Accurate teacher evaluations of student performance are crucial for effective teaching. This study examined whether students’ immigration and language background affect teachers’ evaluations. Multilevel analyses tested whether teachers overestimate the performance of immigrant relative to that of non-immigrant students. As part of the German PISA 2003 assessment, 305 teachers predicted the performance of seven of their students on two mathematics problems of different linguistic complexity. Results revealed an interaction effect of students’ language background and linguistic complexity of the problem on teachers’ predictions. Teachers overestimated the performance of bilingual students more than the performance of monolingual immigrant or non-immigrant students on a linguistically complex problem. Teachers need to consider both students’ language background and linguistic demands of the material used to appropriately support bilingual students. 相似文献

This study investigates factors in the home environment and their influence on children’s analytical, creative, and practical skills. A sample of 294 gifted children (195 male) was recruited from grades 4–7 in Saudi Arabia, where the family context is highly influenced by the principles of Islam. Results did not confirm the effect of birth order, but showed that (1) mother’s education was an important factor for gifted children’s creativity; (2) the number of boys in the family was negatively associated with gifted boys’ creativity (r?=??.21); and (3) Quran-related learning experiences were positively related to gifted girls’ analytical (r?=?.46) and creative (r?=?.42) skills. Implications for understanding non-Western environments for gifted children are discussed. 相似文献

Foreign firms patent in emerging economies with weak appropriability regimes at an increasing rate. This phenomenon constitutes a paradox since in such a setting foreign firms should have weak incentives to patent. In an attempt to resolve this paradox, we conducted an inductive analysis of 11 foreign firms that patent in such a setting, using the case of China as our empirical context. We identify four archetypes of foreign firms and three key antecedents the interaction of which determines which archetype a firm can be subsumed under.Our study complements the developed-economy focus of the extant appropriation literature by adding an international perspective. We extend previous econometric studies by identifying salient factors on the firm level that determine the extent to which a foreign firm patents in emerging economies with a weak appropriability regime, highlighting that the extent of a firm's motivation to maintain its freedom to operate can supersede imitability concerns. We also comment on the practical implications of these contributions for managers of foreign firms. Highlighting a structural conflict of interest between foreign firms from developed economies and the development goals of an emerging economy, we point to the generalizability of our results to a wide range of other emerging economies worldwide. 相似文献

Despite the importance of scientific inquiry in science education, researchers and educators disagree considerably regarding what features define this instructional approach. While a large body of literature addresses theoretical considerations, numerous empirical studies investigate scientific inquiry on quite different levels of detail and also on different theoretical grounds. Here, only little systematic research has analysed the different conceptualisations and usages of the overarching construct of scientific inquiry in detail. To close this gap, a review of the research literature on scientific inquiry was conducted based on a widespread approach to defining scientific inquiry as activities that students engage in. The main goal is to provide a systematic overview about the range and spectrum of definitions and operationalisations used with regard to single activities of the inquiry process in empirical studies. The findings from the review first and foremost illustrate the variability in the ways these activities have been operationalised and implemented. For each activity, studies differ significantly not only with respect to the focus, explicitness and comprehensiveness of their operationalisations but also with regard to the consistency of their implementation in the form of instructional or interventional components in the study and/or in the focus of the assessment of student performance. This has significant implications regarding the validity and comparability of results obtained in different studies, e.g. in the context of discussions concerning the effectiveness of inquiry-based instruction. In addition, the interrelation between scientific inquiry, scientific knowledge and the nature of science seems to be underexplored. The conclusions make the case for further theoretical work as well as empirical research. 相似文献

Teaching quality often is assumed to be a personal and stable characteristic of teachers. Whether this is true has scarcely been investigated empirically. In this study the extent to which value-added scores of teachers teaching German and English as a foreign language (EFL) to the same class remain consistent across subjects was investigated. Then, the consistency of two teaching quality dimensions—classroom management and motivational support—across subjects was explored. A sample consisting of 25 classes with 548 students to whom German and EFL were taught by the same teacher was analyzed using multivariate multilevel models and generalizability theory. The results showed that the value-added scores were highly correlated across subjects. While there was hardly any subject-dependent variance in classroom management, there was substantial subject-dependent variance in motivational support. The results indicate that it is important to conduct further studies on the situational and contextual factors that might influence teaching quality to gain a more comprehensive picture regarding the consistency of teaching quality across various conditions. 相似文献

Virtual communities like Second Life (SL) represent an economic factor with increasing potential, but may induce behavior that deviates from real-world experience. This article introduces a new experimental design that is based on the trust game (Berg, Dickhaut, & McCabe, 1995), but eliminates the problem of multiple virtual identities. One treatment of the experiment in the virtual world SL was conducted and the results compared to the First Life (FL) control treatment, which was conducted on a university campus. In SL, significantly lower investment levels were found, but significantly higher average returns were found than in the FL treatment or in the literature. It is conjectured that the disparity between trusting and trustworthy behavior is a sign that the social structure in SL is still evolving. It seems plausible that the trustors in a young and developing society cautiously test the extent of trustworthiness, whereas the trustees strategically invest in levels of trustworthiness that are higher than in settled societies to build up a trustworthy environment. 相似文献

ABSTRACTPrismatic refraction is a classic topic in science education. To investigate how undergraduate students think about prismatic dispersion, and to see how they change their thinking when observing dispersed images, five teaching experiments were done and analysed according to the Model of Educational Reconstruction. For projection through a prism, the students used a ‘split image projection’ conceptualisation. For the view through a prism, this conceptualisation was not fruitful. Based on the observed images, six of seven students changed to a ‘diverted image projection’ conceptualisation. From a comparison between students’ and scientists’ ideas, teaching implications are derived for an image-based approach. 相似文献
