Plan for Chapter 2

This is a "guided discovery" lecture plan to teach students what the components of a URL mean.
(This was written in 1997, before the course was as large as it is today, so some parts had to be adjusted. Furthermore, web servers are becoming more sophisticated, and the days of finding "Error 404" messages seem to be quickly passing us by -- instead, one is more likely to find attractive search engines, well constructed pages, or find oneself redirected to a higher level within the site.)


  1. Props: paper folders and pages, plus a magnet or two.
  2. Explaining a URL
  3. Practice, and File Not Found
  4. Practice, Activity

Before the lesson, paper folders are prepared to represent the course site. The folders are inside each other, and have the folder name written on the outside. The URLs for the students' course pages start with, so the outermost folder has "users" written on it. Inside that folder is one titled "billp", and inside "billp" are two folders ("students" and "course").
Inside the "course" folder are papers representing each page of the students' course. Each paper has a page name written on it (e.g. ch1p1.html, ch1p2.html, etc.).

Class procedures: explaining a URL.
On the whiteboard, write out the URL of a lesson page the students have already done. Let's use this as an example:

Breaking it down into explainable bits (some of the following are instructions, and others are suggested paraphrases of what to tell students):

Class procedures: Practice, and File Not Found

Class procedures: practice and activity.
