6. Show & Tell Prelab Presentation Quizzes Site Features Postlab Post lab report

7. Trauma report Technical Aspects Educational Aspects

8. Technical Aspects Good Accessing site –MyUCDavis/Banner –Flash & Quicktime downloading –71% reported no problems Using CD –Reducing Response time off campus –Low student usage 66% reported no problems Bad Early teething problems –System failure to recognize student –Quicktime download site change. –Browser diversity Student Familiarity with the technology –Too Little –Too Much

9. Educational Aspects Good Prelab –Reported better understanding of experiments compared to earlier courses. safety issues. –Good compliance with prelab quizzes Postlab –Students who were having difficulties with calculations were identified and given guidance. Bad Prelab –Equal preference for in-class vs. on-line prelab presentation. –Minimal improvement of independent lab performance –Increase course management demands on TAs Postlab –Creativity of error by 800 students kept us busy. –Initial exercise design lead to high student frustration level

10. Future Redesigning the post-laboratory exercises. –To include more feedback to student –To increase robustness –To tighten integration with lab course framework
