(there are some who recommend dark text on a light background if the room is large.) (note: if you&#8217;re using transparencies and an overhead projector, don&#8217;t use dark backgrounds.)<\/li>\n<li>pay attention to how different colors go together, and remember that the shades you see on your monitor are not necessarily the ones you&#8217;ll see when projecting your presentation.<\/li>\n<\/ul>\n<h3>text and white space.<\/h3>\n<ul>\n<li>blank space on a slide is important &#8211; as a general rule, if you find yourself wanting to reduce the font size so that you can get more text on the screen, it&#8217;s probably a good idea to consider redesigning the slide so that you have less text on it.<\/li>\n<li>the standard limit is either 7 x 7 (seven lines, no more than seven words each) or 5 x 5 (five lines, no more than five words each) on each slide.<\/li>\n<\/ul>\n<h2><a name=\"practices\"><\/a><strong>suggestions for uses of slides<\/strong><\/h2>\n<p>if you&#8217;re using slides to illustrate and\/or\u00a0<strong>support a lecture <\/strong>&#8230;..<\/p>\n<ul>\n<li>remember that lecture notes on a slide play a different role in a lecture than do lecture notes that only the lecturer can see. if you try to make them play the same role, you&#8217;re likely to find students reading your slides instead of listening to you.<\/li>\n<li>you can use slides in lecture to\n<ul>\n<li>list major points of your lecture. several of the major points might stay on the screen as you develop each of them in turn, providing a way for those listening to the lecture to place each point in the larger context.<\/li>\n<li>list important terms. again, one slide with several terms might remain on the screen for some time, allowing you to refer to each of them as you introduce them in your lecture.<\/li>\n<li>illustrate with images. sometimes a picture can make words worth much more than they are without the picture.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p>while instructors tend to think of lectures when they think of using visual aids in teaching, images can also be used to\u00a0<strong>support classroom discussions <\/strong>.<\/p>\n<ul>\n<li>move participants through stages of understanding. suppose you have a discussion in which students are asked to work together to analyze a dataset and reach a particular conclusion about the dataset. you could begin with a slide that presents the dataset in a disorganized way and ask the students to work together to identify patterns. as the discussion progressed to identify patterns that you would expect students to identify, you might then present a slide that showed these patterns. the discussion would proceed, supported at each stage by a slide that exhibited the patterns identified at that stage.<\/li>\n<li>take, organize, project real-time notes on discussion. students often take notes during a discussion. have students take turns serving as primary notetaker for the discussion, recording these notes in real time in a word processor projected onto the screen. students develop the skill of recording and organizing information as a discussion is taking place. moreover, these notes are in electronic form and therefore easily revised and reproduced. notes taken in one class session can provide the basis for discussions later in the term.<\/li>\n<li>organize small-group work. if you have students working in small groups, you can put prompts for group work on slides that are projected as the students do their work. you could move students gently from one stage to the next by changing the prompts.<\/li>\n<\/ul>\n<h2><a

that it can convey information as a stand-alone document, but he doesn&#8217;t address ways that a slideshow can enhance an in-person presentation.<\/li>\n<li>for a different approach to using
