Explain cognitive load theory and its application to PT skills instruction.

• A. Minimizes extraneous load; manages intrinsic load through example, segmentation, and worked examples.
• B. Increases intrinsic load.
• C. Eliminates practice.
• D. Relies solely on lecture.

Answer: (A)

Cognitive load theory focuses on how working memory handles new information and how instructional design should prevent overloading it. In PT skills instruction, students must manage multiple steps, tactile cues, and real-time movement coordination, all while trying to form durable procedural knowledge. To support learning, design should minimize extraneous load—eliminate unnecessary details, distractions, and split attention, and use clear demonstrations with concise instructions that integrate information rather than scattering it across sources.

It should also manage intrinsic load by shaping task difficulty to the learner’s current level, which is where example, segmentation, and worked examples come into play. Demonstrations show the correct sequence, cue timing, and hand placements, letting learners study the flow without being overwhelmed. Segmentation breaks a complex skill into meaningful parts, so each component can be mastered before combining them. Worked examples provide a complete, correctly sequenced path with notes on common errors, reducing the mental effort required to figure out the steps from scratch. As learners gain proficiency, guidance can be faded and practice can become more varied to build robust schemas that support performance in real patient scenarios.

Increasing intrinsic load, eliminating practice, or relying solely on lecture would run counter to these principles, making it harder to acquire and transfer PT skills.
