ABSTRACT

A main objective of classroom management (CM) is to raise students’ attention to their daily academic work by creating a classroom environment that supports academic and socioemotional learning. While studies have addressed CM effects on classroom-level behaviour or students’ academic outcomes, students’ attention skills been largely overlooked. This randomized controlled trial evaluates the effectiveness of a teacher-targeted CM intervention on students’ selective attention. Twenty-four primary schools were randomized into receiving the Inclusive And Appreciative Classroom Management (IACM) intervention (treatment) or a general information technology (IT) didactics course (control condition). All participating 1st-grade teachers and their students (N = 1,160) were followed for 1 year. Using repeated measurements of the d2 Test of Attention, we find that the IACM intervention improves students’ selective attention with .26 standard deviations. The effect is robust to the inclusion of student- and classroom-level characteristics. All analyses account for the variation across students, classrooms, and schools.  相似文献   

Transcending Library Catalogs: A Comparative Study of Controlled Terms in Library of Congress Subject Headings and User-Generated Tags in LibraryThing for Transgender Books     

《Journal of Web Librarianship》2013,7(4):309-331

Perhaps the greatest power of folksonomies, especially when set against controlled vocabularies like the Library of Congress Subject Headings, lies in their capacity to empower user communities to name their own resources in their own terms. This article analyzes the potential and limitations of both folksonomies and controlled vocabularies for transgender materials by analyzing the subject headings in WorldCat records and the user-generated tags in LibraryThing for books with transgender themes. A close examination of the subject headings and tags for twenty books on transgender topics reveals a disconnect between the language used by people who own these books and the terms authorized by the Library of Congress and assigned by catalogers to describe and organize transgender-themed books. The terms most commonly assigned by users are far less common or non-existent in WorldCat. The folksonomies also provide spaces for a multiplicity of representations, including a range of gender expressions, whereas these entities are often absent from Library of Congress Subject Headings and WorldCat. While folksonomies are democratic and respond quickly to shifts and expansions of categories, they lack control and may inhibit findability of resources. Neither tags nor subject headings are perfect systems by themselves, but they may complement each other well in library catalogs. Bringing users’ voices into catalogs through the addition of tags might greatly enhance organization, representation, and retrieval of transgender-themed materials.  相似文献   

The impact of vouchers on preschool attendance and elementary school readiness: A randomized controlled trial in rural China     

《Economics of Education Review》2013

Although preschool has been shown to improve children's school readiness in many developing countries, preschool attendance in poor rural areas of China is still low. The high cost of preschool is often regarded as a major barrier to attendance. In this paper, we evaluate the impact of a one-year voucher/CCT intervention on preschool attendance and school readiness. To do so, we conducted a randomized controlled trial among 150 young children in a poor, rural county in China. Our analysis shows that the intervention, consisting of a tuition waiver and a cash transfer conditional on attendance, raised attendance by 20 percentage points (or by 35%). However, the intervention did not have measurable impact on children's school readiness. We believe that poor quality of preschool education in rural China (in terms of both teaching and facilities) contributes to our findings.  相似文献

Modeling for the diffusion limitation of free radical polymerization     

Yao Zhen  Li Bo-geng  Cao Kun  Huang Yuan  Pan Zu-ren 《浙江大学学报(A卷英文版)》2000,1(2):148-156

A new model was developed to describe the diffusion limitation on free radical polyme-rization. In this model the termination rate coefficient (k _t) and propagation rate coefficient (k _p) were expressed as a function of bulk viscosity (η). This model was used to simulate the batch thermal polymerization of styrene (St) and the continuous thermal bulk copolymerization of St (monomer 1) and maleic anhydride (MAH, monomer 2) in a CSTR with on-line monitor of the rheological behavior. The simulated results on polymerization conversion, copolymer composition, molecular weight and its distributions were compared with the experimental data, and the results calculated by two previous gel-effect models i.e. Martin-Hamielec and Tulig-Tirrell models. It was found that the present model produces better prediction than that of the Tulig-Tirrell model and has the same accuracy as that of the Martin-Hamielec model, but is much simpler.

Application of network meta-analysis in the field of physical activity and health promotion     

Xiwen Su  Daniel J. McDonough  Haitao Chu  Minghui Quan  Zan Gao 《运动与健康科学(英文)》2020,9(6):511-520

Continued advancement in the field of physical activity and health promotion relies heavily on the synthesis of rigorous scientific evidence. As such, systematic reviews and meta-analyses of randomized controlled trials have led to a better understanding of which intervention strategies are superior (i.e., produce the greatest effects) in physical activity-based health behavior change interventions. Indeed, standard meta-analytic approaches have allowed researchers in the field to synthesize relevant experimental evidence using pairwise procedures that produce reliable estimates of the homogeneity, magnitude, and potential biases in the observed effects. However, pairwise meta-analytic procedures are only capable to discerning differences in effects between a select intervention strategy and a select comparison or control condition. In order to maximize the impact of physical activity interventions on health-related outcomes, it is necessary to establish evidence concerning the comparative efficacy of all relevant physical activity intervention strategies. The development of network meta-analysis (NMA)—most commonly used in medical-based clinical trials—has allowed for the quantification of indirect comparisons, even in the absence of direct, head-to-head trials. Thus, it stands to reason that NMA can be applied in physical activity and health promotion research to identify the best intervention strategies. Given that this analysis technique is novel and largely unexplored in the field of physical activity and health promotion, care must be taken in its application to ensure reliable estimates and discernment of the effect sizes among interventions. Therefore, the purpose of this review is to comment on the potential application and importance of NMA in the field of physical activity and health promotion, describe how to properly and effectively apply this technique, and suggest important considerations for its appropriate application in this field. In this paper, overviews of the foundations of NMA and commonly used approaches for conducting NMA are provided, followed by assumptions related to NMA, opportunities and challenges in NMA, and a step-by-step example of developing and conducting an NMA.  相似文献

Promoting the attitudes of nursing students towards refugees via interventions based on the contact hypothesis: A randomized controlled trial     

《Int J Intercult Relat》2021

A randomized controlled study was implemented on 90 nursing students in Turkey. The sample was divided into two groups: intervention and control group. The intervention group received education on refugee health and participated in a practical internship with refugees. Three scales were administered to the two groups at baseline (pre-test) and the end of intervention (post-test): "Xenophobia", "Attitude Towards Refugees" and "Intercultural Sensitivity". The three scale post-test scores of the intervention statistically significantly differed from control group and showed a statistically significant interaction between the groups and time in the two-way analysis of variance. The three scale post-test scores significantly differed from the pre-test scores in the intervention group, showing more relevant effects on xenophobia scale, two subscales of attitude towards refugees and intercultural sensitivity scale. The interventions based on the contact hypothesis improved nursing students' attitudes towards refugees.  相似文献   

Cultivating the Cooperative: PCC,the Music Library Association,and the Music OCLC Users Group     

Nancy Lorimer 《Cataloging & classification quarterly》2020,58(3-4):361-374

Abstract

PCC and the Music Library Association (MLA) and Music OCLC Users Group (MOUG) have a long history of coordinating and collaborating on standards, best practices, and training of the music cataloging community. The impact of these collaborations on the formation and structure of the PCC is found throughout the organization, particularly in the PCC funnels, but also in the basic concept of a cooperative cataloging community. This article describes some of the MLA and MOUG cooperative efforts that have benefited and influenced the PCC.  相似文献
