信息化教学创新理论和实践服务乡村教师跨越式教学--专访北京师范大学何克抗教授

何克抗教授及其团队致力于教师专业发展研究20多年,形成了“基础教育跨越式发展创新试验研究”项目(简称“跨越式试验研究”项目)。该项目通过创新信息化教学理论、模式、技术、方法推动教师专业发展,尤其在乡村教师专业发展方面取得了显著的成绩。其关键在于用“4+2”信息化教学创新理论武装乡村教师。所谓“4+2”理论,其中的“4”是指“创造性思维理论、新型建构主义理论、信息技术与课程深层次整合理论、新型教学设计理论”;其中的“2”是指儿童思维发展新论和“语觉论”(即儿童语言发展新论)”。2020年7月,教育部等六部门发布《关于加强新时代乡村教师队伍建设的意见》,恰逢“跨越式试验研究”项目推行20周年。何克抗教授提出用“4+2”信息化教学创新理论和实践模式指导和培训乡村教师,创新教师教育模式,探索新时代中国特色乡村教师发展之路;推行“跨越式试验研究”项目,倡导构建新型的“教师主导与学生主体相结合”的乡村学校课堂教学结构,提出“向课堂40分钟要质量”,关注“跨越式教学”的实际成效;聚焦乡村教师专业发展,推动“4+2”信息化教学创新理论在乡村落地,赋能乡村教师队伍,为新时代乡村教师队伍建设提供卓有成效的服务和大力支持。     

实验经济学研究(专题讨论)

[提要]马涛、李绍东认为,实验经济学研究的是人的行为,但人的行为是复杂的,实验的结果同参与人的文化程度之间有着密切的联系,因此,它需要建立在人文关怀的基础上才可能更趋合理;而这正是实验经济学方法论面临的难题。郭建斌认为,尽管现在就判断实验经济学能否如边际主义那样在经济学各领域引发革命还为时尚早,但它对经济学的证伪主义方法论无疑将产生积极的影响。周星则指出,实验经济学在中国的发展,要更加注重对经济发展和制度变迁等动态性问题的研究,要能为中国经济体制改革提供一个完整的理论说明。     

内混式油喷嘴流量特性实验研究

以压缩空气和变压器油为工质,对内混式介质雾化喷嘴的流量特性进行了实验研究,得出了内混式介质雾化喷嘴油、气流量系数与运行及结构参数的实验关系式.实验结果表明,不同内混式喷嘴或同一喷嘴在不同运行参数下的流量系数值变化很大,与通常设计计算时的推荐值偏差最大达100%以上.油压大于等于气压工况下的实验关系式与油压小于等于气压工况下的实验关系式有较大的区别.     

Promoting Fathers' Engagement With Children: Preventive Interventions for Low‐Income Families

Few programs to enhance fathers' engagement with children have been systematically evaluated, especially for low‐income minority populations. In this study, 289 couples from primarily low‐income Mexican American and European American families were randomly assigned to one of three conditions and followed for 18 months: 16‐week groups for fathers, 16‐week groups for couples, or a 1‐time informational meeting. Compared with families in the low‐dose comparison condition, intervention families showed positive effects on fathers' engagement with their children, couple relationship quality, and children's problem behaviors. Participants in couples' groups showed more consistent, longer term positive effects than those in fathers‐only groups. Intervention effects were similar across family structures, income levels, and ethnicities. Implications of the results for current family policy debates are discussed.     

Cyborg Writing as a Political Act: Reading Donna Haraway in Organization Studies

Extending the works of scholars who have elucidated writing as the quintessential site for social transformation, the aim of this article is to locate the myriad possibilities for actualizing Donna Haraway's concept of cyborg writing in the field of organization studies. I contend that cyborg writing functions as a discursive mechanism by which to disrupt Enlightenment ideals of Cartesian duality, objectivity and rationality. These ideals inform the very structure of masculine privilege that emerge from having a society that is organized along androcentric values. Situating the scholarship of Jo Brewis, a contemporary scholar in the field, I illuminate how cyborg writing can be practised effectively, whereby greater richness is imparted into conceptualizations of, and theorizing on, organizational and management phenomena. I conclude with a discussion of the implications of cyborg writing, and with the identification of two trajectories that scholars can pursue in future studies. Progress along these two paths will move towards actualizing the feminist project for gender egalitarianism.

Evaluation of an intervention supporting breastfeeding among late-preterm infants during in-hospital stay

BackgroundLate-preterm infants show lower breastfeeding rates when compared with term infants. Current practice is to keep them in low-risk wards where clinical guidelines to support breastfeeding are well established for term infants but can be insufficient for late-preterm.ObjectiveThe aim of this study was to evaluate an intervention supporting breastfeeding among late-preterm infants in a maternity service in the Basque Country, Spain.MethodsThe intervention was designed to promote parents’ education and involvement, provide a multidisciplinary approach and decision-making, and avoid separation of the mother-infant dyad. A quasi-experimental study was conducted with a control (n = 212) and an intervention group (n = 161). Data was collected from clinical records from November 2012 to January 2015. Feeding rate at discharge, breast-pump use, incidence of morbidities, infant weight loss and hospital stay length were compared between the two groups.ResultsInfants in the control group were 50.7% exclusive breastfeeding, 37.8% breastfeeding, and, 11.5% formula feeding at discharge, whereas in the intervention group, frequencies were 68.4%, 25.9%, and 5.7%, respectively (p = 0.002). Mothers in the intervention group were 2.66 times more likely to use the breast-pump after almost all or all feeds and 2.09 times more likely to exclusively breastfeed at discharge. There were no significant differences in morbidities and infant weight loss between groups. Hospital stay was longer for infants who required phototherapy in the intervention group (p = 0.009).ConclusionThe intervention resulted in a higher breastfeeding rate at discharge. Interventions aimed to provide specific support among late-pretem infants in maternity services are effective.
