Judy from “Hey Jude” has put together a great overview on Web 2.0 and Web 2.0 tools including (blogs, podcasts, social networking, wikis, etc.) here:
It’s always nice to have quick reference for introduction for people who are unfamiliar with the terminology. She also has a number of embedded videos on the definition of Web 2.0 posted at this site. Check it out!
I was also perusing the links on her site and I found The Teaching Hacks Wiki which has a terrific overview of Web 2.0 vs. Web 1.0 for educators. There is also a section (being developed) that includes suggestions for applying weblogs/blogs in a classroom environment and provides suggestions per difference curriculum areas or disciplines.
I like the suggestion for using student blogs as a place to journal their reflections on the concepts that they learn.
An online math journal through a blog offers anytime anywhere access for students to access multiple students conversations around a particular concept. Educators can offer open ended questions to journal about, students can reflect on concepts that have been discussed in class and exchange ideas around those concepts. Students can regularly reflect on their own thought processes and share their successes and opportunities to rethink their own solutions in audio, textual, graphical or video format. Educators and students can model the appropriate use of mathematical symbols and vocabulary through a blog.

If you’re wondering how they can post mathematical formulas to the web on their blog other than writing them down and scanning them in. There is a Mathematical Markup Language which allows you to code for mathematical formals and notation to be published via the web. Though this may be hard to learn initially, there are some wysiwyg editors that can be used. I guess I would buy a cheap scanner for my classroom and have students scan in their formulas or diagrams to view via the web. All students therefore can share access to the shared formulas and either learn from their peers or help them solve problems that they are having difficulty with.
