Jonathan Glazzard 《English in Education》2017,51(2):130-142

The purpose of this article is to question the suitability of the phonics screening check in relation to models and theories of reading development. The article questions the appropriateness of the check by drawing on theoretical frameworks which underpin typical reading development. I examine the Simple View of Reading developed by Gough and Tunmer and Ehri's model of reading development. The article argues that the assessment of children's development in reading should be underpinned and informed by a developmental framework which identifies the sequential skills in reading development.  相似文献   

基于极化分解组合的SAR图像视觉优化和建筑物损毁评估     

刘杉  张风丽  韦诗莹  刘娜  邵芸 《中国科学院大学学报》2020,37(6):750-759

建筑物损毁评估对灾害应急监测具有重要意义。极化SAR图像蕴含丰富的地物信息，并且记录有目标地物的极化散射矩阵，可用于建筑物的损毁评估。针对完好和损毁建筑物两类目标的散射特征，利用Touzi分解散射角α_s1、去定向后Yamaguchi分解二次散射分量和Touzi分解散射对称度|τ₂|进行RGB彩色合成，对极化SAR图像进行视觉优化，进而利用单一时相SAR图像快速识别出不同损毁程度的建筑物区域。以2011年3月11日发生在日本东北部海域的地震为例，利用灾后的ALOS PALSAR全极化数据开展实验分析，并利用汶川地震RADARSAT-2图像对提出的方法进行验证。结果表明，通过对极化参量的组合不仅可以优化建筑物目标的视觉显示效果，同时可提高不同损毁程度建筑物区域识别度，从而大大降低灾害评估对于数据源的限制和要求。  相似文献   

安全情报概念的由来、演进趋势及涵义——来自安全科学学理角度的思辨     

王秉  吴超 《图书情报工作》2019,63(3):45-53

[目的/意义]安全问题是当前国家、政府、企业、社会、大众及学界广泛关注的一个重要现实问题，而安全情报是保障安全的必用之宝，故安全情报研究具有十分重要的理论与现实意义。[方法/过程]运用文献分析法和思辨法，从安全科学学理角度出发，论证基于安全科学视角解读与界定安全情报概念的必要性、重要性与紧迫性，探讨安全情报概念的由来与演进趋势，并分析安全情报的涵义。[结果/结论]从安全科学学理角度看，从安全信息到安全情报的安全管理新认识是提出安全情报概念的根本动力，安全情报概念的总体演进趋势是从分散到统一。同时，从系统安全学角度看，安全情报是指所有影响系统安全行为的安全信息。  相似文献

The Potential Impact of COVID-19 on Student Learning and How Schools Can Respond     

Adam E. Wyse  Eric M. Stickney  David Butz  Amanda Beckler  Catherine N. Close 《Educational Measurement》2020,39(3):60-64

There is no denying the impact that the coronravirus disease (COVID-19) outbreak has had on many aspects of our lives. This article looks at the potential impact of COVID-19 on student learning as schools abruptly morphed into virtual learning environments using data from several instructional, practice, and assessment solutions offered by Renaissance. First, three hypothetical learning scenarios are considered using normative data from Star assessments to explore the potential impact on reading and math test performace. Next, data on Focus Skills are used to highlight which grades may have missed the most foundational math and reading content if instruction was stopped or reduced. Last, data from two of Renaissance's practice tools are used to evaluate whether students were practicing key skills following school closures. The article concludes that academic decline will likely occur but may be tempered by the increased use of practice tools; effects may look different for math and reading; and may impact grades and schools differently. As such, schools may need to leverage decision-making frameworks, such as the Multi-tiered Systems of Support/Response-to-Intervention (MTSS/RTI) framework, more than ever to identify needs and target instruction where it matters most when school begins in fall 2020.  相似文献   

Strength,Weakness, Opportunity,Threat (SWOT) Analysis of the Adaptations to Anatomical Education in the United Kingdom and Republic of Ireland in Response to the Covid-19 Pandemic     

Georga J. Longhurst  Danya M. Stone  Kate Dulohery  Deirdre Scully  Thomas Campbell  Claire F. Smith 《Anatomical sciences education》2020,13(3):301-311

The Covid-19 pandemic has driven the fastest changes to higher education across the globe, necessitated by social distancing measures preventing face-to-face teaching. This has led to an almost immediate switch to distance learning by higher education institutions. Anatomy faces some unique challenges. Intrinsically, anatomy is a three-dimensional subject that requires a sound understanding of the relationships between structures, often achieved by the study of human cadaveric material, models, and virtual resources. This study sought to identify the approaches taken in the United Kingdom and Republic of Ireland to deliver anatomical education through online means. Data were collected from 14 different universities in the United Kingdom and Republic of Ireland and compared adopting a thematic analysis approach. Once themes were generated, they were collectively brought together using a strength, weakness, opportunity, threat (SWOT) analysis. Key themes included the opportunity to develop new online resources and the chance to engage in new academic collaborations. Academics frequently mentioned the challenge that time constrains could place on the quality and effectiveness of these resources; especially as in many cases the aim of these resources was to compensate for a lack of exposure to cadaveric exposure. Comparisons of the actions taken by multiple higher education institutions reveal the ways that academics have tried to balance this demand. Discussions will facilitate decisions being made by higher education institutions regarding adapting the curriculum and assessment methods in anatomy.  相似文献

A Process for Reviewing and Evaluating Generated Test Items     

Mark J. Gierl  Hollis Lai 《Educational Measurement》2016,35(4):6-20

Testing organization needs large numbers of high‐quality items due to the proliferation of alternative test administration methods and modern test designs. But the current demand for items far exceeds the supply. Test items, as they are currently written, evoke a process that is both time‐consuming and expensive because each item is written, edited, and reviewed by a subject‐matter expert. One promising approach that may address this challenge is with automatic item generation. Automatic item generation combines cognitive and psychometric modeling practices to guide the production of items that are generated with the aid of computer technology. The purpose of this study is to describe and illustrate a process that can be used to review and evaluate the quality of the generated item by focusing on the content and logic specified within the item generation procedure. We illustrate our process using an item development example from mathematics drawn from the Common Core State Standards and from surgical education drawn from the health sciences domain.  相似文献
