Answer 2

Globally, there are 50-75 million ‘marginalized’ children who are not enrolled in school. Children whose primary language is not the language of instruction in school are more likely to drop out of school or fail in early grades. Research has shown that children’s first language is the optimal language for literacy and learning throughout primary school (UNESCO, 2008a). In spite of growing evidence and parent demand, many educational systems around the world insist on exclusive use of one or sometimes several privileged languages. This means excluding other languages and with them the children who speak them (Arnold, Bartlett, Gowani, & Merali, 2006).
