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.

Spelling skills have been identified as one of the major barriers to written text production in young English writers. By contrast oral language skills and text generation have been found to be less influential in the texts produced by beginning writers. To date, our understanding of the role of spelling skills in transparent orthographies is limited. The current study addressed this gap by examining the contribution of spelling, oral language and text generation skills in written text production in Italian beginner writers. Eighty-three children aged 7–8 years participated in the study. Spelling, lexical retrieval, receptive grammar, and written sentence generation and reformulation skills were assessed and children were asked to write a text on a set topic. A factor analysis revealed that the children’s written text production was captured by three factors: productivity, complexity and accuracy. In contrast to results from children learning to write in opaque orthographies, such as English, this study showed that receptive grammar and written sentence generation skills accounted for significant variance in measures of productivity, complexity and accuracy in Italian children’s written text production. Spelling skills contributed to text accuracy and quality and explained more variance than receptive grammar in microstructural accuracy. By contrast, oral grammatical skills explained more variance in text quality than spelling. The current study shows the differential impact of language systems, such as Italian, on written text production. Implications for assessment and instruction are outlined.  相似文献

ABSTRACT

The paper presents a theorisation of pedagogic knowledge formation, as a continuous attempt to understand the positions in discourse we occupy. The paper documents some participatory practitioner research by teacher educators centred on a course development initiative for student teachers of English, at an English university. Students researched their experiences of becoming a teacher within a course that was largely school-based, whilst their tutors researched their own involvement in the process (the main focus of this paper). Drawing on Lacanian theory, tutors are depicted as learning subjects having more or less certainty or doubt about the knowledge they possess. In attempting to understand this interplay of certainty and doubt, tutors arrive at stronger conceptualisations of learning. Through this approach, the paper provides a theoretically informed conception of professional knowledge, as involving a process of renewing ideas about learning, in meeting or resisting external demands.  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.

Research indicates that affective attitudes such as liking of a subject and confidence in one’s ability within a subject predict academic performance. Generally, immigrant minority students have positive attitudes and often have low academic performance. This study examines the self-efficacy and liking of subjects of New Zealand students and analyses the relationship of those attitudes towards academic performance in mathematics, writing, and reading by self-reported ethnicity. Data were obtained from the norming samples from the Assessment Tools for Teaching and Learning project in New Zealand. Of special interest are the relationships between attitude and performance for Pasifika and Tongan students in New Zealand. Tongan and Pasifika students had positive attitudes, but their mean scores were not significantly different to other ethnic groups except in writing for Tongan students. Tongan and Pasifika students did have lower academic performance than majority and Asian immigrant students in all three subjects. The correlation between liking and self-efficacy was fundamentally zero for Tongan and Pasifika students, while it was weakly positive for majority and Asian immigrant students. Together these results question the power of self-efficacy and liking attitudes to predict academic performance for immigrant students from agrarian or traditional societies. Further, the data suggest that ‘school effects’ are most likely explanations for this relationship, rather than lack of attachment, opposition, or deficiency theories.  相似文献

Catholic schools have become a popular choice for many low income families Latino/a families. Families enrollment in these schools are often faced with the mandate to participate. However, regardless of the mandate, some schools often experience low parental participation. The purpose of this study is to document the experiences of low income, Latino/a families around parental involvement in hopes of understanding the reasoning for participating (or not) in their child’s school. The researchers conclude that families do not participate for a number of reasons including lack of opportunities, and an unwelcoming environment. The implications for Latina/o urban education are discussed.  相似文献
