Why Sketching May Aid Learning From Science Texts: Contrasting Sketching With Written Explanations.

Area of Science:

• Cognitive Psychology
• Educational Psychology
• Learning Sciences

Background:

• Constructive learning strategies, like self-explanation, enhance information processing.
• The role of visual representation in learning is an area of ongoing research.
• Sketching is a potential constructive strategy with unique visual benefits.

Purpose of the Study:

• To compare the learning benefits of sketching versus self-explanation.
• To investigate whether sketching offers advantages beyond general constructive processes.
• To determine if the quality of strategy implementation affects learning outcomes.

Main Methods:

• Seventy-three seventh-graders were taught either sketching or self-explanation techniques.
• Students studied an expository text on the greenhouse effect using their assigned strategy.
• Learning was assessed via recall and transfer questions, with strategy quality analyzed.

Main Results:

• Overall performance differences between sketching and self-explanation were marginal.
• Students who implemented strategies with higher quality showed significant differences, with sketching outperforming self-explanation.
• Higher quality sketching strongly correlated with better learning outcomes.

Conclusions:

• Sketching provides unique benefits for learning that extend beyond those of written self-explanation.
• The effectiveness of sketching is dependent on the quality of its implementation.
• Visual representation through sketching can enhance learning when deployed effectively.
