Preparation Phase
PowerPoint Basics
Font
- Using Sans Serif fonts instead of Serif fonts makes it easier for the audience to read the text quickly. Examples of Sans Serif fonts include Arial, Comic Sans, and Trebuchet
- Type size should be within the range of 18 point to 36 point, except adding references at the bottom
- Avoid using all capital letters
Color
- The color combination between letters and background should be high contrast
- A dark blue or black background works best for talks in a large room
- Dark letters against a light background are best for small rooms or teaching
- There is no need for a university logo to be on each slide
Layout
- Every slide should have a heading, a simple but purposeful sentence. For more effective headers, consider:
- Using questions as headers to simulate a “conversation”
- Using the assertion-evidence structure
- Limit text blocks to no more than two lines each
- Lists should contain no more than 3 items, and “unveil” the list one by one
- Be generous with empty space, especially at the top and the bottom
Style
- Include a simple image on every slide
- Limit the number of items on each slide; each slide should make just one or two points, and explain the points completely
- If you’re not going to take the time to explain it, get rid of it
- Avoid fancy transitions between slides unless you have a good reason
- Don’t drown the audience with data, less is more
Three Functions of Slides
- Visual repetition of key points: to draw attention to & reinforce key messages
- Complement spoken text: additional info not said
- Replace Speaker (temporarily): e.g., a video, show whole paragraph or table & ask audience to read while keeping silent
The structure of slides: start broad, get specific, end broad
- Start with the biggest questions and get progressively more specific
- In the middle of the talk, go into depth, but use the home slide to make transitions (enable the audience to tune back in)
- To conclude, reiterate the main conclusions and go back to the big picture
- During Q&A, put the summary slide back up again
Review Each Slide
- Make sure each slide serves its PURPOSE
- Each slide has MAIN POINTS thatthe audience must see within 5 seconds
- Check whether the slide will make the audience LISTEN or spend some time looking at the slide
During Presentation
Useful Slide Transition Wordings
- “Now, what are …?” (use of questions)
- “My next point is …”
- “Now that I’ve finished talking about …, let’s move on to …”
- “You’ve just seen …, so we’ll now turn out attention to my second point: …”
- “In addition to the factors we have discussed, I want to add …”
Remind Vocal Dynamics
- Change pace to emphasize key points
- Change pitch to create interest
- Change volume to emphasize contrast
- Punc-tu-ate syllables and words for emphasis
- Pause before important information to provide anticipation
Avoid Vocal Distracters
- Vocalized pauses (um.., er.., ah..)
- Filler words (ok, you know, actually)
- Breathlessness
- Voice dropping or rising at the end of a sentence
- Mumbling /slurring
Q&A Session
Different types of questions:
- Clarification questions: dealing with points mentioned in the presentation
- Application/Significance questions: relating to the value of research
- Problem questions: regarding perceived problems with research;
- Miscellaneous questions: concerning minor issues related to research
Handling Questions
When don’t know the answer:
- Simply say “I don’t know, but…”, to say what you would do the get the information to the asker
- Or if you have the hunch, still say, “I don’t know, but I will follow up with you as soon as I can.” Then, follow with your hunch: “But my hunch is, the answer may sound like this…”
When the multiple questions are asked one after another (Machine gun questions):
- Pick one or two that you still remember and answer them
- Ask the asker to repeat the question
May not be a question but a statement:
- When the people take a breath, start to paraphrase what has been said and ask a question for him/her: “So what you are saying is … "
When someone asks a question with loaded emotions:
- It’s best to acknowledge the emotion in a generic term: “It sounds like you have a lot of passion on this topic…” and go ahead and paraphrase the question
