语言虚拟仿真实验教学的探索、实践与评述——以“大学英语虚拟仿真实验”公共选修课为例

解构语言虚拟仿真实验教学的运行机理、体系结构、实验步骤,对高校开展语言虚拟仿真实验有重要的参考价值。基于此,文章首先通过将心流体验中介效应引入语言虚拟仿真实验教学,构建了语言虚拟仿真心流体验概念模型,提出了语言虚拟仿真实验教学体系,并对教学环境搭建、实验步骤进行了系统阐述。随后,文章以北京邮电大学的"大学英语虚拟仿真实验"公共选修课为例,进行了语言虚拟仿真实验的教学实践,并对语言虚拟仿真实验与传统语言实验的效果进行了对比。最后,文章从优势和问题两个角度,对语言虚拟仿真实验教学进行了评述,以期为高校开展语言虚拟仿真实验的设计和实施提供参考。

MOOC学习者参与行为实证研究——以“中国大学MOOC”外语课程为例

研究外语MOOC(Massive Open Online Course,大规模在线开放课程)课程影响力的影响因素及讨论区帖子关注度的影响因素,为外语类MOOC课程设计、授课、讨论交互、平台改进提供具有针对性的策略和建议,以期更好地扩大外语类MOOC课程的影响力。研究数据采集自国内知名MOOC平台的外语课程和学习者数据,利用回归分析解构MOOC课程参与人数和讨论区帖子关注度的影响因素,并通过文本挖掘获取学习者的关注热点。研究发现:教师粉丝数、授课经验和讨论区活跃度显著影响课程参与,专门用途、跨文化交际课程帖子关注度更高,学习疑问和课程设计的帖子关注度更高,教学者和平台开发者应在课程设计、授课形式、交互方式和平台易用设计等方面进行改善。

Telecommunications reforms in Pakistan-lessons and suggestions for China

The worldwide strategy for the development of telecommunications has been the opening of the telecom sector to competition and private investment.This paper focuses on telecommunications reforms and its outcomes in Pakistan and discusses some lessons and suggestions for China who is still in the process of formulating telecom law.After liberalization and deregulation,telecom industry in Pakistan is tremendously growing and is in a transition phase from the monopoly to the competition.Government policies and independent regulator is playing critical role in this growth.This paper suggests that speed up formulation of Telecom Law,establishment of independent regulatory and antitrust agencies are need of time for the China telecom industry.Further,China will have to give special attention to accommodate convergence in its coming model of telecommunications reforms.
