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…

Given the prevalence of bullying in schools, it is imperative that preservice secondary science teachers (PSSTs) know how to deal with this issue in the classroom. This is especially important in science, as the content covered in classes can sometimes lead to discussions of race, religion, and sexual orientation, which can be sensitive topics. In…

Prior research suggests that students' understanding of scientific concepts is pre-determined by their reasoning ability. Other efforts suggest that American students' scientific literacy is in decline. One difficulty Bybee (2009) acknowledges is that there are two divergent philosophical models of scientific literacy. The first describes the…

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…

A survey of 6th-12th grade students was conducted to measure their science-related attitudes and interests. Significant gender differences were found among these students. Females reported more anxiety about science as well as less motivation in and enjoyment of science than males. In spite of their unfavorable attitudes toward science, a large…

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…

Teaching science through inquiry-based, student-centered instructional methods has been consistently emphasized by science education reform documents such as the National Research Council's (NRC) "National Science Education Standards" (NSES), and practically all states have adopted inquiry standards. In order for science education reforms to…

Despite the long history of the study of pedagogical content knowledge (PCK), two facts remain obvious. First, there are almost as many conceptions regarding the definition of PCK as there are researchers interested in it. Second, it is largely unclear which methods enable teacher educators to best prepare teacher candidates to use PCK. Recently,…

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.)
