This theoretical article proposes using statewide weather-observing networks (Mesonets) to support data-intensive, issue-based teaching of atmospheric topics in middle and high school science. It is argued that the incorporation of this new technology and its affordances into the school curriculum can drastically change the ways that atmospheric…

In this article, we introduce a class of constructionist learning environments that we call "Emergent Systems Sandboxes" ("ESSs"), which have served as a centerpiece of our recent work in developing curriculum to support scalable model-based learning in classroom settings. ESSs are a carefully specified form of virtual…

This paper describes the design and impact of an inquiry-oriented online curriculum that takes advantage of dynamic molecular visualizations to improve students' understanding of chemical reactions. The visualization-enhanced unit uses research-based guidelines following the knowledge integration framework to help students develop coherent…

"PlantingScience" is an award-winning program recognized for its innovation and use of computer-supported scientist mentoring. Science learners work on inquiry-based experiments in their classrooms and communicate asynchronously with practicing plant scientist-mentors about the projects. The purpose of this study was to identify specific…

This study describes the characteristics of pre-service teachers' discourse on a WebCT Bulletin Board in their investigations of local streams in an integrated mathematics and science course. A qualitative analysis of data revealed that the pre-service teachers conducted collaborative discourse in framing their research questions, conducting…

This research addresses the effectiveness of an interactive learning environment, Inquiry Island, as a general-purpose framework for the design of inquiry-based science curricula. We introduce the software as a scaffold designed to support the creation and assessment of inquiry projects, and describe its use in a middle-school genetics unit.…

This case study examines the alignment between the Intended Curriculum, Implemented Curriculum and Achieved Curriculum of a fourth grade inquiry based unit, "Food Chains and Webs." Specifically addressed are how the curriculum was modified to meet state standards, how teachers were trained, and how assessment of curricular implementation was…

The emerging field of urban ecology has the potential to engage urban youth in the practices of scientists by studying a locally relevant environmental problem. To this end, we are developing curriculum modules designed to engage students in learning science through the use of emerging information technology. In this paper, we describe the impact…

This case study of a teacher who engaged his students in inquiry within a technologically rich classroom was conducted over 5 weeks, including 15 regularly scheduled classes. Data include extensive teacher interviews, e-mail, and artifacts such as class notes, curriculum guides, and handouts. A retrospective analysis methodology was utilized to…

This paper reports on a 2-year study designed to investigate the trajectory of change in an urban 5th grade teacher as she introduces science inquiry using the Web-Based Inquiry Science Environment (WISE). Data for this study included videotapes and transcripts of classroom instruction, and audiotapes and transcripts of interviews conducted with…

The science achievement of 226 5th graders from districts that have a kit-based inquiry science curriculum supported by intensive professional development (PD) is compared with data from a group of 173 5th graders from other districts that use nonkit science materials and do not have systematic science PD for teachers. Within the kit-based…
