Although global access to schooling has increased over the last several decades, Sustainable Development Goal 4 (SDG 4), which champions inclusive, equitable, quality education, is far from being achieved. Experts predict that if the global community continues to operate education systems in the same way, by 2030, only one in six countries will reach the universal secondary school completion targets, and approximately 300 million students in school will continue to lack basic numeracy and literacy skills. The 2022 United Nations Transforming Education Summit emphasized the urgent need for a complete overhaul of education systems to meet SDG 4 targets. One significant outcome of the summit was a call to improve student learning by transforming teacher classroom practice. This paper is the first in a series of three working papers meant to serve as references and conversation starters for policymakers and researchers as they navigate pedagogical reform for education system transformation in their local contexts. This paper explores various definitions of pedagogies, the lack of consensus on what pedagogy means in practice, and the effects of Invisible Pedagogical Mindsets on pedagogical approaches.
