Giving Feedback onStudents’ PowerPoints The Cain Project in Engineering and Professional Communication WORKSHOP SERIES
Teach Students How to Decide • As new technologies emerge • As audiences change • Academia/ industry/ public • Disciplines • Diverse cultures (globalization) • As their purposes change By emphasizing processes and criteria
Shifting the focus of feedback This title is too short. What will the audience expect to be on the slide from this title? There are aren’t enough labels here. If you point to this image during your talk and someone misses it, will they be able to understand? This doesn’t seem to be related to the previous slide. How does this slide work in the series of slides so far? PRODUCT PROCESS
Ask Questions Related to Criteria • Is it accessible? • Is it comprehensible? Understandable? • Is the information usable? • Is the slide interculturally or interpersonally appropriate and compelling?
Accessibility Questions • Is information organized logically? • Are whole to part relationships obvious? • Are cues consistent, noticeable without being overwhelming? • Are images legible, familiar, and interpretable? • Is text easy to read?
Accessibility Cues • Headings and titles • Hierarchy • Indentions • Point size, point size • Layout in space • Legibility (contrast, font, color) • Conciseness
Slide Template Errors • Busy/complicated: can audience get what they need? • Wrong for room: are the slides easy to read? • Well-lit room: use light background / dark text and visuals • Dimly-lit room: use dark background / light text and visuals
Good for print E Serif (“tail”) Such as Times New Roman Good for projecting E Sans Serif (uniform shaft width) Such as Arial Errors in Choosing Fonts
Errors in Choosing Fonts • Contrast between background and text • Size of font • Type treatment of font Drop Shadows Reduce Legibility
The ideal anesthetic should quickly make the patient unconscious but allow a quick return to consciousness, have few side effects, and be safe to handle. Too Much Text! • Ideal anesthetics • Quick sedation • Quick recovery • Few side effects • Safe to handle
Lack of Hierarchy • Bullets help your audience • to skim the slide • to see relationships between information • organize information in a logical way • For example, this is Main Point 1, which leads to… • Subpoint 1 • Further subordinated point 1 • Further subordinated point 2 • Subpoint 2
Content-Poor Titles Titles should give the message of the slide, for example… “Results” suggests the topic for a slide “Substance X upregulates gene Y” (with data shown below) shows the audience what is observed
Errors in Lists For easy accessibility, lists should be in same grammatical form Parallel: Use keywords Avoid wordiness Opt for bullets Not Parallel: Use keywords Wordiness is bad You should opt for bullets
Revise for Grammatical Parallelism • Not Parallel: Criteria to Assess Alarm System • Price • Effectiveness • How easily the alarm could be installed • Parallel: Criteria to Assess Alarm System • Price • Effectiveness • Ease of installation
Graphics That Can’t Be Read Small image stretched to graininess Large image reduced to illegibility
Errors in Slide Show Effects • Slow effects • Fancy animation • Animation used without purpose • Inconsistent use of animations or transitions
Comprehensibility Questions • What helps the audience understandthe argument of the presentation? • What connects one slide to the rest of the presentation? • What evidence is presented? Is the evidence adequate, appropriate?
Comprehensibility Cues • Relation of title to bullet items • Repetition of key words • Logic of headings • Labels on figures, diagrams, photos • Relation of each slide to main point • Quality of evidence/ support
Usability Questions • Are sources indicated? • Is contact information supplied? • Is anything lacking that the reader needs to take action? • Is the sequence complete? Are steps missing? • Are warnings provided, if necessary?
Usability cues • Citations and bibliography • Speaker’s name, affiliation, contact information • Symbols to indicate cautions, warnings • Handouts
Interpersonal / Intercultural Questions • Do the slides reflect the character & expertise of speaker? • Are the slides consistent with the culture and values of audience? (for example, values tradition or values innovation)
Cultural, Interpersonal Cues • Slide design • Familiarity of genre system • Appeals to the values of audience

What is Telemedicine? • Telemedicine utilizes communication technology in order to move medical information rather than patients, and it is being used as a tool to bridge inequalities in access to medical care between rural and urban areas in the U.S • It is most commonly used in the visually-oriented fields such as radiology and dermatology
What is Telemedicine? • Distributes medical information and expertise • Used primarily to transmit visual medical data • radiology • dermatology • Targets populations with limited access to medical care • rural areas • remote areas • Bridges inequalities
