Research on multimedia and related instructional technologies over many years has been characterized by inconsistent findings about their effects on learning. This is because of the myriad of contingent factors that have been shown to moderate multimedia effects. This article offers a model that is designed to integrate the main elements identified in the literature and also to describe their key inter-relationships. There are 12 elements in the model, each representing a theoretical construct, which can be operationalized as a variable. Learner style constitutes the independent variable, with learning as the dependent variable. The other elements are visual input, auditory input, learner control, attention, working memory, motivation, cognitive engagement, intelligence, reflection, and long-term storage, each of which is either an intervening or moderating variable or in some cases both. The elements in the model have causal or associative links with other elements. The proposed model is seen as useful in highlighting the complex nature of multimedia effects on learning and in fostering instructional design which addresses this complexity.

Considers how multimedia enhancements affect how much individuals learn from online news websites. Suggests that picture and audio are particularly powerful psychological cues. Finds that multimedia tends to hinder memory for story content and leads to negative evaluations of the site and its content, but improves memory for advertisements. Discusses theoretical and practical implications of these findings. (SC)
