  1. 1. Effective Technical Presentations
  2. 2. Why focus on presentations? <ul><ul><li> First impressions are important </li></ul></ul><ul><ul><li> Effective presentations are an “edge” in hiring and promotion decisions </li></ul></ul><ul><ul><li> Lack of effective presentations limits job assignments </li></ul></ul><ul><ul><li> The satisfaction of a job well done </li></ul></ul>
  3. 3. A process that yields an effective presentation <ul><li>Step 1: Plan </li></ul><ul><li>Step 2: Organize </li></ul><ul><li>Step 3: Prepare the Content </li></ul><ul><li>Step 4: Practice </li></ul><ul><li>Step 5: Get there </li></ul><ul><li>Step 6: Speak to the audience </li></ul>
  4. 4. Step 1: Plan <ul><li>Who is the audience? </li></ul><ul><ul><li>Make the level of the material appropriate to the audience </li></ul></ul><ul><li>What is the message? </li></ul><ul><ul><li>Have a clear point that you want to convey </li></ul></ul>
  5. 5. Step 2: Organize <ul><li>How long is the presentation? </li></ul><ul><ul><li>Present enough material to convey the message </li></ul></ul><ul><ul><li>Leave time for questions </li></ul></ul><ul><li>Follow the golden rule </li></ul>
  6. 6. The Golden Rule <ul><li>1) Tell the audience what you’re going to tell them </li></ul><ul><li>2) Convey the information </li></ul><ul><li>3) Tell the the audience what you’ve told them </li></ul>
  7. 7. An Introduction vs. an Outline <ul><ul><li>An outline presents a list of topics that the presentation will cover </li></ul></ul><ul><ul><li>An outline does not give the audience a reason to listen to you </li></ul></ul>
  8. 8. An INTRODUCTION <ul><ul><li> Who has done this work? </li></ul></ul><ul><ul><li> What work has preceded this? What is the context? </li></ul></ul><ul><ul><li> When was the work done? </li></ul></ul><ul><ul><li>But most importantly, </li></ul></ul><ul><ul><li> Why is this work important? </li></ul></ul><ul><ul><li>Give the audience a reason to listen! </li></ul></ul>
  9. 9. Step 3: Prepare the Content <ul><li>Where will the presentation be given? </li></ul><ul><ul><li>How large is the room? </li></ul></ul><ul><ul><ul><li>Determines minimum font size </li></ul></ul></ul><ul><ul><li>What presentation equipment is available? </li></ul></ul><ul><ul><ul><li>Use generally available technology </li></ul></ul></ul><ul><ul><ul><li>Take your own equipment </li></ul></ul></ul>
  10. 10. Content: A presentation is NOT: <ul><ul><li> a technical journal paper </li></ul></ul><ul><ul><li> a final report </li></ul></ul><ul><ul><li> a book chapter </li></ul></ul><ul><ul><li> a medium for conveying fine details </li></ul></ul>
  11. 11. Content: <ul><li>A presentation is effective when it uses the visual impact to </li></ul><ul><ul><li>Convey the message </li></ul></ul><ul><ul><li>Keep the audience’s attention </li></ul></ul>
  12. 12. Content: Keep it simple <ul><li>A presentation is not effective when slides are verbose and filled with lots and lots of text for the viewer to read. This type of presentation is better suited for publishing a paper or journal article and is not desirable for an oral presentation. Remember what a presentation is and what it is not. This type of slide is a real attention-killer and very difficult for the audience to follow. </li></ul>
  13. 13. Content: Only 2-3 Points per slide <ul><li>Avoid clutter </li></ul><ul><li>Emphasize the points you want to make </li></ul>
  14. 14. Content: Present ideas, not details <ul><li>Applies to </li></ul><ul><li>Text </li></ul><ul><li>Equations </li></ul><ul><li>Graphs, not tables </li></ul>
  15. 15. How many times have you seen this?
  16. 16. Content: Make it readable <ul><li>12 point 18 point 24 point </li></ul><ul><li>32 point 44 point </li></ul>Match the font size to the presentation room
  17. 17. Content: Appropriate to the medium <ul><li>Light letters on a dark background are best for projected images </li></ul>Dark letters on a light background are best for opaque images Dark letters on a light background are best for opaque images
  18. 18. Technology: Color <ul><li>Avoid low contrast or dark-on-dark combinations </li></ul>Avoid the UM red and blue Avoid the UM red and blue Light letters on a dark background are best for projected images Dark letters on a light background are best for opaque images
  19. 19. Ideas, not details: Equations Natural Response of an Unforced Parallel RLC Circuit
  20. 20. “ Busy” Equations Natural Response of an Unforced Parallel RLC Circuit
  21. 21. Equations that convey ideas Natural Response of an Unforced Parallel RLC Circuit
  22. 22. Conveying results Graphs, not tables V(0)=5v, i(0)=-6 mA Critical Damping: R= 10, L=0.4 mH, C = 1  F Underdamping: R= 20, L=0.4 mH, C = 1  F Overdamping: R= 5, L=0.4 mH, C = 1  F
