Abstract
This study examines the impact of traditional lectures and guest speaker sessions on developing business communication skills in supply chain education. Focusing on green supply chain management practices (GSCMP) and sustainable development (SD), the research highlights the complementary strengths of these teaching methods. Traditional lectures excel in enhancing written communication and theoretical knowledge, while guest speaker sessions significantly improve verbal communication and practical skills. The findings provide actionable insights for educators to design balanced curricula that align with the dynamic communication needs of modern supply chain management professionals.
