Script Writing for E-Learning Narration

The Conversational Approach

Traditional Academic Writing: "In this module, we will examine the fundamental principles of object-oriented programming."

Voice-Optimized E-Learning Script: "Let's talk about object-oriented programming. Think of it as organizing your code into reusable building blocks. We'll cover three key concepts with real examples you can use right away."

Script Structure Best Practices

1. Hook (First 15-30 seconds)

Strong hook example: "What if I told you that 15 minutes of planning today could save you $50,000 in retirement? Let me show you exactly how."

2. Learning Objectives (30-60 seconds)

Clear template: "By the end of this lesson, you'll be able to: One - Create a pivot table in Excel in under 2 minutes. Two - Analyze sales data to identify top performers. Three - Build a dashboard your team can use. Let's dive in."

3. Content Delivery

Break into 3-7 minute segments with this pattern:

• Introduce concept (What)
• Explain why it matters (Why)
• Show how it works (How)
• Provide example (Example)
• Assign practice (Action)

4. Strategic Pauses

After questions: 2-3 seconds Before key points: 1 second After complex info: 1-2 seconds Between list items: 0.5 seconds

Pacing by Content Type:

• Introductory: 160-170 WPM
• Complex concepts: 140-150 WPM
• Examples: 155-165 WPM
• Review: 165-175 WPM
• Instructions: 145-155 WPM
