On Line tools:

I spent the summer of 2010 immersed in watching tutorial videos from Lynda.com. At some point you will see my website join the 21st century as a result. I am a visual learner so watching, then doing, works for me. Not all people learn that way, but I do. I have watched many videos for Dreamweaver, CSS, jQuery, Fireworks, Spry, Excel, and Final Cut Express. I have many more tutorials on my list as I want to be proficient at web design as it is now done, Excel VBA, audio and video processing, and the use of Flash in Air applications for visualization of the solutions of dynamics equations. I am thoroughly enjoying my education. Note that Lynda.com is not a free resource but I found it reasonably priced and well worth the investment.

Wolfram Alfpha (http://www.wolframalpha.com/) was discovered by one of my students. It will give step by step descriptions of solving intergrals, for example. The program is also accessible as an app on my iPhone. Here is a link so you can test it out for yourself.

IntMath (http://www.intmath.com/) is another site that will do step by step math for you - precalc through differential equations. I recommend it to all my students.

If you want to see physics in action, I highly recommend the apps at PhET (http://phet.colorado.edu/). I have really enjoyed playing with and building my intuition from their simulations.

Please let me know when you find more such sites. I will add them to my own website.
