Motivation Improved educational experience in the
laboratory
  • Familiarize students with equipment and
    chemistry.
  • Focus students attention to the principles
    underlying the chemistry.
  • Modernizing laboratories to increase student
    appeal.

4
Objectives
  • Postlab Exercises
  • Reinforce educational goals
  • Certify achievement of goals
  • Scoring student performance
  • Prelab Activities
  • Consistent preparation
  • Efficient use of time
  • Accountable

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

10
Educational Aspects
  • Student Survey
  • Yes much
  • More yes than no
  • Somewhat
  • More no than yes
  • Not at all
  • NA

11
Survey Question No or Negative Response Neutral or Positive Response
Help understand experiment? 26 74
Give confidence regarding the experimental procedures? 37 63
Require less assistance from the TA? 41 59
Help perform experiment more efficiently? 39 61
Help understand safety? 16 84
As useful as TAs prelaboratory discussion? 37 63
Preference over TAs prelab discussion? 50 50
12
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 led to high student
    frustration level

13
Future
  • Redesigned the post-laboratory exercises.
  • To include more feedback to student
  • To increase robustness
  • To tighten integration with lab course framework
