The best practice for utilizing notes during an oral presentation is to use brief note cards, which can help in staying focused while encouraging more natural interaction with the audience.
Step-by-step explanation:

This approach provides a balance, allowing the presenter to stay on track without reading directly from a detailed script, which can seem impersonal and make engagement with the audience more difficult. Rather than reading directly from notes or memorizing the entire presentation, using note cards can help maintain eye contact and foster a natural delivery. Additionally, deciding on whether to use a traditional written document or another medium, such as a slide deck or video presentation, depends on the topic and audience. For example, a PowerPoint presentation can effectively support a ten-minute talk, highlighting key points while allowing the presenter to elaborate verbally.
