There is evidence that alienation from science is linked to the dominant discourse practices of science classrooms (cf. Lemke, J. L. (1990). Talking Science: Language, Learning, and Values. Norwood, NJ: Ablex). Yet, in secondary science education it is particularly hard to find evidence of curriculum reform that includes explicit changes in pedagogic discourses to accommodate the needs of stude...

abstract the role of efl lecturers’ first language (l1) in the efl courses has been an ongoing debate. a monolingual approach to efl suggests that the use of the target language solely in foreign language (fl) classroom improves learning of the target language. accordingly, the purpose of the present study was to investigate the attitude of iranian lecturers and efl learners towards using l1 as...

The streamed storage format for sparse matrices showed good performance improvement for sparse matrix and vector multiply (SpMV) compared with compressed sparse row (CSR) and block CSR (BCSR) formats, particularly on IBM Power processors. We extend the format to exploit single instruction multiple data (SIMD) instructions in order to utilize the vector unit, and discuss how the streamed formats...

In streamed graph drawing, a planar graph, G, is given incrementally as a data stream and a straight-line drawing of G must be updated after each new edge is released. To preserve the mental map, changes to the drawing should be minimized after each update, and Binucci et al. show that exponential area is necessary and sufficient for a number of streamed graph drawings for trees if edges are no...

The effects of bilingual education on reading and math achievement were examined by comparing test scores across different elementary-school programs. Results revealed that bilingual Two-Way Immersion programs benefited both minority-language and majority-language students. Minority-language students in Two-Way Immersion outperformed their peers in Transitional Programs of Instruction, while ma...

Preschoolers’ (N 156) classroom language and literacy experiences, defined across multiple dimensions, and their vocabulary and emergent literacy development were investigated. Videotaped classroom observations revealed substantial variability in amount and types of language and emergent literacy activities, across classrooms and for individual children within classrooms. Generally, more time i...

This article investigates the potential benefits of using children’s literature in adult second language (L2) classrooms. A short-term, intensive university course for English reading and writing was designed incorporating children’s literature into the curriculum. The author describes the course and discusses how children’s literature can be used to improve students’ linguistic, cognitive, and...

In Chapter 1 I introduced the principles of CA methodology in relation to ordinary conversation, whereas chapter 2 introduced an institutional discourse perspective. In this chapter I apply these principles and this perspective to the institutional setting of the L2 classroom and to the organisation of turn-taking and sequence in particular. The overall argument of this chapter is that there is...

PURPOSE The potential benefit that a low-cost scripted language and literacy supplemental curriculum titled Read It Again! (RIA; L. M. Justice, A. S. McGinty, A. R. Beckman, & C. R. Kilday, 2006) may have on preschool-age children's skills was explored. RIA was developed to meet the needs of preschool educators who may not have access to current commercially available high-cost language and lit...
