Web 2.0: Do-It-Yourself PD
Here's a great way to grow your Web 2.0 teaching skills. Educator-friendly EduBlogs is sponsoring the Teacher Challenge, a series of themed posts that guide participants toward goals like "30 days to get your students blogging" or "30 days to ensuring privacy and student safety on the Web." The challenges are led by teachers, including Sue Wyatt, whose own Kids in the Mid blog is a must-visit. This month's challenge introduces you to 30 web tools that can support good teaching. If you can't read the post 'til June, no problem. These are permanent blog posts, and they have the how-to detail you want.
