This article considers what might be taught to meet a widely held curriculum aim of students being able to understand research in a discipline. Expertise, which may appear as a "chain of practice," is widely held to be underpinned by networks of understanding. Scientific research expertise is considered from this perspective. Within…

Chemistry teaching has traditionally been weakly connected to everyday life, technology, society, and history and philosophy of science. This article highlights knowledge areas and perspectives needed by the humanistic (and critical-reflexive) chemistry teacher. Different humanistic approaches in chemistry teaching, from simple contextualization…

Formative assessment probes are effective tools for uncovering students' ideas about the various concepts they encounter when learning science. They are used to build a bridge from where the student is in his or her thinking to where he or she needs to be in order to construct and understand the scientific explanation for observed phenomena.…

In this article we provide an example of how to foster an activist-oriented student community by critically examining green technology. We designed this curriculum unit to teach students about the fundamentals of electricity, green technology, and experimental design. Additionally, we viewed this activity as an opportunity for students to apply…

We describe an inquiry-based course in physics and chemistry for preservice K-8 teachers developed at California State University Fullerton. The course is one of three developed primarily to enhance the science content understanding of prospective teachers. The course incorporates a number of innovative instructional strategies and is somewhat…

Engineering design activities can help educators to apply concepts and processes from within and across STEM domains. To facilitate these connections, there is a need for sustained, job-embedded, and collegial professional development that brings together teachers from across STEM domains to engage in design-based activities. These activities can…

More than 400 educators in the Miami-Dade County, Florida, school system take part in a professional-development and curriculum program that attempts to build students' science knowledge while also helping them master English. Developed by researchers at the University of Miami, the Promoting Science among English Language Learners program…

"Primary Science Review's" original "Wobbly Bits" series of articles was born back in 1997, after a conversation about this problem at a meeting of the ASE Primary Committee. The conversation turned to primary science teachers' scientific learning journeys. Each one of them could recount a story where they had completely misunderstood an aspect of…

This paper is concerned with the process of how subject and pedagogic knowledge emerge through teachers' learning in science. It suggests that problematizing subject knowledge through direct experience of learning in science, particularly in those areas that are known to be difficult, constitutes a productive way of turning a deficit model of…

This article describes a field biology course specifically designed for students planning to teach in the elementary or middle-level grades. The fundamental goal of the course is to improve students' science literacy and enhance their ability to apply science concepts in the classroom.

Describes a project undertaken to increase the pedagogical content knowledge of Pakistani science and math teachers (n=31). Presents specific features of the Subject Specialist Teacher Programme in relationship to both the contextual quality and relevance of the initiative. Addresses challenges and possibilities associated with the model as a…

Describes a study of preservice elementary teachers' (n=179) perceptions of geologic time. Finds that the respondents perceived events in Earth's geological past as falling into three distinct clusters: extremely ancient, less ancient, and geologically recent. Finds also that the teachers' grasp of relative time is more secure than their grasp of…

Outlines a program that was designed to be the first step in the development of an academic home for informal science education at the New York University. Aims at taking advantage of nonformal educational resources and bridging the formal and nonformal systems in order to provide people with access to an understanding of science and technology.…

Explores the tension between subject knowledge and pedagogic content knowledge in elementary teacher education by documenting students' and inservice teachers' learning about forces in the context of floating and sinking. Describes significant features of the learning process and examines subject-specific aspects of learning by demonstrating how…

Project TEAM--Teacher Education for the Approaching Millennium--represents an educational partnership designed to improve science teacher preparation, content knowledge among both students and teachers, and the desire to better connect the theoretical constructs offered in a science methods course with the practical concerns expressed by students…
