In many cases I do not want my class notes available until the day before class, and then I want the link to become inactive after the exam. In those cases I use time triggered links:
| Date | Topic | Reading Assignment |
|---|---|---|
| 3/26/01 | Notes Link #1 | Chapter 10 |
| 3/28/01 | Follow up | Chapter 10 |
| 4/2/01 | Notes Link #2 | Chapter 11 |
| 4/4/01 | Follow up | Chapter 11 |
