One way to supplement your powerpoint slide/lectures is to add an audio track/narration. It is ideal when creating an online class that if you do take your powerpoints from a face-to-face class to modify and change the content to fit an online environment. There could be content that could be supplemented through online discussion, or perhaps through student research through other websites, etc. You can also add an audio narration track to your slides, we use a program called Adobe Presenter to accomplish this task. Adobe offers a 30 day trial if you wish to explore this on your own computer, we can also lend out USB Headsets as well. Below is a quick tutorial on how the program is used.
