Enacting Informal Science Learning: Exploring the Battle for Informal Learning

Informal Science Learning (ISL) is a policy narrative of interest in the United Kingdom and abroad. This paper explores how a group of English secondary school science teachers, enacted ISL science clubs through employing the Periodic Table of Videos. It examines how these teachers ‘battled’ to enact ISL policy in performative conditions at the micro-scale, and how this battle reflected macro-scale epistemological and political considerations. Data from the study suggests that for some, ISL was low stakes as it was seen to have negligible impact upon performance data. As a result, there was some resistance towards enacting ISL and conflict between the formal and informal curriculum processes. Nonetheless, analysis indicates that the informants highly valued ISL despite the requirement for them to justify it over more formal and ‘effective’ approaches to learning science.

Skill mismatch and work–life conflict: the mediating role of job satisfaction

Previous research examining skill mismatch in the labour market has ignored potential implications for workers outside of the work environment. We argue that the psychological strain that the discrepancy between worker’s skills and job requirements wields on workers spills over into the non-work sphere, increasing work–life conflict. This study explores the consequence of skill mismatch for work–family life and various dimensions of job satisfaction. Using the 2011 British Workplace Employment Relations Survey (WERS), we find that both over- and underskilled workers reported lower satisfaction with achievement and autonomy, opportunity for development, and pay and security. Results also suggest that not only does skill mismatch have a negative influence on work–life conflict but that this association is completely mediated through job satisfaction. Given this better understanding of the complex ways that skill mismatch in employment shapes non-work life, implications for employees and firms are discussed.     

泰国学生汉语差比句习得的特点及偏误分析

文章对比了泰国学生中介语语料与汉语母语者语料中差比句的使用情况,分析了泰国学生差比句习得的特点和偏误类型。研究发现,泰国学生中介语语料与汉语母语者语料中各句式的使用频次不完全一致,使用频次与正确使用频率也不完全一致;泰国学生汉语差比句偏误率较高,偏误类型复杂多样,其主要原因在于汉泰语＂比/■＂字句在形式和功能意义上错综复杂的对应关系和对应＂空缺＂。文章最后提出了针对泰国学生汉语差比句的教学策略,确定了有＂泰国特色＂的差比句教学难度等级序列。     

基于角色理论视角的高校师生关系失调的研究

高校师生角色关系是一种围绕教育教学过程而形成的特殊人际关系,是教师和学生角色互动的结果。基于角色理论的视角,探讨目前高校师生角色关系失调的主要表现为：师生角色间冲突、师生角色不清和师生角色失败;究其原因主要是：角色规范的表面化使得师生角色行为缺乏指导和制约、角色期望的模糊不清或者冲突使得师生角色行为无所适从;并在此基础上提出从角色环境入手明确师生角色规范和期望、从角色主体入手强化师生对角色规范和期望的认同两方面改善师生角色关系失调的建议。

族群冲突与国家控制:以清代台湾三大民变为例

清领台湾时期,台湾社会动乱不断,其中历时最久、波及最广的是所谓"三大民变"。在这三大民变中夹杂着复杂的族群关系,民变的起事者是漳州籍或泉州籍的福佬人,客家人则站在对立面,充当义民。对于民变中族群冲突的认识,不论是清廷或是民变领袖都经历了一个过程,他们都曾试图消弭不同族群之间的冲突,建立一个泛族群的联盟,但未达到预期的效果,"族群分类"的矛盾并未消失,又孕育着新的矛盾。

知识社会学：师生冲突的一种研究视角

知识社会学为师生冲突研究提供了一个新的认识视角：在教育场域中,师生关系是在知识的再生产和接受中建立起来的。师生交往过程实质上是师生间知识的社会建构过程,师生冲突往往表现为师生知识视界的碰撞,其背后充斥着知识与社会权力的矛盾和斗争。教师合理消解与应对教育场域中师生冲突的策略是：更新冲突观,改变参与知识方式,与学生展开知识对话,引导学生学会知识选择。
