Systematic review of education for sustainable development at an early stage: Cornerstones and pedagogical approaches for teacher professional development

Abstract

During recent decades, education for sustainable development (ESD) has been under the scope of the international community, but research in ESD for early childhood education (ECE) is still scarce. This article proposes a procedural framework for the implementation of teacher professional development opportunities in the area. During the first phase, we undertook a systematic review of peer-reviewed articles on ESD for ECE (n = 30). After an expert committee revision of the articles reviewed, three cornerstones (scientific action-integrated, community-based and value-oriented scopes) and three sets of suitable pedagogical approaches (art-based, outdoor-based and project-problem-based) were identified. The review was enhanced by an unsystematic review of articles (n = 26) that specifically referred to the cornerstones and approaches. Finally, a double-blind expert coding and categorization of the articles (n = 56) was performed in order to validate the results. Focusing on guidelines and approaches, different examples found in the literature are presented. This review offers a useful framework to understand and practice ESD in ECE. Unlike previous reviews, it has a practical scope to foster innovative teacher professional development opportunities, inspire teachers and inform policy makers. We conclude with some common challenges and the needs for educational systems to foster science-based citizenship education towards sustainable development in a practical way, fostering agency from an early stage to transform local context, creating global awareness of the environmental, social and economic challenges of the 21st century.
