Even though PowerPoint presentations are not considered accessible for all users, there is nothing wrong with offering online PowerPoint presentations as long as an second accessible HTML version is offered as well as a link to the free PowerPoint viewer. PowerPoint documents posted online should always have a second accessible HTML link. Unfortunately screen readers such as JAWS usually cannot successfully navigate PowerPoint documents unless they have been markedup for accessibility with the Accessible Web Publishing Wizard.
If you provide a link to an actual PowerPoint presentation: Please also include a link to the free PowerPoint viewer software for non-JAWS users using Windows or the free PowerPoint viewer for Macintosh OS users who may not have Microsoft Office installed on their computers.
If the PowerPoint presentation has audio multimedia then captions and/or transcripts will be required. Check out the WebAim's recommendations for PowerPoint accessibility from WebAIM.org.
Illinois Accessible Web Publishing Wizard for Microsoft Office can be used to make PowerPoint HTML presentations more accessible.
Blackboard Issue: Screen reader software such as JAWS can not successfully open Microsoft Word documents or RTF documents embedded in frames in web pages -- which is exactly the situation with Blackboard. Partial Solution: You can help by always labeling links to embedded Word or RTF documents, e.g.: class overview.rtf (RTF format)
See an example of how you could provide both a PowerPoint presentation and accesible HTML.
