Cummins theorized that there are two kinds of English proficiency the English Second Language students must learn. The ability to converse with others and to articulate needs in Level2, and can be developed only 2-3 years. The other is Cognitive Academic Language Proficiency. Cognitive Academic Language Proficiency involves the acquisition of academic literacy skill, and the use of Level2 to understand complex, decontextualized linguistic structures, and to analyze , explore and deconstruct the concepts presented in academic texts. It takes between 5-7 years to master Cognitive Academic Language Proficiency. Cummins argues that English Second Language learners cannot acquire cognitive academic language skills from everyday conversation. Developing these cognitive skills requires task-based, experiential learning typified by learners’ interactions with contexts, task, and text that present them with complex interdisciplinary context. Thus, Cummin’s model provides another theoretical foundation for Content Based Instruction in English language Learning.
