Teaching using technology is easy to do badly. I probably use too much gadgetry in my presentations and interactions with my students, but that's because I'm a nerd. Nonetheless, here are a few things I think are key in interacting with web aware students on a daily basis.
I use this stuff because, a. I think the students get a better educational experience from it, b. the use of these tools exposes your work to many other interested parties across the world, and c., see above about me being a nerd.
A few skills and the applications which serve those skills you'll need to pick up:
Getting Input
1. Content. Where does all the content come from? It comes from you, your reading and background, your training and professional outlook, social media, and traditional media online. when it comes to looking things up, stop going to 20 websites a day. Get the website updates to come to you. Use an Rss reader for this, like google reader.
2. Feedback. You can get lots of free and instant feedback using online surveys. Have a look at this to find out how to get started.
3. Email. Set rules about this, or you'll drown in it, but everyone uses email these days, and lots of your input from students will come from here. Here's one set of articles about how to deal with email well. Or better, at any rate.
Producing Output
1. Twitter. This is a service that lets you broadcast messages to those who choose to follow you. You can follow other people you're interested in. Give it a go.
2. Vimeo. This is a video streaming service, kind of like a high end youtube. I use it to share lectures.
3. Upload photos and video to the web. Think charts, graphs, and slides, not pics of your kids. But put them up there too if you think it will help the students.
4. Record audio and presentations. I use screenflow, but you can get many tools to help you do this.
5. Understand that your class, as it exists online, is a community. This community requires some management. Here are a few tips and tricks to help you do this. Most of these tips actually boil down to having a bit of cop on and doing your best not to be a dick, but still, have a read.
6. Share your presentations online. Use slideshare. It's best in class.
I've also written a much larger teaching colophon here, have a look, let me know what you think, and if you'd like to know more, drop me a mail.
