Higher education is a principal agent for addressing the sustainable development goals proposed by the 2030 Agenda, because of its key mission of knowledge generation, teaching and social innovation for sustainability. In order to achieve this, higher education needs to integrate transversally the values of sustainability in the way of developing the field of management, as well as research, university life and, of course, teaching. This paper focuses on teaching, and more specifically on the didactic strategies considered most relevant for training in sustainability competencies in college students, according to the guidelines commonly accepted by the international academic community. Through collaborative work among experts from six Spanish universities taking part in the EDINSOST project (education and social innovation for sustainability), funded by the Spanish R&D+i Program, in this paper the role of five active learning strategies (service learning, problem-based learning, project-oriented learning, simulation games and case studies) in education for sustainability are reviewed, and a systematic approach of their implementation in higher education settings is presented. The results provide a synthesis of their objectives, foundations, and stages of application (planning, implementation, and learning assessment), which can be used as valuable guidelines for teachers.

Sustainability issues, as unwanted results of not fully respecting natural cycles, are widely recognized as wicked problems, which should not be thought of as problems to be solved, but rather as "conditions" to be managed, as if they were a chronic disease (Seager et al., 2011). There exists a general agreement on the need to reform scientific expertise by developing new ways of knowledge production and decision-making able to cope with the challenges sustainability poses. In this sense, transdisciplinary aspects of sustainability are acknowledged as a transformational stream of sustainability science.Transdisciplinarity is considered a competence for sustainability in technological curriculums. Nevertheless, engineering education professionals tread on unfamiliar ground when entering transdisciplinarity approach, as it includes social sciences and humanities perspectives. Advancing sustainable engineering science requires creating new long-term, participatory, solution-oriented programs as platforms to recognize and engage with the macro-ethical, adaptive and cross-disciplinary challenges embedded in professional issues.Meanwhile, individual university professors and researchers take a step forward to try out innovative experiences in their classrooms to deal with complexity and reach holism in fostering knowledge in different ways. This paper analyses first what is being done and how is it being focused, and second, What are the strategies for and purposes of implementing transdisciplinary experiences in engineering higher education.Assuming that distinct patterns of definition of transdisciplinary exists, the authors collated transdisciplinary initiatives in engineering education for sustainability from Thompson Klein (2014) discourses on transdisciplinarity: transcendence, problem solving and transgression. They also explored how practical constraints imposed by a classroom context, highlighted the limits of transdisciplinarity, and offered suggestions on improvements, which could be implemented. Balsiger (2014) proposes four varieties of transdisciplinarity (soft, hard, inclusive and reflexive) to identify ways for moving from one type to another as circumstances change, in terms of stakeholder's collaboration and knowledge integration possibilities.The methodology consisted in literature review of articles published in relevant journals in the field of sustainability, which focussed on transdisciplinarity approaches in engineering education. We have analysed how the different initiatives fit in Klein's discourses on ACCEPTED MANUSCRIPT transdisciplinarity. Moreover, an affinity analysis has been performed to cluster transdisciplinarity initiatives in engineering education for sustainability in homogeneous groups. Finally, in the varieties of transdisciplinarity framework, the experiences identified when reviewing the literature have been spread over the range among Balsiger's taxonomy.The investigation indicates that most transdisciplinary initiatives in technological education for sustainability ...

Purpose -The purpose of this paper is to analyse the process of changing engineering universities towards sustainable development (SD). It outlines the types of changes needed, both in respect of approaches, visions, philosophies and cultural change, which are crucial for engineering universities which want to implement sustainable development as part of their progammes. Design/methodology/approach -The paper describes various experiences which show how SD education programmes can be implemented at universities, and some of the challenges faced in efforts towards achieving such a goal. It considers the various processes involved and raises some questions which can help to understand how universities, as learning organisations, can engage in the implementation of SD programmes. Findings -The paper has established that engineers have to learn to think long term and position their activities in a pathway towards long-term sustainable solutions. This requires insight into the social environment of engineering as a technology, and the extent to which engineers should know about the intricacies of SD problems. Originality/value -The paper shows that engineers should understand the complexities of the societal setting in which they are developing solutions, and the complexities of making short-term improvements that fit into a long-term SD.

In the 1990s, courses on sustainable development (SD) were introduced in technological universities. After some years of practice, there is increased interest in the evaluation of the most effective ways for teaching SD. This paper introduces the use of conceptual maps as a tool to measure the knowledge acquired by students when taking a Sustainability course. Pilot measurements have been made to evaluate the concepts and their interrelations in order to evaluate the students' learning. These measurements were carried out using a sample of more than 700 European students. To measure the learning outcomes of courses, the evaluation is done twice. Before the course starts, the students' previous knowledge on sustainability is measured; once the students have completed the course they are evaluated again. By comparing conceptual maps drawn by each student, the improvement of the students' knowledge is evaluated. This paper shows the measuring process, and points out the suitability of using conceptual maps for research in education. Moreover, the correlation between the learning outcomes the pedagogical techniques used in each course may indicate the effectiveness of the pedagogical strategies in education for sustainable development.Peer ReviewedPostprint (published version
