困境与破解:小学教师职业幸福感探析--以杭州市C小学为例

就杭州市C小学教师"职业幸福感"的调查显示,该小学教师存在职业倦怠、成长诉求、职业发展等方面的问题,教师缺乏幸福感。从教师管理的角度来看,其原因主要在于:"关爱缺位"减退了教师幸福指数,"诉求过场"阻碍了教师投入动力,"评价单向"局限了教师快乐发展。针对存在的问题,C小学实施了三个策略:一是学校推动,自上而下突进,营造幸福场域;二是教师行动,自下而上突击,贯通幸福维度;三是整体联动,上下结合突围,彰显幸福效度。三个策略的实施,有效推动了教师群体在学习方式、教科研能力、教育方法等方面的提升,激发了教师的内在驱动力和职业幸福感。

我党老一辈革命家从爱国主义者成长为共产主义者的道路

20世纪20年代，我党老一辈无产阶级革命家实现了从爱国主义者到共产主义者的转变。其道路是：关心国事，研究国情是转变的必要前提；追求真理，追求光明是转变的动力。勤奋学习，刻苦钻研为转变锻造了知识基础；注重修养，锐意进取为转变锻造了思想品质基础。     

“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.     

安徽省与周边省份资本分布情况比较研究

将安徽、山东、江苏、江西四省并列,对90年代以来影响各省资本分布的各个因素:区域经济增长差异、财政转移支付差异、信贷投放差异、外商直接投资利用差异进行了深入分析并对四者所反映出来的情况与问题做了系统研究,从而发现从中央财政支付转移的角度看,山东、江苏二省每年都有相当数额的财政收入上缴中央政府,而安徽、江西二省2000年以来每年都接受大量的中央政府财政补贴,并有逐年增大的趋势.从银行及其资本渠道来看,四省均出现资本外流现象.     

Mathematical Modeling in the Primary School: Children's Construction of a Consumer Guide

This paper examines 6th grade children's local conceptual development and mathematization processes as they worked a comprehensive mathematical modeling problem (creating a consumer guide for deciding the best snack chip) over several class periods. The children and their teachers were participating in a 3-year longitudinal teaching experiment in which sequences of mathematical modeling problems were implemented from the 5th grade (10 years of age) though to the 7th grade. In contrast to traditional problem solving, mathematical modeling requires children to generate and develop their own mathematical ideas and processes, and to form systems of relationships that are generalizable and reusable. Reported here is a detailed analysis of the iterative cycles of development of one group of children as they worked the problem, followed by a summary of the mathematization processes displayed by all groups. Children's critical reflections on their models are also reported. The results show how children can independently develop constructs and processes through meaningful problem solving. Children's development included creating systems for operationally defining constructs; selecting, categorizing, and ranking factors; quantifying quantitative and qualitative data; and transforming quantities.

CILT2000: Visualization and Modeling

CILT2000 helped VisMod evolve from a collection of local and distinct research and development efforts into a solid field of education. Previous intellectual efforts focused around a) modeling and simulation tools, b) visual explanation tools, c) visual data analysis tools, d) exploring student needs in the context of VisMod, and e) exploring instructional frameworks for VisMod. These focus areas have evolved in two main trajectories, representing the evolution of the field, the generalization trend, which seeks to identify general principles and guidelines for designing learning environments, and the equitable application trend, seeking to use knowledge gained in the field to leverage education in general.
