This learning resource focuses on the ethical implications of corporate sourcing decisions in the context of the LuminaTech case study. It encourages students to evaluate options between low-cost sourcing and ethical sourcing through the principles of Corporate Social Responsibility (CSR) and Global Labor Standards. The resource includes a structured argumentation framework guiding students to form claims, provide evidence, and explain their reasoning during a Socratic debate. Additionally, it incorporates practical activities like observation routines and metacognitive calibration to foster engagement and critical thinking about the consumer-labor relationship and the responsibilities corporate entities hold towards labor standards.
