Elementary school children’s understanding of science: The implementation of an extracurricular science intervention     

《Contemporary educational psychology》2017

The promotion of students’ achievement and competence in the so-called STEM disciplines is one cornerstone of current educational research and practice. In particular, as early as elementary school, the fostering of an adequate understanding of science is a normative goal of science education. It facilitates students’ science learning and enables them to understand the nature and development of scientific knowledge. Based on the relevance of the promotion of young children’s understanding of science, a corresponding science intervention was recently developed and successfully evaluated in a first study under highly controlled conditions. The goal of the present study was to investigate the effectiveness of this intervention when implemented in practice. One hundred seventeen third- and fourth-grade students and 10 trained course instructors participated in this study. We applied a randomized block design with waitlist control groups and repeated measures. The results revealed that children assigned to the intervention compared with children assigned to the waitlist control group showed better inquiry-related methodological competencies (a better understanding of the scientific inquiry cycle and experimentation strategies) and a higher need for cognition. The findings point to the successful implementation of the intervention and are compared with the results of the first study.  相似文献   

Community implementation outcomes of Attachment and Biobehavioral Catch-up     

《Child abuse & neglect》2016

Bringing evidence-based treatments to community practice is a critical challenge for the field. When implemented in the community, evidence-based treatments often fail to provide the benefits shown in laboratory settings. Therefore, when evidence-based treatments are transported to the community, it is essential to investigate implementation process and outcomes. The present study assessed whether Attachment and Biobehavioral Catch-up (ABC), an intervention for high-risk parents that has been shown to be efficacious in randomized clinical trials (RCTs), changed parent behavior in a community-based setting. This study examined data collected from 78 cases by 9 parent coaches in a diverse community setting in Hawaii, and compared data to benchmarks from RCTs. Parent coach fidelity was coded from intervention session video clips, and was also compared with benchmarks. Caregivers participating in ABC were primarily birth parents, and most were referred through Child Protective Services involvement or for reasons of harsh parenting or neglect. Parental behavior was assessed before and after intervention using a semi-structured play task. Increases in parental following the lead and delight, and decreases in parental intrusiveness, were observed; these changes were comparable to effect sizes observed in RCTs. Intent to treat analyses were conducted using behavioral data from videotaped sessions, and suggested that ABC also improved following the lead in parents who subsequently dropped out of treatment. These results support the viability of ABC for enhancing parenting behavior among parents at high risk for maltreatment, and demonstrate that parent coaches in community agencies can successfully implement ABC.  相似文献

关于《国际商法》课程实施双语教学的思考     

杨成 《辽宁教育行政学院学报》2007,24(1):83-85

为了适应我国对涉外法律人才的需求,本科院校法学专业先后开设了《国际商法》课程。《国际商法》课程实施双语教学,既是课程教学目的和教学要求的需要,也是时代发展对涉外法律人才的需要。为了满足上述两种需要,国际商法双语教学就应有明确的实施思路,使学生通过该课程的学习掌握语言技能,并熟练地运用语言从事专业工作。  相似文献

Does Fidelity of Implementation Account for Changes in Teacher–Child Interactions in a Randomized Controlled Trial of Banking Time?

This study examined fidelity of implementation in a randomized trial of Banking Time, a classroom-based intervention intended to improve children's behavior, specifically for those at risk for developing externalizing behavior problems, through improving the quality of teacher–child interactions. The study sample comes from a randomized controlled trial that took place over three years and included 183 teachers and 470 preschool children recruited across three sites. Results exploring fidelity of implementation indicated that Banking Time practices were present across treatment and nontreatment groups. In addition, the presence of more Positive Banking Time Practices accounted for improvements in teacher–child interactions while Restricted Banking Time Practices showed inconsistent patterns, relating both to positive and negative teacher–child interactions. Further, random assignment to Banking Time resulted in the presence of more Positive Banking Time Practices and fewer Restricted Banking Time Practices, which accounted for the improved teacher–child interactions. Thus, findings point to the critical need to better account for intervention fidelity across conditions in randomized trials, allowing for better understanding of the mechanism through which interventions lead to intended outcomes.  相似文献

One-to-One Computing and Student Achievement in Ohio High Schools     

Nancy L. Williams  Karen H. Larwin 《Journal of Research on Technology in Education》2016,48(3):143-158

This study explores the impact of one-to-one computing on student achievement in Ohio high schools as measured by performance on the Ohio Graduation Test (OGT). The sample included 24 treatment schools that were individually paired with a similar control school. An interrupted time series methodology was deployed to examine OGT data over a period of 5 to 8 years. Overall student performance and content-specific achievement in math, reading, science, social studies, and writing were not significantly affected by the introduction of 1:1 computing. Treatment schools using a netbook device produced the greatest overall change in scores.  相似文献
