Something interesting that I’ve learnt surrounding the subject of our course is BICS and CALS. These BICS and CALS very from student to student and from language learner to language learner. But there are some overall understandings that can help us as teachers.
BICS are a students Basic interpersonal communication skills. To form these skills students need to interact with others in social situations. The language transfer will be in day to day language that one needs to interact with others. On average, these language skills develop after 6 months to two years. Students pick up these skills on the play ground, in the lunch room, while talking on the phone, etc. BICS is just on of the many reasons why, as teachers, we need to push out students to talk to people they would not normally talk to. And we need to assign groups where every student will feel comfortable speaking in English.
CAPS, on the other hand, is a students Cognitive academic language proficiency. This is the formal language that students learn. This comes from listening, reading, writing, and speaking about content based material. For a ELL it usually takes 5 to 7 years to fully develop these skills. 5 to 7 years!! Is is clear that this is a lot longer then it take to acquire BICs. As a result teachers need to find ways of enforcing CAPs in their classrooms and try to find methods that will help their ELLs understand this language more easily.
