Lecturing is an important aspect of the culture of science education. Perhaps because of the negative associations constructivist educators make with lecturing, little research has been done concerning the generally invisible aspects of the (embodied, lived) "work" that is required. Traditional research on science lectures focuses on…

Science educators often suggest that students should learn science in ways and settings that bear family resemblance with "the real thing." Internship in science laboratories constitutes one such way in which students may learn science and learn about science. However, very little is known about "how" participants experience a…

Studied analogy generation and development and analogical reasoning with 25 German tenth graders in a physics class. Results show the advantages and disadvantages of using analogies in promoting conceptual change and as a teaching technique. (SLD)

Few studies have focused on understanding how teaching and learning in classrooms are mediated by other dimensions of the organizational systems of which education is an integral part. Our 7-year ethnographic study of an urban high school shows how time and temporality constitute key practical and theoretical resources to the actors in the…

A study of the processes by which 24 grade-12 Australian physics students brought order to their observations and practices shows that the phenomena students construct from their laboratory work (not always accurate) develop from connections among the embodied practices of language and physical action, their world, and social relations. (SLD)

Discusses a study designed to understand 11th-grade students' learning during conversations with their teacher over and about a computer-based Newtonian microworld, Interactive Physics. Illustrates that students' learning was not local but persistent, in that they used appropriate canonical science talk without teacher support. (36 references)…

Examines inscriptions in texts usually available to students in high school and undergraduate science courses in course textbooks and journal articles. Reports on the differences existing in the frequency of different types of inscriptions that appear unrelated to the interpretive competencies of the students for whom they are intended. (Contains…

Among the conclusions from an microanalysis of 29 high school physics student's concept mapping behaviors were that concept maps lead to sustained discourse on the topic and improved declarative knowledge. On the negative side, concept maps let scientifically incorrect notions become ingrained and go unchallenged. (PR)

Photographs are a major aspect of high school science textbooks, which dominate classroom approaches to teaching and learning. It is thus surprising that the function of photographs and their relation to captions and texts have not been the topic of analysis. The purpose of this study was to investigate the prevalence, function, and structure of…

A study involving 42 students enrolled in a physics course was conducted to document students' epistemologies and their concurrent views about knowing and learning. Analyses revealed a spectrum of epistemological commitments commensurable with positions from objectivism to relativism. Implications to classroom environment are discussed. (ZWH)

Illustrates how a well-designed curriculum can lead students to construct an unwanted conception. Concludes that the conceptual-change-cum-discourse perspective has the potential to integrate the affordances of both methodological approaches and past empirical accomplishments. Contains 33 references. (DDR)

Reports on a study of a physics class in which few interactions occur among students. Concludes, through observations and interviews. that students describe both the social and physical world in different ways. Contains 33 references. (DDR)

Presents a study that analyzes an extensive database consisting of the written and oral discourse of students (N=23) as they described their thoughts on ontology, epistemology, and sociology of scientific knowledge. Contains 51 references. (DDR)

Investigates the practices required for reading graphs in high school textbooks and scientific journals. Discusses the role of high school textbooks in the appropriation of authentic scientific graph-related practices. Finds that scientific journals provide more resources to facilitate graph reading and feature more elaborate descriptions and…

Presents a study involving students (n=46) enrolled in an introductory physics course designed to describe and understand students' experimenting and problem-solving strategies in a constructivist learning environment. Concludes that students should be provided with problem-rich learning environments in which they learn to investigate phenomena of…
