Let's say you are presenting a report to the board of directors. You have two options:
- Explain it solely using words.
- Or use pie chart (visual aids) like below.
Which one is easier for the audience to understand?
Powerpoint is one of the visual aids available. Some things that needs visualization are better conveyed using visual aids. If I'm sharing about how I lose weight, it would be much more impactful and convincing to show a picture of a fat me than just saying I lost 15 kg. If I'm presenting interior design ideas, I would show some photos/ 3D rendering to the client. If I'm sharing complicated report/ data, I would put pie chart instead of reading all the items one by one and making the audience confused pr bored. So, Powerpoint is not "bad". It's a tool. Just like any other tool, it can be a powerful one when it's used effectively.
In the context of MMTMC, the usage of Powerpoint slides for a new speaker is discouraged. The reason is for he/ she to improve his/ her skill as a speaker without being dependent to visual aids.
