Botonists everywhere needed an unambiguous way to describe the plants to do the taxonomy and create the cladograms and genus-species classifications. There was a time in biology when the movable type made it really cheap to produce books with lots and lots of words. ![]() I've been at very productive scientific meetings where someone puts up one or two slides of data and we spend the rest of the time in an open discussion around the whiteboard trying to figure out what it means (and which experiments should come next). Sometimes a picture is worth a thousand words. can be used singly or in combination for best effect. Uses of the different presentation aids need not be mutually exclusive-PowerPoint decks, whiteboards, handouts, etc. The way that a presenter uses those tools is likely to have a significantly greater impact on the effectiveness of the presentation than the presence or absence of those tools. Some are better accomplished with PowerPoint (or other similar presentation tools) than others. Are at least four very different communication tasks. I would like to tell everyone how to comply with.I would like to teach you how to perform.I would like to lead a group discussion about the implications of.I would like to present the results of.'In my experience, the best talks could not possibly be fully understood without the speaker.'" 'Frequently, in physics, presenters design slides for people who didn't even listen to the talk in the first place,' says Hughes. Elliot Hughes, a Rutgers University doctoral student and a participant in the forum, says the ban on slides has encouraged the physicists to connect with their audience. ![]() ![]() The talk became more dialogue than monologue as members of the audience, freed from their usual need to follow a series of information-stuffed slides flying by at top speed, managed to interrupt with questions and comments. 'We wanted to draw out the importance of the audience.' In one recent meeting, physics professor John Paul Chou of Rutgers University presented to a full room holding a single page of handwritten notes and a marker. 'Without slides, the participants go further off-script, with more interaction and curiosity,' says Andrew Askew. Hugh Pickens DOT Com writes "Amanda Solliday reports at Symmetry that six months ago, organizers of a biweekly forum on Large Hadron Collider physics at Fermilab banned PowerPoint presentations in favor of old-fashioned, chalkboard-style talks.
