As part of the Insights Index programme, and to collect real insights into teachers’ perspectives on the Wheels series, our dedicated research team has been gathering information from teachers around the world using Big Wheel, Ferris Wheel and Mimi’s Wheel. Between December 2020 and April 2022, the team conducted a series of surveys and in-depth interviews with Wheels users in Spain, Argentina, Turkey, Brazil, Mexico and China. Teachers were working in a variety of different institutions with the majority teaching more than one level of the course.
