Presentation guides are helpful for any class that will speak in front of an audience. A presentation guide needn't be long, but should contain a few common parts.
One, include expectations. Students should not chew gum, interfere with other presentations or curse. State simple rules such as these because not everyone may think of them. Two, include a basic assessment grid. You may have a rubric for each presentation, but when students give shorter presentations, you may want a standard "go to" rubric. This will also show students the basics of how you will always assess them. Three, provide a time-line for students. Although in high school, students probably do not realize that they should practice before presentations. Include how to practice timing a presentation and eliminating "fillers" such as 'um' and 'uh.' Address stage fright and tools for limiting nerves. Most importantly, students should prepare so they are comfortable presenting.
Finally, include any other information that is helpful for presentations. This could include visual aid guidelines, ways to cite sources and other speaking tips.
