Kahoot is a popular online quiz tool which many Irish teachers use for both formative and summative assessment. In this Business Studies lesson with a third year group mixed ability group, Claire Fitzgerald from Malahide Community School demonstrates how Kahoot can be used to support active learning and collaborative revision. She divides the class into groups and each group is given a topic to revise using tablets, textbooks and other resources. Each group then creates an online quiz using Kahoot to demonstrate their knowledge of the topic and test the knowledge of the other groups. Topics include trading account, profit and loss account, balance sheet, business documents and delivery systems. Active learning and peer assessment is evident as groups create quizzes to test each other out, while developing their research and communication skills. Claire also discusses how the use of technology supports differentiation and students taking ownership of their own learning.
