ABSTRACT
As the Covid-19 pandemic brought most in-person activities to a halt, radical and visible changes were imposed in all social interactions, including teaching and academic activity in general. This challenging setting tested the education system's capacity to successfully address the Sustainable Development Goals. The success of education for sustainable development (ESD) requires training in the specific skills needed to face the highly emotionally demanding post-pandemic context. In this line, this study focuses on university students' capability to understand and manage emotions, an issue considered to be a key factor in ESD. The aim of this study is to show how students' emotional intelligence influenced their resilience, with repercussions on their engagement and subsequent academic performance. The research model was tested through a questionnaire addressed to 340 students from three different universities during the full lockdown of March-May 2020 as a result of the pandemic. Results show that emotional intelligence was positively related to resilience, which in turn was related to engagement, and consequently, resulted in better academic performance. This finding should spark interest in developing emotional intelligence in education, not only because it produces healthy citizens in the long term, but also because of its short-term positive impacts in the classroom, particularly in such adverse situations as those described here. This study provides a model that links classic variables on educational and positive psychology research with ESD in times of COVID-19.
