Over the past 40 years, Jim Cummins has proposed a number of highly influential theoretical concepts, including the threshold and interdependence hypotheses and the distinction between conversational fluency and academic language proficiency. In this book, he provides a personal account of how these ideas developed and he examines the credibility…

Research on issues concerning the assessment of school-age English language learners (ELLs) in curriculum-learning contexts has been relatively less productive than assessment of adult language learners. A growing demand for assessing school-age ELLs has led to the development of assessment frameworks that provide the opportunity to examine the…

The present paper synthesizes the international research literature on the educational achievement of immigrant and minority language students by articulating three propositions for which there is strong empirical evidence: (a) print access and literacy engagement play a key role in promoting reading comprehension; (b) the development of bilingual…

The state of the art of research in second language acquisition is reviewed. A framework is first established for the examination of second language learning. The concept of proficiency is addressed with respect to its theoretical basis, rating scales, formal tests, and interlanguage studies. The social context of second language acquisition is…

A study was designed to investigate the nature of language proficiency and its cross-lingual dimensions. The focus of the study was on the interdependence hypothesis, that older immigrant students whose first language (L1) cognitive/academic proficiency is better developed on arrival in Canada will acquire English cognitive/academic skills more…

A bilingual education teacher training packet (student's edition) on theories and research concerning bilingual education, second language acquisition, and communicative competence is presented. A theoretical framework for integrating these theories and a theoretical rationale for bilingual education are also presented. In addition to…

A bilingual education teacher training packet (teacher's edition) on theories and research concerning bilingual education, second language acquisition, and communicative competence is presented. A theoretical framework for integrating these theories and a theoretical rationale for bilingual education are also presented. In addition to…

It is argued that cognitive/academic language proficiencies in first and second languages are interdependent and empirically distinguishable from interpersonal communication skills. This analysis is applied to the interpretation of data on the effects of bilingual education programs and on the age issue in second language learning. (PMJ)

The debate over the past decade about the pedagogical effectiveness of bilingual education and the research evidence are reviewed. The case for bilingual education rests on the assumption that because children cannot learn in a language they do not understand, they will fall behind academically in programs taught only in that language. Against…

The existence of a global language proficiency factor is discussed. This factor, cognitive/academic language proficiency (CALP), is directly related to IQ and to other aspects of academic achievement. It accounts for the bulk of reliable variance in a wide variety of language learning measures. Three propositions concerning CALP are reviewed. (1)…

Reviews impact of Canadian French immersion research on theoretical conceptions of bilingualism and biliteracy and identifies four major issues: effects of bilingualism on children's cognitive and academic development; effects of intensity of school exposure to the second language; the "optimal age" issue; and the suitability of a…

One result of the all-time high in population mobility is that in many school systems monolingual and monocultural students are the exception rather than the rule, particularly in urban areas. This shift in demographic realities entails enormous challenges for educators and policymakers. What do teachers need to know in order to teach effectively…
