Choosing the most appropriate method of teaching sustainable development using hybrid algorithm of DEMATEL-ANP and TOPSIS in fuzzy approach (A case study of technical and vocational schools (

Development of industry, agriculture and services, requires training of efficient workforce in technical and vocational fields. Knowing that human activity in these three sectors decreases the environmental quality, dealing with environmental degradation can be achieved by implementing long-term sustainable development education policies. The present study is an applied research and aims to choose the best method for sustainable development education. For this purpose, first, the sustainable development competency criteria for technical and vocational graduates were identified by library studies and three different questionnaires were designed based on them. Then, DEMATEL Technique was used to identify the mutual interactions among the criteria. The obtained results were used for designing a network structure on the fuzzy ANP technique to assign weight to each criterion. Finally, the obtained weights were used to rank and select the best method for sustainable development education based on the TOPSIS technique. Since these techniques cannot resolve the ambiguity and uncertainty of verbal evaluations, the fuzzy triangular numbers were used in all the above-mentioned techniques. The results obtained in this study indicate that self-learning skills and proficiency in the environmental knowledge related to a particular technical and vocational field is the most important sub-criteria of sustainable development competence. Furthermore, group discussions were found to be the most appropriate teaching method for sustainable development education. Due to the importance of sustainable development competence criteria in choosing the right method for sustainable development education, it is necessary to consider all aspects of knowledge, skills, attitude, development and growth, in order to strengthen the environmental attitude and behavior.
