Given multivariate data, many research questions pertain to the covariance structure: whether and how the variables (e.g., personality measures) covary. Exploratory factor analysis (EFA) is often used to look for latent variables that might explain the covariances among variables; for example, the Big Five personality structure. In the case of multilevel data, one might wonder whether or not the same covariance (factor) structure holds for each so-called data block (containing data of 1 higher level unit). For instance, is the Big Five personality structure found in each country or do cross-cultural differences exist? The well-known multigroup EFA framework falls short in answering such questions, especially for numerous groups or blocks. We introduce mixture simultaneous factor analysis (MSFA), performing a mixture model clustering of data blocks, based on their factor structure. A simulation study shows excellent results with respect to parameter recovery and an empirical example is included to illustrate the value of MSFA.  相似文献

Little research has investigated factors that facilitate beginning teachers’ participation in professional learning activities related to differentiated instruction (DI). This study examines environmental factors for DI learning activities in a sample of 272 beginning teachers from 72 primary schools. Multilevel analyses show that teacher education, reflective dialogue, deprivatized practice, educational type, and diversity in student population are related to beginning teachers’ use of DI learning activities (i.e., learning in interaction and changes in practice). As such, the findings revealed that beginning teachers’ participation in such activities may depend on a multitude of factors. Several suggestions regarding these factors are made. First, teacher education can provide foundational knowledge of DI applications. Second, schools can enable teachers to have in-depth conversations with colleagues and provide opportunities to observe good teaching practices. Lastly, alternative schools and schools with diverse student populations can inspire other schools to enhance participation in DI learning activities.  相似文献

School self-evaluation (SSE), as an important leverage for quality assurance, often relies on surveys among staff members to collect information on the schools’ functioning. The extent to which respondents cognitively process items as developers intended them determines the cognitive validity of SSE results. However, it is unclear what problems occur in respondents’ cognitive processes which lead to cognitively invalid SSE results and how respondents’ positions in the school affects these cognitive processes. This study draws on cognitive interviews conducted with 20 teachers and principals to understand their thinking process while answering an SSE survey. Cognitively invalid results were analysed using a content analysis to identify problems in respondents’ cognitive processes. Findings showed that respondents experience semantic and syntactical issues when interpreting items. While elaborating, problems were found regarding items’ topic and focus, particularly concerning whom to make a statement about. Issues also emerged in the response stage, especially that the ‘don’t know’ option was not used as intended. Respondents’ positions influence their understanding about whom a statement is required and how self-evident some items are to them. These problems should be taken into account by developers of SSE surveys and other instruments that intend to measure organisational characteristics.  相似文献

The characteristics of a set of software tools developed for teaching are exposed in this work. This package is designed for telecommunication engineering students in order to facilitate the study of applied electromagnetism and communication theory concepts: theoretical guided propagation, practical training in radiation and radiocommunication laboratory. The programs are made under a MATLAB environment which provides great capabilities for graphical purposes. The programs are designed as user-friendly and interactive tutorials and they can be used as a powerful tool for improving the teaching process.  相似文献

Students entering higher education need to integrate themselves into a new study community. Those coming from minority ethnic backgrounds may experience this phase more intensely since they may feel themselves to be different or consider that they are being treated differently. This article approaches ethnic identity as a dynamic concept. The differences characterizing students with varying ethnic self‐definitions are explored as subjective factors that are important for good study progress. Finally, study progress after one year is analyzed.  相似文献

农业资源 法是我国资源法体系的重要组成部分。当前,农业资源立法采取的是以自然资源构成要素为法律调整对象的立法模式,主要确立了权属、调查评价、规划、保护和许可审批制度,仍处于单项法律、法规为主的群法状态。法制体系不健全、内容不完善、与市场经济的经济运行机制农业资源、法律制度  相似文献

本文首先对国际反倾销现状进行了分析,结果表明国际反倾销近30年来愈演愈烈,尤其是对华反倾销的地位在急剧上升,究其原因是什么吗?作者建立了一个完全信息反倾销对抗博弈模型对此给予了理论解释,并经实证分析指出了在国际反倾销浪潮中我国少有对外反倾销申诉的成因,主要是专职管理投入不足、产业集中度低和不擅长反倾销博弈等,文末指出模型在许多领域具有普遍的拓展应用前景,可以类推解释许多对抗博弈问题。  相似文献
