- Switching between problem sets

Add a homework
Implementation
We decided to build a Web application, so we didn’t have to worry about users installing software, but this exposed our UI to the limitations of CSS. For example, we initially designed the grade entry form as a full-screen sheet that has horizontal and vertical scroll-bars, and the first row and first column are fixed to offer context. CSS made this hard enough that we didn’t have time for it.

- User 1:
- Task 1: Immediately got attracted to the home news page. He scrolled down to the bottom of the page, and selected Problem Set 1. He didn’t see the place to post grades. After couple seconds, clicked on Grading. Used Ctrl+F to search for Chad. Forgot to switch to Problem Set 1, but since the maximum grade was less than the point to enter, he soon found out, and switched to Problem Set 1. He used tabs to switch between blanks. He asked about whether there is a submit/save grade button. The facilitator explained that the system does auto-save.
- Task 2: Before Task 2, he tried on his own to type in the textbox, and found the system does filter. Task 2 went very smoothly. He searched the names in the box, and used tabs to switch between blanks.
- Task 3: He first clicked the dropdown menu for switching problem sets on the grading page, then searched under Grading dropdown menu. Quickly he clicked on Homework, and clicked on “+ Homework”. The rest of the task went smoothly except he got confused about Name and Filename, but soon he corrected that.
- User 2:
- Task 1: The user directly found "Post Grades". He forgot to change the problem set number, but later found out. He clicked on the row of the student, and entered the grades.
- Task 2:
- Taks 3: He completed the task with no difficulty.
- User 3:
- Task 1: The user was able to complete the task with some difficulties. He went up to teacher, chose the grades spreadsheet, and chose the appropriate parameters, but couldn’t enter the grades. He then noticed the grading menu and completed the task without difficulties from there.
- Task 2: He didn’t have any problems with this. Having seen the page from the previous task, he just started entering the grades, using the return key to advance between fields.
- Task 3: Immediately found the +Homework menu and added the homework without any difficulties.
