This Environmental/Ecological Economics course is using a project based learning case study approach. Students form teams and select Environmental Justice case studies of their own interest. We start with well studied set of case studies from an EU CEECEC consortium that matched NGOs with researchers and published for educational purposes "Ecological Economics from the Ground Up" with what is now an online glossary with citations. Students learn sustainability and ecological economics conceptual knowledge through real life examples. Students learn professional sustainability competencies by identifying stakeholders and their interests, and project evaluation. Students update the case studies in the CEECEC set and map with the Sustainable Development Goals. Student teams make updates to Wikipedia, if warranted. The second phase of the course involves teams selecting a case study from the crowd sourced Environmental Justice Altlas, EJatlas.org and conduct research to add sources, fill gaps, and use the case study to teach others about Ecological Economics. Teams will also find associated incomplete Wikipedia entries to fill gaps and add sources. In some cases, students may draw upon Wikipedia entries in other languages.
