Showing pictures to the audiences to tweek their brains is an effective way to drive away the yawns (Burmark, 2011). A good presentation in my opinion should start by showing a picture and conversation may follow based on the answers the audiences give them. It can carry on a more interactive lecture. I have used this technique a lot in my middle school science class as well as during my experience substitute teach elementary school children. It works very well.
A lot of times the use of pictures that illustrates may be very useful in catching attention of younger audiences who have trouble comprehending abstract ideas (Burmark, 2011). An instructor may be able to pick out important catch phrases or keywords and use images to illustrate the words or main ideas. The size and the position of the images in a presentation is also very important (Burmark, 2011). In fact, without the proper size or positioning the use of image in the presentation may not be effective at all. Photoshop or other image editing softwares are available to adjust the size and position of an image for the optimum effect. Use of color or use of gray-scale , use of abstract shapes, use of images mixed with text may all enhance the quality of a presentation (Burmark, 2011).
