This class would introduce fundamental tools in site building, and then expand design possibilities in web and interactive media. The first session would introduce the hardware of a webpage, how to create an empty page, planning a page (as suggested in the comments: web standards, semantic web, XML); the second would demonstrate how to fill the page from scratch using X/HTML and CSS; and the third would introduce Adobe Dreamweaver using the languages learned in the earlier sessions.
Perhaps the first session approaches the reverse engineering of a webpage, rather than a "workshop" of the teacher giving instructions to people sitting around with their laptops. The product could be displayed, and its approach and techniques explained so that a laptop is not necessary.
It would be great if students came with a project in mind, or something started from another class, refine or collaborate with other students, through the series or in just one of the meetings. If there is interest, the multi-class format would allow the integration of readings/ examples/ theory.
