During the past three decades, interest in computer-based instruction (CBI) has grown dramatically. Enhanced power, increased availability of peripheral devices, and developments in hypermedia have created extraordinary capabilities. At the same time, there have been significant, though largely unexploited, advances in research, theory, and practice. Collectively, these advances offer the potential to redefine learner-computer interaction. A rationale for, and description of, computer-mediated learning environments—multifaceted, integrated systems that promote learning through student-centered activities—are presented in this article.
