Teaching students how to conduct authentic scientific inquiry is an essential aspect of recent science education reform efforts. Our National Science Foundation-funded GK-12 program paired science graduate students--fellows--with secondary science teachers in order to enhance inquiry-based instruction. This research examined the roles of the…

A WebQuest is an inquiry-based lesson plan that uses the Internet. This article explains what a WebQuest is, shows how to create one, and provides an example. When engaged in a WebQuest, students use technology to experience cooperative learning and discovery learning while honing their research, writing, and presentation skills. It has been found…

This study explores urban secondary teachers' perception of how prepared they are to teach science through inquiry-based strategy. It was conducted against the backdrop of recent calls by the National Research Council (NRC) to restructure the way science is taught. Results described in this paper are based on data collected through a Likert scale…

This paper describes the implementation of an open-ended inquiry experiment for high-school students, based on gas chromatography (GC). The research focuses on identifying the level of questions that students ask during the GC open inquiry laboratory, and it examines whether implementing the advanced inquiry laboratory opens up new directions for…

Because of the limitless knowledge that is literally at your fingertips, the Internet can be an excellent tool for use with gifted students to differentiate curriculum within a general education setting and also in gifted education classes. However, like any tool, its effectiveness depends on how it is used. This article describes six pedagogical…

We investigated for the first time the genetic and environmental aetiology behind scientific achievement in primary school children, with a special focus on possible aetiological differences for boys and girls. For a representative community sample of 2,602 twin pairs assessed at age nine years, scientific achievement in school was rated by…

In this inquiry-based, integrative art and science activity, Grade 5-8 students use multicolored Epsom salt (magnesium sulfate) crystallizing solutions to reveal beautiful, cylindrical, 3-dimensional, needle-shaped structures. Through observations of the crystal art, students analyze factors that contribute to crystal size and formation, compare…

Evaluation reports increasingly document the degree of program implementation, particularly the extent to which programs adhere to prescribed steps and procedures. Many reports are cursory, however, and few, if any, fully portray the long and winding path taken when developing evaluation instruments, particularly observation instruments. In this…

This article articulates how a "grasp of practice" serves as a reasoning resource for inquiry and citizenship abilities associated with nature of science (NOS) understanding. Theoretically, this resource is elaborated through an overlapping concern with "practice" in two literatures, science studies and psychology of learning, bringing attention…

Background/Context: The type of professional development provided for teachers has been undergoing change from a one-time workshop approach to a more embedded, long-term, reflective, and collaborative structure. Although findings on the impact of new forms of professional development (PD) are beginning to emerge in the literature, there is little…

This study was undertaken to gain insights into undergraduate students' understanding of early embryonic development, specifically, how well they comprehend the concepts of volume constancy, cell lineages, body plan axes, and temporal and spatial dimensionality in development. To study student learning, a curriculum was developed incorporating…

This study employed hierarchical linear models (HLM) to investigate Peer-Led Guided Inquiry (PLGI), a teaching practice combining cooperative learning and inquiry and tailored for a large class. Ultimately, the study provided an example of the effective introduction of a reform pedagogical approach in a large class setting. In the narrative, the…

The Oregon 4-H Wildlife Stewards program has been training teachers and volunteers to convert school grounds to education sites by constructing schoolyard wildlife habitats since 1997. The publication "What Can We Learn at the Pond? 4-H Wildlife Stewards Master Leader Guide" (Bourdeau 2004a) was written to support the program's focus on developing…

Whole-class inquiry (WCI) assessments range from challenging, paper-and-pencil puzzles to lab-based problems that require students to apply their own gathered data to a new scenario; the latter might also require students to perform a lab with new parameters, or to answer a question using data from a previous lab. In this article, the authors…

The paper reports on a 3-year study of an experienced fifth grade teacher learning to integrate a Web-based Inquiry Science Environment (WISE) into his core science instruction. Data from this study included videotapes and transcripts of classroom instruction, and audiotapes and transcripts of professional development meetings and interviews…
