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

开展信息化、智慧化预警工作是实现全面精准育人的重要途径,而预警应用平台无疑是预警工作的有力工具和实践载体,其设计方案应用效果的好坏直接决定着学习预警信息化愿景的达成度。文章在分析高职院校学习预警工作现状的基础上,从工作流程设计、平台框架设计和平台建设方法等3个方面提出了解决方案,并对平台的应用效果进行了实证分析,结果表明:平台的应用扩展了预警范围、提升了预警的精准度和时效性、提高了工作效率,且干预更为灵活、个性化,可为当前高职院校学习危机的实践改革提供新思路。  相似文献

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.  相似文献

BackgroundSon preference is an enduring phenomenon in China and may often be related to childhood adverse experiences. According to a life-course perspective, adverse experiences during a childhood period may have a long-term effect on mental health in later age. However, little is known about this relationship between parents’ son preference, childhood adverse experiences and adulthood mental health in China.ObjectiveThe study aims to evaluate the association of parents’ son preference and individual mental health in old age in China. The mediating role of childhood adverse experiences was also estimated.Participants and settingThe China Health and Retirement Longitudinal Study (CHARLS) 2015 combined with CHARLS life history survey was analyzed (N = 11,666).MethodsMental health was measured by a shortened modification of the Center for Epidemiologic Studies Depression scale including seven items, and higher scores indicated worse mental health status. A four-step mediating model was applied.ResultsRespondents growing in families with son preference had on average 0.75 (P < 0.001) points higher on the mental health scale than their counterparts, and the effects were consistent for both males and females. Childhood adverse experiences measured by physical maltreatment, emotional adverse experiences and witnesses of inter-parent violence mediated the relationship between parents’ son preference and individual adulthood mental health by 47.87%. For females, physical maltreatment and emotional adverse experiences explained the most parts of health effects of parents’ son preference, whereas witnesses of inter-parent violence was the most influential mediator for males.ConclusionParents’ son preference led to adverse childhood experiences, which influenced mental health in adulthood.  相似文献

20世纪50年代以来,谈话法就一直是数学教学的主流方法。这种谈话法大多由教师提出问题展开,以师生间一问一答的方式进行,教师提出的问题中具有启发式的,开放式的,需要学生经过深思熟虑才能回答的问题并不多。师生间是单向交流,学生缺少提出问题的机会,很大程度上限制了学生的思考和独立解决问题的能力。在数学教学中培养学生提出问题的能力是我们必须贯彻的教学目标。  相似文献
