This case study of a science lesson, on the topic thermal expansion, examines the language demands on students from an integrated science and language perspective. The data were generated during a sequence of 9 lessons on the topic of ‘States of Matter’ in a Grade 7 classroom (12–13 years old students). We identify the language demands by comparing students' writings with the scientific account of expansion that the teacher intended the students to learn. The comparison involved both content analysis and lexicogrammatical (LG) analysis. The framework of Systemic Functional Linguistics was adopted for the LG analysis. Our analysis reveals differences in the meaning and the way LG resources were employed between the students' writings and the scientific account. From these differences, we found the notion of condition-of-use for LG resources to be a significant aspect of the language that students need to appropriate in order to employ the language of school science appropriately. This notion potentially provides a means by which teachers could concurrently address the conceptual and representational demands of science learning. Finally, we reflect on how the complementary use of content analysis and LG analysis provides a way for integrating the science and language perspectives in order to understand the demands of learning science through language. 相似文献

This article reveals the multiple ways in which data are constituted as a vehicle for governing teachers’ work and learning. Drawing on the concept of governance, including in relation to the sociology of numbers, and data from one school in Queensland, Australia, the research reveals how teachers’ work and learning were constituted through practices of: establishing specific ‘targets’, including various ‘audacious goals’ for school and national testing; focusing upon ‘aligning’ all forms of school, regional and national data collected within the school; and participating in various ‘data conversations’ about specific students with senior members of staff. While the research reveals how teachers found such practices beneficial for improving their practice with students, it also shows how this learning was always and everywhere framed within a broader discourse of data, and how this data-centric focus came to constitute what was valued about their work and learning, and that of their students. 相似文献

Previous research has shown that children aged 4–5 years, but not 2–3 years, show adult‐like interference from a partner when performing a joint task (Milward, Kita, & Apperly, 2014). This raises questions about the cognitive skills involved in the development of such “corepresentation (CR)” of a partner (Sebanz, Knoblich, & Prinz, 2003). Here, individual differences data from one hundred and thirteen 4‐ to 5‐year‐olds showed theory of mind (ToM) and inhibitory control (IC) as predictors of ability to avoid CR interference, suggesting that children with better ToM abilities are more likely to succeed in decoupling self and other representations in a joint task, while better IC is likely to help children avoid interference from a partner's response when selecting their own response on the task. 相似文献

This study addresses the epidemiology of knee injuries in adolescent males. Data were collected prospectively from 41 Premiership soccer academies over a 5 year period from July 2000 to June 2005. A total of 12,306 player seasons were registered in the U9 to the U16 age categories with a total of 1750 recordable injuries specific to the knee joint. There was a mean incidence of 0.71 (95% confidence interval ± 0.05) knee injuries per player per year, and a median of 17 (inter-quartile range 9-38) training days and 2 (inter-quartile range 1-4) matches missed per knee injury. Knee injuries were found to be most common in the 14-16 year age group. Six hundred and nine (35% of total) injuries were classed as severe resulting in more than 28 days' absence. Injuries were more likely to be sustained in a competitive or match-play environment (862 or 52%) than in training (796 or 48%), and a non-contact mechanism was implicated in 823 (55%) of recorded cases. Peaks in injury numbers were seen in early season and subsequent to the winter break. Sprain was the most common diagnosis recorded, with the medial collateral ligament affected in 23% of all knee injuries. Knee injuries are common in elite youth footballers. In this uninsured age group, it could be argued that earlier medical intervention may reduce long-term damage to the immature skeleton. 相似文献

This paper provides insights into teacher and school-based administrators’ responses to policy demands for improved outcomes on high-stakes, standardised literacy and numeracy tests in Australia. Specifically, the research reveals the effects of the National Assessment Program – Literacy and Numeracy (NAPLAN), and associated policies, in the state of Queensland. Drawing suggestively across Michel Foucault’s notions of disciplinary power and subjectivity, and Pierre Bourdieu’s concept of social fields, the research utilises interviews with teachers and school-based administrators to reveal how high-stakes, standardised testing practices served to discursively constitute performative teacher subjectivities around issues of funding, teacher and school reputation and target-setting within what is described as the ‘field of schooling practices’. The paper argues that the contestation evident within this field is also reflective and constitutive of more educative schooling discourses and practices, even as performative logics dominate. 相似文献

The introduction of the paperback book in the United States in 1939, and the subsequent “paperbacking of America” after 1945, permanently altered the book publishing industry in this nation. What business, societal, or governmental forces influenced the censoring of paperback books in the United States? In this article, Ian Ballantine, a leader in the paperback mass market industry, provides a personal perspective on censorship; His candid observations about individuals, books, and movements shed new light on a pivotal period in the history of the book in this country. 相似文献

This paper describes how an undergraduate department in the School of Education at the University of Wisconsin-Milwaukee grants college credits for previous learning experiences to attract and retain nontraditional students from an urban environment. At first students earned these credits by writing a loose biography, but the process by which these credits are earned has become more structured. These Prior Professional Educational Experience credits (as they are named) are now granted on a course-specific basis, where students respond in writing to questions designed to test their knowledge of competency areas offered by the department. Earning these credits has helped older students get through the university and has given them a sense of accomplishment about learnings acquired in nonuniversity settings. 相似文献
