In Socrative, a teacher may create a free account where he can create different types of questions – multiple choice, short answer, and trueーfalse. The teacher can then invite students to the virtual room where student can send their answers via computer, tablet or smart phone. The answers can be viewed by the teacher on a computer and can be projected to an electronic whiteboard. Student answers on multiple choice questions can be auto-graded.
Socrative has pre-designed “exit tickets” where teachers can use to collect student thoughts . In addition, it also generates reports that can viewed using Microsoft Excel or Google Spreadsheets.
