When adding lecture presentations to an LMS like Sakai the main considerations are preserving the original layout and content of the PowerPointPresentation, ease of use for students to review, access, making notes and printing, and how quickly information can be updated. The nature of your course will determine which of the following formats work best.
Adding PowerPoint presentations to Sakai can be simple, but you need to follow a few simple steps that are specific to your computer, software and teaching as simply uploading the original .ppt file often runs afoul of Internet Explorer's Blocking of Microsoft Office Files for security reasons.
This article is intended to help you ready your files for Sakai and uploading them to the Resources tool using your specific software and computer.
