Mike: Your question doesn't make sense. Basic web would be done using HTML and note pad. Dreamweaver is a pro level development tool. Plus NOTHING done in dreamweaver can't be done in notepad, its just faster.
Most classes I've seen at least start with DreamWeaver. It's not that it can't be taught using a text editor, it's just that most people are used to the concept of a word processor and that gives them a starting point. Looking at a program that looks like Word that they use every day is less intimidating than looking at a Notepad screen full of HTML.
What actually got me started coding in a text editor was Front Page. Usually a page wouldn't look quite right so I'd have to go in and edit the HTML. It happened often enough that I finally gave up on FP and just started doing it myself.
It all boils down to personal preference. For me it's easier to write straight HTML and stay out of the WYSIWYG editors. Plus I'm OCD enough that I don't like giving up the control on how my code is formatted. For others they are used to DreamWeaver or NVU and use those programs.
Of course if the assignment is to "do this in DreamWeaver" than the discussion is moot
