Only the main ideas of the slide for a presentation should be there because the point of presentation slides is not to replace you as the teacher, but to help your students understand and remember what you are teaching. Your slides are there to support what you are saying, not to say it for you. Slides are only there as a visual for your audience, and a checklist for you to see to help smoothen your presentation. Having walls of text can also be detrimental because audiences will not remember what you are saying. Having more photos, figures and icons work better as visual memory triggers. They help your students remember what it is that you're saying. - Can you please answer my question if you are free?
