Instructional Message Design: Theory, Research, and Practice
Although theoretical in basis, Cognitive Load Theory (CLT) is pragmatic in nature. Its goal, as it relates to instructional message design, is to present information in a way that enables the learner to process it as efficiently as possible and add it to their brain as learned information. This process relies on the brain for memory, which is separated into two component parts – working memory and long-term memory. Both of these forms of memory are required to connect new information to information that is known – which are essential elements in the learning process. To do this, information that detracts from processing is discouraged, information that assists in processing is encouraged, and any complexity inherent to the learning is presented at a level that is appropriate (Chandler & Sweller, 1991; Sweller, 2008; Sweller, van Merrienboer, & Paas, 1998).
