I recently found out about Stump the Teacher, a blog by Josh Stumpenhorst, and the excellent collection of tutorial videos he has on the blog.

The videos are well done and easy to follow and understand. Topics include: Google Docs, Blogger, Greenscreen, Twitter, Evernote, and more.

These are great for people who want to get started with any of these tools, or even learn a few new things.

Definitely a resource to add to your list of great, on-demand, tech professional development sites.

Mary Fran's Google Sites Tutorial is an excellent resource for anyone using Google Sites.

She has done an excellent job of breaking down different aspects and functions of Google Sites into an easy to read and follow format.

The site (created on Google sites of course) includes getting started, the basics, editing, inserting gadgets, using layouts and templates, and much more. She has video tutorials, links, and examples of sites and also has a section specifically for educators.

If you use Google Sites or want to create your own web site using Google Sites, I highly recommend this site. It is also a great resource for students who are using Google Sites.
