Studying pre-service teachers’ selection of representations in a technologically enhanced environment
Page: 1431
This paper reports the results of four groups of three pre-service teachers working on a task that had them investigate the fairness of dice. The teachers used an online collaborative environment to sample from six different dice and the environment provided them with various representations, which they used to support their arguments. All four groups preferred the frequency table over bar and pie charts representations. After working on the task, they evaluated the work of students on the same problem. They viewed students’ work that used other representations as not convincing regardless of the correctness of their solution and showed preference to the students only using one representation. Implications for pre-service teacher training in statistics and how to promote the use of multiple representations are discussed at the end.
