The theme of CIES asks our society of academics and practitioners to confront the ways in which education is a space of debate and contestation, and how stakeholders both internal and external to education systems seek to effect change (or maintain the status quo). The behavioral science perspective is not new to international education. It has often been presented from different research perspectives, including teacher mental models of teacher beliefs (Saberwal et. al., 2018), and the social aspects of educational change (Fullan, 2015). However, recent interest has shifted focus on the understanding of education systems change using a behavioral science lens (Ajani 2022). This perspective is important as education systems programming is frequently designed without a true understanding of how individuals will respond to change (Jeevan and Hwa, 2022). The presentations present studies which examine teachers, caregivers, and instructional practice and change within an education system. What new insights do we have and how might they influence policy and implementation for education systems change? This deck includes the following presentations and authors: From access to learning to nudging: Why behavioral science might be the next new best thing in education improvement programs (Amber Gove, RTI International), More of this and less of that: How a behavioral science lens suggests alternative approaches to education program design & implementation (Simon King, Creative Associates), Peer-to-Peer Learning: The Power of Social Networks in Adoption of New Pedagogies (Elizabeth Marsden, RTI International), and Supporting Caregivers of Young Children in South Africa to Engage in Play (Carolina Better, Ideas42).
