Teachers’ Perspectives on a Professional Development Intervention to Improve Science Instruction Among English Language Learners

Our 5-year professional development intervention is designed to promote elementary teachers’ knowledge, beliefs, and practices in teaching science, along with English language and mathematics for English Language Learning (ELL) students in urban schools. In this study, we used an end-of-year questionnaire as a primary data source to seek teachers’ perspectives on our intervention during the first year of implementation. Teachers believed that the intervention, including curriculum materials and teacher workshops, effectively promoted students’ science learning, along with English language development and mathematics learning. Teachers highlighted strengths and areas needing improvement in the intervention. Teachers’ perspectives have been incorporated into our on-going intervention efforts and offer insights into features of effective professional development initiatives in improving science achievement for all students.

Urban Elementary Teachers’ Perspectives on Teaching Science to English Language Learners

This descriptive study examined urban elementary school teachers’ perceptions of their science content knowledge, science teaching practices, and support for language development of English language learners. Also examined were teachers’ perceptions of organizational supports and barriers associated with teaching science to nonmainstream students. The study involved 221 third- through fifth-grade teachers from 15 urban elementary schools in a large school district. The teachers completed a survey in the spring of 2005. The internal consistency reliability estimates, Cronbach α, for scales created from the survey items were within an acceptable range. The teachers reported that they were generally knowledgeable about science topics at their grade level and that they taught science to promote students’ understanding and inquiry. In contrast, the teachers reported rarely discussing student diversity in their own teaching or with other teachers at their schools. The teachers identified specific organizational supports and barriers in teaching science with diverse student groups at both the school and classroom levels.

US Urban Elementary Teachers’ Knowledge and Practices in Teaching Science to English Language Learners: Results from the first year of a professional development intervention

The study examined US elementary teachers’ knowledge and practices in four key domains of science instruction with English language learning (ELL) students. The four domains included: (1) teachers’ knowledge of science content, (2) teaching practices to promote scientific understanding, (3) teaching practices to promote scientific inquiry, and (4) teaching practices to support English language development during science instruction. The study was part of a larger five‐year research and development intervention aimed at promoting science and literacy achievement of ELL students in urban elementary schools. It involved 32 third grade, 21 fourth grade, and 17 fifth grade teachers participating in the first‐year implementation of the intervention. Based on teachers’ questionnaire responses and classroom observation ratings, results indicated that (1) teachers’ knowledge and practices were within the bounds of acceptability but short of reform‐oriented practices and (2) grade‐level differences existed, especially between Grades 3 and 5.

A Mile Wide or an Inch Deep? Improving Elementary Preservice Teachers’ Science Content Knowledge Within the Context of a Science Methods Course

Since the beginning of the reform movement in science education, there has been concern that elementary teachers lack the science content knowledge (SCK) needed to engage students in authentic scientific inquiry. This study included 19 preservice elementary teachers and examined the development of their SCK within the context of a uniquely designed elementary science methods course. A project-developed science knowledge test was administered at the beginning and the end of the science methods course, before and after science content was covered concurrent with modeled pedagogy. The preservice elementary teachers had adequate knowledge of low difficulty science content on the pretest, but demonstrated improvement on moderate and difficult science content, especially on topics emphasized in the methods course. Data analyses conducted on change in SCK using analysis of variance were statistically significant and demonstrated a large effect size. Details are discussed, along with large-scale implications and recommendations for elementary science teacher education.

Studying longitudinal change in teacher practices using the multilevel model and latent growth model with an examination of alternative covariance structures

The purpose of this research was to compare results of the multilevel model (MLM) and latent growth model (LGM) for examining change over time. The study came out of the field of education and used data collected from 191 teachers through a professional development intervention in science education. Teachers’ reported use of reform-oriented practices (ROP) was used as the outcome. Change was examined using a piecewise change model and different error covariance structures were examined. Parameter estimates obtained from a model using the error covariance structure commonly assumed in the MLM framework (i.e., random slopes, homogeneous level 1 variance) were nearly identical as were the results of models with various alternative covariance structures commonly associated with the LGM framework. Most of the model fit information was in agreement regarding the best fitting model, with the exception of the standardised root mean square residual (SRMR) fit index.
