政府与公共图书馆——关于图书馆制度的一种规范分析

公共图书馆是一种典型的公共产品。它的高度正外部性特征,决定了市场提供的非效率性。公共图书馆只能由政府提供,政府必须履行公共图书馆投资主体的责任。为解决公共图书馆的拥挤性和地域性问题,政府必须承担普及公共图书馆的责任,并提供投资保障。图4。参考文献9。     

Strength in Numbers: Encouraging Every Staff Member to Work to Capacity

Libraries play a critical role in enhancing the learning landscape of the schools they support. In order for any library to become a powerhouse and a community meeting place, all library team members need to align with the library's vision, own it and begin to add their own strengths and talents purposefully. This article explores practical strategies for developing a visionary team, including supportive leadership, daily stand-up meetings, weekly staff meetings, special-focus teams, rostering and the “five conversations” approach. These effective strategies can be implemented across a broad range of library workforce contexts in order to ensure the most effective workforce teams are built.     

“But it doesn’t come naturally”: how effort expenditure shapes the benefit of growth mindset on women’s sense of intellectual belonging in computing

Research suggests growth mindset, or the belief that knowledge is acquired through effort, may enhance women’s sense of belonging in male-dominated disciplines, like computing. However, other research indicates women who spend a great deal of time and energy in technical fields experience a low sense of belonging. The current study assessed the benefits of a growth mindset on women’s (and men’s) sense of intellectual belonging in computing, accounting for the amount of time and effort dedicated to academics. We define “intellectual belonging” as the sense that one is believed to be a competent member of the community. Whereas a stronger growth mindset was associated with stronger intellectual belonging for men, a growth mindset only boosted women’s intellectual belonging when they did not work hard on academics. Our findings suggest, paradoxically, women may not benefit from a growth mindset in computing when they exert a lot of effort.

从“固化”到“转型”:基于成长型思维的教师专业发展及其实现

思维方式作为支撑教师专业发展的核心,在某种程度上决定着教师专业发展的深度与高度。在场域型塑、课程固化与工作重复等因素作用下,教师专业发展很容易陷入思维固化。成长型思维的丰富内涵与独特价值,为突破教师专业发展的思维固化提供了转型基础。策略在于:教师需要检视自身的思维方式,切实意识到成长型思维对专业发展的决定作用;动态地调控思维过程,促使专业发展在成长型思维引领下积极前行;敢于直面思维局限,突破专业发展的瓶颈以达到新高度;充分发挥思维的预测功能,对专业发展的未来进行合理规划。

Examining the effect of positive behaviour support on academic achievement of students with disabilities

Students who engage in challenging behaviour compromise the fundamental ability of schools to educate children. Consequently, teachers face the daunting task of designing effective strategies to promote positive educational outcomes for their students. Since the 1997 Individuals with Disabilities Education Act amendments, the use of positive behaviour supports (PBS) to address the behavioural needs of children challenged by disabilities has expanded. There is evidence to support the utility of PBS in reducing challenging behaviour among students. However, successful schools are also gauged by the academic achievement of their students. Hence, it is important to examine the extent to which behavioural outcomes are related to academic outcomes. The purpose of this paper is to examine the extent to which PBS interventions aimed at reducing challenging behaviour result in corresponding improvement in academic achievement. A meta‐analysis of extant research indicated a positive correlation of 0.40 between improvement in problem behaviour and academic achievement.
