1 Ben Oberhand B.A. Environmental Studies, UCSC 2012 Tamara Ball, Ph.D. Post Doctoral Researcher James Barba B.A. Politics and Legal Studies, UCSC 2012 Student Assessment for Sustainable Design

2 The Packaging Lab Administered at the beginning of the quarter and a component of the final exam. Students examine 4 packaged products. 1. Can of tomatoes 2. Box of tea bags 3. Carton of eggs 4. Packaged Goldfish crackers Students are asked to rank (best-worst) which packaging is most sustainable. Students must support their claim by stating: 1. Attributes and Decision Criteria 2. What else you need to know Repeat process within a group and re-rank packages.

3 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

4 Image of exam Goldfish Tea Box Egg Carton Tomato Can Each box is determined to have a “qualified”, “partially qualified”, or “unqualified” answer. All responses recorded in database.

5 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? A. Qualified, Partially Qualified, Unqualified Recyclable >> energy intensive to recycle >> fossil fuel from the middle east used to recycle. B. Specificity within a theme: breaking down phases of LCA C. Awareness of contingencies (ex. Package is reusable if taken care of by consumer. D. 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).

6 Scoring Rubric- Breadth vs. Depth Breadth Categories: determined by researched phases of LCA. 6 breadth categories in BOLD. Depth follows breadth-category. 1. Source: Finite or renewable, rare accessible, energy needed. 2. Processing: Extraction, manufacturing & production. 3. Transportation: includes pre-production shipping & post-production distribution. 4. Design & Quality: aesthetics, functionality/design, & durability. 5. By-Products & Externalities: damage to ecosystems, toxicity, health, & welfare. 6. End-of-Life & Recycling: where does it physically end up, in what state, & inputs.

7 Low level Responses Indicated in RED Topics Source 2.Processing 3.Transportation 4.Design & Quality 5.By-Products & Externalities 6.End-of-Life

8 Topics Source 2.Processing 3.Transportation 4.Design & Quality 5.By-Products & Externalities 6.End-of-Life

9 High Level Responses Indicated in GREEN Topics Source 2.Processing 3.Transportation 4.Design & Quality 5.By-Products & Externalities 6.End-of-Life

10 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%, %, and %.

11 Results by Point Threshold for Post Each student had a number of responses in each qualifier. We set thresholds to show what percentage of their responses were in the respective qualifiers. The three thresholds were 0-25%, %, and %.
