“三环互动”教学模式是黑龙江电大在开放教育试点项目中总结出的一种基于网络环境下的教学模式。它以“学生自主学习为主,教师辅导为辅”的教学指导思想,将学生学习的过程分为“自学、导学、考核”三个教学环节。本文根据教学实践,通过网上互动和资源建设研究两方面分析“三环互动”教学模式在现代远程教育中的应用与所起到的作用。 相似文献

传统的英语课堂教学模式比较单一,课堂基本是老师讲解为主,学生活动为辅,使学生对英语学习越来越缺乏主动性;根据高职英语教学指导思想,对高职学生英语培养原则是:实用为主,够用为度,以培养应用型人才为主。因此,根据网络教学环境,提出适应高职英语教学的多种教学模式。 相似文献

物理是一门以实验和观察为主的学科,从生活中引出材料,通过实验探究出其中的物理规律和原理,是学习物理学的重要途径。《新课标》的实施无疑给教师的教学和学生的学习指出新的思路,给学生的学习带来浓厚的兴趣,也提高教师教学的积极性。学生通过实验探究,学到了科学知识,掌握了探究科学知识的方法,同时也增强了创新能力和实践能力。那么,如何培养学生的实验探究能力呢?一、创设科学探究的学习环境,构建新型的师生互动平台以教材为主,实验为辅的旧教学模式在农村中学中根深蒂固,从过去的以讲授法为主的教学思想——“传道、授业、解惑。”到… 相似文献

目的:改革以往本科生皮肤性病学实验课教学中单纯播放录像的教学模式,探讨微信联合PBL、CBL教学模式在皮肤性病学实验课教学中的应用效果。方法:选择典型的临床病例,上课前教师用微信将要讨论的典型病例照片发到学生微信群,将每个班学生分为2组,每组约15人,以组为单位进行分组讨论并写出实验报告,上课时教师和学生一起讨论、互动,给出正确答案,课后教研室组织教师评阅学生上交的实验报告,教师给出的实验成绩作为整组学生的实验成绩。结果:提高了学生实验课学习的满意度,提高了学生的实验课学习成绩,大大缩短了教师阅卷时间,减轻了教师负担。结论:微信联合PBL、CBL教学模式可作为一种皮肤性病学实验课教学模式进行推广。 相似文献

主题教学模式以建构理论为主,教学注重人文关怀、师生合作为辅,理念是“以学生为主体、教师为主导”,教师将拓展和深化的任务交给学生,在真正意义上提高学生的自主能力.该教学模式相对于传统教学而言,会通过设计主题、创设教学情景来形成师生之间、学生之间的“互动”,所以,主题教学如果想要保障预期教学效果的实现,就更需要控制课堂教学. 相似文献

This study examined how students who had no prior experience with videoconferencing would react to the use of videoconferencing as an instructional medium. Students enrolled in seven different courses completed a questionnaire at the beginning of the semester and again at the end of the semester. Students at the origination and remote sites did not differ in their reactions toward videoconferencing but there was a significant difference for gender. Women reacted less favorably to videoconferencing. Compared to the beginning of the semester, students reported significantly less positive attitudes toward taking a course through videoconferencing at the end of the semester. There were no significant differences in students' attitudes toward videoconferencing across courses at the beginning of the semester but there were significant differences across the courses at the end of the semester. The results suggest the need for better preparation for both students and instructors. 相似文献

A computer-mediated group is a complex entity whose members exchange many types of information via multiple means of communication in pursuit of goals specific to their environment. Over time, they coordinate technical features of media with locally enacted use to achieve a viable working arrangement. To explore this complex interaction, a case study is presented of the social networks of interactions and media use among members of a class of computer-supported distance learners. Results show how group structures associated with project teams dominated who communicated with whom, about what, and via which media over the term, and how media came to occupy their own communication niches: Webboard for diffuse class-wide communication; Internet Relay Chat more to named others but still for general communication across the class; and e-mail primarily for intrateam communication. Face-to-face interaction, occurring only during a short on-campus session, appears to have had a catalytic effect on social and emotional exchanges. Results suggest the need to structure exchanges to balance class-wide sharing of ideas with subgroup interactions that facilitate project completion, and to provide media that support these two modes of interaction. 相似文献

