学术自由性与受控性的对立统一——学术自由大学本质观的重新审视

学术自由的大学本质观的应然诉求所产生的大学改革中的悖论,引发了人们对大学本质观的重新审视。对大学的内外环境进行分析及对大学发展历史与现实的考察可以看到,大学的本质是学术自由性与受控性双重属性的对立统一,这是一种基于对大学实然状态的分析所得出的全面辩证的大学本质观。这种大学本质观所揭示的学术自由性和受控性对立统一的矛盾运动,构成了大学存在与发展的根据和原因。处理好自由性与受控性的关系是推动大学改革发展的应然诉求。     

人才培养模式的顶层设计和目标平台建设

按照科学发展观来进行人才培养模式的顶层设计,是高校提高质量的首要问题。人才培养模式的设计通常分为三个层面:学校层面、专业层面和课程与教育教学活动层面。前两个层面具有全局性和综合性,其设计属顶层设计。人才培养模式的顶层设计,首先要分析目标需求及来源,科学确立目标框架,然后对目标进行合理分解和解释,选择合适的内容形成培养方案,最后对目标进行反馈评价,以此不断改进和完善设计。     

Relations of Children's Effortful Control and Teacher-Child Relationship Quality to School Attitudes in a Low-Income Sample

RESEARCH FINDINGS: The purpose of this study was to examine the relations of children's effortful control and quality of relationships with teachers to school attitudes longitudinally in an ethnically diverse and economically disadvantaged sample. Data were collected as part of a larger intervention project during mid-fall, winter, and late spring (ns = 823, 722, and 758, respectively) for 2 cohorts of 3- to 5-year-olds (collected during 2 different school years). Children's effortful control was assessed in the fall with parents' and teachers' reports and 2 behavioral measures. Teacher-child relationship quality was assessed mid-year with teachers' reports of closeness and conflict. Attitudes toward school were assessed in late spring using teachers' and students' reports of school avoidance and liking. Effortful control, in general, was positively correlated with teacher-child closeness and school liking and negatively correlated with conflict and school avoidance. Using structural equation modeling and controlling for sex and ethnicity, we found that effortful control was positively related to teacher-child relationship quality, which in turn was positively related to school attitudes. Furthermore, the relation of effortful control to school attitudes was mediated by teacher-child relationship quality. PRACTICE OR POLICY: Results provide evidence for the importance of relational processes that take place within the classroom context and have implications for teachers and clinicians working to increase school success in ethnic minority and low-income children.

道德教育的根本作为:引导生活的建构

道德教育的根本使命是成人。回归生活的德育要回归于人自身,而生活则是建立在实践基础之上的人之特殊生命活动。德育所回归的人是在生活实践中与他人、他物发生相互关系和作用的人,不是静止、孤立的实体。生活是人自己建构起来的,生活建构的结果,外在表现为生活方式,内在表现为人之品性。人就是他自己生活建构的结果,由是,生活论德育不是将人之至善追求诉诸孤立的人性改造,而是奠基于现实生活的改变。道德教育的根本作为就是引导生活的建构,它所指向的是更有利于人之生成和发展的好生活。道德教育要帮助学习者学会关注、反思、改变生活,提高他们的生活建构的品质和能力。
