Confluence of things…
1. The need to use technology because of student numbers
2. The development of appropriate technology
3. On-campus technical support
On-Campus Technical Support
• pre 2002 – 2 people
• Presently: Educational Development Centre – many people
• Many colleagues now supporting each other
• Technical feedback from students

4. Acceptance by students
Acceptance by Students
1992: 2 students out of 550 had email
2007: 95% of CHEM 1000 students have fast internet access at home
Student Feedback
... helps us prepare for lectures and have questions ready
... good for big rooms like theatre B
... makes things easier to understand for visual learners
... students might get the idea that they don’t have to go to class. That’s what I did last year and that’s why I’m still in first year.
…chemistry didn’t suck as much as my other courses
