Benefits of Writing an Explanation During Pauses in Multimedia Lessons.

Area of Science:

• Cognitive Psychology
• Educational Technology
• Learning Sciences

Background:

• Generative learning theory emphasizes active learner engagement (selecting, organizing, integrating) for deeper learning.
• Online multimedia lessons often involve passive consumption, potentially limiting deep learning.
• Investigating active learning strategies within digital educational environments is crucial.

Purpose of the Study:

• To determine if generative learning activities, specifically generating explanations, enhance learning from online multimedia lessons.
• To compare the effectiveness of different generative explanation prompts against passive review and no-activity conditions.
• To test the applicability of generative learning theory in digital learning contexts.

Main Methods:

• Three experiments were conducted with college students learning about greenhouse gases via a 4-part online multimedia lesson.
• Learners engaged in various activities after each lesson part: generating explanations, focused explanations, rewriting explanations, reading explanations, or no activity.
• Learning outcomes were assessed using immediate and delayed posttests.

Main Results:

• Students who generated explanations (write-an-explanation, write-a-focused-explanation, rewrite-an-explanation) showed significantly better performance on delayed posttests compared to the no-activity group.
• No significant differences were observed on immediate posttests across groups.
• Active generative learning strategies appear to foster long-term knowledge consolidation.

Conclusions:

• Generative learning activities, particularly explanation generation, are effective for improving long-term retention in online multimedia learning.
• Prompting active learning strategies can enhance the effectiveness of digital educational content.
• Findings support generative learning theory and inform the design of more engaging online learning experiences.
