Voice

One feature that distinguishes a reference list of HTML tags from a tutorial is the "voice" or sense of a person providing the information and guiding the process. I can imagine various sorts of students responding to these very different voices.

HTML Goodies by Joe Burns, PhD. has a friendly and conversational style. He tries to anticipate and answer questions. The site is well organized, helpful and reassuring.

Project Cool offers, in addition to the quickie class, a more thorough tutorial. This feels quite modern, professional and--(no other word for it)--"cool". Some students will prefer this site where the sense of a personal voice by a guide is minimized.

Web Adventure has one of the most consistent and "fun" voices providing training. Everything, from the Indiana Jones theme to the "Comic Sans" font style to the well considered backgrounds give a clear message: HTML is a pleasurable adventure.

HTML for Rookies has a very ernest tone by someone very eager and enthusiastic. He designed the site on a web TV rather than a computer, so really did have to know some HTML for that. I think this might appeal to a certain sort of student.
