Reorienting existing educational programs in technical and vocational education and training (TVET) for the purposes of advancing the attainment of sustainable development goals (SDGs) through skills development significantly depends on the capacity of educators. This capacity can be enhanced through teacher training and professional development programs based on principles of adult learning, as well as through the use of sustainability related resources designed for use in student-centered TVET classrooms. This paper considers how TVET educators respond to the reorientation of the curriculum towards Education for Sustainable Development (ESD) through the inclusion of generic green skills in a green module that was delivered by one TVET institute in Hong Kong. It examines how different types of teachers respond to sustainability related, work-based training conducted through action research. Four teachers’ attitudes are examined, based on their expertise in ESD and their motivation to change current practice. Based on the findings, this paper puts forward a work-based learning model for the professional development of TVET teachers that encourages them to learn with researchers and students together. The model can be adjusted to meet the needs of different types of teachers and it has the potential to enhance teachers’ capacity to implement green modules that will support students’ generic green skills development.
