Optimizing files such as Word documents, PowerPoint slides and PDFs for the web is a process that makes your files smaller. Smaller files are easier for instructors to upload and students to download. In some cases the same techniques also make your files more accessible for students using assistive technology.
-not all students have a large bandwidth (e.g., loading time)
-takes longer to download
Starting with Microsoft Office 2010, a new tool for Word, Excel, and PowerPoint called the Accessibility Checker is available. You can use it to check your Word documents for any issues that might make it challenging for a user with a disability. To learn more, see Microsoft's Accessibility Checker page.

Optimizing File Sizes
PowerPoint can be an effective presentation tool for the classroom. PowerPoint files (PPT) do not necessarily function well in online environments. PPT files with many images, animations, and audio and video clips may be too large for students to download. In addition, PPT files cannot be made truly accessible to people using adaptive technology.
Depending on your goal, here are some recommended ways to share material in your Carmen course that you presented in your face-to-face course using PowerPoint.
Strategies for Delivering PowerPoint Content
|Share Images Presented in Class
|Provide Lecture Notes for Review or Annotation
- Consider making your notes available in another format (e.g., as an HTML, Word, or PDF document).
A PDF document created directly from a PowerPoint file may be almost as large as the original and will not be accessible. This format also limits students' options for printing and note-taking.
|Deliver an Online Presentation
|Provide a Copy of your Original Presentation
Follow the tips below to decrease size and increase accessibility before uploading your file to Carmen.
Tell students that they will be downloading a PowerPoint file. Include "PPT file" or some other indication in the topic title.
