Tone in our PowerPoint Presentation

For one of the assignments during class, we were assigned to make a presentation and perform it during class. In our rough draft we were given feedback, based off of what we had in our PowerPoint. For our final grade, I feel that we were predominantly graded on the PowerPoint presentation instead of what we were saying. I feel that in order to grade based on rhetoric in this instance, we should have been graded predominantly on what we were saying instead of how well our PowerPoint was done. The main argument of rhetoric in this presentation was what we were saying and how the words were delivered. I felt that someone could have had a great PowerPoint, but not have delivered their message well. I feel that I am a stronger speaker than writer, so I avoided writing much on my PowerPoint, so that people would pay more attention to me. The most important part of the presentation is the tone and way the words are delivered to convince your audience to care about the issue. I  feel that since it was our first presentation this entire semester it was also nerve-racking to be up there which played a major part of the delivery of the message. Because of this, I feel that we should have had some practice and pointers with our tone, alongside other rhetoric devices, so that we felt more prepared for the PowerPoint. I was very surprised at how well our class presented, and thought they for the most part did well in engaging the audience.
