Academic language is critical for English learners (ELs) to succeed in the science classroom. This study analyzed the instructional practices centered around academic language taking place in eight, fifth-grade classrooms during a grant-funded project. Observational data collected through a classroom observation instrument were analyzed to describe and compare the instructional practices occurring in treatment and control classrooms when teachers and students used academic language. Our findings show both treatment and control classrooms using academic language during the course of the intervention study, but the instruction looked markedly different in each setting. These differences provide valuable insight for practitioners and researchers concerned with the academic language development of ELs in science classrooms.  相似文献

ABSTRACT

Research in the United States show that professional learning (PL) can improve classroom instruction. However, teachers, especially educators in the content areas, receive insufficient training specific to meeting the language and academic needs of English learners (ELs). The purpose of the current randomized controlled trial (RCT) study was to introduce a high-quality PL program for supporting middle school teachers in teaching science to ELs through classroom observations, so as to evaluate whether in-service science teachers’ instructional delivery can be shaped by intensive, structured, and ongoing PL. Results indicated that after receiving PL, treatment teachers allocated a significantly higher portion of their instructional time in teaching content language, developing students’ expressive language skills, small group and pair activities, implementing strategies evidenced to effective with ELs, and providing more opportunities for students to participate in hands-on activities that were content-related and grade-appropriate. Practical implications for PL were discussed for an international audience.  相似文献

The purpose of this study was to compare and describe 8 fifth-grade classrooms by their teachers pedagogy during a quasiexperimental, longitudinal, and field-based project focused on increasing English language learners' (ELLs') achievement in science and language. The larger study found statistically significant and positive intervention effects in favor of the treatment group on measures of science and language achievement. This study adds an in-depth analysis of the teacher pedagogical practices contributing to students' science and language achievement as captured by an observational instrument used during the project. Results from the analysis show how treatment teachers, when compared to control teachers, focused on activities promoting verbal and written interaction among the students and dense cognitive language use during science inquiry instruction. The findings support the importance of effectively using language in the science classroom to improve ELLs' science and language achievement. Implications for future research and practice are discussed.  相似文献

We present the development and validation of a science notebook rubric intended to measure the academic language and conceptual understanding of non-mainstream students, specifically fifth-grade male and female economically disadvantaged Hispanic English language learner (ELL) and African-American or Hispanic native English-speaking students. The science notebook rubric is based on two main constructs: academic language and conceptual understanding. The constructs are grounded in second-language acquisition theory and theories of writing and conceptual understanding. We established content validity and calculated reliability measures using G theory and percent agreement (for comparison) with a sample of approximately 144 unique science notebook entries and 432 data points. Results reveal sufficient reliability estimates, indicating that the instrument is promising for use in future research studies including science notebooks in classrooms with populations of economically disadvantaged Hispanic ELL and African-American or Hispanic native English-speaking students.  相似文献

In this longitudinal study, the cross-language transfer from second language (L2) to first language (L1) was examined among Spanish-speaking English-language learners in an English intervention (Grades 1–3) in the southwest United States. Path analysis revealed statistically significant transfers (ps < .05) for the treatment group from English reading comprehension to Spanish reading comprehension. English vocabulary and English grammar also had an indirect influence on Spanish reading comprehension through English reading comprehension. For the comparison group, no English to Spanish paths were statistically significant. We concluded that intervention activities in L2 influenced L1 reading even when L1 instructional time was reduced.  相似文献

The authors of this quantitative study measured and compared the academic language development and conceptual understanding of fifth-grade economically disadvantaged English language learners (ELL), former ELLs, and native English-speaking (ES) students as reflected in their science notebook scores. Using an instrument they developed, the authors quantified the student notebook language and concept scores. They compared language growth over time across three time points: beginning, middle, and end of the school year and across language-status (ELL, former ELL, and ES), and gender using mixed between-within subjects analysis of variance (ANOVA). The authors also compared students’ conceptual understanding scores across categories in three domains using ANOVA. Students demonstrated statistically significant growth over time in their academic language as reflected by science notebook scores, and we noticed conceptual trends in which scores for ELLs, former ELLs, and male students lagged behind at first, but caught up to their peers by the end of the school year.  相似文献

Despite research interest in testing the effects of literacy-infused science interventions in different contexts, research exploring the relationship, if any, between academic language and conceptual understanding is scant. What little research exists does not include English language learners (ELLs) and/or economically disadvantaged (ED) student samples—students most at risk academically. This study quantitatively determined if there exists a relationship, and if so, how strong of a relationship, between ELL and ED students’ academic language and conceptual understanding based on science notebook scores used in a larger science and literacy-infused intervention with a sample of culturally diverse students. The study also considered strengths of relationships between language and concept science notebook scores within student language status groups (ELL, former ELL, and English speaking). Correlational analyses noted positive, large, and significant correlations between students’ language and concept scores overall, with the largest correlations for science notebook entries using more academic language. Large correlations also existed for ELL student entries at the end of the school year. Implications of the findings for future research and practice in science classrooms including literacy interventions, such as science notebooks, with populations of culturally diverse students are discussed.

This study describes the development of a learning process of genetic counseling and basic genetics using an e-learning model and its application to a group of psychologists in the state of Parana in southern Brazil. The aim was to analyze the impact on the increase of knowledge in the presented subjects and the possibility of applying this project on a larger scale. The results of two observations were compared. The observations consisted of scores on the same exams, applied before and after taking the course. Results indicated that the remote education process is indeed a viable alternative for genetic counseling education and is validated for application in large scale together with Centers for Family Health Care Assistance of the Brazilian Ministry of Health Care.  相似文献
