Kahoot! can be used in the classroom to assess student learning, review for tests, homework assignments, online based discussions, and ice breaker introductions to new subjects. As an assessment tool, Kahoot! can be used as the actual assessment itself. The assessment done in this fashion is always a favorite because the grading is already done for you. The results can be printed and gone over with each student in the event that they did not score very high. However, my students seem to like the old fashioned paper and pencil when completing actual assessments. A lot of the time I will use Kahoot! as a formative assessment. During a lesson, or as a bell-ringer, I will have the access code on the board with a 3-5 question quiz, and a time limit such as 5 minutes, to assess where the class is as a whole on comprehension of the lesson. I like doing this because it saves students the embarrassment of not knowing an answer when called on in class. I receive immediate feedback from the entire class and a percentage that got the questions right and wrong, If students got the questions wrong, I will know that I need to go back and reteach certain areas of the lesson. As a review for tests, I like to have students create their own kahoots, and play kahoot in class. Kahoot! allows for teams to be created and quizzed together, so on review days we will sometimes split the class into teams and make a competition out of the Kahoot review.
Students normally complain about having homework, but ever since I started giving them Kahoot homework they do not complain as much. Kahoot allows the teacher to open a quiz and then have a certain day/time for it to shut down (this eliminates the chance for students to say they forgot to do their homework and ask to turn it in later). I will create quizzes or discussions and require my students to take the quiz or make discussion posts as homework. I can easily see who did their homework and who did not. Students are more open to Kahoot homework because they can do it on their phones... they are going to be on their phones anyway!
The discussions are a great way to get students to engage in the material. I have also found that they learn more sometimes when they read what other students have said about a subject. I always make sure to have an online etiquette lesson beforehand to make sure that students know that they cannot post anything rude or vulgar on the discussion.
As an ice breaker for new subjects or lessons I will create a quiz as a pre-test just for a fun way to get students interested in the new materials. My students love using Kahoots and any chance we get to use it they are more than ready and willing to participate.
