Towards a Cognitive Theory of Multimedia Assessment (CTMMA)

Much is known about assessment in all its forms and the corpus of theory, and knowledge is growing daily. In a similar vein, the use of multimedia for learning also has a sound basis in research and theory, such as the cognitive load theory(CLT; Sweller, Van Merrienboer, & Paas, (1998). Educational Psychological Review, 10, 251–296), human information processing (e.g., Atkinson & Shiffrin (1968). Human memory: A proposed system and its control processes. In K. W. Spence & J. T. Spence (Eds.), The psychology of learning and motivation: Advances in research and theory (Vol. 2, pp. 89–192). New York: Academic Press; Miller (1956). Psychological Review, 63, 81–97; Paivio (1986) Mental representations: A dual coding approach. New York: Oxford University Press), and praxis in the form of evidence-informed design principles often based on the cognitive theory of multimedia learning (CTMML; Mayer (2005b). Cognitive theory of multimedia learning. In R. Mayer (Ed.), The Cambridge handbook of multimedia learning (pp. 31–48). New York: Cambridge University Press). However, the combination of the two lacks both theoretical underpinnings and practical design principles. Multimedia assessment (MMA) is, at best, either a translation of paper-based assessment and assessment principles to the computer screen or an attempt to make use of the theory and principles underlying multimedia learning (i.e., CTMML). And this is the problem. In the first place, MMA needs, just as multimedia learning (MML), its own theory and principles. Just as MML was not simply the translation of paper-based learning to the computer screen, MMA requires its own place. In the second place, the application of CTMML and its principles to assessment leads to problems. The CTMML is based upon the idea that learning should be facilitated by the proper use of CTMML principles and its underlying theories (CLT, human information processing). In cognitive load terms, germane load is increased, while extraneous load is avoided so as to facilitate effective and efficient learning. But the goal of assessment is not learner facilitation, but rather separating the wheat from the chaff. Those who do not possess the knowledge and skills need to not be able to answer the question, while those who do have the knowledge and skills need to answer correctly. This may mean that certain forms of extraneous load need to be increased, while germane load needs to be minimized. This chapter will kick off the road to a cognitive theory of multimedia assessment (CTMMA).
