Visualization technology can be used to graphically illustrate various concepts in computer science. We argue that such technology, no matter how well it is designed, is of little educational value unless it engages learners in an active learning activity. Drawing on a review of experimental studies of visualization effectiveness, we motivate this position(More)
We present JAWAA 2.0, a scripting language for creating animations easily over the web. JAWAA includes primitives, easy creation of data structures and operations on these structures, and an editor for easy creation of complex objects. We show how to use JAWAA in a range of computer science courses including CS 0, CS 1, CS 2 and advanced courses.(More)
We describe the instructional software JFLAP 4.0 and how it can be used to provide a hands-on formal languages and automata theory course. JFLAP 4.0 doubles the number of chapters worth of material from JFLAP 3.1, now covering topics from eleven of thirteen chapters for a semester course. JFLAP 4.0 has easier interactive approaches to previous topics and(More)
This paper describes the integration of the Alice 3D virtual worlds environment into a diverse set of subjects in middle school, including the development of tutorials, example worlds and lesson plans. In the summer of 2008 our experiences with middle school teachers included three-weeks of training in Alice and guidance in the development of lesson plans.(More)
This paper describes the implementation and evaluation of a program that uses <i>active recruiting</i> and <i>peer-led team learning</i> to try to increase the participation and success of women and minority students in undergraduate computer science. These strategies were applied at eight universities starting in the fall of 2004. There have been some(More)
After a 5year process, the Advanced Placement Computer Science (APCS) course and examinations have transi-tioned from Pascal to C++ beginning with the 199899 academic year. This lengthy process involved forming an APCS ad hoc committee comprised of high school teachers, university faculty and SIGCSE representatives. This committee convened in 1995-96 and(More)
