Abstract
This study considers students’ predictions and explanations for outcomes when a normal
six-sided die is tossed 60 times. Changes are monitored after lessons on chance and data
and/or after two years. The study is motivated by two approaches to probability advocated
in the mathematics curriculum: one stressing expectation based on theory and the other
acknowledging variation during experiments. The outcomes are discussed in light of other
research and the dilemmas created for students by these two approaches to probability.
