom. Traditionally, these are created (tediously) using posterboard, chalkboards, or dry-erase markers on an overhead slide. The review questions are usually even written on a separate sheet of paper.
create interactive quizzes that are based on YouTube clips. Your quizzes can be about anything of your choosing. The structure of the quizzes has a viewer watch a short clip then answer a multiple choice question about the clip. Viewers know right away if they chose the correct answer or not.
"Socrative is a smart student response system that empowers teachers to engage their classrooms through a series of educational exercises and games via smartphones, laptops, and tablets."
EdPuzzle is a neat tool that I recently learned about from David Kapuler. EdPuzzle allows you to add your voice and questions to educational videos. On EdPuzzle you can search for educational videos from Khan Academy and Learn Zillion. Once you've found a video you can insert your own voice comments. You can also create a series of questions to go along with your chosen video. Questions are inserted along a timeline that matches the video. That means that your students don't have to wait until the end of a video in order to answer the questions. In that regard the EdPuzzle is similar to Blubbr.tv.
