Bilingualism and Second Language Acquisition

Teachers will vary in their understandings of bilingualism and the processes of second language acquisition. Some student teachers will be bilingual or plurilingual themselves and have a wealth of personal experience to draw on. Others may be very familiar with multilingual school environments. Some may have had no contact with bilingual or EAL learners.

In this section we outline aspects of bilingualism and the development of first and additional languages which can inform teachers' approaches to bilingual and EAL learners in schools. Student teachers should, for example, be aware that:

  • The learner’s first or home language plays a significant role in the learning of the additional language in terms of cognitive, linguistic and socio-cultural influences.
  • Learning a second language will not necessarily proceed in an orderly and systematic fashion. Learners will use prior linguistic, learned and world knowledge. They will learn when there is a need to communicate and to learn.
  • Most EAL and bilingual learners will develop a functional level of English in the first two years of schooling in English but they will need continued support to develop the cognitive academic language proficiency necessary for academic success.
  • Bilingual education can be very beneficial in the development of the second language
  • Learning a language and becoming bilingual is also about learning and living in different societies and cultures. It is not just about acquiring a new language, but also about understanding another culture and developing another identity.

The materials in this section provide an introduction to bilingualism and second language acquisition and its implications for the classroom. Most providers include sessions on bilingualism and second language acquisition within their programmes.
