This chapter examines the cognitive demands of student-centered learning from, and with, Web-based multimedia. In contrast to externally-structured directed learning, during the student-centered learning, the individual assumes responsibility for determining learning goals, monitoring progress toward meeting goals, adjusting or adapting approaches as warranted, and determining when individual goals have been adequately addressed. These tasks can be particularly challenging in learning from the World Wide Web, where billions of resources address a variety of needs. The individual, in effect, must identify which tools and resources are available and appropriate, how to assemble them, and how to manage the process to support unique learning goals. We briefly analyze the applicability of current cognitive principles to learning from Web-based multimedia, review and critically analyze research and practice specific to student-centered learning from Web-based multimedia, and describe implications for research.
Several time-tested cognitive principles are applicable to both face-to-face and print-based learning environments. Indeed, the research summarized throughout this text supports several principles and constructs relevant to multimedia. However, much of this research is rooted in objectivist epistemology, where the individual selects, organizes, and integrates knowledge in an effort to acquire and demonstrate externally prescribed, canonical meaning. While the effectiveness of didactic, directed methods have been demonstrated using multimedia (see, for example, Azevedo, Moss, Greene, Winters, & Cromley, 2008; Gerjets, Scheiter, & Schuh, 2008), significant growth has been evident in user-centered, Web-based multimedia applications that are individually rather than externally directed and managed.
This chapter focuses on student-centered learning in Web-based multimedia environments wherein the individual assumes primacy in determining goals, selecting or devising approaches to address these goals, and responsibility for interpreting and constructing unique meaning. We examine the applicability of research related to Web-based multimedia and address both similarities and differences in cognitive demands between ill-structured and externally-structured multimedia learning environments. The purposes of the chapter are to briefly review selected principles of human cognition that are applicable to Web-based multimedia, to review cognitive perspectives, research, and practice specific to student-centered learning from Web-based multimedia, and to describe implications for research, theory, and practice.
