Using student ratings to assess instructional quality of schools should fulfill three requirements: (1) an appropriate level of inter-rater agreement within schools, (2) systematic variance of student ratings between schools, (3) an adequate reliability level of aggregated student ratings. Using international PISA-data (2000–2012; 81 countries, over 55,300 schools, over 1.3 million 15-year olds) this study investigated how these requirements were met regarding indicators of instructional quality (classroom management, cognitive activation, individual learning support). We computed the interrater agreement index rWG(J), as well as the intraclass correlations ICC(1) and ICC(2). Our results showed that (1) student ratings demonstrated a moderate or strong level of agreement for most indicators of instructional quality and (2) instructional quality assessed by students varied systematically between schools. Yet, (3) reliability of aggregated student ratings was not sufficient in many countries. We discuss these results regarding conventions to evaluate agreement, variability, and reliability of student ratings at the school level. 相似文献

Previous research has confirmed peers and parents as significant agents of socialisation with respect to young people’s sexuality. The aim of this cross-sectional cohort study was to examine how parental and peer variables predict young women’s sexual behaviour and sexuality-related thoughts and emotions, and whether perceived peer influences mediate the relationship between parental variables and young person sexuality. A total of 560 female high school students of 1st (mean age 15.56 years) and 3rd grade (mean age 17.55 years), selected by means of two-stage stratified probability sampling participated in the research. Results confirmed that peer variables explained considerably more variance in participant sexuality than parental variables. Indirect parental communication about sexuality was a significant positive predictor of sexual behaviour and sexuality-related thoughts and emotions in both subsamples. The strength of direct and indirect influences of parents and peers on young people’s sexuality is determined by the age of the young person and specific aspects of adolescent sexuality. Perceived percentage of sexually active peers was the only mediator in older participants, while in the younger subsample, additional peer variables mediated the association between some parental and sexuality variables. In the discussion, special attention is given to implications of these results for planning future forms of comprehensive sexual education. 相似文献

The goal of the study presented in this article is to investigate to what extent the classification of a web page by a single genre matches the users’ perspective. The extent of agreement on a single genre label for a web page can help understand whether there is a need for a different classification scheme that overrides the single-genre labelling. My hypothesis is that a single genre label does not account for the users’ perspective. In order to test this hypothesis, I submitted a restricted number of web pages (25 web pages) to a large number of web users (135 subjects) asking them to assign only a single genre label to each of the web pages. Users could choose from a list of 21 genre labels, or select one of the two ‘escape’ options, i.e. ‘Add a label’ and ‘I don’t know’. The rationale was to observe the level of agreement on a single genre label per web page, and draw some conclusions about the appropriateness of limiting the assignment to only a single label when doing genre classification of web pages. Results show that users largely disagree on the label to be assigned to a web page. 相似文献

Combining entrepreneurial and scientific performance in academia: towards a compounded and reciprocal Matthew-effect? 总被引:2,自引:0,他引:2
The increase of entrepreneurial activity within academia has raised concerns that the research orientation of universities might become ‘contaminated’ by the application-oriented needs of industry. Empirical evidence on this concern is scarce and ambiguous. We examine whether entrepreneurial and scientific performance in academia can be reconciled. Our empirical findings (KU Leuven, Belgium) suggest that both activities do not hamper each other; engagement in entrepreneurial activities coincides with increased publication outputs, without affecting the nature of the publications involved. As resources increase, this interaction becomes more significant, pointing towards a Matthew-effect. We finally suggest that balancing both activities further depends on the institutional policies deployed. 相似文献

如果有人能够以网球为线索做一本旅行手册的话,巴黎一定会占据浓墨重彩的部分。罗兰·加洛斯是一个极具法兰西风情的名字,英雄主义色彩包裹着怀旧的腔调,但她并不是巴黎为球迷们提供的唯一礼遇。既然我们已经来到了巴黎,就没有理由错过这里的景致,你可以从横纵的街道找出她与法网的关联,也能从咖啡馆里飘窗的馥郁醇香,品出红土之外的迷人气息。 相似文献

The purpose of the paper is to examine the impact of internationalization on innovation. Specifically we explored the impact of internationalization on firms' choice for research and development (R&D) approach and technology source, impact of choice for research and development (R&D) approach and technology source on innovation and finally impact of business hampering factors on innovation. We had focused on innovation intensity to measure impact on innovation. A survey of foreign investment enterprises in Croatia was conducted. A total of 145 firms responded to the questionnaire. Multivariate analyses are used to analyze the data. In addition we identified key factors impacting different types of innovation. 相似文献

ABSTRACTThis study examines academic outcomes for university students engaged in a supplemental peer learning program in a selective institution. Using a matched sample of 1266 students, half enrolled in the supplemental program and half not enrolled, we find that participating students on average earned higher grades in linked courses. Using a subsample of students in a chemistry course sequence, we find program participants were more likely to remain in the sequence than non-participants, and that the impact was greater for students with lower levels of preparation. 相似文献

对20世纪30年代新文学史的编纂和对新文学作品的选编,需要与当时的社会和文化境况,特别是与当时的文化争论紧密联系起来.重读这些资料,有助于我们今天对当时文化界境况的了解,而且也可以重温当时对新文学的评价,从中可见五四运动的一些主要人物再三重申并肯定五四理想,同时也表现出他们的一些不自信和担心.他们反思到:他们生命中的一段历程结束了,与之诞生的文学也行将告一段落.总之,可以推想:20世纪30年代新文学史的编纂和新文学作品的选辑,并不是五四全盛时期的硕果,而是人们对轰轰烈烈的五四运动的深切留恋,<中国新文学大系>尤其可以算是为了已结束的文化时代,也为了自己一代人所作出的贡献而建立的一座纪念碑. 相似文献
