Several avenues are open to students who wish to study advanced science or mathematics in high school, which include Advanced Placement courses and teacher-designed courses unaffiliated with organized programs. We employ a retrospective cohort study of 4,691 nationally representative college students at 34 randomly selected, colleges and…

Modeling Instruction holds the potential for transforming science instruction and improving student achievement. Key to the success of Modeling Instruction, however, is the fidelity of implementation of its curriculum. This qualitative study examined the impact of Modeling Instruction professional development on participating teachers'…

In this article we describe current educational research underlying a comprehensive model for building a scientific classroom discourse community. We offer a professional development activity for a school-based professional learning community, providing specific science instructional strategies within this interactive teaching model. This design…

With science teachers facing comprehensive curriculum reform that will shape science education for decades to come, high school department chairs represent a critical resource for instructional leadership and teacher support. While the historical literature on the department chair indicates that chairs are in prime positions to provide…

This study investigates a project-based learning (PBL) approach to teaching evolution to inform efforts in teacher preparation. Data analysis of a secondary biology educator teaching evolution through a PBL approach illuminated: (1) active student voice, which allowed students to reflect on their positioning on evolution and consider multiple…

In this paper, we explore how candidates in a graduate-level science teacher preparation cohort attended to the substance of student thinking while watching classroom videos or reviewing students' written work. We shared eight case samples of secondary science classroom work with the teacher candidates (six videos and two collections of student…

The author describes a professional development model for high school science teachers based on the framework of inquiry and science standards. The "Learn-Teach-Assess Inquiry" model focuses on guided inquiry labs as the central theme and builds on these labs to reinforce science concepts and abilities to understand and engage in inquiry in…

The author examines the use of constructivist teaching practices by four new secondary school science teachers (NSTs) from a preparation program with a focus on constructivism. Data of the NSTs is compared to data of secondary school teachers from two different sources: (i) new teachers (NTs) from a broad-scale nationally-funded project involving…

Making chemistry both accessible and interesting to middle and high school students can be difficult. Convincing middle and high school teachers that they will learn something new and applicable from a professional development workshop in chemistry can be equally challenging. This paper describes the use of material science as a means to enhance…

This study sought to examine physics offerings and enrollments, as well as teacher certification data, in small schools (less than 600 students) throughout New York City during the 2004-2005 academic year. Results were then compared to those for mid-sized (600-1200 students) and large (greater than 1200 students) high schools. The following…

Astronomy was a required subject in the first American secondary level schools, the academies of the 18th century. When these were supplanted a century later by public high schools, astronomy still was often required, subsumed into courses of Natural Philosophy. Reasons given at that time to support astronomy as a part of general education include…

This descriptive study investigated whether elementary and middle school teachers in the Central Appalachian region were prepared to teach selected standards-based light, force and motion concepts they could reasonably be expected to teach. The study also sought to compare their preparedness for teaching these concepts. (Contains 7 figures and 7…

The authors describe a Modeling Instruction program that places an emphasis on the construction and application of conceptual models of physical phenomena as a central aspect of learning and doing science. (Contains 1 table.)

Interview data from secondary and postsecondary science instructors explored their in-depth views on preparing students for college science. Professors expressed a high level of consensus concerning two factors: general student skills and mathematics preparation. Teachers, who expressed lower levels of consensus, did agree on the importance of…

The National Research Council's (NRC, 2005) publication "America's Lab Report: Investigations in High School Science" provided the impetus for this study. In the NRC report, the experiences of high school students nationally are described along with recommendations for improving and supporting these experiences. Since the NRC report was published…
