The statutory ‘phonics screening check’ was introduced in 2012 and reflects the current emphasis in England on teaching early reading through systematic synthetic phonics. The check is intended to assess children's phonic abilities and their knowledge of 85 grapheme–phoneme correspondences (GPCs) through decoding 20 real words and 20 pseudo words. Since the national rollout, little attention has been devoted to the content of the checks. The current paper, therefore, reviews the first three years of the check between 2012 and 2014 to examine how the 85 specified GPCs have been assessed and whether children are only using decoding skills to read the words. The analysis found that out of the 85 GPCs considered testable by the check, just 15 GPCs accounted for 67% of all GPC occurrences, with 27 of the 85 specified GPCs (31.8%) not appearing at all. Where a grapheme represented more than one phoneme, the most frequently occurring pronunciation was assessed in 72.2% of cases, with vocabulary knowledge being required to determine the correct pronunciation within real words where multiple pronunciations were possible. The GPCs assessed, therefore, do not reflect the full range of GPCs that it is expected will be taught within a systematic synthetic phonics approach. Furthermore, children's ability to decode real words is dependent on their vocabulary knowledge, not just their phonic skills. These results question the purpose and validity of the phonics screening check and the role of synthetic phonics for teaching early reading. 相似文献

Federal legislation has driven and been receptive to the vision of a rigorous, relevant career and technical education (CTE) system integrated with academics and aligned across middle school, secondary school, and postsecondary education. This article uses a social policy analysis approach to trace the history of federal CTE policy throughout the 20th century and the beginning of the 21st century. Through this overview, we demonstrate how federal CTE policy has repeatedly evolved and responded to changing economic and social needs, while also incorporating policy flexibility that has led to variation in program implementation on the state and local levels. 相似文献

Honours study is viewed as a transition from undergraduate to postgraduate study and/or to enhanced career prospects. In Australia, Honours is usually an adjunct to the standard undergraduate degree. This paper provides an ethnographic study of 10 Australian Honours students. Seeing their experience through their reflections, in their own voices, reveals that Honours may be more than transitional – these students were transformed personally. Such emotionally charged transformations require academics to reflect on the best forms of support for Honours students. 相似文献

As teachers enter the school communities of their initial practice, they experience identity shifts that reflect their learning. Throughout teacher education they have constructed an identity informed by their previous school experiences, the ideas and approaches promoted by their teacher education programs, and an ideal of the teachers they hope to become. The complex set of influences at the boundary between their lives as students and their lives as professionals causes them to confront their identities in new and sometimes disruptive ways (Flores & Day, 2006). New teaching situations introduce them to the thinking of experienced teachers, and to the needs of their first groups of learners, challenging the notions they have so far developed about who they are as teachers (Smagorinsky, Cook, Moore, Jackson, & Fry, 2004). This paper reports on interviews with 35 new teachers as they graduate from teacher education programs and enter the profession, and details their learning about agency and role in community resulting in identity changes within this boundary space. 相似文献

The Science Teachers Learning from Lesson Analysis (STeLLA) project is a videobased analysis‐of‐practice PD program aimed at improving teacher and student learning at the upper elementary level. The PD program developed and utilized two “lenses,” a Science Content Storyline Lens and a Student Thinking Lens, to help teachers analyze science teaching and learning and to improve teaching practices in this year‐long program. Participants included 48 teachers (n = 32 experimental, n = 16 control) and 1,490 students. The STeLLA program significantly improved teachers' science content knowledge and their ability to analyze science teaching. Notably, the STeLLA teachers further increased their classroom use of science teaching strategies associated with both lenses while their students increased their science content knowledge. Multi‐level HLM analyses linked higher average gains in student learning with teachers' science content knowledge, teachers' pedagogical content knowledge about student thinking, and teaching practices aimed at improving the coherence of the science content storyline. This paper highlights the importance of the science content storyline in the STeLLA program and discusses its potential significance in science teaching and professional development more broadly. © 2011 Wiley Periodicals, Inc., J Res Sci Teach 48: 117–148, 2011 相似文献

The present study examined the relations of Chinese word reading and writing to both maternal mediation of writing and a number of metalinguistic and cognitive skills in 63 Hong Kong Chinese kindergarteners. The whole process of maternal mediation of writing, in which mothers individually facilitated their children's writing of 12 two‐character words in their own ways, was videotaped. This study replicated and extended previous work on the cognitive strategies mothers use to help children in writing Chinese words. Mothers' typical mediation strategies were positively and significantly associated with both children's independent word reading and writing. In addition, maternal mediation of writing was uniquely associated with Chinese word reading, but not word writing, even with metalinguistic and cognitive skills, including phonological awareness, morphological awareness, orthographic processing and visual knowledge, statistically controlled. Findings underscore the importance of mothers' early scaffolding in facilitating children's literacy acquisition. 相似文献
