课外补习已成为一种普遍的教育和社会现象,如何给补习"退热"成为国家和学者关注的焦点。在生态系统理论的框架内,以社会治理的视角归纳出课外补习发展的成因:一是在传统育儿思想影响下,家长出现课外补习行为偏差;二是课外补习的市场化特征,迎合了家长的"应试"需求;三是学校教育均衡发展,增强了家长对课外补习的依赖;四是政府治理权责模糊,成为课外补习发展的"政治资本"。我国课外补习治理的特征与问题是:以政府治理为主导形式,缺乏其他利益主体协同参与的理念;以设置准入门槛为主要措施,但政策退热的方向有失偏颇;注重监管职责划分,缺乏问责机制的构建;增强学校主流教育竞争力,缺乏学校教育与补习教育融合发展的路径。结合我国主要地区课外补习的治理成效与经验提出由以政策规范为主的"政府治理模式",向协同各方利益群体为基础的"社会治理模式"转变,形成涉及家长、学校、社区和行业协会共同参与课外补习治理的责任联盟和命运共同体,以更加有效地实现课外补习治理的目标。

作者： S?ren im Sande yadong Deng Sergey I.Bozhevolnyi Fei ding Centre for Nano Optics University of Southern Denmark

Optical metasurfaces, comprising subwavelength quasi-planar nanostructures, constitute a universal platform for manipulating the amplitude, phase, and polarization of light, thus paving a way for the next generation of highly integrated multifunctional optical devices. In this work, we introduce a reflective metasurface for the generation of a complete(angularly resolved) polarization set by randomly interleaving anisotropic plasmonic meta-atoms acting as nanoscale wave *** the proof-of-concept demonstration, we achieve multidirectional beam-steering into different polarization channels forming a complete set of polarization states, which can also be dynamically altered by switching the spin of incident light. The developed design concept represents a significant advancement in achieving flat polarization optics with advanced functionalities.

我国课外补习机构的发展分为私人化和市场化两个阶段,与之相应的治理进展分为侦查、准备和主攻阶段。在明确课外补习机构价值的基础上,从规范的治理观出发,结合课外补习机构涉及的各利益主体的诉求,归纳我国课外补习机构的社会经济和教育价值以及治理阻力。各级政府应全面认识课外补习机构治理的持续性,有序推进治理措施,树立以课外补习机构价值为基础,以规范为导向的治理观;建立各利益主体间长效沟通机制,协同多部门联动治理、明确课外补习机构治理主体;建立负面清单治理模式,逐步实现课外补习机构治理目的。

使用中国教育追踪调查2014年数据(CEPS2014),运用多层线性回归和结构方程模型,分析了家庭教育与学生学习成绩的关系,探讨家庭教育环境对社会阶层流动的影响。研究发现,家庭教育硬环境和软环境越好学生的学习成绩越好;在家庭教育硬环境中,家庭基础设施越完善学生的学习成绩就越高;在家庭教育软环境方面,家庭中父母与学生沟通的次数越多学生的学习成绩就越好;父母在家中越注重维护和建立和谐的家庭关系,学生的学习成绩就越好。并从政府积极引导和宣传家庭教育,增强家庭教育在各家庭中的重视度等提出政策建议。
