The lament that ‘students can’t write’ remains loud and defiant, even after years of research pointing to the myriad factors that make students’ writing challenging, particularly when they move into university. This paper reports on a longitudinal, ethnographic study which explored students’ writing ‘in transition’, from A-levels to university in the UK, through the critical lens offered by the academic literacies conceptual framing. This paper offers critical analysis of the ways that students, teachers and institutions position writing at A-level and university, exploring the assumptions and beliefs that underpin their understandings and practices using Ivani?’s framework of discourses of writing. The analysis proposes that the centrality of assessment in the treatment of language at both levels creates an ‘assessment discourse of writing’, which originates in school, and becomes a defining and restrictive frame for students’ writing as they move into higher education. The analysis further suggests that assessment is the principal cause for the students’ challenges with adapting to the writing requirements of university. Moreover, assessment is used as a metalanguage for discussing writing at A-levels, and can become an unhelpful ‘anchor of continuance’ for students as they move into university. 相似文献

It has been shown (Lawrence, S. (2001). Online or invisible? Nature, 411, 521) that journal articles which have been posted without charge on the internet are more heavily cited than those which have not been. Using data from the NASA Astrophysics Data System (ads.harvard.edu) and from the ArXiv e-print archive at Cornell University (arXiv.org) we examine the causes of this effect. 相似文献

This study examined parent-child emotion discourse, children's independent social information processing, and social skills outcomes in 146 families of 8-year-olds with and without developmental delays. Children's emergent social-cognitive understanding (internal state understanding, perspective taking, and causal reasoning and problem solving) was coded in the context of parent-child conversations about emotion, and children were interviewed separately to assess social problem solving. Mothers, fathers, and teachers reported on children's social skills. The proposed strengths-based model partially accounted for social skills differences between typically developing children and children with delays. A multigroup analysis of the model linking emotion discourse to social skills through children's prosocial problem solving suggested that processes operated similarly for the two groups. Implications for ecologically focused prevention and intervention are discussed. 相似文献

The authors propose the Interactive Training Model (ITM), a full classroom role play experience, as a method for helping student counselors develop essential interviewing and counseling skills and self‐awareness as required by the 2009 Council for Accreditation of Counseling and Related Educational Programs Standards. This pre‐post, quasiexperimental study involving 45 master's‐level students indicated that those who participated in the ITM made greater gains in supervisee development compared with those who participated in a traditional peer feedback model. Narrative student feedback regarding the use of ITM in an essential skills course is presented, and implications for counselor education are discussed. 相似文献

Many motile bacteria are propelled by the rotation of flagellar filaments. This rotation is driven by a membrane protein known as the stator-complex, which drives the rotor of the bacterial flagellar motor. Torque generation is powered in most cases by proton transit through membrane protein complexes known as stators, with the next most common ionic power source being sodium. Sodium-powered stators can be studied through the use of synthetic chimeric stators that combine parts of sodium- and proton-powered stator proteins. The most well studied example is the use of the sodium-powered PomA-PotB chimeric stator unit in the naturally proton-powered Escherichia coli. Here we designed a fluidics system at low cost for rapid prototyping to separate motile and non-motile populations of bacteria while varying the ionic composition of the media and thus the sodium-motive force available to drive this chimeric flagellar motor. We measured separation efficiencies at varying ionic concentrations and confirmed using fluorescence that our device delivered eightfold enrichment of the motile proportion of a mixed population. Furthermore, our results showed that we could select bacteria from reservoirs where sodium was not initially present. Overall, this technique can be used to implement the selection of highly motile fractions from mixed liquid cultures, with applications in directed evolution to investigate the adaptation of motility in bacterial ecosystems. 相似文献

AbstractConsiderable research evidence supports the provision of explicit instruction for students at risk for reading difficulties; however, one of the most widely implemented approaches to early reading instruction is Guided Reading (GR; Fountas & Pinnel, 1996), which deemphasizes explicit instruction and practice of reading skills in favor of extended time reading text. This study evaluated the two approaches in the context of supplemental intervention for at-risk readers at the end of Grade 1. Students (n = 218) were randomly assigned to receive GR intervention, explicit intervention (EX), or typical school instruction (TSI). Both intervention groups performed significantly better than TSI on untimed word identification. Significant effects favored EX over TSI on phonemic decoding and one measure of comprehension. Outcomes for the intervention groups did not differ significantly from each other; however, an analysis of the added value of providing each intervention relative to expected growth with typical instruction indicated that EX is more likely to substantially accelerate student progress in phonemic decoding, text reading fluency, and reading comprehension than GR. Implications for selection of Tier 2 interventions within a response-to-intervention format are discussed. 相似文献
