Editor's Notes
- This template can be used as a starter file for presenting training materials in a group setting.SectionsSections can help to organize your slides or facilitate collaboration between multiple authors. On the Home tab under Slides, click Section, and then click Add Section.NotesUse the Notes pane for delivery notes or to provide additional details for the audience. You can see these notes in Presenter View during your presentation. Keep in mind the font size (important for accessibility, visibility, videotaping, and online production)Coordinated colors Pay particular attention to the graphs, charts, and text boxes.Consider that attendees will print in black and white or grayscale. Run a test print to make sure your colors work when printed in pure black and white and grayscale.Graphics, tables, and graphsKeep it simple: If possible, use consistent, non-distracting styles and colors.Label all graphs and tables.
- This is another option for an overview slide.
- What will the audience be able to do after this training is complete?Briefly describe each objective and how the audience will benefit from this presentation.
- Use a section header for each of the topics, so there is a clear transition to the audience.
- Add slides to each topic section as necessary, including slides with tables, graphs, and images. See next section for sampletable, graph, image, and video layouts.
- Keep it brief. Make your text as brief as possible to maintain a larger font size.
