Ray tracing is a computer graphics technique used to produce realistic visuals by physically simulating the behavior of light. Although this technique can be described straightforwardly, fully comprehending it might be challenging. It is typically taught in the classroom using the 2-D formats, such as paper or a blackboard. We propose using…

Based on a three-semester design research study, this paper argues the need to redesign online learning environments to better support the representation and sharing of factual, procedural, and conceptual knowledge in order for students to develop their design capabilities. A web-conferencing environment is redesigned so that the modalities…

The diversity and interdisciplinarity of computer science and the multiplicity of its uses in other sciences make it hard to define computer science and to prescribe how computer science should be carried out. The diversity of computer science also causes friction between computer scientists from different branches. Computer science curricula, as…

This paper presents the implications of an ongoing project on the design and development of multimedia instructional material for teaching and learning computer science topics at both graduate and undergraduate levels. Important pedagogical requirements that CAI software should satisfy include: (1) animation of the changes in tree topologies; (2)…

Discussion of graduate programs in educational computing highlights six models of educational computing programs: (1) the computer science model, which stresses programing; (2) the educational psychology model; (3) the programed instruction model; (4) the instructional design model; (5) the information center model; and (6) the audiovisual…

This paper presents results of research on an intensive online graduate level course in Web-based instruction (WBI) delivered via the same medium. The classes, offered concurrently at the University of Memphis and at Georgia State University, provide students with experiences centered around three areas: being a student in an online environment;…
