Keep Your Presentation Shorter!


Your presentation must be beneficial to both you and your audience. (It is never for you to show off your data or how hardworking you are!) One factor for effective presentations that sometimes is ignored but always important is the length of your presentation. Keep it short!

You have learned how to conclude. You have learned how to refine your experiment’s plans and presentation. Now it’s time to extract the critical points.

You must select the essential points for your presentation. How do you know what the most critical points are? They are the points that help you reach your presentation goal: (1) for your audience to share your thoughts and (2) for you to make sure that your understanding is right. Once you’ve finalized your most essential points, you can make your presentation.

Your other slides can be in the backup slides. For example, perhaps four pages could be shortened up into one sentence by saying, “Control experiments on concentration, temperature, reaction time proves these are not important factors.”

Your main topic often falls into one of the two ideas below:

1.          Newly learned technique or knowledge

Your benefit: A conscious understanding of new knowledge. Audience’s interest: Can learn something new.

2.          Newly developed thoughts or conclusion (could be from a stack of the experimental results)

Your benefit: Can test your logic and the quality of your experiments’ conclusion. Audience’s interest: Can understand.

Ideally, weekly group meetings become a record of your thinking and learning processes. Making your presentation concise is the best way to organize them both.



Good luck with your short presentation!
