The teaching of the Thematic Fields related to the Supply Chain, based on the New Curriculum (CS) in the Vocational High School (Sector of Management and Economy - specialization “Warehouse and Supply Systems” should have as a fundamental methodological principle the effort to increase the active participation of students. The learning outcomes and the skills that, based on the new supply chain management systems, students will be asked to develop will be the starting point for the teaching practice and how it is designed and implemented. The appropriate use of educational activities (indicatively: case studies, small-scale investigations, simulations, role-playing, real data analysis, and decision-making) by teachers can not only enhance students’ efforts to acquire knowledge on the effective organization, coordination, and management of the flow of products and information in the supply chain and to develop skills but also help them to learn autonomously, to cooperate, to communicate. In the context of the new Supply Chain Curriculum, the role of the teacher will change. They will not only be asked to implement, but to plan, experiment, organize, and put information to the test. He/she will also be called upon to create a supportive learning environment, encouraging the active involvement of pupils in individual and group activities and encouraging each pupil to chart his/her learning path. This environment should facilitate a learner-centered approach to knowledge, students’ self-activity, their participation in groups, and the linking of knowledge with everyday knowledge and experience. It should also promote respect, self-esteem, cooperative learning, combining the freedom of speech with the ethics of dialogue, and thus transforming the relationships between pupils and between pupils and teacher into a field of mutual respect, trust, and care, in which each pupil can develop cognitively, emotionally, and morally. The teaching of integrity and corruption issues through the New Curricula in the Supply Chain will enable students, tomorrow's citizens of Greece and the world, to cooperate with Civil Society, face the risks of corruption, and enhance public trust in the processes and public economic and social policies.
