CH 15: Oral Presentations
15.1: Format of a Scientific Talk
Longer: Overview slide, intro of background material, purpose and results. Shorter: Extremely selective, focus on one to three main findings.
Topic needs to revolve around a specific question, the purpose of the study. Present after intro slide. Next, pinpoint take-home message with purpose.
Know your audience. Nonscientific: include more intro material and slides. Scientific: Less amount of intro slides, research question and importance.
Put the most important figure for core slide. Needs to be clear, uncluttered and immediately understandable.
Needs to be structured:
Next: Introduction and purpose of study
Subsequent: Findings with general approach
First slide: Overview of talk
Final: Conclusions and main supporting points
Title slide (optional)
Credit slide (optional): acknowledgment of those who contributed or financed
15.2: Preparing for a Talk
Take notes and memorize the opening sentences
Powerpoint, apple keynote, sliderocket, google slides and adobe presenter to design slides
Know audience and level of expertise
15.6: Question-and-Answer Period
Repeat the question so the audience heard it. Admit when you don't know the answer. Ask to rephrase the question. Direct answer to audience.
15.3: Designing Effective Slides
Font larger than or equal to 20. Use font such as arial or times new roman. Important info in larger text with italics, arrow or different color.
Text slides: brief bullet points, no more than 50 words per slide
5x5 rule: about 5 words per bullet point, five bullet points per slide
Avoid bright colors, nonstandard colors, and red/green (or blue/orange) contrasts. Titles in same place for each slide. No animated bullet points or slides.
Figures and tables need a title. No figure legend or caption on slides.
Use conference style presentation; inform or persuade.
Provide a key for figures. Line graphs: no more than 3 to 4 curves per graph.
Table: max of 4 columns and 7 to 8 rows, including title and heading. All text horizontal.
Visually well designed slides instead of heavy texts. Bar graphs over tables. Label axis titles and keys.
15.4: Delivery of a Face-to-Face Talk
Speak loud enough for the back of the room, deeper and fuller tones is more pleasant to listen to.
Try to not use distracting sounds, "hmm", "uhm", "okay" and "so".
Stick to time limit (1 to 2 minutes per slide), speak slower and clearer.
Best position for presenter is on the left or right side of the room or screen.
Use simple words and don't read the bullet point.
Confidence is key, look directly at the audience.
Arrive early, bring laptop (optional), bring several copies of printed version.
Use gestures to complement the presentation.
Feet should be securely on the floor unless you need to point to data. While showing slides, turn halfway toward screen, facing audience after.
Do not skip over information on slides.
Graph: explain each axis first then explain the data.
Table: describe row and column headings, then key findings.
Build transitions between slides.
Signal ending of presentation: to conclude, and thank you.
15.5: Remote Presentations
Similarities and differences for face to face and remote presentations.
Similarities: well organizes, use more visuals than text, text that is easy to read.
Differences: technology is key, can control the view of audience.
Start online meeting with "mute upon entry", good sound quality, test technology the day before.
