SlideShare doesn't allow you to create a slideshow or powerpoint presentation, but you can upload any presentation/s created elsewhere and your mp3 file and then synch your audio to make a slidecast.
- Embed slideshows into your own blog or website.
- Share slideshows publicly or privately. There are several ways to share privately.
- Synch audio to your slides.
- Market your your event on slideshare.
- Join groups to connect with SlideShare members who share your interests.
- Download the original PowerPoint / Pdf file
It's a way to create a presentation without the need for lots of equipment and software. Students could use the site to display their work and learn from comments of the community.
