Kahoot is a free, web-based evaluation- and quiz tool. It lets you use quizzes in the classroom, and helps activate and engage students in discussions. Kahoot is suitable primarily for use within a monological form of teaching.
In the monologic form of teaching, Kahoot can, in the same manner as Socrative, be used by the teacher to evaluate students' understanding of the key concepts. For example, the teacher may draw up a series of test questions which the students must answer individually using their computer or smartphone, after which the teacher can see which students have responded correctly to the questions. As part of a formative evaluation, this use gives good opportunity to assess the teaching, so that all students reach the learning objectives.
Kahoot can also be used as a springboard for classroom discussions. The teacher can ask a question to the class, and provide students with a range of response options in Kahoot. The replies can then be displayed on the board, and form the offset for a discussion on a topic. The written starting point for the discussion provides a greater number of students to express their opinions, than what is the case in a normal show of hands.
Kahoot and Socrative have some similarities. One of the limitations of Kahoot seems to be, that the teacher does not have her own 'room'. Every activity you initiate gets a unique number, that students have to enter on their own device. On the other hand it is easy to share activities with others, and there are lots of inspiration from others in Kahoot, which is not the case in Socrative. Another possible weakness of Kahoot is, that question will not be shown on student devices – it only appears on the teacher's screen, which makes you dependent on a projector or similar.
