Socrative is the favorite tool of Àngels Soriano (Spain)

One of my favorite tool is Socrative. This is an application available for android, windows 8 as well as via the web, where we can share with students questionnaires to evaluate content, content review, assess reading comprehension, to name a few.
The application has two profiles, the teacher who makes the test, and students. The quiz can contain multiple choice questions, verdaero or false, and open question.
Students can use both their mobile phones as any other device always from the student profile, after identifying with yourname, use the code of the room that the teacher has obrecido can go answering different questions, obtaining feedback if they are right or wrong.
From the profile of teachers we can decide if we have the names, or be anánimos questionnaires and receive email, the different responses of individual students.
Undoubtedly, socrativee is a great tool for students to offer more autonomy, this is a great tool to flipeddclass.
