虚拟实验和真实实验的比较研究 总被引：2，自引：0，他引：2
实验是促进科学技术发展的重要手段,也是教学中不可缺少的重要环节。多年来,传统的实验方法（即真实实验）在帮助学生学习基本理论、基本知识和基本技能及培养学生分析问题和解决问题的能力方面发挥了重要的作用。近年来,随着虚拟技术的飞速发展,虚拟实验作为一种新兴的实验技术得到了迅速发展。真实实验和虚拟实验共同走入教学中,都对教学起到了举足轻重的作用。为此,笔者感到有必要对虚拟实验和真实实验作一下比较分析,从而有利于我们恰如其分地运用这两种教学手段。 相似文献

A new class of post-secondary education has emerged in recent years—the virtual university—in which educational opportunities are delivered worldwide without regard to time constraints or location. Supporters of virtual and transnational learning environments abound as do those who question asynchronous on-line learning for its alleged impersonal nature. They note the limitations of its enabling technologies, and contend that such traditional instructional supports as access to physical libraries are shortchanged or non-existent. This article explores some of the issues surrounding library and information technology support for virtual learning environments through a focus on four models, each illustrated by a world-class example, that demonstrates good practice. The article concludes with observations on the mutual need that virtual and physical libraries have, one for the other. 相似文献

This article provides an overview of the programmes, the faculty, and the instructional model of International University. This institution delivers all its courses and degree programmes using multiple media. As IU has a “virtual campus”, Internet e‐mail and course‐specific Web pages serve as the primary instructional tools for interaction between faculty members and students. All the content and media components are developed exclusively to provide an instructional model that requires faculty to contemplate their roles as teachers. The article further describes a new multi‐tiered faculty structure, the instructional design and delivery of content, the providing of student and faculty services in an on‐line environment, and the development of pedagogy to facilitate teaching and learning on‐line. 相似文献

This article studies the differences in student learning outcomes associated with changes in the format of online learning resources. We compare completion rates and degrees of student achievement across several economic education learning modules produced by the Federal Reserve Bank of St. Louis. Initially designed as a long-form online learning module focused on unemployment, the virtual lecture “The Story of Unemployment” was later chunked into four separate short-form learning modules. We find across-the-board evidence of increased completion rates among registered students and statistically significant increases in average differences between pre-test and post-test scores. We also study how the increases in scores are distributed across students by comparing pre-test grade quartiles. Finally, we document that chunking online instructional materials increases retained learning and consistently boosts information absorption at the item level. 相似文献

Universities worldwide offer web‐based courses distributed by virtual learning environments (VLEs). A common theoretical framework for implementing VLEs is the pedagogical perspective of instructional design. In this paper, three perspectives of implementation from information systems implementation research and organization theory are presented: implementation as technology acceptance, implementation as diffusion of innovations and implementation as a learning process. These perspectives focus on the VLE as an information system within an organization, the university. The models reviewed offer an important complementary perspective to the pedagogical view of instructional design. The three implementation perspectives are compared and a conclusion is made concerning their implications of successful use and implementation of VLEs. 相似文献

Interest in the instructional application of virtual worlds, such as Second Life (SL), has grown substantially. However, little information is available about effective instructional activities using virtual worlds. This case study illustrates lessons learned from a pilot integrating SL into a two-semester English course at a large southwestern US university. A building activity was implemented in the first semester, and based on qualitative and quantitative formative evaluation results and additional planning, the instructional activity for the second semester was modified. These changes substantially enhanced students' learning experiences. Eight general and five discussion/debate-specific best practices discussed for implementing SL in college-level courses include capitalising on social interactions and establishing a clear connection of activities with learning objectives. This study demonstrates the importance of combining careful instructional design with ongoing assessment when implementing emerging technologies. It also indicates that course learning goals and students' needs should be considered first and foremost when adopting new technologies for instruction. 相似文献

The notion of multiculturalism is vital in our global society. The emergence of efficient and effective distance learning technologies has permitted the integration of innovative techniques in the delivery of multicultural content to individuals who need flexible and convenient education and training opportunities. Strategies form the instructional foundation that promotes engagement of learners. Integral to these strategies are those that relate to personal belief systems and extension of those belief systems to behaviors. This article will add new ways of teaching and learning in the areas of diversity and multiculturalism by offering a model for building highly supportive, engaging online environments, where instructors, trainers, and instructional designers use multiple strategies to build virtual environments that foster a sense of dignity, respect, and understanding: all critical elements in a global environment. 相似文献

This article focuses on the design of competency-based performance assessment in e-learning. Though effort has been invested in designing powerful e-learning environments, relatively little attention has been paid to the design of valid and reliable assessments in such environments, leaving many questions to educational developers and teachers. As a solution to this problem, a systematic approach to designing performance assessments in e-learning contexts is presented, partly based on the 4C/ID model. This model enables the construction of realistic whole tasks instead of advocating education that is restricted to more isolated skills. A new assessment procedure also implies an alternative view of instructional design, learning and assessment. The requirements for the learning environment are addressed. Examples from a virtual seminar are presented to illustrate the design approach. The article concludes with the identification of possible pitfalls related to the approach and gives directions for future research. 相似文献

Social factors play an important role in determining whether instructional communication in computer-supported settings will
be successful. Social presence is a social factor, specifically addressing the feeling of being present with another person in a virtual environment. This
article describes possibilities to influence the feeling of social presence in synchronous learning scenarios using desktop
collaborative virtual environments (CVEs). Desktop CVEs are technically simple compared with immersive CVEs and can be adapted
according to the needs of the users. In this article, possible adaptations are described using the example of the desktop
CVE virtual team room. In CVEs, users are represented as avatars. Avatars may or may not convey nonverbal signals. The focus
of the article is on whether the actual use of nonverbal signals can affect the sense of social presence and thus help to
establish and maintain the learner's motivation and provide support for structuring social interaction in learning situations.
The paper provides a review of exploratory studies and experiments as well as a report on the author's own studies. Future
research questions concerning learning in CVEs are discussed. 相似文献
