对大学英语多媒体网络化教学的几点思考

随着我国大学英语教学改革的深入,各高校正在逐步推行利用多媒体、网络技术辅助学习的新的教学模式.目前许多高校的大学英语教师都对其寄寓厚望,认为这种教学模式是解决当前大学英语教学中存在的很多问题的有效途径.然而,多媒体网络化教学对硬件、软件、教师和学习者要求都很高.鉴于此,文章通过分析大学课程采用的这一教学模式所存在的问题,提出自己的几点建议.     

大学英语教学新模式下的自主学习研究

自《大学英语课程教学要求(试行)》颁布以来,国内众多高校利用现代教育技术,在构建学生自主学习模式等方面进行了一系列的改革探索。在新的时代要求下,自主学习的培养变得越来越重要,成为大学生学好英语的一项必要技能。有限的课时、充足的课余时间以及丰富的学习资源为大学生自主学习英语提出了要求也提供了条件。大学英语教师应当长期坚持不懈地努力,培养大学生的自主学习能力。

Death of Rationality: The Social Networks’ Factor in Policy Response to Ebola

The sociopolitical role of social networks in public decision-making is far from fully understood. Their fast-pace and elusive nature makes the situation fluid and therefore susceptible to rushed theorization. The emerging dominant view is that social networks increase mass political polarization. A new view proposes that social networks increase harmony and tolerance. By examining the role of social networks in the policy response to Ebola in the United States, this paper suggests that social networks play a dual role: increasing polarization around politically divisive issues and promoting tolerance regarding less contentious issues. The paper also expanded the definition of social networks to include online discussions forums. Using the public choice theory and its rational model as a frame of reference, the study focused on six online forums during the peak of Ebola scare, October 2014 through January 2015.     

Cuba: heading for a new development and political model – an introduction

Cuba, this iconic revolutionary island which has brought so much hope to the Third World and, at one point, worry for a nuclear World War III, is going through a process of change never seen since Fidel Castro led his revolutionary forces to triumph around New Year’s of 1959. Yet, 10 years into the change process, led by the younger Castro Raúl (now 85), nobody can really forecast where the country will end up in socio-economic and political terms. In this TWQ subsection, two economists and three political scientists – two Cubans and three European Cuba watchers – analyse the reforms and their possible outcome.     

Participation for What? A Policy-motivated Approach to Political Activism

Normatively and intuitively, we conceive of political participation as an integral component of democratic policymaking. However, research on participation generally does not include policy considerations as part of individuals’ decisions to engage in activism. I offer an opportunity model of participation that begins to study how policy goals shape individual participation and how aggregate participation shapes policymaking. The central argument is that individuals’ policy goals allow them to recognize those moments when it is most efficient and/or effective to take action. Examining black participation from 1980 to 1994, I show that black Americans are more likely to participate when they face external threats, are embedded in social networks, and have greater access to policymakers. Most importantly, the recognition of these opportunities varies according to individuals’ resources. This research moves beyond the discussion of who participates to address the equally fundamental question: participation for what?
