Probability Explorer was initially designed, developed, and researched as part of the author's doctoral work at the University of Virginia in 1998-2000. Since that time, the author has conducted several research studies while at NC State University and the software has emerged in an iterative research and development cycle. The software environment has grown and changed based on field testing and research results from careful analysis of students' interactions with the software tools and development of students' probabilistic reasoning.
