Dr. Ray failed to follow the Modality principle. This principle stipulates that individuals learn better from graphics and narration rather than from graphics and printed text. In topic two, we learned that humans take in information through the eyes and the ears. The dual code theory states that humans take in information using the auditory and visual channel. The visual channel takes in both images and printed texts while auditory channel takes in sounds/auditory stimuli (Mayer, 2005). Dr Ray failed on the principle as she repeatedly uses images and printed texts together in the same slide. Despite the fact that she has clearly inserted voice in this multimedia object, the inclusion of printed texts and images in the same slide overwhelms the visual channel which is forced to take in both printed texts and images. Split-attention principle is the principle which can be applied in PowerPoint presentation in face-to-face crass room setting. The instructor integrates pictures in the PowerPoint to his/her narration of the course content (Mayer, 2005). Multimedia principle is the principle that I have closely followed; I learn better from a combination of pictures and words. Personalization principle is a principle I have broken severally as I usually find it difficult to use conversational style in multimedia presentation and often end up using formal style.
