This chapter reviews some encouraging evidence that multimedia learning environments can promote constructivist learning that enables problem-solving. It begins with a description of a multimedia learning scenario, a cognitive theory of multimedia learning, and a set of design principles that lead to constructvist learning. Then, results from more than 40 studies are reviewed. In combination, these studies explore the conditions under which multimedia envionments promote problem-solving transfer of scientific and mathematical principles. The concluding section addresses the problem of how multimedia instructional messages can be designed to promote problem-solvig transfer.

The study examined how a computer-based visual metaphor can help students understand the addition and substraction of assigned number. The results indicated that visual metaphors need verbal guidance if they are to be used as an instructional tool to foster mathematical understanding.

How can we help students to understand scientific explanations of cause-and-effect systems, such as how lightning storms develop? One promising approach involves multimedia presentation of explanations in visual and verbal formats, such as presenting a computer-generated animation synchronised with narration or on-screen text. In a review of 4 studies conducted by the authors, they found evidence that presenting a verbal explanation of how a system works with an animation does not insure that students will understand the explanation unless research-based cognitive principles are applied to the design.

Two experiments exploed the integration of animated agents into multimedia enviornments in the context of Mayer's theory of multimedia learning. Experiment 1 was a 3 (agent properties; agent only, agent with gesture, no agent) X 3 (picture features: static picture, sudden onset, animation) design. Agent properties produced no significant effects. Both sudden onset and animation conditions facilitated performance relative to the static-picture condition. In Experiment 2, they explored the effects of printed text, spoken narration, and spoken narrarion with the printed text, in a mulitmedia environment that included an agent, to investigate effects of redundancy. The spoken-narration-only condition outperformed the other 2, with no differences between printed text and printed text with spoken narration.