Electronic data interchange (EDI) provides means for interorganizational communication, creates network externalities, requires an advanced information technology (IT) infrastructure, and relies on standards. In the diffusion of such innovations, institutional involvement is imperative. Such institutions contain governmental agencies, national and global standardization organizations, local government, and nonprofit private organizations like industry associations. The last type of organizations we call intermediating institutions. They intermediate or coordinate ("inscribe") the activities of a group of would-be adopters. Unfortunately, little is known of how these organizations shape the EDI diffusion trajectory. In this article we examine one specific type of intermediating organizations?industry associations?and how they advanced the EDI diffusion process in the grocery sectors of Hong Kong, Denmark and Finland. We identify six institutional measures, placed into a matrix formed by the mode of involvement (influence vs. regulation) and the type of diffusion force (supply push vs. demand pull), that can be mobilized to further the EDI diffusion. Industry associations were found to be active users of all these measures to varying degrees. Their role was critical especially in knowledge building, knowledge deployment, and standard setting. Furthermore, institutional involvement varied due to policy and cultural contingencies and power dependencies. 相似文献

The increasing prospects of digital piracy has prompted the perceived need by electronic publishers to adopt technical systems of protection, and governments to reform their copyright laws. This article is a preliminary study of the management of intellectual property by electronic publishers, defined as those involved in the production of online databases, and CD-ROMs. It focuses on three main issues: (1) how electronic publishers view the increasing threat of piracy; (2) the methods of protection employed to protect intellectual property in digital format; and (3) the importance of technological protection of intellectual property in electronic publications. The analysis is based on a sample of 23 UK electronic publishers. The interviews revealed an interesting assortment of protection methods and did not show that technological protection was a preferred way. Instead, the means of protection, in addition to copyright law, comprised niche markets, pricing, trust, bad publicity, and nontechnical and technical means. 相似文献

Long-standing conflict between domain name registrants and trademark holders prompted the Internet Corporation for Assigned Names and Numbers (ICANN) to create a global, mandatory arbitration procedure known as the Uniform Dispute Resolution Policy (UDRP). The UDRP has been used in 2166 cases involving 3938 domain names as of 1 November 2000. The policy gives the initiator of a complaint, generally a trademark holder, the right to choose which ICANN-accredited dispute resolution service provider (RSP) will handle the case. During the preparation of the UDRP,some feared that complainant selection would lead to "forum shopping" that might bias the results. This article performs a statistical assessment of the forum-shopping thesis and finds support for it. There are statistically significant differences in the various RSPs' propensity to take away names from defendants; there are also major differences in the number of cases brought to each RSP. RSPs who take away names have the larger share of cases. The study examines other variables that might explain differences in market share, such as price, the plaintiff's nationality, or the time taken to decide a case. It finds that nationality and time also are correlated with market share. The study concludes that shopping for a favorable outcome is an important factor in the UDRP. 相似文献

<正>In Xishuangbanna,one of China’s most biodiverse regions,landscape has changed dramatically during the past three decades due to the conversion of tropical rainforest to rubber plantations.In steep areas,terraces are often constructed before planting rubber trees,which causes two important changes in the soil:the destabilization of soil in the bench terraces and the increased vulnerability of unvegetated riser faces to erosion.Few studies have documented the nature and intensity of erosion on bench terraces.Prof.LIU Wenjie and his colleagues from the Xishuangbanna Tropical Botanical Garden(XTBG)conducted a study in Menglun County(21°5′39″N,101°15′55″E),Xishuangbanna to evaluate the influence 相似文献
