Student performance data from a post-92 university in the United Kingdom showed that, for a substantial minority of programmes, there was a general dip in marks between Years 1 and 2. Longitudinal and cross-sectional data were analysed in order to ascertain whether the latter (with its advantage of a more rapid production of results) would make an adequate proxy for the former: the analyses suggest that it can do. The article discusses a number of factors that have to be borne in mind, particularly if cross-sectional analyses are undertaken. 相似文献

INTRODUCTION The problem of creating a virtual human has received a lot of attention in the last few decades, due to the increasing popularity of applications involving human figures, such as movies and computer games. There are many approaches to create a virtual human body. Traditional ways for creating a virtual human figure include employing 3D body scanners or using 3D modeling techniques based on understanding of human anatomy. Detailed 3D human body model can be acquired easily us… 相似文献

In the phase of field evaluation, the changing of interwell reservoir may be out of control if the geological model was built only on well data due to few existing wells. The uncertainty of the interwell reservoir interpolation based only on well data can be decreased by comprehensive utilization of geological, logging and seismic data, especially by using highly relative seismic properties from 3D seismic data adjusted by well point data to restrict interpolation of geological properties. A 3D-geological model which takes the sand body as the direct modeling object was built through stacking the structure, reservoir and water/oil/gas properties together in 3D space. 相似文献

In this article, we examine teachers’ use of knowledge sources in meetings where they discuss and formulate initiatives and solutions to develop existing teaching practice based on national test results. While practices of data use have been extensively researched, less attention has been given to the content of data use practices. Analyses of what kind of knowledge sources are used, and how, in discussions about student performance levels and accompanying initiatives to improve teaching can yield important insight into the potential and pitfalls of local data use practices. Based on an analysis of the knowledge sources that Norwegian secondary school teachers draw upon in so-called ‘result meetings’ and of the prognostic frames that teachers initiate, we find that teachers use several knowledge sources and that their data use practices can be characterised as complex and ‘thick’, although the data itself are ‘thin’. However, although teachers draw upon a range of knowledge sources and integrate these when identifying possible solutions, the solutions themselves are often short-term and directed towards improving test results. In order for teachers to ask more fundamental questions regarding existing practices, more attention should be directed towards problem-solving processes and also whether result meetings can provide arenas for complex problem-solving. 相似文献

Abstract Much laboratory work in school science involves observation and measurement; an important development, in recent years, has been the application of computers to this activity. Data-logging techniques have been available to science teachers for some time (outside the United Kingdom [UK], this technology is sometimes known as microcomputer-based laboratories or MBL). It is only relatively recently, however, that data-logging technology has become sufficiently user-friendly and affordable for it to be more widely adopted. The use of sensors, interfaces and data-loggers to capture and record data, and its subsequent display and analysis using computer software, now constitute a realistic alternative to traditional approaches. With the National Curriculum for initial teacher training including information and communications technology now in place in the UK, the time seems opportune to take stock of current use of data-logging methods and to consider how they might be further developed. This article describes how data-logging currently appears to be used in science lessons. It considers how the demands of the National Curriculum have shaped current practice, and argues for a shift of emphasis in the pupils' role in data-logging activities. Some suggestions are then offered for encouraging pupils to engage in more interpretative activity, which recent software readily supports. 相似文献

Background knowledge is important for data mining, especially in complicated situation. Ontological engineering is the successor of knowledge engineering. The sharable knowledge bases built on ontology can be used to provide background knowledge to direct the process of data mining. This paper gives a common introduction to the method and presents a practical analysis example using SVM (support vector machine) as the classifier. Gene Ontology and the accompanying annotations compose a big knowledge base, on which many researches have been carried out. Microarray dataset is the output of DNA chip. With the help of Gene Ontology we present a more elaborate analysis on microarray data than former researchers. The method can also be used in other fields with similar scenario. 相似文献

This paper examines the effect of attending elite private high school on college placement using admissions data from the most selective high school in a large metropolitan area. To overcome omitted variable bias, we limit the sample to admitted applicants and control directly for the scores assigned by admissions based on in-depth analyses of the applicants and their families. In addition, we control for a wide set of covariates including student and family characteristics and entrance exam scores. Results indicate that attending selective private high school rather than other public and private high schools causes students to attend more selective universities. Effects are driven by gains for girls and students from lower-income neighborhoods. 相似文献

