Meta-analysis refers to the statistical methods used in research synthesis for combining and integrating results from individual studies. In this regard meta-analytical studies share with narrative reviews the goal of synthesizing the scientific literature on a particular topic, while as in the case of standard articles they present new results. This study aims to identify the potential similarities and differences between meta-analytical studies, reviews and standard articles as regards their impact and structural features in the field of psychology. To this end a random sample of 335 examples of each type of document were selected from the Thomson Reuters Web of Science database. The results showed that meta-analytical studies receive more citations than do both reviews and standard articles. All three types of documents showed a similar pattern in terms of institutional collaboration, while reviews and meta-analytical studies had a similar number of authors per document. However, reviews had a greater number of references and pages than did meta-analytical studies. The implications of these results for the scientific community are discussed. 相似文献

Checking the identity of students and authorship of their online submissions is a major concern in Higher Education due to the increasing amount of plagiarism and cheating using the Internet. The literature on the effects of e-authentication systems for teaching staff is very limited because it is a novel procedure for them. A considerable gap is to understand teaching staff' views regarding the use of e-authentication instruments and how they impact trust in e-assessment. This mixed-method study examines the concerns and practices of 108 teaching staff who used the TeSLA—Adaptive Trust-based e-Assessment System in six countries: the UK, Spain, the Netherlands, Bulgaria, Finland and Turkey. The findings revealed some technological, organisational and pedagogical issues related to accessibility, security, privacy and e-assessment design and feedback. Recommendations are to provide a FAQ and an audit report with results, to raise awareness about data security and privacy, to develop policies and guidelines about fraud detection and prevention, e-assessment best practices and course team support. 相似文献

This study explores the ways in which school-imposed labeling in a “no-excuses” charter school that was explicitly designed for the purpose of benefiting Black students, impacts teachers’ perceptions of Black male students who were labeled as being high risk or struggling academically, and how these students perceive their own schooling experiences. A conceptual framework with the history of how and why Black masculinity is constructed as deviant and different in the context of U.S. schools, as well as the impact of labeling on Black male students’ learning and self-esteem are detailed. While centering the labeled-students’ experiences, we examine the interactions between key stakeholders (i.e., labeled-students, teachers/administrators, and non-labeled students) at the charter school and overall the findings speak clearly to how language of deficit and pathology impacted Black male students’ schooling experiences as they negotiate racial stigma as racialized bodies at a “no-excuses” public charter school. 相似文献

ABSTRACTIn the last four years, we have been researching how five groups of young people were learning inside and outside secondary schools. The novelty of this proposal was to invite these young people to act as researchers by carrying out their own ethnographic cases. As a result we produced 10 ethnographic reports – 5 prepared by students and 5 by the university research team. In this paper, we show part of the conversation between the five ethnographic reports written by us giving account of the processes and results of the studies implemented by students. This meta-ethnographic process tries to accomplish two main objectives: (a) to characterise the variety of youth’ learning experiences in their mobilities and transitions in and outside schools and the ways of giving account of them in the ethnographic reports; (b) reporting own learning about the possibilities and limitations of the meta-ethnographic analysis. 相似文献

The purpose of the present study was to test the factor structure of the McCarthy Scales of Children's Abilities in preschool children. Seventy-two boys and 69 girls between 4 and 5 years of age were tested. A factor analysis was carried out by means of the principal components method with varimax rotation. The existence of the Verbal factor and of the Perceptual-Performance factor was confirmed. The Quantitative and Memory factors appear undifferentiated. As far as the subtests which make up the Motor scale are concerned, they do not constitute a single factor. The significance of these findings is discussed. 相似文献

This study examined the effect of sample size ratio and model misfit on the Type I error rates and power of the Difficulty Parameter Differences procedure using Winsteps. A unidimensional 30-item test with responses from 130,000 examinees was simulated and four independent variables were manipulated: sample size ratio (20/100/250/500/1000); model fit/misfit (1 PL and 3PLc =. 15 models); impact (no difference/mean differences/variance differences/mean and variance differences); and percentage of items with uniform and nonuniform DIF (0%/10%/20%). In general, the results indicate the importance of ensuring model fit to achieve greater control of Type I error and adequate statistical power. The manipulated variables produced inflated Type I error rates, which were well controlled when a measure of DIF magnitude was applied. Sample size ratio also had an effect on the power of the procedure. The paper discusses the practical implications of these results. 相似文献

It is argued that the lack of consensus on what constitutes an inquiry-based approach makes the generalization about it difficult, because the concept is relatively unspecific and vague. This problem can partially be solved by constructing a set of activities promoted by inquiry, thus defining the inquiry objectives for classroom and laboratory teaching. Five high school and college Mexican teachers＇ PICK （pedagogical inquiry/content knowledge） was documented and assessed by means of Loughran, Mulhall and Berry＇s （2004） l-CoRe （inquiry content representation） developed by the authors through a proposal of a set of seven inquiry activities. They were also interviewed to construct the professional and pedagogical experience repertoires, a second tool by Loughran et al. （2004） to document PICK. It was observed that all teachers interviewed have used inquiry to modify their students＇ way of thinking, mainly through question posing. Some of them employed research as their main tool to promote scientific inquiry but others mentioned the lack of time to do it. It is interesting to notice that in spite of the fact that inquiry is out of the curriculum in M6xico, the teachers make use of it to improve their teaching practice. According to their answers, their actions in the classroom or the lab were classified within the three general approaches expressed by Lederman （2004）： implicit, historical and explicit. It is concluded that a given teacher cannot be classified exclusively in one of them, because in his/her activities one general approach overlaps the others. The authors conclude that Lederman＇s classification has to be taken into account as an orientation to characterize a given activity of one teacher, even though the same teacher may use another activity characterized by other general approach. That is, Lederman＇s classification applies to characterize activities, not persons 相似文献

This paper presents an international comparison of Australian and Spanish secondary teachers’ perceptions about the effectiveness of their pre-service education and their learning as in-service teachers. It aims to identify, firstly, the extent to which beginning teachers believe they are prepared for their careers through their teacher training and, secondly, what teachers have learned as practicing teachers. A qualitative case study was conducted to uncover whether similar issues raised by early career teachers were identified in different contexts. Data were collected through interviews with secondary teachers (N = 11) from Australia and Spain in their third year of full-time teaching. Findings suggest similar positive perceptions towards their practicum experiences, transition to beginning teachers and professional development. However, differences were found in their early career experiences regarding professional learning and their development of identity. Implications of the study are discussed by identifying strategies to improve pre-service education for secondary teachers. 相似文献
