John M. Reveles Gregory J. Kelly Richard P. Durán 《Cultural Studies of Science Education》2007,1(3):467-495
This ethnographic study of a third grade classroom examined elementary school science learning as a sociocultural accomplishment.
The research focused on how a teacher helped his students acquire psychological tools for learning to think and engage in
scientific practices as locally defined. Analyses of classroom discourse examined both how the teacher used mediational strategies
to frame disciplinary knowledge in science as well as how students internalized and appropriated ways of knowing in science.
The study documented and analyzed how students came to appropriate scientific knowledge as their own in an ongoing manner
tied to their identities as student scientists. Implications for sociocultural theory in science education research are discussed.
John Reveles is an assistant professor in the Elementary Education Department at California State University, Northridge. He received
his Ph.D. from the University of California, Santa Barbara in 2005. Before pursuing his Ph.D., he worked as a bilingual elementary
school teacher for 3 years. His research focuses on the development of scientific literacy in elementary school settings;
sociocultural influences on students' academic identity; equity of access issues in science education; qualitative and quantitative
research methods. Within the Michael D. Eisner College of Education, he teaches elementary science curriculum methods courses,
graduate science education seminars, and graduate research courses.
Gregory Kelly is a professor of science education at Penn State University. He is a former Peace Corps Volunteer and physics teacher. He
received his Ph.D. from Cornell in 1994. His research focuses on classroom discourse, epistemology, and science learning.
This work has been supported by grants from Spencer Foundation, National Science Foundation, and the National Academy of Education.
He teaches courses concerning the uses of history, philosophy, sociology of science in science teaching and teaching and learning
science in secondary schools. He is editor of the journal Science Education.
Richard Durán is a Professor in the Gevirtz Graduate School of Education, University of California, Santa Barbara. His research and publications
have been in the areas of literacy and assessment of English Language Learners and Latino students. He has also conducted
research on after school computer clubs, technology and learning as part of the international UC Links Network. With support
from the Kellogg Foundation, he is implementing and investigating community and family-centered intervention programs serving
the educational progress of Latino students in the middle and high school grades. 相似文献

Pedro Gutiérrez Bueno wrote two editions of a chemistry textbook between 1788 and 1802. The paper offers a comparative view
of both editions taking into account Gutiérrez Bueno’s biography, his intended audience and the changes related to the so-called
chemical revolution. Some conclusions are at odds with common images about scientific revolutions and the role of textbooks
in science. The analysis aims to shed some light on the multiple historical forces shaping textbooks and the way in which
scientific change is assimilated by their writers.

In this work, we presented an analysis of the representation of the special relativity theory (SRT) in the most used texts
in high school, Polimodal level and university level in the teaching in the Argentine Republic, from a historic, epistemological
and didactic perspective. The results show that none of the analyzed texts would allow a contextualized approach on such theory. 相似文献

This paper gives background information on early childhood services in Ireland and presents the results of a survey of the preschool experiences of 1065 children. The results of the survey suggest that the majority of children experienced some form of early childhood service before starting school. The most common service was a playgroup although a significant proportion of the children had experienced home‐based care with a relative or family day care provider. The implications of the findings for the development of a policy on early childhood services are discussed. 相似文献

Despite its frequent use, there is little understanding of the concept of differential among upper high school and undergraduate
students of physics. As a first step to identify the origin of this situation and to revert it, we have done a historic and
epistemological study aimed at clarifying the role and the meaning of the differential in physics and at improving curricular
and teaching models in the sense of Gilbert et al. (Gilbert J.K., Boulter C., & Rutherford, M.: 1998a, International Journal of Science Education 20(1), 83–97, Gilbert J.K., Boulter C., & Rutherford, M.: 1998b, International Journal of Science Education 20(2), 187–203). We describe the contributions of Leibniz and Cauchy and stress their shortcomings, which are overcome by the
alternative definition proposed by the French mathematician Fréchet, dating from early 20th century. As a result of this study,
we answer to some fundamental questions related to a proper understanding of the differential in physics education (for 17–19 years
old students). 相似文献

The Inductive Query By Example (IQBE) paradigm allows a system to automatically derive queries for a specific Information Retrieval System (IRS). Classic IRSs based on this paradigm [Smith, M., & Smith, M. (1997). The use of genetic programming to build Boolean queries for text retrieval through relevance feedback. Journal of Information Science, 23(6), 423–431] generate a single solution (Boolean query) in each run, that with the best fitness value, which is usually based on a weighted combination of the basic performance criteria, precision and recall. 相似文献

This article examines how 31 triads of 6- to 10-year-old children from 3 cultural backgrounds organized their interactions while folding Origami figures. Triads of children whose families had immigrated to the United States from indigenous heritage regions of México (and whose mothers averaged only 7 grades of schooling) coordinated more often as an ensemble, whereas triads of European heritage U.S. children whose mothers had extensive schooling more often engaged dyadically or individually. When the European heritage children did engage as an ensemble, this often involved chatting rather than nonverbal conversation regarding folding, which was more common among the Mexican heritage children. Mexican heritage U.S. triads whose mothers had extensive schooling showed an intermediate pattern or resembled the European heritage children. 相似文献

The aims of this study were (a) to determine whether Spanish children with reading disabilities (RD) show a speech perception deficit and (b) to explore the locus and nature of this perceptive deficit. A group of 29 children with RD, 41 chronological age-matched controls, and 27 reading ability-matched younger controls were tested on tasks of speech perception. The effect of linguistic unit (word vs. syllable) and type of phonetic contrast (voicing, place and manner of articulation) were analyzed in terms of the number of errors and the response time. The results revealed a speech perception deficit in Spanish children with RD that was independent of the type of phonetic contrast and of linguistic unit. 相似文献
