# Cognitive Load Analyser

## What This Skill Does

Evaluates a learning task, instruction set, or resource for cognitive load across three dimensions: intrinsic load (inherent complexity of the content), extraneous load (unnecessary difficulty caused by poor design), and germane load (productive cognitive effort directed at schema building). Produces a specific diagnosis of where load is excessive and concrete modification suggestions. AI is specifically valuable here because cognitive load analysis requires simultaneously evaluating content complexity, instructional design quality, and learner expertise level — a skill that typically requires training in instructional design that most teachers lack.

## Evidence Foundation

Sweller (1988, 1994) established Cognitive Load Theory (CLT) as a framework for understanding why some instructional designs fail: human working memory can hold approximately 4-7 elements simultaneously, and learning fails when the total cognitive load exceeds working memory capacity. Sweller distinguishes intrinsic load (determined by element interactivity — how many elements must be processed simultaneously), extraneous load (caused by poor instructional design), and germane load (productive effort directed at building schemas). Paas & van Merriënboer (1994) operationalised CLT for instructional design, demonstrating that reducing extraneous l
