Our study examines the scaffolding strategies employed by secondary biology teachers to support multilingual learners (MLs) in engaging with Science and Engineering Practices (SEPs). Rooted in sociocultural theory, we focus on the integration of academic language in disciplinary practices. Data from video-recorded observations of 12 secondary…

This investigation examined the approaches bilingual education elementary teachers implemented to develop student science and English language understanding. In this investigation, teachers used Proficiency Level Descriptors (PLDs) to assess bilingual-ELs' (BLs) English writing understanding. Teacher interviews, student writing samples, and the…

In this article I present a study on learners' conceptions in cosmology by situating the results in the context of broader historical and sociocultural themes. Participants were community college students in California from non-dominant cultural and linguistic backgrounds finishing their first semester of astronomy. Data were collected through a…

This study sought to investigate the link between preferred learning styles, performance, and cognitive load. After determining learning styles (visual or auditory), undergraduate students were assigned to three instructional formats, namely: Listen Only, Read Only, and Read + Listen. A pretest was administered to assess students' prior knowledge…

In today's schools, many teachers of bilingual learners find teaching science a challenge. Teachers of bilingual learners tend to focus on increasing second-language proficiency and not on science literacy. When second-language development is the target, the development of science literacy can lose priority. This article introduces the framework…

The 2006 National Science Board called for new strategies and instructional materials for teachers to better serve English Learners' (EL) needs. Bilingual Collaborative Online Projects in science were created to assist ELs' construction of science knowledge, facilitate academic English acquisition, and improve science learning. Two bilingual…

A language education professional examines the ways in which constructivism has been applied in the science classroom, and examines several well-known approaches to language teaching that contain elements of constructivism, including the direct method, Total Physical Response, and the Silent Way. Specific ways in which constructivist principles…

This collection of 17 papers relating behavioral science theory to the process of experimental education grew out of a 1963 National Education Association symposium on research in programed instruction. Perspectives and the technology of programing are described in this updated and supplemental successor to the source book, "Teaching Machines…

This book, devoted to issues in science instruction for limited-English-proficient (LEP) college students, examines their specific instructional needs and perspective and suggests alternative teaching strategies. An introductory chapter looks at the changing demographics of American higher education, LEP students' unique academic problems, and…
