Which guideline should instructors follow when developing audiovisual components?

Using parallel structure on each slide or image is essential because it helps to create a cohesive and visually appealing presentation. This guideline promotes clarity, making it easier for the audience to follow along and understand the content being presented. When the layout, style, and format of each slide are consistent, it reinforces key concepts and aids in retention. The audience can focus on the message rather than being distracted by varying formats or structures.

In contrast, utilizing a variety of fonts can lead to visual clutter and confusion, making the material harder to read and comprehend. Limiting the use of images might suppress essential visual aids that help in understanding complex topics, while incorporating background music can distract from the primary message if not used thoughtfully. Each of these alternatives fails to emphasize the importance of consistency and clarity that parallel structure provides in audiovisual presentations.
