Nirantar develops alternative teaching-learning packages. Our material on health (Swasthya ki Khoj Mein) and Hindi language teaching (Bolti Hai Bhasha), which can be transacted with non-literate and semi-literate women and adolescent girls, has been used extensively by grassroots and education programmes. Field interactions are an essential part of developing the modules so that their efficacy is tested in the very process of creation.