INTRODUCTION The first phases of the product life cycle are almost completely digitalized nowadays. Single parts or complete product models are modeled with 3D CAD solutions. Assembling single parts to digital mockups (DMUs) is important for checking the de- pendencies between the parts and detecting conflicts. Due to their complexity, such data is managed in specialized Product Data Management (PDM) sys- tems. They gained an increasing importance in many industries during the last d… 相似文献

The impact of collaboration on teachers’ individual data use 总被引：1，自引：1，他引：0

Research considers collaboration to be a significant factor in terms of how teachers use data to improve their practice. Nevertheless, the effects of teacher collaboration with regard to teachers’ individual data use has remained largely underexplored. Moreover, little attention has been paid to the interplay between collaboration and the personal factors that influence teachers’ data use. This paper addresses this research gap by defining factors that affect collaboration, and by investigating the impact of collaboration on teachers’ individual data use. The resulting research questions were answered by drawing on questionnaire data from 1,472 primary and secondary school teachers in Flanders. The findings indicate that collaboration is the main explanatory factor for teachers’ individual data use compared to teachers’ self-efficacy and attitude. Therefore, this study demonstrates the value of collaboration for future research and for creating a supportive environment for teachers’ individual data use. 相似文献

Poor-quality, or completely absent, data deny millions of children the right to an education. This is often the case in conflict-ridden areas. The 2011 Education for All Global Monitoring Report (UNESCO 2011b) identified four failures that are holding back progress in education and damaging millions of children’s lives: failures of protection, provision, reconstruction, and peace-building. Thus, the critical lack, and the varying quality, of data on education and on human rights violations against children during and after armed conflicts amount to what can be termed the fifth failure of the international community. This article examines how currently available data, and monitoring and evaluation systems, can be used and improved to better estimate the situation of children in conflict-affected countries, in particular with respect to education. In the light of international standards for data dissemination and data quality, it highlights the need for governments and the international community to expand our current capacity to provide general information on the impact that conflict has on education, children, parents, and schools, to ensure the right to education for millions of children living in conflict-affected countries. Such an effort would include specific steps to ensure higher data quality in terms of completeness and accuracy, timeliness, serviceability, and methodological soundness. 相似文献

The editors of a recent special edition of Qualitative Studies in Education map a new field of post-qualitative research and raise fundamental questions about core concepts such as ‘method’ and ‘data.’ They ask whether qualitative inquiry as we know it is any longer possible if we understand language, the human and the material as completely imbricated. In taking up the relation between language and representation as core to what is proposed as the ‘new new,’ the paper examines these questions in relation to data generated in a project called ‘Love Your Lagoons’ conducted with 10 schools and 300 children in Sydney’s water catchment. In particular, the paper focuses on data from one secondary school that offered ‘Regeneration’ as a sport option in which the students walked to their local Redbank Creek every week and spent time there. By closely attending to the circumstances of the collection of data and analyzing it through approaches offered within the ‘new new,’ insights into the relationship between language, materiality, and the human are offered. Summary comments are made about the politico/ethical project of the post-human I and the relevance of data and method to such post-qualitative inquiry. 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

Schools’ socioeconomic status (SES) has been claimed as an important influence on student performance and there are calls for a policy response. However, there is an extensive literature which for various reasons casts doubt on the veracity of school-SES effects. This paper investigates school-SES effects with population data from a longitudinal cohort of school students which includes achievement measures in Years 3, 5 and 7. Estimates for school-SES are unstable under differing model and measurement specifications. School-SES effects are trivial controlling for student- and school-level prior ability. Inconsistent with theoretical explanations, school-SES effects were stronger with weaker SES measures. Furthermore, school-SES effects differ somewhat by achievement domain. Also contrary to expectations, there were school-SES effects on Year 7 achievement in secondary school for the primary schools students attended in Year 5. In each of five domains of achievement, fixed effect models show a small negative effect for school-SES and a small positive effect for school-level prior ability. The large school-SES effects prominent in some research and policy literatures are statistical artefacts. 相似文献
