Cognitive Load Theory by John SwellerOver the last 25 years, cognitive load theory has become one of the worlds leading theories of instructional design. It is heavily researched by many educational and psychological researchers and is familiar to most practicing instructional designers, especially designers using computer and related technologies.
The theory can be divided into two aspects that closely inter-relate and influence each other: human cognitive architecture and the instructional designs and prescriptions that flow from that architecture. The cognitive architecture is based on biological evolution. The resulting description of human cognitive architecture is novel and accordingly, the instructional designs that flow from the architecture also are novel. All instructional procedures are routinely tested using randomized, controlled experiments.
Roughly 1/3 of the book will be devoted to cognitive architecture and its evolutionary base with 2/3 devoted to the instructional implications that follow, including technology-based instruction. Researchers, teachers and instructional designers need the book because of the explosion of interest in cognitive load theory over the last few years. The theory is represented in countless journal articles but a detailed, modern overview presenting the theory and its implications in one location is not available.
Cognitive load theory: 3 different types of cognitive load
In cognitive psychology , cognitive load refers to the used amount of working memory resources. Cognitive load theory differentiates cognitive load into three types: intrinsic, extraneous, and germane. Intrinsic cognitive load is the effort associated with a specific topic, extraneous cognitive load refers to the way information or tasks are presented to a learner, and germane cognitive load refers to the work put into creating a permanent store of knowledge, or a schema. Cognitive load theory was developed in the late s out of a study of problem solving by John Sweller. Much later, other researchers developed a way to measure perceived mental effort which is indicative of cognitive load.

Permalink Print. Cognitive load is typically increased when unnecessary demands are imposed on a learner, making the task of processing information overly complex. Such demands include the unnecessary distractions of a classroom and inadequate methods used by teachers to educate students about a subject. When cognitive load is managed well, students are able to learn new skills easier than when high cognitive load interferes with the creation of new memories. By understanding the principles behind cognitive load theory, teachers can optimize the way they present novel ideas to students to make them easier for their audience to understand. Cognitive load theory was first outlined in by John Sweller, an educational psychologist at the University of New South Wales, Australia. Sweller built on the working memory model of memory which proposed that long-term memories develop when auditory and visual information is processed or rehearsed to a greater degree than other everyday observations Baddeley and Hitch,
