There are two major aspects of language proficiency that must be acquired by second language learners. Jim Cummins has identified these as Basic Interpersonal Communication Skills (BICS), or conversational proficiency, and Cognitive Academic Language Proficiency (CALP), or academic proficiency.BICS:BICS stands for Basic Interpersonal Communication Skills. These language skills are needed in social situations.It refers to the language that is necessary for day-to-day living, including conversations with friends, and informal interactions. For example, the language used in the playground, on the phone, or to interact socially with other people.It is context embedded. Context embedded means that the conversation is often face-to-face, and offers many cues to the listener such as facial expressions, gestures, and concrete objects of reference. It is a cognitively undemanding language, i.e. it is easy to understand, deals with everyday language and occurrences, and uses a simple language structure.Hence, it is clear that the language used in the playground, on the phone, or to interact socially with other people is part of Basic Interpersonal Communication Skills (BICS).Hint CALP stands for 'Cognitively Advanced Language Proficiency'. It refers to the idea of developing second language skills is essential for academic learning. CALP refers to formal academic learning. It includes listening, speaking, reading, and writing about subject area content material.Group Discussion is the most important factor for effective language class learners as the discussion is a teaching methodology that facilitates meaningful learning by emphasizing upon sharing ideas and experiences with peers and teachers.Discourse studies larger chunks of language as they flow together. It can also be defined as an analysis of speech units larger than the sentence and of their relationship to the contexts in which they are used.
