This study aimed to explore what kinds of epistemological messages were conveyed through teacher discourse in modeling-based and traditional elementary science classrooms and how teachers framed the two classrooms distinctively through these messages. Data came from two sixth-grade teachers' science classrooms--one characterized as a…

Students often learn about measurement uncertainty as an isolated topic, with a focus on generalizable strategies to manage uncertainty in scientific investigation. In this study, we report and analyze a case of emergent learning about measurement and uncertainty, in which students in a Chinese elementary school science class explored and…

Science education reform efforts have emphasized the incorporation of more authentic and meaningful scientific practices into formal learning environments. With this focus on practices, such as scientific modeling, a powerful tool for sense-making and reasoning, comes a need to observe and understand if and how it is actually occurring,…

In this paper, we present a third-grade ecology learning environment that integrates two forms of modeling--embodied modeling and agent-based modeling (ABMs)--through the generation of mathematical representations that are common to both forms of modeling. The term "agent" in the context of ABMs indicates individual computational objects…

Elementary schools are under increasing pressure to teach science and teach it well; yet, research documents that classroom teachers must overcome numerous personal and school-based challenges to teach science effectively at this level, such as access to materials and inadequate instructional time. The elementary science specialist model…

Although the core work of science is oriented toward constructing, revising, applying, and defending models of the natural world, models appear only rarely in school science, and usually only as illustrations, rather than theory building tools. We describe the rationale and structure for a learning progression to understand the development of…

The elementary science teacher educators in this article set recognize the challenges that new science teachers face when they enter classrooms. They have developed frameworks and strategies aimed at helping the preservice teachers with whom they work become "well-started beginners" who are ready to address problems of science teaching. To do so,…

Addresses the current issue of confusion surrounding the widespread use of the term inquiry. Attempts a resolution of the confusion by presenting a model of the processes of scientific inquiry, and proposes that the model's applications can be fruitful for teaching by inquiry. (Editor/JR)

Discusses development and use of an aquatic studies conceptual scheme which has been used in the Project COAST (Coastal, Oceanic and Aquatic Studies) at the University of Delaware. Sample concepts and results from field testing of the curriculum are included. (DH)

Presents a student centered science curriculum model utilizing inquiry strategy and language rich experiences to develop student skills of questioning, thinking, speaking, listening, and reading. (SL)

Investigates the effect of modeling analogy on learning of the concepts of electricity in grade 6, 8, and 10. Describes 2 analogies (train analogy and thermal analogy) with diagrams and examples. Discusses the accessibility, transferability, and difficulty of each analogy. Reports treatment effect and some further implications. (YP)

Lakatos's methodology of scientific research programs is summarized and discussed for Piagetian schools and alternative conceptions movement. Commonalities/differences between these two rival programs are presented along with fundamental assumptions, auxiliary hypotheses, and research policy. Suggests that research findings should not be merely…

Uses examples related to a head of cabbage to discuss: (1) sensory development in children; (2) the integration of sensory and cognitive involvement; and (3) a child's mode of exploring and discovering. Also discusses why science curricula need to be organized around a paradigm that is holistic. (JN)
