Laboratories have been a cornerstone in teaching and learning across multiple scientific disciplines for more than 100 years. At the collegiate level, science laboratories and their corresponding lectures are often offered as separate courses, and students may not be required to concurrently enroll in both. In this study, we provide evidence that…

We describe efforts toward the development of a hypothetical learning progression (HLP) for the growth of grade 7-14 students' models of the structure, behavior and properties of matter, as it relates to nanoscale science and engineering (NSE). This multi-dimensional HLP, based on empirical research and standards documents, describes how students…

Contextualizing science instruction involves utilizing students' prior knowledge and everyday experiences as a catalyst for understanding challenging science concepts. This study of two middle school science classrooms examined how students utilized the contextualizing aspects of project-based instruction and its relationship to their science…

Considerable effort has been made over the past decade to address the needs of learners in large urban districts through scaleable reform initiatives. We examine the effects of a multifaceted scaling reform that focuses on supporting standards based science teaching in urban middle schools. The effort was one component of a systemic reform effort…

This case study characterizes the inscriptional practices demonstrated by seventh graders, particularly their use of data tables and graphs, in an inquiry-based learning environment. Using a naturalistic approach, we collected multiple sources of data during an 8-month instructional unit that emphasized water quality and relevant concepts. The…

What teaching practices foster inquiry and promote students to learn challenging subject matter in urban schools? Inquiry-based instruction and successful inquiry learning and teaching in project-based science (PBS) were described in previous studies (Brown & Campione, [1990]; Crawford, [1999]; Krajcik, Blumenfeld, Marx, Bass, & Fredricks, [1998];…

A challenge for urban systemic reform initiatives in science education has been to achieve local, state, and national standards for teaching and learning. We have collaborated with teachers in the Detroit Public School System to design project-based curriculum materials that contextualize the learning of science in meaningful real-world problems,…

Science education standards established by American Association for the Advancement of Science (AAAS) and the National Research Council (NRC) urge less emphasis on memorizing scientific facts and more emphasis on students investigating the everyday world and developing deep understanding from their inquiries. These approaches to instruction…

Investigates the depth and accuracy of 6th grade students' content understandings as well as the use of search-and-assess strategies when using on-line resources. Uses scaffolded curriculum materials while completing on-line inquiry units. Concludes that students develop accurate and in-depth understandings if they use search-and-assess strategies…

Investigates how students develop an understanding of chemical representations with the aid of a computer-based visualizing too called eChem that allows them to build molecular models and view multiple representations simultaneously. Involves 11th grade students (n=71) at a small public high school and examines the changes in students'…

Describes a research strategy designed to examine learning and behavior when students interacted with microcomputers and software interfaced with a videotape cassette recorder (VCR). Utilized the VCR to record the video output from the microcomputer and students' verbal comments using a microphone unit. (TW)

From an analysis of 14 secondary student's actions and thought processes, it was found that technology's level of information affected the focus of student observations. The microcomputer group focused primarily on the graph while other groups exhibited multiple foci. The discussion data also reveal that students have three main ideas about how…

Outlines the use of concept maps as a tool for science curriculum development and discusses the changes that occur in the teacher's view of the curriculum with successive revisions of the maps. Describes and analyzes the maps created by sixth-grade teachers. (PR)

Surveys of program graduates of a model science teacher education program were compared with responses from a national sample of exemplary teachers. Results indicated a high degree of similarity between the two groups and provided evidence that a good preservice science teacher education can have a positive effect on the development of preservice…

Describes and examines the effects of the eight-week Summer Science Training Program at the University of Iowa. There was no significant differences between students who had completed high school physics and those who had not on the final course examination, course grade, and attitudes toward physics.
