Perhaps, the Montessori approach can provide some future insight where this educational pedagogy not only emphasize on the social aspects of children development, but also urge for a prepared and safe learning environment for children. As Children Conducive Learning Environment is getting important especially in the post pandemic era, the COVID-19 is not just a test of health systems, it influences the way children access education, and how safe they feel in schools and communities.
