Environmental insight has emerged as a new scientific concept which incorporates the understanding that the Earth is made up of interworking subsystems and the acceptance that humans must act in harmony with the Earth’s dynamic balanced cycle. This Earth system competency represents the highest level of knowing and understanding in the geosciences community. Humans have an important role as participative beings in the Earth’s subsystems, and they must therefore acknowledge that life on Earth depends on a geoethically responsible management of the Earth system. Yet, the world is far from achieving sustainable development, making the role of the Earth science education in promoting education for sustainability even more relevant. The Earth system approach to education is designed to be an effective learning tool for the development of the innovative concept of environmental insight. Through a holistic view of planet Earth, students realize that humans have the ability to enjoy a sustainable life on our planet while minimising detrimental environmental impacts. There is growing evidence that citizens value science and need to be informed about Earth system problems such as climate change, resource efficiency, pandemics, sustainable use of water resources, and how to protect bio-geodiversity. By moving away from both traditional practices and traditional perceptions, environmental insight and geoethics will lead towards an education for sustainability that provides the citizens of Earth with the tools they need to address the full complexity of its urgent environmental concerns.

Since the beginning of 2020, the coronavirus disease (COVID-19) pandemic has dramatically influenced almost every aspect of human life. Activities requiring human gatherings have either been postponed, canceled, or held completely virtually. To supplement lack of in-person contact, people have increasingly turned to virtual settings online, advantages of which include increased inclusivity and accessibility and a reduced carbon footprint. However, emerging online technologies cannot fully replace in-person scientific events. In-person meetings are not susceptible to poor Internet connectivity problems, and they provide novel opportunities for socialization, creating new collaborations and sharing ideas. To continue such activities, a hybrid model for scientific events could be a solution offering both in-person and virtual components. While participants can freely choose the mode of their participation, virtual meetings would most benefit those who cannot attend in-person due to the limitations. In-person portions of meetings should be organized with full consideration of prevention and safety strategies, including risk assessment and mitigation, venue and environmental sanitation, participant protection and disease prevention, and promoting the hybrid model. This new way of interaction between scholars can be considered as a part of a resilience system, which was neglected previously and should become a part of routine practice in the scientific community.

With the purpose of analysing if case-based teaching methodology could improve higher education students’ knowledge about sustainable development, a quasi-experimental study was conducted in an international project (PASSION—Partnership for Sustainable Development and Social Innovation) and in five countries (Greece, Poland, Portugal and Sweden). Cases were interdisciplinary and focused on sustainable development goals aligned with common worldwide dilemmas like, for example, food consumption, organic farm or nature protection. Our sample consisted of 104 university students aged between 18 and 58 years, where 53% were female. Standardized pre- and post-tests were administered, and a significant improvement in sustainable development knowledge was observed considering three main questions in the pooled dataset (t₁₀₃ = −7.324; p = 0.000). Regarding the four cases applications where results were more significant, an in-depth analysis was conducted, allowing the project team to better understand participants answers to multiple-choice and open questions which are analysed and discussed individually. Our results demonstrate that the case-based teaching improved the knowledge of sustainable development goals, which is expected to induce positive changes in pro-environmental behaviours. We also point out the potential of case-based teaching applied in a cross-country manner. The scheme is particularly valuable in dealing with complex sustainability dilemmas that show better their global perspectives.

Problem-Based Learning, a methodology that builds on problems to develop students’ new knowledge, can also be useful in helping students to learn Nature of Science. Prospective science teachers’ conceptions regarding Nature of Science and its teaching through Problem-Based Learning were analyzed by applying a semi-structured interview. Nine respondents recognized that this methodology promote research activities and contribute to the learning of some aspects of scientific inquiry. Moreover, they specifically considered that Problem-Based Learning may foster the understanding of the tentative nature of scientific knowledge and of the role of creativity implicit in scientific endeavor. Authors consider that more attention should be given to the contemporary Nature of Science views and to its consistent teaching through this methodology
