The central thesis of this paper is that a cognitively and academically beneficial form of bilingualism can be achieved only on the basis of adequately developed first language (L1) skills. Two hypotheses are formulated and combined to arrive at this position. The “developmental interdependence” hypothesis proposes that the development of competence in a second language (L2) is partially a function of the type of competence already developed in L1 at the time when intensive exposure to L2 begins. The “threshold” hypothesis proposes that there may be threshold levels of linguistic competence which a bilingual child must attain both in order to avoid cognitive disadvantages and allow the potentially beneficial aspects of bilingualism to influence his cognitive and academic functioning. These hypotheses are integrated into a model of bilingual education in which educational outcomes are explained as a function of the interaction between background, child input and educational treatment factors. It is suggest...

The instruction of reading comprehension

Teaching vocabulary to primary grade children is essential. Previous studies of teaching vocabulary (word meanings) using story books in the primary grades reported gains of 20%-25% of word meanings taught. The present studies concern possible influences on word meaning acquisition during instruction (Study 1) and increasing the percentage and number of word meanings acquired (Study 2). Both studies were conducted in a working-class school with approximately 50% English-language learners. The regular classroom teachers worked with their whole classes in these studies. In Study 1, average gains of 12% of word meanings were obtained using repeated reading. Adding word explanations added a 10% gain for a total gain of 22%. Pretesting had no effect on gains. In Study 2, results showed learning of 41% of word meanings taught. At this rate of learning word meanings taught, it would be possible for children to learn 400 word meanings a year if 1,000 word meanings were taught. The feasibility of teaching vocabulary to primary grade children is discussed.

An effective method for building meaning vocabulary in primary grades

Relative efficacy of parent and teacher involvement in a shared-reading intervention for preschool children from low-income backgrounds

In late 1967, Project Follow Through was reorganized to select, test, and evaluate promising but different educational programs for disadvantaged youngsters in the first three grades. Now, nearly ten years later, the completed evaluations of Follow Through suggest that one of these programs, the University of Oregon's Direct Instruction Model, has produced significant gains in measures of positive affect, basic skills, and conceptual reasoning. In this article, Wesley Becker discusses the distinctive features of this model—its underlying assumptions and basic teaching components. He then explores the implications of teaching reading and language skills to economically disadvantaged children and advocates that immediate steps be taken to teach vocabulary systematically throughout the school years. Viewing this goal as essential for compensatory education, he concludes with an analysis of how vocabulary instruction might best be implemented.
