What should be avoided in the presentation materials?

Using visual aids as substitutes can undermine the effectiveness of a presentation. Visual aids should enhance the material being presented, not replace critical information or the speaker's role. When they are used as substitutes, they may lead to a lack of engagement, confusion, or misinterpretation of the material. Effective presentations rely on a combination of verbal communication and visual support to provide clarity and maintain the audience's interest.

In contrast, highly creative elements can be beneficial in capturing attention and making the content memorable, while props that add value enhance understanding and retention. Similarly, costumes can be useful for emphasizing key concepts, particularly in educational or thematic presentations. The goal should always be to support and reinforce the presented information effectively, rather than allowing any visual component to detract from it.
