John Sweller (born 1946) is an Australian educational psychologist who is best known for formulating an influential theory of cognitive load. [1] He is currently (i.e., 2020) Professor Emeritus at the University of New South Wales .
According to work conducted in the field of instructional design and pedagogy, broadly, there are three types of cognitive load: 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 ...
The worked-example effect is a learning effect predicted by cognitive load theory. [1] [full citation needed] Specifically, it refers to improved learning observed when worked examples are used as part of instruction, compared to other instructional techniques such as problem-solving [2] [page needed] and discovery learning.
Chandler and Sweller found through empirical study that the integration of text and diagrams reduces cognitive load and facilitates learning. [5] They found that the split-attention effect is evident when learners are required to split their attention between different sources of information (e.g., text and diagrams).
"Cognitive load theory suggests that the free exploration of a highly complex environment may generate a heavy working memory load that is detrimental to learning". [attribution needed] [17] Beginning learners do not have the necessary skills to integrate the new information with information they have learned in the past. Sweller reported that ...

[3] [5] Cognitive load theory assumes that a learner's existing cognitive resources can influence the effectiveness of instructional techniques. [6] The goal of any learning task is to construct integrated mental representations of the relevant information, which requires considerable working memory resources.
