Students create presentations all the time, sometimes well, sometimes very badly. We often attempt to set the bar high through modeling our own work or displaying exemplary projects other students have completed. But what happens after your students leave your classroom? Too many students often forget. Slideshare, paired with your blog or website, can reconnect students to a solid visual standard anytime they access your online resource.
Slideshare is a web-based application which allows you to upload presentations to the web and then display them to as many or as few people as you would like. If you would like to keep your audience small, you can e-mail individuals a secret web address where they can view your show. Or, if you’d like to broaden your audience, you can paste your show into your website or display it to the members of the Slideshare community. Students can review your presentation anywhere they can access the internet.
Used in your classroom, Slideshare may actually increase your students’ engagement by giving them an authentic audience. After certain Internet safety measures are taken, posting student work on the web can encourage students to produce works they can take pride in, and it enhances the perception that correct citation is an issue of honesty, not simply a requirement of the rubric.
Here’s an example of one publicly available presentation from Slideshare, embedded into this blog:
Tech 4 Practice 
It seems like more than anything, Slideshare would be a matter of convenience. If I have presentations like PowerPoint out there on the web, then no matter where I am, I could access them without my jump drive etc. It would also be useful to have students post their own to your website (or a website) and then view them from home without carrying around papers etc. This just makes life easier.
You raise a good point, Megan, about the mobility of this technology. With Slideshare we lose a bit of the bells and whistles (animations, transitions, sound), but we do gain some things, especially in terms of distance learning. Student could access your notes at a time convenient to their schedules. Colleagues from around the globe could review your presentation and give you feedback. These are powerful gains, indeed.
