In addition to finding some really great sites, I also found some junk, and more than once I was led to a potentially promising site, only to find it a skeletal address still under construction. I quickly learned that not all chemistry sites offer the high academic standards and universal accessibility of the Purdue sites. Not a tutorial per se, this site is a good overview of the philosophy of academic instruction on the Internet. The author dispels skepticism about the role of the Internet without preaching to the converted. He offers suggestions for designing and making the most of a chemistry department's web site.
Links allow the user quick access to other schools' sites, exercises, tutorials, software, etc.
I recommend this site as a first stop on an introductory tour of the world wide chemistry web. No substantive knowledge of chemistry is required in order to appreciate the author's message. If you can tolerate the jocular and at times irreverent tone of this zany grad student author, you will benefit from the brief, plain English reviews of first semester general chemistry topics found at this address. New topics and coming attractions are clearly marked in the index. The site is not interactive, but it does provide clear examples.
