School‐wide positive behavior support (SWPBS) is a systemic approach for implementing a proactive schoolwide discipline and for improving students’ academic and behavioral outcomes by targeting the school’s organizational and social culture. With a multilevel approach, the present study evaluates the relative effectiveness of SWPBS on teachers’ perceptions of the student behavior (N = 3,295) across schools, teachers, and children using a multilevel approach. We assessed teacher perception of student problem behavior five times during a 3‐year implementation of SWPBS in 23 Dutch schools. Multilevel analyses not only revealed a small increase in perceived prosocial behavior and a small decrease in problems with peers, but also different effects across children, teachers, and schools. Effects were stronger for girls and for students with higher severity of perceived problems at baseline. At teachers’ level, higher mean baseline severity of perceived problems was associated with the reduced impact of SWPBS on perceived emotional problems and problems with peers. At the school level, effects were stronger for regular schools as compared with special needs schools.  相似文献

驻共产国际时期的王明思想是以“左”倾错误思想为指导的,他宣传世界革命“高涨论”,中国革命“高潮论”,系统地阐发了冒险而教条的主张,给中国革命带来了惨重的损失,但王明在坚持“左”倾思想的同时,随着中国抗日战争形势的发展和共产国际指示精神的变化,在一些方面也适时地调整了政策,提出了比较符合实际的新见解,对全党调整方针政策起到了一定的作用,如在统一战线,东北问题以及反对李立三“左”倾思想等方面阐述了一些可取的思想。  相似文献

ABSTRACT

Evidence exists that American institutions of higher education are well-entrenched in the consideration of mechanisms for supporting the implementation of Open Educational Resources (OER) and alternative textbooks. Literature reveals that developing and implementing OER is a significant undertaking in terms of time and human resources. This study deploys content analysis of a sample of United States regionally based higher education institutional websites to determine the current state of institutional support mechanisms to implementers just embarking on the OER journey. Findings reveal that institutions have made strides in the development of faculty mini-grants and stipends with guidelines, proposal checklists, and weighting mechanisms to inform decision making. However, due to widespread language across the stratified sample emphasising award pool and individual limits, it is clear that OER funding is still seeking wider support as a permanent funded resource. Sponsorship of institutional OER initiatives seems split between institutional library functions and teaching and learning centres. Other issues, such as ownership and licensing, are significantly underdeveloped in field implementation or fall in a large continuum of practices. Recommendations of shared responsibility and use of data driven initiatives are provided that may improve institutional support of faculty OER adoption, adaption and creation.  相似文献

In this work, support vector classification (SVC) algorithm was used to build structure-activity relationship (SAR) model of the 5-hydroxytryptamine type 3 (5-HT3 ) receptor antagonists with 26 compounds. In a benchmark test, SVC was compared with several techniques of machine learning currently used in the field. The prediction performance of the model was discussed on the basis of the leave-one-out cross-validation. The results show that the accuracy of prediction of SVC model was higher than those of back propagation artificial neural network (BP ANN), K-nearest neighbor (KNN) and Fisher methods.  相似文献
