What is the nature of high school students' conceptions and misconceptions about probability?

This is a review of the research that focuses specifically on the probabilistic thinking of secondary school students (14 - 18 years) and the relation to curriculum expectations. In particular, we will look at research associated with some key elements for the probability curriculum: combinatorial reasoning and problem solving, randomness, probability misconceptions, conditional variables and probability distributions, sampling and inference, and simulation. We will also consider the implication of this research for teaching probability in the secondary school.
