the packaging lab
The Packaging Lab
  • Administered at the beginning of the quarter and a component of the final exam.
  • Students examine 4 packaged products.
  • Can of tomatoes
  • Box of tea bags
  • Carton of eggs
  • Packaged Goldfish crackers
  • Students are asked to rank (best-worst) which packaging is most sustainable.
  • Students must support their claim by stating:
    • Attributes and Decision Criteria
    • What else you need to know
  • Repeat process within a group and re-rank packages.

The Packaging Lab Cont’d
  • The packaging lab is used as a diagnostic tool to assess the students understanding of LCA concepts.
  • PRE/POST
    • Pre was the initial lab exercise. Students not expected to have high scores.
    • Post is administered in the final exam. Look for a change in scores.
  • Goal: Learn how to streamline assessment process

Each box is determined to have a “qualified”, “partially qualified”, or “unqualified” answer. All responses recorded in database.

breadth depth for lca important
Breadth/Depth for LCA = important
  • Student responses were categorized as being more or less sophisticated (also “depth”)
  • What does this mean & how did we score?
    • Qualified, Partially Qualified, Unqualified Recyclable>> energy intensive to recycle >> fossil fuel from the middle east used to recycle.
    • Specificity within a theme: breaking down phases of LCA
    • Awareness of contingencies (ex. Package is reusable if taken care of by consumer.
    • Not treating the package as a unified whole, but recognizing that different components have different implications (ex. Plastic bottle cap is made a different plastic than bottle).
scoring rubric breadth vs depth
Scoring Rubric- Breadth vs. Depth
  • Breadth Categories: determined by researched phases of LCA.
    • 6 breadth categories in BOLD. Depth follows breadth-category.
      • Source: Finite or renewable, rare accessible, energy needed.
      • Processing: Extraction, manufacturing & production.
      • Transportation: includes pre-production shipping & post-production distribution.
      • Design & Quality: aesthetics, functionality/design, & durability.
      • By-Products & Externalities: damage to ecosystems, toxicity, health, & welfare.
      • End-of-Life & Recycling: where does it physically end up, in what state, & inputs.

results by point threshold for pre
Results by Point Threshold for Pre

Each student had a number of responses in each level of sophistication. We set thresholds to show what percentage of their responses were in the respective qualifiers. The three thresholds were 0-25%, 37.5-50%, and 62.5-100%.
