Schools require not only good use of English but also model teachers who are able to guide and motivate their students to master the language
. By being interested in their students and in teaching , language learning is profoundly influenced by one's social environment. This environment comprises at least four groups of participants : ( a ) the student's peer groups in and out of the school; ( b ) the adults with whom students interact; ( c ) the student's home environment; and ( d ) the wider socio-cultural sphere, largely influenced by the media. Nonetheless, what seems under-emphasized is the fact that building English language proficiency demands far more than the dedicated efforts of English teachers, native or non-native. English language lessons occupy only a fraction of total curriculum time, so students are significantly exposed to similar or competing models of languages in other classes.
