Presentations

Adapted from Kalée Tock and Ryan Caputo

Presenting your double star research effectively is a critical skill that complements your scientific abilities. Whether delivering a conference talk, creating a screencast, or explaining your work to the public, this guide will help you craft compelling presentations that engage your audience and showcase your discoveries.

Types of Research Presentations

As an astronomer, you'll need to master several presentation formats:

  1. Conference Talks: Formal presentations to other researchers (typically 10-15 minutes)
  2. Seminar Presentations: Longer, more detailed talks for departments or specialized groups
  3. Screencasts: Recorded presentations that can reach wider audiences
  4. Public Outreach: Presentations adapted for non-specialist audiences
  5. Poster Presentations: Brief explanations accompanying your academic poster

Each format requires adapting your content and approach while maintaining scientific accuracy.

Creating Effective Screencasts

Purpose and Audience

Screencasts are recorded presentations that combine visuals with narration. They offer several advantages:

  • Can be shared widely and viewed asynchronously
  • Allow for careful preparation and editing
  • Provide a permanent record of your presentation
  • Reach audiences beyond traditional academic settings

Technical Requirements

For high-quality screencasts:

  1. Duration: Keep scientific screencasts to 3-5 minutes
  2. Visual Elements: Include your face (webcam) alongside slides
  3. Audio Quality: Use a good microphone with minimal background noise
  4. Recording Software: Choose appropriate screen recording software
  5. Resolution: Record at high resolution (1080p minimum)
  6. File Format: Save in a widely compatible format (MP4 recommended)

Content Structure

Organize your screencast into these sections:

  1. Introduction (15-20 seconds):
  2. Identify yourself and your team
  3. State the research question clearly

  4. Hook your audience with significance

  5. Background (30-40 seconds):

  6. Provide minimal necessary context
  7. Explain what double stars are (for general audiences)

  8. Show an image of your star system

  9. Methods (45-60 seconds):

  10. Explain how you collected and analyzed data
  11. Show equipment and software used

  12. Simplify technical details appropriately for audience

  13. Results (60-90 seconds):

  14. Present key findings visually
  15. Highlight one or two main discoveries

  16. Show how your measurements fit historical context

  17. Conclusions (30-45 seconds):

  18. Summarize main takeaway
  19. Explain broader significance

  20. Mention next steps (if applicable)

  21. Acknowledgments (15 seconds):

  22. Show logos of contributing organizations
  23. Include QR code linking to additional materials

Adapting for Different Audiences

For Scientific Audiences:

  • Include more methodological details
  • Present comprehensive data
  • Use field-specific terminology
  • Focus on technical significance

For General Public:

  • Eliminate jargon or clearly define necessary terms
  • Use relatable analogies
  • Focus on "big picture" significance
  • Include more visual aids and fewer data tables
  • Maintain scientific accuracy while simplifying concepts

Engaging Younger Audiences

For presentations to students (middle or high school): - Ask questions to maintain engagement - Use vivid, relatable examples - Emphasize the excitement of discovery - Limit presentation to 2-3 key points - Test comprehension by creating questions they should be able to answer after viewing

Presentation Technique

Visual Design

Create slides that enhance rather than distract from your message:

  1. Simplicity: One main point per slide
  2. Text Limitation: Minimize text (bullet points, not paragraphs)
  3. Visual Emphasis: Let images and figures dominate
  4. Consistency: Maintain consistent formatting throughout
  5. Contrast: Ensure text is readable against backgrounds

Delivery Skills

How you present is as important as what you present:

  1. Clarity: Speak clearly and at a measured pace
  2. Engagement: Show enthusiasm for your research
  3. Eye Contact: Look at the camera when recording
  4. Body Language: Use natural gestures and expressions
  5. Practice: Rehearse multiple times before recording
  6. Script: Prepare notes but don't read verbatim

QR Code Integration

Extend your presentation's impact with digital connections:

  1. Creation: Generate a QR code linking to your additional materials
  2. Placement: Include the QR code on your acknowledgments slide
  3. Linked Content: Ensure your linked document contains:
  4. Digital version of presentation slides
  5. More detailed research paper
  6. Additional data or analyses
  7. Contact information

Incorporating Team Members

For collaborative presentations:

  1. Balanced Participation: Ensure all team members appear in the screencast
  2. Smooth Transitions: Plan clear handoffs between speakers
  3. Consistent Messaging: Maintain coherent narrative despite multiple presenters
  4. Technical Coordination: Standardize audio levels and video appearance

Preparing for Upload and Sharing

Platform Considerations

When sharing your screencast:

  1. Hosting: Upload to appropriate platforms (YouTube recommended for wide accessibility)
  2. Privacy Settings: Set to "unlisted" for controlled sharing or "public" for maximum reach
  3. Thumbnails: Create custom thumbnails showing key visual element and QR code
  4. Description: Include informative description with links to additional resources
  5. Accessibility: Consider adding captions for hearing-impaired viewers

Testing Effectiveness

Evaluate your presentation before final distribution:

  1. Peer Review: Have colleagues review for clarity and accuracy
  2. Test Questions: Develop questions that viewers should be able to answer after watching
  3. Timing Check: Ensure presentation stays within target duration
  4. Technical Review: Check audio quality, visual clarity, and link functionality

Common Pitfalls to Avoid

  1. Information Overload: Trying to cover too much in limited time
  2. Technical Jargon: Using specialized terminology without explanation
  3. Monotone Delivery: Speaking without vocal variation
  4. Poor Planning: Disorganized structure that confuses viewers
  5. Technical Problems: Audio issues or visual glitches
  6. Running Long: Exceeding the target duration

  • [ ] All team members appear and participate
  • [ ] Content is appropriate for target audience
  • [ ] Main finding is clearly stated
  • [ ] Visual elements are high quality and supportive
  • [ ] Audio is clear and at consistent levels
