As with the responses to the COVID-19 crisis, technology has a critical role to play in enhancing the resiliency of education systems. The urgency of developing responses highlighted the limitations and consequences of a technological solution that is not complemented with supportive policy and investments in capacity for all the actors: decision-makers, teachers, students, and parents/caregivers. In this paper, the authors explore the potential of interactive audio instruction (IAI) as a cost-effective strategy for improving the resiliency of education systems. They begin with a brief historical review of the evolution of IAI followed by a description of the fundamental characteristics of the approach. Prior assessments of the cost-effectiveness of IAI are then reviewed and updated, incorporating new options for development and implementation enabled by the evolution of information and communication technology (ICT). Finally, the authors explore the potential cost effectiveness of IAI as part of a comprehensive strategy to enhance the resiliency of education systems and to promote the continuity of learning for all students.
