(Scenario 1 - Looking Up Homework Assignment Due Dates)
This participant's most common goal is "looking up the due dates for homework assignments."This participant accomplishes this goal in the same manner that Participant #1 accomplishes his most common goal.
(Scenario 2 - Looking Up Project Assignment Requirements)
This participant's second most common goal is "looking for the requirements of project assignments."After achieving his first goal, Participant #2 is able to click on a link to any one of the assignments in order to obtain the requirements associated with a given assignment.
(Scenario 3 - Obtaining Class Hand-Outs)
This participant's third common goal is "obtaining class hand-outs if absent from class."To achieve this goal, Participant #2 starts from the CS 3604 Home Page, moves to the Professionalism Home Page, scrolls down the page, clicks on the "Calendar" link, scrolls down to the date of the class that he missed, and clicks on the link of the notes that he is missing. Participant #2 used "Therac 25 Incident" as an example. Clicking on this link, Participant #2 moves to "The Therac-25 Incident" page. Participant #2 checks the links provided on this page one by one. The "Class Notes" link takes this participant to a page with a list of links, each of which leads to one slide of material presented in class. To read a slide, Participant #2 clicks on the "next" links and the "Back" button several times. Then, this participant decides to read "An Investigation of the Therac-25 Accidents"; so he clicks the "Back" button twice and then clicks on the link to the article. This is a relatively long paper which is broken into five parts; several links are scattered throughout the text. Some of the links are linked to figures, and some of them (e.g., Side Bar) lead to other reference papers. The participant is uncertain whether he should finish reading the main paper and then go to the side bars, or read background papers as soon as their links appear. (Participant Comment: He typically reads background papers as soon as their links appear, but he feels that he gets "side tracked" and "loses the thread" he's attempting to follow.) At the end of each of the first four parts of the article, there's a "next" link which connects to subsequent parts of the paper. After reading all five parts, the participant clicks the "Back" button six times to get back to the Calendar.
