This study aims to measure science teachers' perception about their students' practices in science class, and to measure their model of inquiry teaching. The sample consisted of 127 middle school science teachers in Riyadh, Saudi Arabia, 65 males and 62 females, in the school year 2016/2017, and utilized a questionnaire with two parts, 11 items…

Teachers often start their careers in schools with large populations of English language learners (ELLs), whose enrollment in U.S. public schools reached some 4.4 million in 2012 (Kena et al. 2014). To serve these ELLs, new science teachers must develop skills to not only teach the content and language of science but also academic English. Proper…

Teachers' knowledge and application of model play an important role in students' development of modeling ability and scientific literacy. In this study, we investigated Chinese chemistry teachers' knowledge and application of models. Data were collected through test questionnaire and analyzed quantitatively and qualitatively. The result indicated…

This study investigates the beliefs and practices of seven high school chemistry teachers as a result of their participation in a year-long inquiry professional development (PD) project. An analysis of oral interviews, written reflections, and in-class observations were used to determine the extent to which the PD affected the teachers' beliefs…

In this article, the author presents the science and engineering practices from the recently released "A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas" (NRC 2011). The author recognizes the changes implied by the new framework, and eventually a new generation of science education standards will present new…

Despite wave after wave of educational reform in the United States our students continue to lag behind their peers in other industrialized countries on virtually all measures of academic achievement. Effective professional development (PD) is seen as a key to improving instructional practice and therefore student learning, but traditional forms of…

This study examines the impact of standards-based professional development on teacher efficacy and instructional practice of elementary and middle school science teachers. Professional development activities were conducted over a period of 3 years and included content courses as well as teacher involvement in professional learning communities.…

We present a framework for analysing the interplay between context-based teaching material and teachers, and for evaluating the adequacy of the resulting implementation of context-based pedagogy in chemistry classroom practice. The development of the framework is described, including an account of its theoretical foundations. The framework needs…

Understanding frames of reference is critical in describing planetary motion and learning astronomy. Historically, the geocentric and heliocentric models were defended and advocated against each other. Today, there are still many people who do not understand the relationship between the two models. This topic is not adequately treated in astronomy…
