Why Do We Teach Labs?
What Are Our Goals In Teaching Organic Chemistry Labs?
The Traditional Teaching Goals
Higher-Order Traditional Goals
Traditional or Verification Experiments
Confirmation of knowledge students already have
Cosmic futility – make a white powder, prove it’s what you expect, and donate it to chemical waste, again, and again, and again
Guided-Inquiry or Discovery Experiments/Projects
Question or purpose driven
Outcome not known but the chemistry builds on what the students know
A procedure is given
The experimental results must be evaluated and conclusions drawn
Open-ended Inquiry Experiments/Projects
Students generate their own procedure
Guided-Inquiry Grignard ProjectPurpose: To design and carry out the Grignard synthesis of a secondary or tertiary alcohol from a simpler primary alcohol
Guided-inquiry experiments and projects are effective
