Explain what is separate underlying proficiency model
The Separate Underlying Proficiency Model is a theoretical framework used to understand the development of bilingualism in individuals. It suggests that when a person becomes proficient in two languages, they have separate underlying proficiency in each language.
According to this model, each language is represented by its own set of skills, knowledge, and abilities. These abilities include vocabulary, grammar, pronunciation, and cultural understanding. The model proposes that a person's proficiency in one language does not directly affect their proficiency in the other language.
This framework is in contrast to other models, such as the Common Underlying Proficiency Model, which suggests that there is a shared underlying language proficiency that contributes to the development of both languages in a bilingual individual.
The Separate Underlying Proficiency Model emphasizes that there may be variations in the proficiency levels of each language. For example, a person may be more fluent in one language than the other, or they may have stronger reading skills in one language but better speaking skills in the other.
This model has implications for language acquisition and education. It suggests that each language should be taught and developed separately, rather than assuming that skills learned in one language will automatically transfer to the other language. It also acknowledges that proficiency in each language can be influenced by various factors, such as exposure, environment, and personal motivation.
Overall, the Separate Underlying Proficiency Model provides a framework for understanding the unique development and proficiency levels of each language in bilingual individuals.
