query: What is the worked-example effect and how is it related to cognitive load theory?
answer: The worked-example effect is a learning effect predicted by cognitive load theory.  It refers to the improved learning observed when worked examples (step-by-step demonstrations of problem-solving) are used in instruction, compared to other methods. Worked examples reduce cognitive load during skill acquisition, making learning more efficient.
