What CLT is

Cognitive load theory (CLT) is an instructional theory based on our knowledge of human cognitive architecture. That architecture assumes a limited capacity, limited duration working memory used to process novel information and a large long-term memory used to store knowledge that has been acquired for subsequent use. Knowledge stored in long-term memory is assumed to eliminate the capacity and duration limits of working memory. The theory has been used to generate a wide range of instructional procedures. The aim of each instructional procedure is to optimize working memory load to facilitate the acquisition of knowledge in long-term memory. The comparative effectiveness of all instructional procedures based on the theory has been tested using replicated, randomized, controlled trials.
