Modelling the long-run learning impact of the Covid-19 learning shock: Actions to (more than) mitigate loss

This paper uses a calibrated “pedagogical production function” model to estimate the potential long-term losses to children’s learning from the temporary shock of Covid-19 related school closures. It then models possible gains from two mitigation strategies. Without mitigation, children could lose more than a full year’s worth of learning from a three-month school closure because they will be behind the curriculum when they re-enter school and will fall further behind as time goes on. Remediation when children return to school reduces the long-term learning loss by half, but still leaves children more than half a year behind where they would have been with no shock. Remediation combined with long-term reorientation of curriculum to align with children’s learning levels fully mitigates the long-term learning loss due to the shock and surpasses the learning in the counterfactual of no shock by more than a full year’s worth of learning. Systems need to begin planning now for remediation programmes, and as they do so they should build programmes and train teachers in ways that can continue to produce benefits beyond the period immediately following reopening.     

Discrete Choice Modeling in Education: An Innovative Method to Assess Teaching Practices

Self‐reported measures are an easy, time‐efficient, and low‐cost way to collect research data compared to other assessment methods. They are, however, characterized by several limitations regarding the quality and the clarity of the data they produce, especially when they are implemented in education. The main purpose of the current study was to use a method called discrete choice modeling (DCM) in education, in order to develop a self‐reported instrument that will reduce the bias for socially desirable responses and to assess teachers’ practices in physical activity. DCM method has the ability to overcome the respondents’ tendency to answer in a socially desirable way. A nationally representative sample of 531 Greek early educators participated in this study and were administered a self‐assessment questionnaire based on DCM. Results showed that the DCM based newly developed instrument manages to assess effectively educators’ practices and provided evidence of the applicability of the method in education. Further implications and future recommendations regarding the effective application of DCM in education are discussed.     

Evaluating the international dimension in an undergraduate curriculum by assessing students’ intercultural sensitivity

This formative, outcome-oriented, theory-based evaluation research study assessed the effectiveness of requiring an international (‘I’) course by measuring students’ intercultural sensitivity (IS) at the start and end of a semester. Findings revealed that students’ IS scores did not change regardless of the type of class in which the student was enrolled and were not significantly different based on gender, age, ethnicity, undergraduate classification, or number of ‘I’ courses taken. There were significant differences in IS based on religion, traveling outside the US, participating in a study abroad course, and the number of cultural events in which the student had participated. Regression analysis confirmed that religious affiliation and number of times traveled outside the US were significant predictors of IS. This study is an example of the use of theory-based evaluation in an educational system and provides important insights into what experiences affect college students’ IS.

欧洲阅读联盟(EURead)推广阅读活动与启示

[目的/意义]欧洲阅读联盟是欧洲社会力量开展阅读活动的母平台，联盟成员所开展的阅读活动既有差异，也有共性，社会影响力大。通过对欧洲阅读联盟成员所办阅读活动及其规律的分析，可为我国公共图书馆主导与开展阅读活动提供借鉴。[方法/过程]概述欧洲阅读联盟，对其成员类型进行解析，并对每一成员的阅读项目进行共性分析，凝练出阅读活动的经验及规律。[结果/结论]我国应建立多级阅读推广力量，建立政府购买阅读服务长效机制，开放图书馆的阅读活动空间，提升阅读活动频率，开发多样化、差异化的阅读活动。     

图书馆科普教育现状与发展路径探究——基于25个省市88家科普教育基地调查

[目的/意义] 图书馆肩负着实施科普教育的法定职责，拥有品种多样、内容丰富的科普文献与信息资源的图书馆，在开展科普教育方面具有得天独厚的优势。图书馆科普教育起步比较早，2005年，中国图书馆学会成立科普与阅读指导委员会；但在图书馆业界，科普教育只是零星的点缀式服务创新探索，尚未成为常态化服务项目。在依法治馆、创新发展的新时代，寻求图书馆科普教育发展路径具有较强理论和实践意义。[方法/过程] 通过互联网、微信等社交网络平台，对图书馆科普教育基地建设的状况进行调研，从基地等级、基地类型、基地数量、区域分布、有效期限以及认定依据等方面进行深入分析，并对图书馆实施科普教育提出发展路径以供选择。[结果/结论] 图书馆科普教育应坚持基地建设与科普服务相结合、阅读推广与全民科普相融合、科普与游学并举等策略，走设施、资源、服务"三位一体"的持续稳健协调发展之路。     

A Bioethos for Bodies: Respecting a Priceless Resource

The value that willed body donors provide to medical education is priceless. Their precious gift helps to teach anatomy, spatial relationships between morphological structures, anatomical variation, and professionalism to medical students in a way that plastic models, podcasts, and lectures cannot. They are also an important resource for medical research and a wide variety of postgraduate training opportunities. While many body donation programs throughout the world are nonprofit organizations, there are body donation companies in the United States that sell donors for-profit. These “body brokers” have accumulated large profits from this business. It is incongruous that others would profit from such a priceless, freely donated gift. To prevent this incongruity, it is proposed that the international anatomical community develop a normative culture (a bioethos) for body donation programs. This would involve the conscious and systematic development of ethical principles for the day-to-day policies and practices of institutions that collect and use human bodies. With the development of this bioethos, a cultural shift in how donors are treated would occur and, over time, this would become the normal practice. These principles would become fundamental and foundational for the procurement and use of priceless human tissues.

乒乓球运动员膝关节损伤机制研究——对3种常用步法的膝关节负荷特征分析

目的:了解不同性别乒乓球运动员完成并步、跳步、跨步3种常用步法时膝关节的负荷特征,并探析乒乓球运动员膝关节的损伤机制。方法:对乒乓球男、女各10名运动员完成3种常用步法动作时的下肢运动学、动力学数据进行采集和处理,并运用方差分析法比较不同性别、不同技术之间的差异。结果:受试者在完成3种步法过程中,膝关节屈角大致范围在20°~60°。当地面反作用力最大时,女运动员比男运动员表现出更小的外展角(P<0.05),跳步比并步和跨步表现出更小的外展角(P<0.05);在三维受力方面,膝关节受到垂直方向上的力最大,水平向后和向左的力次之,未表现出显著的性别差异和技术差异;在三维力矩方面,膝关节受到的伸膝力矩较大,也未表现出显著的性别差异和技术差异。结论:膝关节屈曲状态下,较大的地面反作用力和膝关节外展角易导致乒乓球运动员前交叉韧带损伤,女运动员的损伤风险小于男运动员,跳步的损伤风险小于并步和跨步;水平向后和向左的力易造成乒乓球运动员软骨和半月板损伤;过大的伸膝力矩易导致乒乓球运动员髌腱末端病和髌骨软化。
