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

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.     

Community implementation outcomes of Attachment and Biobehavioral Catch-up

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.

关于《国际商法》课程实施双语教学的思考

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。     

Sexual Health Equity in Schools: Inclusive Sexuality and Relationship Education for Gender and Sexual Minority Students

ABSTRACT

This paper offers a review of school-based sexuality and relationship education as it relates to gender and sexual minority (GSM) students. Framed by a queer theory lens, the paper examines four main topics: (a) sexual health and relationship risks for GSM youth, (b) comprehensive school-based sexuality education as a protective factor for sexual health and relationship risks, (c) the current availability of relevant sexuality education for GSM students in the United States, and (d) inclusive schools as a social determinant of health. The author advocates for health equity, and offers suggestions for inclusive, comprehensive sexuality and relationship education to provide relevant, accurate, positive information for all students.

快速城市化地区耕地流失的时空特征及其驱动机制综合分析——以江苏省苏锡常地区为例

基于遥感影像、社会经济统计数据及地理空间数据,以耕地流失显著的江苏省苏锡常地区为例,在分析耕地流失时空特征的基础上,不仅剖析了驱动耕地数量减少的宏观政策与社会经济因素,还重点研究了影响耕地流失格局的微观空间因子。研究结果表明:①研究区耕地数量经历了快速减少-缓慢减少-加速减少的变化轨迹,这与不同时期国家宏观政策的重大调整紧密相关;1990-2010年间耕地流失总量为24.46万hm2,主要流向为建设用地与水库坑塘;②城镇人口的激增和区域经济的飞速发展,是驱动研究区耕地数量锐减的主要社会经济因素;③高程因子、距离与交通通达因子、邻域因子均不同程度影响耕地流失的空间格局,其中占主导的是到中心城区的距离、交通便利性以及邻域效应的驱动作用;④未来区域规划应考虑通过产业布局调整和区域整体规划以促进城乡社会经济的协调发展,同时还应重视提高工矿用地以及与三产相关的建设用地的集约利用水平,促进耕地资源开发的合理、有序。
