What are great sites to help an educator in 21st Century Learning?

I am amazed at sites such as Go2Web20.net. This site has opened my eyes to the expanse of cyber information that is out in cyber space. So much information is readily available. I can look up on-line account information, I can search and study new instructional math games and techniques, I can shop for what is of interest to me, and I can get on and just be social. I know that Google Earth, Web 2.0 tools, and Woopid are sites that I will continue to research to help me professionally. Are there other good sites in cyber space that are worth checking out?

What web 2.0 tools are beneficial to Algebra?

As a math teacher, I am curious if there are a lot of Web 2.0 tool programs out in cyber land that are actually being used in Algebraic and Geometrical concepts. I have enjoyed the two programs that I shared on the class site, but I am wondering if there are math programs that are being used that truly enhance what I am teaching. In particular, are there any web 2.0 tools that deal with quadratics and parabolas?! If there are, I would appreciate knowing what they are!

Blogs, Will they enhance student learning?

The more I work with web 2.0, the more I believe that student learning will be enhanced when students are blogging in math class. Students like communicating via digital format and it is a "new" way of learning. Blogs allow teachers to assess and enrich classroom learning. I believe the more I can incorporate blogs, the better all involved will be.

Teacher Tube

I am very curious if there are many people out in cyber land who have the same feelings that I do on the site "Teacher Tube"? My experience with it has been very frustrating. It takes a very long time to get on at times because of the amount of usuage, and when I am on it freezes up on me or I am "kicked" off. As well, the amount of space allowed for pictures and videos is very limiting. I had to go back and down size every photo and video clip I wanted to put on the site. Very frustrating. Am I the minority in my thinking of this site, or do others relate to what I am thinking?

Google Earth does have lots to offer math

As I have explored Google Earth more, I have answered my own question in an earlier blog! Wow, Google Earth has a lot of mathematical instructional options! I have discovered that when I get on Google Earth's 3D I can use the rule tool to do a lot with dimensions and scaling. I have discovered that I can explore fractals and modern geometry as well. Google Earth does open the door to new possibilities in instructing math concepts, and I look forward to discovering more.

How valuable is Google Earth in teaching Math?

As I have explored Google Earth, I find myself asking the question: " How can I best use Google Earth to help in my math instruction? I can't say that I have found a lot, as of yet, that will benefit me in mathematical instruction. I would appreciate if someone with more expertise than I could help me out in this area.

Will Social Bookmarking really enhance my web experience?

The more that I am on the web, the more clear it has become that social bookmarking will indeed be more efficient than just going to a search engine to look up desired web information. A search engine, by itself, is not always the best and most efficient way to locate desired information. Social bookmarking allows one to look at what other cyber-space explorers are looking at on a desired subject, and from there have a better vision on what avenues to take to get to site to get answers. Social bookmarking opens up a vast display of resources one can hook in to.

My big question, regarding social bookmarking, is, how efficient will it be as a math teacher to gain insight into what other math instructors or searching for and using in regards to web base information?
