Just tested My Studyio because a tweet from @GrahamStanley and @NikPeachey. What a great surprise as tomorrow I´ll be presenting about cool tools for the classroom for a group of Brazilian educators. I liked My Studyio because it´s user-friendly and very easy to register. You can have multiple choice questions with an attractive layout adding images, youtube videos and texts. The final result is an embeddable quiz that you can put anywhere on the Net, or even send to students.
Also, I can picture my students creating quizzes and posting them to the others to take the quizzes. By doing that, they will learn a new skill and practice the language structures they are focusing on. Oh, by the way, the fact that you can embed the quiz in Orkut is a plus for Brazilian students who are totally hooked to this social network.
