Uri Wilensky uses StarLogo towards a different goal: to help learners develop their intuitive conceptions of probabilistic ideas. In Wilensky's chapter, "Learning Probability through Paradox and Programming," he presents a case study of a learner who uses programming to help resolve a probability paradox, and in the process develops stronger intuitions about randomness and distribution-and the connections between them. Wilensky's study illustrates that the primary obstacles to learning probability are conceptual and epistemological, and it shows how programming can play a powerful role in learning mathematics by making hidden assumptions explicit and concrete.
