  1. Creative Communication using computer aided presentations Norman ScholfieldQueens UniversityBelfastUK

  2. Objectives At the end of this lecture you should be able to: • make clear scientific communications • show how audiences can be guided through a presentation • use graphics and animations to efficiently transfer information to a large audience • know the facilities provided by computer based visual presentations and how to exploit them Next slide

  3. Scientific communication • Clear and precise descriptions • Not easy - difficult for English speakers too • Scientific English not normal English • Scientific words - similar in all languages Next slide

  4. Conclusion The succession of transabdominal sex identification interpretation is needs : - professional skilled and acknowledge . - size and feature of sample - breeding season - transducer resolution The success of sex identification using trans-abdominal ultrasound depends on: - professional skill and knowledge - sample size and type - breeding season - transducer resolution Next slide

  5. Methods in presenting information Language and text Easy to construct a presentation Graphics Easy to understand complex ideas Easier to present if language skills poor Easier to follow if words inaudible Next slide

  6. Decide on the message What message should the viewer to take away? Should be remembered the next day at least. Your are advertising your work Focus the presentation around this Do not try to present too much material Next slide

  7. How to present the information Assume that your viewer is lazy Ideas easier to convey through graphics Helps if language poor Text should be used to fortify the graphics, summarise data and explain basic concepts Everything you say should be supported by visuals helps in language barrier Next slide

  8. What information to present • Information to audience • Main message (long term memory) • Information validating (supporting) main message (short term memory) Next slide

  9. Sequence of presentation • Title, who you are and affiliation (institute address) • Introduction (short and clear) leading to: • Aims and objectives • Methods (enough to understand results) • Results (convince the audience they are valid) • Discussion (precise and relevant link to current knowledge) • Conclusions (link to objectives) Next slide

  10. International English • Speak loudly and clearly • Everything you say must be supported by the visuals • Helps you • Keeps the audience focused • While speaking you are: • helping to guide the audience • expanding and clarifying details • controlling the focus of the audience • You are the boss! • If you loose the audience you are no longer the boss The talk Next slide

  11. Advantages of computer aided presentations (PowerPoint) • Static information (no advantage over slides) • Appearance of items in sequence (movement alerts visual system) • Construct graphics • Embedding graphs, images, videos • Creating animations to illustrate sequences of events or ideas Next slide

  12. Mode of presentation • Use your presentation as a cue • Never read out • from prepared paper notes or • from the displayed slide • Operate computer yourself (you have complete control) • May use mouse as pointer (if big) • Keep slides simple and limit information • Limit to 6-15 slides for 10 min (depends on information in each slide) • Use steady pace (rushing is for the nervous) Next slide

  13. Testing the presentation • Ask another person to assess your presentation • find someone who is nasty • Rehearse the presentation • have real audience • use the actual presentation room and computer if possible • check timing • gives you confidence • do not try to memorise it Next slide

  14. Constructing the presentation Next slide

  15. Results Next slide

  16. Bacteriologic cultures 1 gof fecal material RV broth RV broth Incubate 42 0c 24 hrs XLD BPLS Incubated 37 oc Incubate 37 oc 24 hrs 24 hrs Next slide

  17. Text • Maintain a basic font style and size throughout • Have short phrases with: • subtitles, • bullets or • numbers • Avoid long sentences • Text - clearly seen from back of room • -use a font size of 20-36 point Next slide

  18. Text styles This is not clear text This is moderately clear But this is clearer But not when small Blue clear here But this is harder to see Next slide

  19. This is not clear text • This is clear • Shadow lost here • But this colour combination is difficult to read • but red works here Next slide

  20. Beware of a graded background • It can start off clear • But then provide poor clarity at the other extreme Next slide

  21. Beware of a medium intensity or bright backgrounds • Because neither light • or dark coloured text stand out • The background should be subtle Next slide

  22. Font styles This is Arial which is good down to small sizes This is times roman which is less clear small or large Avoidgimmick fonts of any type Tahoma, Sans serif,Franklin Gothic are also good Next slide

