ChancePlus: A computer-based curriculum for probability and statistics

ChancePlus is a three-year project to research and develop effective methods for teaching introductory probability and statistics, especially at the high-school level. In this report, we summarize our activities during the second year of the project. Our efforts in this year were concentrated on developing and revising instructional units in probability and statistics and on the development of our statistical analysis program, DataScope. We also describe progress in our research of student understanding of probability and statistics and in the development of items to test for conceptual understanding.
