This study focused on science and math professional learning communities (PLCs) that were implemented through a university‐urban high school partnership. These PLCs were part of mandated school‐wide, content‐based PLCs implemented as part of the reform efforts initiated in an urban school to address the school's failure to meet Adequate Yearly Progress (AYP) for four years consecutively and low graduation rate (less than 25%) for male students. The key issues were (a) students had continually earned low test scores; (b) there was continuous principal turnover; (c) faculty morale was at an all‐time low, and the quality of teaching was very poor; and (d) the students were not effectively disciplined. The study examined the impact that university faculty‐led mandated PLCs have on teachers' practices and students' learning and achievement. Analysis of data revealed practices that were effective in developing and implementing these successful math and science PLCs. Three themes emerged: ethics of care, teacher agency, and aesthetics of professional interactions. Each theme contained key features that appeared to contribute to the implementation of a successful PLC. 相似文献

高校管理是一项涉及多层面、多要素变量的复杂系统,教育部建立高校评价指标体系对各高校现发展水平进行评价,促进国家教育发展.如何建立科学的评价指标体系?如何提高评价效应已有很多研究.但,未来发展仿真研究很少,因此,进行依据评价指标建立仿真方程、建立可靠性高的仿真模型研究很有意义.本文运用逐树设撤关联数结构行为检验建模法,基于教育部高校评价指标体系建立6个流位流率对构成的流位流率系;分别应用流率历史枝、主撑枝、条件枝法构建6棵流率入树基本结构,基于历史数据建立流率历史枝变量仿真方程;基于教育部高校评价指标的内涵等式建立刻画未来发展的主撑枝变量的仿真方程,基于表函数、延迟函数等建立条件枝变量仿真方程;通过设撤关联数分别进行T1(t)、T1(t)T2(t)、…、T1(t)T2(t)T3(t)…T6(t)各入树组合的结构行为检验,提高模型的可靠性,构建了高校管理系统的系统动力学(SD)评价仿真模型.通过高校最重要人力资源教师发展规划实施调控函数的不同调控参数下分别进行全系统仿真,分别揭示十二五、十三五期间各年满足教育部评价指标的教师数、在校生数、校建面积、教学设备、专业、收支差的数据复杂定量变化结果.为典型高校未来发展提供了具普遍意义的决策依据,为基于评价指标建立仿真方程,为提高仿真模型可靠性提供了新方法. 相似文献

We present a new technique for proving logarithmic upper bounds for diameters of evolving random graph models, which is based on defining a coupling between random graphs and variants of random recursive trees. The advantage of the technique is three‐fold: it is quite simple and provides short proofs, it is applicable to a broad variety of models including those incorporating preferential attachment, and it provides bounds with small constants. We illustrate this by proving, for the first time, logarithmic upper bounds for the diameters of the following well known models: the forest fire model, the copying model, the PageRank‐based selection model, the Aiello‐Chung‐Lu models, the generalized linear preference model, directed scale‐free graphs, the Cooper‐Frieze model, and random unordered increasing k‐trees. Our results shed light on why the small‐world phenomenon is observed in so many real‐world graphs. © 2016 Wiley Periodicals, Inc. Random Struct. Alg., 50, 201–224, 2017 相似文献

在“新工科”建设的背景下,对于核心基础课绪论章节的内涵式教学设计势在必行。以“大学化学”课程为例,通过化学简史讲过去、诺贝尔化学奖展现在、化学学科分支谈内容、化学与生活激兴趣、中国化学家故事讲思政和课程要求讲考核等教学设计,深挖核心基础课的绪论章节的内涵。具有内涵的绪论课,不但可以激发学生学习化学兴趣,有助于培养学生化学思维解决问题的能力,而且可以将课程思政润物细无声切入,培养具有家国情怀和民族自豪感的航空航天领域人才。 相似文献
