How I Use It
I use Socrative every day in my class (and sometimes even outside of class). Often, I program Socrative to allow students to work through specific problems in their course workbook - quizzing themselves as they go along. A few of my students this semester have even emailed me to say that they really enjoy the immediate feedback and that they are glad that we use Socrative regularly. The site even has options that allow students to work in teams, such as the Space Race.
If students wish to get some extra guided practice after class, I can open up a Socrative quiz (leaving it open for a day or two) and they can complete the quiz on their own time. Along with posting the correct answer after the students' submissions, the program can even display an explanation - should you choose to write one. I've included descriptions that explain why particular answers are right/wrong, and I find this really helps the students who are too shy to ask questions in class.
This program also helps lead into class discussions. After the class has completed the quiz, we can view how the class did (hiding the names of the students) and have a conversation about why one distractor may have been chosen. Students can also ask questions if they are still confused after reading the explanation.
Socrative is a great way to take attendance, receive immediate feedback on student thinking, have students practice a variety of math problems, do group work, and much more. In the college setting where every student brings a phone to class, it is really easy for students to log in and access the quizzes.
One critique I would have to offer would be that the program doesn't appear to be very math friendly. It would be nice if there was a LaTex option for writing questions or more mathematical symbols. Also, for free response questions, there may be different ways students enter a correct answer. For example, they may write: 6 feet, 6 ft, 6feet, or 6ft. If you want any of these answers to be seen as correct, you need to program them all as correct answers. On the students' end, after they complete the question, all of these answers will be displayed - possibly causing some confusion. It would be nice if Socrative had an option to select which answer would be displayed to the students.
