网络远程教学交互研究的现状及问题分析 总被引：7，自引：0，他引：7
目前,基于网络的远程教学过程中影响教学效果的问题主要体现在两个方面:一是远程教学中协作学习或活动的开展与实施;二是网络远程教学中信息反馈的顺利进行,即网络教学交互问题的研究和探讨。尤其是后者已经成为网络远程教学发展的瓶颈,远程教学交互活动的设计与实现不仅是推动当前远程教育发展的主要动力,而且也是维系远程教育发展的生命线。为此,非常有必要从研究远程教学过程的交互性出发,探讨一条既符合现代教育理论和教学规律,又符合现代网络远程教学的特点,能大幅度提高远程教学质量和教学效率的道路。一、网络远程教学交互研究的现状… 相似文献

基于HFC的双向视音频远程教学系统的设计 总被引：1，自引：0，他引：1
刘兴红 《中国远程教育(综合版)》2006,(6):71-72
双向视音频远程教学系统是传统课堂面授与现代电视网络及多媒体通讯技术完美结合的现代远程教学新形式。基于HFC的双向视音频远程教学系统打破了基于计算机多媒体技术和宽带网络通信技术教学系统的常规思路,是在HFC网络结构优势的基础上设计的双向视音频远程教学系统。本文采用框图直观地描述了基于HFC的双向视音频远程教学系统的结构,并阐述了系统的主要技术性能及特点。 相似文献

现代远程教学范式是教育科学共同体在远程教学领域内,所共有的学术信念、价值规范、基本理论模型、教育技术及教学行为方式的总称。预成性远程教学范式具有预成性和去生活性的特征,在其统摄下,远程教学陷入了成效不佳的困境。而生成性远程教学范式是对预成性远程教学范式的建设性的超越,它具有生成性、情境性、生活性的特征。远程教学范式从＂预成性＂向＂生成性＂的转变,对于摆脱教学困境,扩展课程与教学的生成性空间,促进远程学生的创造性和个性的发展,具有重要的实践意义。 相似文献

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help? 相似文献

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love. 相似文献

People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject. 相似文献

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities. 相似文献

Today, Sunday morning, I sit thinking and typing at my computer. My thoughts are in my homeland, India and my body is in China. The body is here and mind there for a good reason. Mr. Hu is president and I am resident and both are in each other's countries (what a difference the absence of one small letter makes!). Mr. Hu will return in a few days and I will stay on longer. 相似文献
