The notion that the stories of our lives shape dispositions towards imagined futures is another lens through which university underrepresentation should be viewed. A storied lens attends to how futures, like university attendance, are storied during childhood to the extent that some youth imagine, and therefore plan, these futures as natural progression. Such was the case for study participants, indicating that childhood stories contain answers for mitigating social reproduction connected to parental education and cultural forces within the home. Examining social mobility through the underexplored storied-futures grand narrative presents unique solutions that lay hidden within the dominant meritocratic grand narrative.  相似文献

为了有效促进学生武术核心素养的培育,针对我国武术教学中存在套路内容“繁难”、教法单一、重“形”轻“击”、重知识灌输,轻自主性培养、重教师的“教”,轻学生的“学”“学生不喜欢武术课”等一系列问题,提出了有效促进武术认知、武术运动能力、武术人格培育的原则,基于此原则,对“化难为易”策略、“化浅为深”策略、“化无趣为有趣”策略、“化技术为实践”策略、“知新温故”等策略进行了具体探索性设计,并对上述策略的具体实施方法进行了阐述,为中小学武术教学改革提供现实指导。  相似文献

We extend previous theoretical and empirical work by examining the role that emotions and epistemic judgments play when learning from different refutation plus persuasive and expository plus persuasive texts. We examined how variations in messages designed to change misconceptions and attitudes about genetically modified foods (GMFs) might differentially impact the extent to which individuals engage in epistemic judgments; the emotions individuals experience during learning; and, how epistemic judgments and emotions might facilitate or constrain conceptual and attitudinal change. One hundred twenty-five undergraduate university students were randomly assigned to one of four text conditions: refutation plus positive persuasive text, refutation plus negative persuasive text, expository plus positive persuasive text, or expository plus negative persuasive text. Students were asked to think and emote out loud during learning to capture epistemic judgments and emotions as they occurred in real time. After the learning session, students also self-reported the emotions they experienced during learning. Results revealed that students who were given positive persuasive texts experienced more positive emotions (both intensity and frequency) during learning, whereas those who were given negative persuasive texts experienced more negative emotions (frequency) during learning. Students who were given positive persuasive texts engaged in more epistemic judgments and changed more misconceptions about GMFs compared to students in the other three text conditions. Finally, epistemic judgments were significant positive predictors of conceptual and attitudinal change, and both positive emotions and negative emotions predicted attitudinal change. Implications for theories of conceptual and attitudinal change are discussed.  相似文献

Using PISA and PIAAC data from twelve OECD countries, we examine the gap in cognitive skills among immigrants and natives and evaluate how those differences have evolved over time. We also consider how demographics, family background and school quality explain the development of cognitive skills of young people with immigrant backgrounds. The results show, first, that some convergence in skills occurs between second-generation immigrants and natives over time. Second, demographics, family background and school quality variables all contribute to the achievement gaps across different groups.  相似文献

Social Networking Sites (SNSs) play an important role in our daily lives and the number of their users increases regularly. To understand how users can be satisfied in the complex digital environment of SNSs, this study examines how motivations and emotions combine with each other to explain high satisfaction. Users’ motivations comprise four attributes, entertainment, information, social-psychological, and convenience. Emotions are divided into their two main categories, that is positive and negative emotions. We draw on complexity and configuration theories, present a conceptual model along with propositions and perform a fuzzy-set qualitative comparative analysis (fsQCA). Through an empirically study with 582 SNSs users, we present eight combinations (configurations) of motivations and emotions that lead to high satisfaction, which highlight the role of high convenience, followed by entertainment and information motivations in being satisfied with SNSs. High satisfaction can be achieved both when positive and negative emotions are high and low, depending on how they combine users’ motivations. None of the factors are indispensable to explain high satisfaction on their own, instead they are insufficient but necessary parts of the causal combinations that explain high satisfaction. This study contributes in SNSs literature by extending current knowledge on how motivations and emotions combine to increase satisfaction, and by identifying specific patterns of users for whom these factors are important and influence greatly their satisfaction.  相似文献
