Abstract
There is a consensus that the content of education for sustainability should be integrated into the curriculum, engaging students in activities that promote awareness and practice of sustainability. To achieve this goal, it is essential to adopt a student-centered approach that involves creative, stimulating, and challenging activities. This research reports a case study in which 8th grade students had the opportunity to develop these types of activities. Field activities were conducted on a local river combined with a game-based task focused on the role of benthic macroinvertebrates in ecosystems. These activities enabled collaborative learning and the social construction of knowledge, which are pivotal for more sustainable education. It should be noted that students learned how to collect, observe, describe, organize, and classify species to make inferences about water quality. The main issue we intended to address was how to improve and integrate scientific activities into the students’ curriculum to foster a more sustainable education. The specific research questions were put forward: a) Do the implemented activities instigate collaboration for a more sustainable education? b) Do the implemented activities increase scientific curiosity and develop critical thinking and attitudes? c) Do the implemented activities increase students’ knowledge concerning aquatic resources, such as benthic invertebrates? The results confirmed the important role of student-centred activities, in this particular case fieldwork and game-based tasks, in the development of knowledge and scientific thinking skills, which could be scaffolded through feedback, rewards and flow states. This study provides a more holistic perception of local river ecosystems, their role in improving environmental attitudes, and promoting a more sustainable science education.
