Plymouth University's CDE Model: Content, Delivery, Engagement.
Plymouth University’s (2019) CDE Model

What makes a good presentation?

Plymouth University’s (2019) CDE model shows the elements of an effective presentation.

  • Content: plan a logical structure that shows your knowledge/research.
  • Delivery: communicate your ideas confidently and effectively.
  • Engagement: make a connection with the audience.

1. Planning

Beginning:

  • Introduce yourself: who are you?
  • Outline the topic: what is your talk about?
  • The hook: interesting facts, statistics or quotation to grab the audience’s attention.
  • Justify: why is this a topic of interest?
  • Coming next: what key points will you discuss?

Middle:

  • Divide the topic into key points to discuss.
  • Consider what details or examples you might mention.
  • Plan how much time you’d like to spend on each point.
  • Consider using a planning grid such as the one below.

End:

  • Summarize: what main points were covered?
  • Memorable ending: state your final point; have a call to action; end with a rhetorical question.
  • You can also invite questions.
  • Prepare by thinking about what your audience may ask.
  • If you don’t know the answer, say ‘Can I come back to you?’ or open it up to the audience ‘What does everyone else think?’

2. Designing Visuals

  • The visual appearance of your presentation is important.
  • We learn 90% of information visually and only 7-11% through hearing (Bradbury, 1995, p. 64).

Text:

  • Use clear headings to guide your reader.
  • Bullet point information & avoid too much text on each slide.
  • Aim for around 25 words per slide (Van Emden and Becker, 2016, p. 40).
  • Use sans serif fonts that are easy to read such as Arial, Calibri and Veranda.
  • Aim for around 24 point font for PowerPoint slides.
  • Pick a font colour that contrasts with the background.

Graphics:

Colour:

  • Choose a consistent colour palette to use throughout.
  • Use the colour wheel (beside) to aid this.
  • Complimentary: •Opposites in colour wheel e.g. blue and orange.
  • Monochromatic •1 colour in different shades and tints.
  • Analogous •3 colors next to each other on the color wheel.

3. Delivering

  • Avoid speaking too quietly or quickly. Remember to pause between points.
  • To improve delivery, aim to rehearse before the talk.
  • Create prompts such as a script, PowerPoint notes or A5 index cards.
  • Try the Orai app to test your delivery, or ask your friends to watch.
  • What worked well? What areas do you need to improve?

Non-verbal communication:

  • Keep your body language open rather than closed.
  • Closed body language can include folded arms, crossed legs and hands in pockets.
  • Instead, aim to engage your audience with eye contact.
