Environmental identity formation in nonformal environmental education programs

This paper explores experiences that remained salient in the memories of former participants in three nature-based programs in Colorado, five to forty years after childhood involvement. Interviews with program founders and staff, archival research, and observations of current activities provided an understanding of each program’s history, mission and educational approach. In this context, 18 former participants were interviewed about program experiences that they remembered and program impacts on their environmental identities and academic or career choices. Results were analyzed through the lens of social practice theory, which has significant implications for the design and evaluation of environmental education programs. Results showed that social practice theory is a useful framework for interpreting the development of a social environmental identity, but an ecological identity that forms through direct contact with the natural world is an important complementary concept.     

《文史通义·原道》篇发微

求学以明道也是章学诚的为学目的 ,对道的新认识与其学术理论方法的建立关系重大。道为立言之本 ,道不离器是六经皆史论的立论根据。对闻道的重视也使他在为学方法上迥异于时人 ,而偏重对义理的探究。而《文史通义 .原道》篇是其对道的论述的集中体现。     

邓小平论国际共运的历史启示

没有党的领导就不可能有国际共产主义运动，中国问题的关键在于共产党要有一个好的政治局，特别是好的政治局常委会，只要这个环节不发生问题，中国就稳如泰山。国际共产主义运动没有中心，各国的事情一定要尊重各国的党和人民，不能由别的党充当老子党去发号施令。要对社会主义和马克思主义有清楚的认识，社会主义是个很好的名词，但是如果搞不好，不能正确理解，不能采取正确的政策，那就体现不出社会主义的本质。把马克思主义的普遍真理同我国的具体实际结合起来，走自己的路，建设有中国特色的社会主义，是我们总结长期历史经验得出的基本结论。社会主义经历了一个长时期发展后必然代替资本主义，这是社会历史发展不可逆转的总趋势。但道路是曲折的，坚信世界上赞成马克思主义的人会多起来的，因为马克思主义是科学。

概念图在初中《科学》复习课教学中应用的探索与实践

概念图是一种能形象表达命题网络中一系列概念含义及其关系的图解。近年来,我国的中小学在应用概念图开展教学方面进行积极的实践并取得了较好的效果。主要将结合概念图在初中《科学》复习课教学中的应用从概念图的基本要素、建立的基本步骤方法和对概念图的评价这3个方面展开论述。     

新授课中词汇教学环节设计策略

小学英语教学中无论使用何种教材,在新授课中都会面对词汇的教学,如何合理地设计教学环节是每位英语教师都要思考的问题.学生能否掌握词汇部分之后的句型、段落、篇章等内容,很大程度上取决于词汇教学环节设计策略.     

职业技术教育的质量评估:国际经验与趋势

在我国职业技术教育驶入规模扩张的良性轨道之后,职业技术教育的质量保障和提高已经成为核心问题.在国际上,进行质量评估认证是保障和提高职业技术教育质量的最为重要手段.美国、德国和日本在职业技术教育的质量评估认证体制、标准和程序上都积累了大量经验,包括双层认证体制、基准性标准体系和周期性复审制度.随着宏观环境的变化,美、德、日三国职业技术教育质量评估也表现出一些共性趋势:外部评估与内部质量管理有机结合,质量评估与政府财政资助挂钩,质量评估与从业资格获取密切对应.     

Adverse childhood experiences and deleterious outcomes in adulthood: A consideration of the simultaneous role of genetic and environmental influences in two independent samples from the United States

BackgroundAdverse childhood experiences (ACEs) are a potent risk factor. Despite these findings, studies have also recognized the importance of considering additional sources of genetic and environmental influence that cluster within families.ObjectiveTo properly control for latent sources of genetic and within-family environmental influences and isolate the association between ACEs and the following outcomes in adulthood: physical health, depressive symptoms, educational attainment, income attainment, alcohol problems, and antisocial behavior.Participants and SettingTwo independent samples of twins and siblings from the United States: the Midlife Development in the United States (MIDUS) study (N = 862) and the National Longitudinal Study of Adolescent to Adult Health (Add Health; N = 3112).MethodsSibling comparison models, which control for latent sources of genetic and within-family environmental influences, were estimated to examine whether differential exposure to ACEs was associated with the examined outcomes.ResultsFamilies that experienced more adversity also experienced more deleterious outcomes. However, siblings that experienced more adversity were no more likely to experience deleterious outcomes than their co-siblings. However, greater exposure to ACEs was associated with increases in depressive symptoms (Add Health). Additional models revealed that the similarity between siblings from the same family stemmed from latent sources of within-family environmental influences not captured by traditional ACEs measures.ConclusionsConsidering genetic influences and additional latent sources of within-family influences is crucial in isolating the effects of ACEs. Currently employed ACEs measures may not adequately capture the full range of impactful sources of family-level environmental influence.
