The idea that language skills support school readiness, predicting later self‐regulation and academic success, is widely accepted. Although vocabulary is often emphasized in the developmental literature, the ability to use language appropriately in the classroom, or social communication skills, may also be critical. This article examined longitudinal contributions of children's vocabulary and social communication skills, from preschool to kindergarten, to kindergarten academic achievement (reading and math) and self‐regulation (executive functions and learning behaviors). Participants were 164 children (14% Latinx, 30% Black, 56% White; 57% girls) enrolled in Head Start programs. Results revealed that initial levels and growth in vocabulary and communication skills predicted better academic achievement. Social communication skills uniquely predicted self‐regulation, after accounting for vocabulary. We discuss potential mechanisms for these links and recommend that strategies to build social communication skills be incorporated in preschool interventions promoting school readiness.  相似文献

一稿多投是学术界由来已久且难以医治的顽症。究其原因,主要是科研压力之下作者的投机心态、作者投稿经验的匮乏、稿件时效性的压力以及网上投稿的便捷与低成本等因素使然。一稿多投会造成编方人力资源的浪费,容易引发一稿多发,挤占宝贵的版面资源,引起版权纠纷,破坏学术诚信,扰乱科研秩序。要从加强制度建设、加大惩罚力度、利用高科技进行防范、健全监督机制、加强学术道德教育、提高编辑效率等方面,把"他律"与"自律"结合起来,惩防并举,标本兼治,多管齐下,齐抓共管,从根本上规范科研活动,根治一稿多投顽症。  相似文献

我国外国教育史学发展的百年历程经历了萌芽起步、艰难恢复、积极发展、成就与危机并存以及近年来的积极转向这几个阶段。几代学者共同就外国教育史的基本命题进行了深入的讨论、总结与反思,包括外国教育史是什么?研究外国教育史有什么用?作为一个学术领域,外国教育史应该研究什么?怎样研究?作为一个知识门类,外国教育史应该教什么?怎样教?学者们的辛勤耕耘使外国教育史学已经有了一个健康合理的起点,但其中诸多制约外国教育史学发展的实质性问题仍需重视,包括教育史观的把握问题、教育史研究的功利主义问题、教育史研究的规范意识问题以及教育史研究的陈述范式与立场视角的自觉反思问题等。  相似文献

The discourse of some of the most powerful public figures in today’s world is often incoherent and nonsensical. Incoherent yet authoritative discourse shows that authority does not rest in language but results from non‐linguistic and pre‐textual conditions. The non‐linguistic and pre‐textual conditions are exemplified in an Australian case‐study of a media debate between the Immigration Minister and a refugee, drawing on research by Smith‐Khan (2019a, 2019b). Two such conditions are then examined with reference to academic publics. First, I ask which languages do or do not carry authority, before moving on to speaker identity as a condition of authority. The close association between English and academic excellence has resulted in diminishing the authority of academic publications in languages other than English. The same is true of publications by women and people of colour. I close by reflecting on referencing practices as forms of extending authoritativeness to voices in excluded languages and from excluded scholars in academic publics.  相似文献

We examined whether fathers’ residency modified the associations among mothers’ supportiveness, father involvement, children’s negative emotionality during toddlerhood and children’s academic skills in pre‐kindergarten via children’s self‐regulation. Participants were 2,291 mothers (Mage = 23.24 years) and children (Mage = 14.99 months at Wave 1; 50.7% girls) in the Early Head Start Research and Evaluation Project. Results revealed distinctive associations by fathers’ residency: self‐regulation mediated the association between mothers’ supportiveness and academic skills only in resident‐father‐families. Self‐regulation mediated the association between negative emotionality and academic skills only in nonresident‐father‐families. The findings highlight the family processes of mothers, fathers, and children in low‐income family contexts that contribute to children’s academic skills, and how those family processes may vary by fathers’ residency status.  相似文献

We examined the moderating roles of individualistic and collectivistic cultural orientations and academic achievement on the relation between Chinese adolescents’ shyness and depressive symptoms. A sample of Chinese adolescents (N = 492) from an urban school participated in the study during seventh (T1) and eighth (T2) grades. Adolescents self‐reported their shyness, cultural orientations, and depressive symptoms. The school provided records of their academic achievement. Concurrently, shyness and individualism were positively whereas collectivism and academic achievement were negatively, associated with adolescents’ depressive symptoms. Longitudinally, T1 shyness (but not individualism, collectivism, or academic achievement) predicted T2 depressive symptoms after controlling for stability in depressive symptoms. Concurrent relations between shyness and depressive symptoms were moderated by adolescents’ cultural orientations. Specifically, collectivism was protective whereas individualism was harmful, for shy adolescents’ adjustment. Furthermore, collectivism and academic achievement jointly moderated the relations between shyness and depressive symptoms concurrently and longitudinally. The results suggest that cultural orientations may influence shy adolescents’ depression symptoms through individual‐level self‐evaluation, and indicate that cultural factors and academic achievement need to be considered comprehensively for understanding and improving shy Chinese adolescents’ psychological adjustment.  相似文献

This paper explores vulnerable relational knowing, and in it we open up our own embodied habits and experiences as feminist academics. We discuss how displaying our academic bodies as naked, both symbolically and physically, enhances and appreciates—instead of hiding—vulnerability. We also discuss how our academic bodies entangle with a range of more-than-human creatures and material surroundings to highlight the multispecies and material nature of vulnerable relational knowing. Two detailed stories, “Intimate sharing of academic knowledge: A recumbent study circle” and “Keropirtti: A place and space to work differently” provide unique examples of the enactment of alternative ways of working in academia, and their analysis demonstrates the potential of vulnerability for embodied relational knowing in academia, which has, to date, been commonly analyzed in the context of writing.  相似文献

关于高校学报非核心期刊生存与发展的思考   总被引:1,自引:0,他引:1  
高校学报属于学术期刊,是高等学校主办的以反映高校科研和教学成果为主的学术理论刊物。在学术期刊实行核心期刊与非核心期刊的评价机制后,高校学报中的非核心期刊面临着严峻的生存与发展危机。面对困境,学报中的非核心期刊应该在不断提高编辑人员自身素养的前提下,认清发展方向,准确定位,办出特色,不断增强自身竞争力。  相似文献
