Lecture Designer

Note: If you prefer local Quarto reveal.js slides, reference guides are available in the quarto/ directory, but Google Slides is the recommended workflow.

Core Principles

1. Learning outcomes first: Define what students should be able to do by the end, then design backward from there.

2. Narrative over coverage: A lecture is a story, not a chapter recitation. Use the ABT (And, But, Therefore) structure to create cognitive tension and resolution.

3. Cognitive load management: Apply Sweller's Cognitive Load Theory—minimize extraneous load, manage intrinsic load through chunking, maximize germane load through active processing.

4. Active learning is required: Passive listening fails. Design deliberate state changes every 12-18 minutes using polls, peer instruction, and activities.

5. Visual simplicity: Slides support the speaker, not replace them. Apply Mayer's multimedia principles—coherence, signaling, segmenting, redundancy avoidance.

6. Pause for instructor input: Stop between phases to get the instructor's substantive expertise and preferences.

Inputs

The instructor provides:

• Chapter/reading material: The textbook chapter or content to be taught
• Instructor notes (optional): What they want to emphasize, known student struggles, war stories
• Context: Course level, class size, time available, prior knowledge assumed

Outputs

The skill produces:

• Lecture plan: Learning outcomes, chunk map, temporal timeline
• Slide deck: Google Slides presentation with speaker notes (created via MCP)
• Activity set: Polls, ConcepTests, and active learning activities
• Instructor guide: Delivery notes, backup plans, post-class follow-up

Analysis Phases

Phase 0: Context & Learning Outcomes

Goal: Understand the teaching context and define measurable learning outcomes.

Process:

• Clarify course level, class size, time constraints, and student background
• Review the chapter/reading material
• Review instructor notes and emphases
• Define 3-5 measurable learning outcomes (what students should be able to DO)
• Identify evidence: how will we know they learned it?

Output: Context memo with learning outcomes and evidence plan.

Pause: Confirm learning outcomes with instructor before proceeding.

Phase 1: Content Audit & Narrative Design

Goal: Transform chapter content into a narrative arc.

Process:

• Content Audit: Categorize chapter content as:
  • Essential: Core concepts requiring expert modeling (80% of lecture time)
  • Helpful: Supporting examples, interesting details (cut or make optional)
  • Decorative: Tangential material (eliminate)
• Narrative Arc (ABT):
  • And (Setup): Establish context, what we know
  • But (Conflict): The paradox, gap, or puzzle
  • Therefore (Resolution): The new understanding
• The Hook: Design an opening mystery/problem that grabs attention in 60 seconds
• Chunk Map: Break into 3-4 chunks of ~15 minutes each

Output: Content audit, narrative arc document, and chunk map.

Pause: Review narrative structure with instructor.

Phase 2: Active Learning Design

Goal: Design activities that reset attention and promote deep processing.

Process:

• Poll Set Design (for 75-minute lecture):
  • Poll 1 (min 0-3): Prediction/baseline misconception
  • Poll 2 (min ~20): ConcepTest on Chunk 1
  • Poll 3 (min ~40): ConcepTest on Chunk 2 (hardest material)
  • Poll 4 (min ~55): Transfer/application to new case
  • Poll 5 (min ~72): Muddiest point/confidence check
• ConcepTest Design:
  • Stem describes a situation; answers are mechanisms, not vocabulary
  • Distractors are the top 3 wrong mental models
  • Target 30-70% correct for optimal peer discussion
• Peer Instruction Protocol: Plan Think-Pair-Share moments
• State Changes: Non-digital breaks (sketch, discuss, stretch)

Output: Complete activity set with polls, ConcepTests, and protocols.

Pause: Review activities with instructor. Adjust for their style.

Phase 3: Slide Development

Goal: Create visually effective slides directly in Google Slides via the Google Docs MCP.

Process:

• Create Presentation: Use createPresentation to create a new Google Slides deck
• Apply Multimedia Principles:
  • Coherence: Cut decorative clutter
  • Signaling: Highlight what matters (arrows, bolding, progressive reveal)
  • Segmenting: One concept per slide
  • Redundancy: Don't put full sentences on screen while speaking them
• Accessibility:
  • Minimum 24pt body text, 32pt+ headings
  • High contrast (dark on light or light on dark)
  • Describe all visuals verbally
• Speaker Notes: Add delivery cues, timing, and transitions to each slide
• Image Suggestions: Proactively search for relevant images on Unsplash/Pexels using WebSearch (e.g., site:unsplash.com [concept]) and provide curated links for the instructor to add

Output: Google Slides presentation URL with speaker notes, plus image suggestions document.

Pause: Review slides with instructor.

Phase 4: Review & Refinement

Goal: Ensure the lecture is deliverable and has backup plans.

Process:

• Temporal Check: Verify the timing adds up to available class time
• Cognitive Load Audit: Check for overloaded slides or rushed segments
• Failure Modes: Plan backups (WiFi down → show of hands, running late → what to cut)
• Instructor Guide: Compile delivery notes, timing cues, and post-class follow-up
• Finalize Materials: Ensure all files are organized and ready

Output: Final lecture package with instructor guide.

Key Principles from Research

The Numbers That Matter:

• 18 minutes: Maximum before cognitive overload (soft breaks every 10-15 min)
• 75 words: More than this per slide = it's a document
• 6 words: Ideal target per slide (Godin/Reynolds)
• 3 seconds: Audience must grasp slide content this fast
• Rule of 3: Organize around 3 key messages
• 65%: Top TED talks are 65% stories, 25% data, 10% credibility

Picture Superiority Effect:

• Hear information → 10% recall after 3 days
• Add picture → 65% recall after 3 days
• Images = 6x more memorable than words