  23. Font styles To highlight key words or titles use: • Bold • Italics • or larger fonts for titles • or a colour to highlight (but not to the distraction of other text) • Avoid underlining and • CAPITALS WHICH MAKES TEXT HARDER TO SCAN READ Next slide

  24. And avoid textures to the background Which make the clearest of fonts confusing to read Next slide

  25. Templates Microsoft templates mostly rubbish Reduces amount of space Less flexibility May cause visual confusion Make your own - keep simple Next slide

  26. Templates Template can be used for corporate identity Include titles Template ensures consistent background font style and size Next slide

  27. Graphics from internet Definition usually poor Validity suspect from books Depends on scanner Labelling usually too small Too much detail Static Therefore construct your own Simple line drawings showing only relevant details Well labelled Careful use of color Save memory Next slide

  28. Gastrin Prostaglandin Regulation of acid secretion Entero-chromaffin cell Vagal axons Parasymp Histamine AchR(M) H2R AchR(M) Parietal cell Too much info here Next slide

  29. Problems of using static text Viewer's attention will wonder to other items Need a pointer to high-light current item Only the pointer provides visual stimulation Next slide

  30. Using motion Fly in from side Zoom in or fly in from bottom or wipe in from the side or use a gimmick - but only once Next slide

  31. Constructing more complex animations Next slide

  32. Constructing more complex animations In the same way that text can "wipe in" same for graphics Next slide

  33. The menstrual cycle Ovulation Progesterone Oestrogen Very slow appearance canbe used to talk through Levels in blood 0 7 14 21 28 days Next slide

  34. Muscletension 20 msec Summation of contraction in skeletal muscle Summation Muscle membrane potential Action potential Next slide

  35. Motion paths To move an object over screen Next slide

  36. Muscletension Why no labelling here? Next slide

  37. H2CO3 + K+ Gastric Lumen Proton pump ATP Parietal cell H+ H2O + HCO3- Anion exchange pump CO2 Plasma side Cl- Next slide

  38. Changing the appearance of objects This is a gimmick - do not use Next slide

  39. H+ H+ H+ Gastrin (stimulates) H+ H+ Prostaglandin (inhibits) Entero-chromaffin cell Vagal axons Parasymp Histamine AchR(M) H2R Parietal cell AchR(M) Next slide

  40. Video clips Make sure that the video driver is present

  41. Use of colour Use to highlight important points Unity Use neutral or soft colors Try different shades of same color Otherwise create visual confusion Next slide

  42. Material&Methods Control group 41 cows The first group 31 cows 98 cows Treatment group 57 cows The second group 26 cows

  43. Sham injected cows (41) Total cows (98) Anti-depressant treated (57) Material & methods Prozac (31) Seroxat (26) Next slide

  44. The body condition score chart from Edmoson et al. J Dairy Sci 1989;72:68-78.

  45. Detection of antibody titer to Burkholderia pseudomallei infection in the Asian elephants (Elephas maximus) in Lampang Province by Indirect Hemagglutination test (IHA) Roschong Boonyarittichaikij* Pussorn Kumjun* Warut Wongkalasin** Chuleeporn Saksangawong*** Tulyawat Suttiphaet** Sitthidej Mahasawangkul**** Taweepoke Angkawanich**** Sarun Chansittivej**** Elephant and wildlife clinic, Faculty of Veterinary Medicine, Chiang Mai University

  46. What you see on your computer may not be seen by the audience Color (greens and yellows) Screen resolution Video drivers A picture may not embed into presentation file (only a link) - check the projected images Next slide

  47. Objective of the study Objectives To compare of bacterial culture of S. pyogenes, S. aureus, M. bovis, and N. gonorrhoeae between horses with normal conjunctiva and horses with conjunctivitis To compare bacterial cultures of S. pyogenes, S. aureus, M. bovis and N. gonorrhoeae from horses with and without conjunctivitis
