A Cartesian conception of material space views each part as external to every other part: "partes extra partes." Because two material things cannot occupy the same space, each of it exists in itself, separated by a boundary from everything else, including other things. This ontology is the origin of thinking the world in terms of…

The link between science education and early childhood education is still blurred. This is so because many science education researchers apparently, but mistakenly, believe that the way young children interrogate and investigate the world around them is not appropriate for their understanding of scientific concepts. Although there is an effort…

As part of a series of investigations in which we explore the integration of verbal and nonverbal aspects of communication into a dialectical, sense-constitutive unit during science lectures, this study adapts the notions of catchments (i.e., repetitions of essential features of the gesture-speech dialectic) and growth points (i.e., moments in…

For many students, the experience with science tends to be alienating and uprooting. In this study, I take up Simone Weil's concepts of "enracinement" (rooting) and "déracinement" (uprooting) to theorize the root of this alienation, the confrontation between children's familiarity with the world and unfamiliar/strange…

The aim of this study is to advance current understanding of the transactional processes that characterize students' sense-making practices when they are confronted with multiple representations of scientific phenomena. Data for the study are derived from a design experiment that involves a technology-rich, inquiry-based sequence of…

Over the past three decades, science educators have accumulated a vast amount of information on conceptions--variously defined as beliefs, ontologies, cognitive structures, mental models, or frameworks--that generally (at least initially) have been derived from interviews about certain topics. During the same time period, cultural studies has…

Inscriptions are central to the practice of science. Previous studies showed, however, that preservice teachers even those with undergraduate degrees in science, generally do not spontaneously produce inscriptions that economically summarize large amounts of data. This study was designed to investigate the production of inscription while a group…

Uses videotaped lectures and interviews to understand lectures in a physics course for prospective elementary teachers. Reports that the professor staged Aristotle, natural philosophy, and students' observations and intuitive knowledge in opposition to Galileo, controlled experiments, and mathematical inscriptions. Concludes that this form of…

This male-specific study examined the development of integrated process skill in the context of open-inquiry laboratory sessions. Findings from this qualitative study indicate that male students develop higher-order process skills through nontraditional laboratory experiences that provided the students with freedom to perform experiments of…

Describes the practice of concept mapping, the student-student and student-teacher interactions, and cognitive activity occurring in participants. Authors conclude that concept mapping is an excellent activity that allows students to engage in extended science discourse. The maps provide students with a means to learn the language patterns of…

Describes the use of Vee maps in helping students understand scientific investigations. (PR)

The use of concept maps, Vee diagrams, flow charts, and productive questions to increase student understanding of laboratory exercises and to improve student attitudes toward lab classes is discussed. Examples of each are provided. Student responses to these teaching methods are described. (CW)

Examines perceptions of eighth graders in a science teaching environment in which they guide their own learning, frame problems for inquiry, design data collection procedures, and interpret and present data in a convincing fashion. Asserts that, in constructing their inquiries, students successfully negotiated courses of action and established…
