Designing Brain-Friendly Ultrasound Presentations

Effective presentations are crucial for disseminating knowledge and cultivating skilled learners. Cognitive load theory (CLT) offers a framework for optimizing instructional design by managing the mental effort required for learning. This article explores principles from CLT with practical suggestions to create brain-friendly presentations, focusing on intrinsic, extraneous, and germane cognitive loads. Intrinsic load can be managed through pretraining, organizing topics from simple to complex, and segmenting topics. Extraneous load should be minimized through coherence, signaling, redundancy, and spatial/temporal contiguity principles to eliminate unnecessary cognitive burden. Germane load can be enhanced by incorporating personalization, contextualization, relevance, interactive elements, and variability to promote deeper engagement and schema construction. This article emphasizes applying CLT principles to aid the reader in translating theory into practice.
