Despite the high stakes attached to students’ performance on assessments of academic writing, we still know little about the challenges students face when composing in academic contexts. To begin to address this problem, two studies were designed with the following aims: to identify and describe the most prevalent types of academic writing at the secondary level, and to characterize the challenges that both English Language Learners (ELLs) and non-English-Language Learners (non-ELLs) experience with this type of writing. Findings from these studies reveal that (1) in the context of New York City schools, exposition/argument is the most prevalent genre assigned as a writing task in secondary classrooms, as well as the most valued; and that (2) while both Intermediate ELLs and non-ELLs articulated Translating (the process of articulating ideas in the conventions of written English) as the most frequent challenge, the two groups differed in the kinds of Translating challenges and in the types and range of other challenges they articulated: ELLs articulated fewer challenges specifically related to the genre of exposition than did non-ELLs. Based on these findings we suggest several new approaches to classroom diagnostic assessment of writing, and raise issues to be considered in these approaches.  相似文献

Writing task variants can increase test security in high-stakes essay assessments by substantially increasing the pool of available writing stimuli and by making the specific writing task less predictable. A given prompt (parent) may be used as the basis for one or more different variants. Six variant types based on argument essay prompts from a large-scale, high-stakes North American writing assessment and six based on issue prompts from the same test were created and evaluated in the research section of the test administrations in the winter of 2009. Examinees were asked to volunteer to write an essay on one of the new prompt/variant tasks. Essays were obtained from 7573 examinees for argument prompts and 10,827 examinees for issue prompts. Results indicated that all variant types produced reasonably similar means, standard deviations, and rater reliabilities, suggesting that the variant strategy should be useable for operational administrations in high stakes essay assessments. Variant type did not interact with gender, ethnicity, or language (self-report that English or another language is the examinee's “best” language).  相似文献

This paper reports on a quasi-experimental study comparing the effects of peer-editing to self-editing on improving students’ revised drafts. The study involved two intact classes (experimental and control groups) of an English course. The experimental group practiced peer-editing while the control group engaged in self-editing. After receiving sufficient training in their respective type of editing, both groups wrote a graded argumentative essay in two drafts. Results of a MANCOVA test carried out on the graded essay written by the two groups showed a statistically significant difference in revised writing in favour of peer-editing. A random sample of seven peer-edited and self-edited essays was analyzed to determine the differences between peer-editors’ and self-editors’ ability to notice errors, revise, and improve them. Results revealed that while peer-editors and self-editors had more or less the same noticing ability, writers who engaged in self-editing revised more errors than writers who received peer-feedback. In contrast, writers who engaged in peer-editing improved their revised drafts more than self-editors did. Differences in revised writing performance between the two groups are attributed to the use of language learning strategies, peer interaction, and engagement with language. The paper concludes with implications for classroom teaching/learning and recommendations for future research.  相似文献

Significant challenges confront many Westernised institutions of higher education. Financial pressures, the increasing commodification of higher education and the insistent demands of the global marketplace, have changed the configuration of academe. One of the immediate consequences has been that the role of the professoriate has altered through unrelenting pressure to serve the managerial interests of the university rather than the scholarly interests of the field. The new competitive realities of the corporatised university have inevitably and irrevocably changed the role of the contemporary professoriate. What is now required is a defence of the university as a public institution and the advancement of public intellectual inquiry. This is the fundamental challenge for the professoriate in the twenty-first-century university.  相似文献

Given international use of video-based reflective discussions in teacher education, and the limited knowledge about whether teachers apply learning from these discussions, we explored teachers’ learning of new ideas about pedagogy and their self-reported application of this learning. Nine inservice and 48 preservice teachers participated in video-based reflective discussions and documented their learning, sources of knowledge that contributed to their learning, and application of this learning to their teaching in their practica courses. A total of 227 response sheets with this information were collected. Multilevel logit regression was used to examine how sources of learning and content learned were related to teachers’ application of learning to their teaching practices. We found that teachers reported applying 40% of their learning; particularly, what they learned about methods and materials for instruction, and that they learned from both video and discussion almost equally.  相似文献

This article undertakes a critical comparison of contemporary personalization practices on Web platforms such as YouTube and Facebook with long-established practices of narrowcasting. Though such platforms appear to adhere to goals of universality similarly adhered to by public service broadcasting (PSB), the implementation of personalization on these platforms proves problematic to their discursive positioning as free “public” services. Furthermore, though public service broadcasters have embraced personalization in the name of pluralism, critics suggest that the narrowcasting inherent in personalization exists in tension to PSB's enduring commitments. Finally, the article argues that system-initiated personalization negates the “consumer sovereignty” that narrowcasting has traditionally mobilized.  相似文献

In this first editorial paper we scope the terrain on which the JEAH is located and consider the knowledge production process that will shape the journal and, in turn, enable the journal to shape what is known and what is worth knowing. We begin by making a case for productive pluralism where we assert that the JEAH is not directly connected to a particular society or epistemic group, and so the opportunity exists for a range of work that focuses on historical understandings of educational administration to be published. We make the argument that educational administration is a field of study and practice, and that it can draw on historical perspectives and research designs to enable new insights and theoretical explanations to be developed.  相似文献

Jens Olsen (1840–1911), head principal of the Danish town of Varde was in many ways typical for his time. He was an engaging teacher and school reformer. But he was also a Christian, a believer in the ideas of the Danish priest, N. F. S. Grundtvig. Last but not least, he was curious. His curiosity and interest in the nature of children brought him in contact with the Anglo-American movement of child study. This chapter tells the story of how child studies became his way of trying to bridge the gap between the Darwinian approach to the history of humanity and a Christian view.  相似文献
