q1 i? The cognitive and social aspects of language proficiency intersect but are not identical or reducible one to the other. → Cummins 1999

q1 · i? · theoretical · r2

This is a conceptual argument in an opinion paper: Cummins reasons that all children acquire their conceptual foundation through home conversational interaction, yet the intersection of cognitive and social aspects does not make them identical. No data are reported for this point.

"This intersection of the cognitive and social aspects of language proficiency, however, does not mean that they are identical or reducible one to the other."

Related Claims¶

• Assuming conversational fluency indicates English proficiency has led to bilingual children being misdiagnosed as learning disabled or retarded and to premature exit from support programs — related
• The BICS-before-CALP sequence is typical for immigrant children but not universal: high L2 CALP can precede fluent L2 BICS in certain situations — related
• L1 and L2 CALP are interdependent: strong promotion of L1 literacy in the early grades entails no adverse consequences for English — related
• Immigrant children acquire peer-appropriate conversational fluency in English within about 2 years but require considerably longer (5-10 years) to catch up academically in English — related
• The Cognitive Model does not address the social aspect of L2 writing and assumes uniform cognitive processes — related
• Reading difficulty occurs when one aspect of the interactive reading process is excluded for an extended period of time — related
• Surface conversational fluency develops within about two years, but academic proficiency in English takes 5-7 years for immigrant students — related
• Critics argue Cummins' framework neglects the sociocultural context and CALP may index acculturation rather than cognitive ability — reports the opposite
• Sociocultural learning theory holds that knowledge develops through engagement in social interaction with others, so English learners benefit from meaningful interaction with peers — related
• Language development functions as a consequence of, not a prerequisite for, deep conceptual exploration in secondary mathematics for English Learners — related
• Bilingual language policy facilitates multilingual and multicultural pedagogical interaction in Indonesian university classrooms — a narrower finding that bears on this claim
• Small-scale studies suggest age 15-16 with intermediate English proficiency (reading GE 5) is a good immigration age — related
