Visual aids are very useful during presentations, as they can help convey a message in a way that is clearer and more relatable than words.
One visual aid that is particularly useful is a graph. Graphs can be used to represent statistics. In this case, you can provide data on the type or the amount of technology of a classroom, and you can display this data on a graph.
Another useful aid is photographs. You can show pictures of students using technology in the classroom. This can also serve a rhetorical purpose, by forcing the audience to connect positive images with the idea of technology in the classroom.
Show the people a graph. Pie
graphs are best when you want to prove a point in comparison. It's easy
to understand. Pictures, everyone doesn't like a bland presentation
pictures are always a necessity to give a feel about your subject. For
example in this situation I would use computers or pictures of students
learning from computers. Last but not least I would use a video in some
cases to show real life experiences such as a classroom doing an
experiment. It helps visualize as well.
Hope it helps I got this right in E 2020 so all ya'll kids enjoy!
