The "Next Generation Science Standards" ("NGSS"), due to be released this spring, represents a revolutionary step toward establishing modern, national K-12 science education standards. Based on the recommendations of the National Research Council's "A Framework for K-12 Science Education: Practices, Crosscutting…

This longitudinal study examined the extent to which teachers' participation in a 3-year professional development program enhanced their self-efficacy and prompted changes in science instruction in the early elementary grades. The study used a mixed-methods design, and included 39 teachers who taught in kindergarten, first grade, or second…

English learners are faced with the dual challenge of acquiring English while learning academic content through the medium of the new language (Lee et al. in "J Res Sci Teach" 45(6):726-747, 2008; Stoddart et al. in "J Res Sci Teach" 39(8):664-687, 2002) and therefore need specific accommodations to achieve in both English and the content areas.…

This study investigated the extent to which teacher professional development led to changes in science instruction in K-2 classrooms in rural school districts.

This study explores how elementary teachers perceive and use "engaging oral strategies" (i.e., manners of speaking that encourage students to participate and become engaged in science discussions). It is reported that the strategies employed as well as their frequency varied substantially depending upon on the teachers' grade level and…

In this study we described an action research project enacted by a veteran Kindergarten teacher (Sarah) in the context of a professional development program. Over the course of a year, Sarah collaborated with other teachers in a small group to investigate how to use "Science Talks" to promote student learning in Kindergarten classrooms. A…

To ensure that all students have sufficient knowledge and skills in science and technology for success in the 21st century, the nation must attract, prepare, and retain well-educated, effective preK-12 science teachers. The National Science Teachers Association (NSTA) considers strong, performance-based science teacher education program and…

This case study of a midwestern school district's reform effort explored the treatment fidelity of the Science: Parents, Activities, and Literature (Science PALs) project. Data were collected from the perspectives of three stakeholders: students, school district, and parents. Students' and school district supervisor's perceptions indicated that…
