I came across Quizlet last week and found it to be a very useful tool for online instruction. For instance, after getting your students to go through a certain collection of online materials, you can create interactive quizzes as formative assessments to scaffold their learning. Now, if you are doing a face-to-face class, Quizlet would not be that useful since it works best in a self-paced environment.
I was introduced to Kahoot! this week by one of my classmate and i think it fills the gap that Quizlet is not able to in a face-to-face setting. The main reason why Kahoot! works so well in a face-to-face setting is because it allows you to inject a sense of competition into your quiz in the following ways:
Set countdown for the questions
The use of symbols, colours and the mirroring position of them on the mobile device allows students to respond quickly, adding an exciting element of speed to the quiz.
Students get instant feedback if they answered the question correctly and how the other did with a visual graph.
After attempting each question, students get informed of their position relative to the rest! Serves as a positive and negative reinforcement to sustain motivation.
The final scoreboard that will get students screaming and moaning all at the same time!
