Final answer:
The textbook recommends limiting slide text to six lines, using consistent colors, and ensuring slides are accessible and follow a clear structure. Capital letters should be avoided as they can be harder to read.
Step-by-step explanation:
The textbook recommendations for preparing slides include limiting the amount of text to no more than six lines per slide and sticking to a limited number of colors while using them consistently. Using all capital letters is not advised as it can make slides difficult to read and may be perceived as shouting. It is also important to keep a consistent visual style throughout the presentation, including font choices, color schemes, and backgrounds. When designing slides, accessibility should be considered to ensure that all members of the audience, including those who are visually impaired or rely on an interpreter, can fully engage with the content.
Presentations should have a basic format similar to other forms of writing, with a clear introduction, supporting points, and conclusion. The media included in the presentation, whether images or audio clips, should be of high quality and large enough to be easily seen and heard by the audience. Finally, it is helpful to have a concise outline of the main ideas to ensure that the presentation remains focused and easy to follow for the viewers.
