网络教育中的电子学习观

网络教育中存在着三种不同的利益主体:教育决策者、教育者和学习者。与此相应,网络教育中也有三种电子学习观:教育决策者大力推广电子学习;教育者部分支持电子学习和学习者排斥电子学习。这是在不同的需要支配下产生的教育功能观、教育效益观和教育技术观所导致的。对此本文作出自己的阐述。     

电子学习的设计与评价——写给为教育信息化而努力的人们

当前,随着信息通信技术的发展,电子学习(E-learning)成为全球范围内关注的热点问题。我国的网络教育规模也不断扩大,招生剧增,这使大量学习者能有机会接受基于“名师、名校、名教材”的高等教育。此外,许多信息技术领域的企业也都开始致力于这一新兴的潜力巨大的电子学习市场。随着网络教育规模的扩大,其质量问题越来越引起了人们的关注。由于网络教育是一个新生事物,各个网络教育机构对于网络教育的整体框架和关键问题还缺乏完整而深入的认识。无论是网络教育机构,还是企业领域的网络培训,往往只是关注课程资源的开发和传输,而未能建立完…

MOOCS: digesting the facts

The techniques used in massive open online courses (MOOCs) are compared with supersizing in the fast food industry. Similarities include the profit motives, marketing techniques, criticisms, industry defences, and evolution of the two controversies. While fast food restaurants strategically increase the size of their meal courses and consumer base, MOOC providers increase the size of their student enrolments and the amounts of online course material they provide for the students to consume. In the two contexts, franchise owners and educational administrators deliver the supersized courses to their customers with apparent disregard for their widening negative effects. Educational institutions are encouraged to consider the ethics of these practices in order to prevent the unmonitored spread of junk education.

The Adoption of International Communications Networks and Electronic Mail into Foreign Language Education

This article reports a study of the possibilities of communications networks and electronic mail (e‐mail) in foreign language (FL) teaching. The research model combined FL education and information technologies (communications networks and e‐mail). The study was a multisite ethnographic case study, with elements of exploratory, collaborative, change‐oriented field‐work‐based development research. The Finnish participants included six classes (Form 1 or 2) in three senior secondary schools, with four teachers of English. The foreign participants came mainly from schools in Britain and the USA. Data gathering techniques included a number of various qualitative methods. Introducing a technological innovation into FL classrooms was quite successful. The teachers realized that communications networks would soon be an integrated part of FL teaching, though incorporating them in the FL curriculum called for extra work. There was some change in methods of work, taking the authenticity of e‐mails into account, though the linguistic features of the e‐mails were occasionally over‐emphasized. The lesson format was learner‐centred but somewhat teacher‐monitored. Learners’ autonomous, dyadic and small group work increased, while teachers partly became co‐learners with students.     

An Investigation of the Use of E‐Mail as a Supplemental Modality for Clinical Supervision

The authors investigated the use of student‐initiated e‐mail as a supplemental modality for supervision. Nineteen students e‐mailed their instructors weekly during their 15‐week practicum; these e‐mails were analyzed across 3 time periods using the categories of the discrimination model (J. M. Bernard, 1979, 1997) and an adaptation of W. Lanning's (1986) professional behavior category. Although patterns of e‐mails were similar across time, there was a significant decline in the number of e‐mails as the practicum progressed. Significance was found for message focus, with personalization messages and professional behavior/practicum class messages accounting for more than half of the messages across 3 time periods.     

后疫情时代混合式教学模式在高校思政课教学中的应用

高校思想政治理论课长久以来面临三个棘手问题,即“出勤率低”“听课率低”“抬头率低”,传统的线下教学容易出现“单向灌输”的弊端。由于疫情大规模出现的单一线上教学则易导致学习效率低、学习目的盲目等问题。后疫情时代,高校思想政治理论课教师进行新型的线上线下混合式教学模式的改革势在必行。线上线下混合式教学模式具有多维性、灵活性、多样性、实践性等优点,有助于提高学生学习兴趣,解决课堂三大难题,回归课堂立德树人的本质。线上线下混合式教学模式的改革创新应从以下方面着手:创建及完善与之对应的信息和教育平台;开发与之相配合的电子资料和工具;注重提高学生的独立研究能力及创造能力;推进考核形式的改革和创新;确保网络意识形态安全。     

浅谈计算机防火墙技术与网络安全

基于趋势和瑞星云安全方法的改进设计

现在,网络安全正面临着非常严峻的形势。云计算大量普及应用的前提是保证云安全。趋势科技和瑞星在这方面研究得比较成熟,已开发出相应的产品。趋势科技实施的是主动防御,能对来自网络的病毒进行有效的分析处理,但它不能对通过U盘、移动硬盘感染病毒的本地用户进行有效的防护。瑞星实施的是被动防御,能查杀来自本地机器的病毒,但不能对大部分的来自网络的威胁实施有效的分析处理。本文通过结合趋势科技、瑞星各自的长处,提出了一种结合主动和被动的、全新的、系统严密的病毒防范技术方案,并给出了以垃圾邮件为例的具体的防毒步骤。通过与前两家公司的防毒效果、内存和系统资源的占用方面的对比分析,证明这是一个可行、更加有效的严密的防毒技术方案。

Media Naturalness and Online Learning: Findings Supporting Both the Significant- and No-Significant-Difference Perspectives

Is the use of an online course delivery format, when compared with the more traditional face‐to‐face format, good or bad in the context of university education? Those who subscribe to the no‐significant‐difference perspective argue that online delivery is good, because it allows students with time and geographic distance constraints to obtain the education that they need, with no significant negative impact on the quality of the learning experience. Others argue that online delivery is bad, advocating a version of the competing significant‐difference perspective, because the electronic communication media used for online delivery are not rich or natural enough to enable effective learning. This study contrasted students perceptions and grades in two different sections of the same course: one delivered entirely online and the other delivered face to face. Data were collected and analyzed at two points in time, namely, at the middle and end of a long semester. The study found support for both the no‐significant‐ and significant‐difference perspectives. At the middle of the semester, students in the online condition perceived communication ambiguity as significantly higher, and also obtained significantly lower grades, than students in the face‐to‐face condition. At the end of the semester, no significant differences were found.
