This research explores the extent to which virtual worlds can serve as online collaborative learning environments for students by increasing social presence and engagement. 3D environments enable learning, which simulates face-to-face encounters while retaining the advantages of online learning. Students in Education departments created avatars that represented them at collaborative meetings and activities. The study examines students’ choice of Avatar appearance in relation to their own appearance and their prevailing social and cultural norms. It compares the appearance of avatars chosen by students from different countries and cultures through analysis of observations, questionnaires, and interviews. Does the user’s appearance affect his/her avatar’s appearance? Does the user’s culture affect his/her choice of avatar? Do 3D environments blur multicultural differences? Do similarities between students and their avatars contribute to their learning experience, and if so, in what way? Results indicate that although virtual 3D environments provide freedom, external contexts create powerful boundaries and expectations, leading many participants to seek a socially acceptable online appearance influenced by their cultural norms, as well as by online group identity. This study extends the dual-congruity perspectives of the Avatar Choice Model to a conceptual framework based on a quad-congruity perspective, including the importance of the online group and adding the constraining effect of offline culture and norms on virtual representations.
这项研究探讨了虚拟世界通过增加社交存在和参与,可以在多大程度上为学生提供在线协作学习环境。3D环境使学习成为可能,它模拟面对面的接触,同时保留了在线学习的优势。教育部门的学生创建了代表他们参加合作会议和活动的虚拟形象。这项研究考察了学生们对阿凡达外表的选择与他们自己的外表以及他们的主流社会和文化规范之间的关系。它通过观察分析、问卷调查和访谈,比较了来自不同国家和文化的学生选择的虚拟形象的外观。用户的外观是否会影响他/她的角色外观?用户的文化是否会影响他/她对头像的选择?3D环境是否模糊了多元文化差异?学生和他们的虚拟形象之间的相似之处是否有助于他们的学习体验,如果有的话,以何种方式?结果表明,尽管虚拟3D环境提供了自由,但外部环境创造了强大的边界和期望,导致许多参与者在其文化规范和在线群体身份的影响下寻求社会可接受的在线外观。本研究将虚拟化身选择模型的双重一致性视角扩展到基于四一致性视角的概念框架,包括线上群体的重要性,并增加了线下文化和规范对虚拟表征的约束作用。

Modeling the Organizational Aspects of Learning Objects in Semantic Web Approaches to Information Systems 信息系统语义网方法中学习对象的组织方面建模
Pub Date : 1900-01-01 DOI: 10.28945/424

The concept of learning object has become a central notion of the majority of current approaches to e-learning that focus on reusability and automation. Learning object metadata can be considered a driver for mediated resource location, thus fostering the development of digital repositories and intermediaries. Such entities are aimed to collect, store and expose rich learning object descriptions. This has lead to approaches for Semantic Web applications to e-learning that explicitly model learning objects as instances inside formal ontologies, thus representing metadata as logics-based sentences, with such sentences describing digital artifacts in terms of shared conceptualizations of diverse domains. Nonetheless, existing models do not explicitly consider the aspect of “value” inherent to learning processes and artifacts as components inside the context of organizational Information Systems. The Information Systems view regarding learning objects requires a consideration of the learning behavior of the organization as a whole, in which learning objects become critical resources linked to strategic or contingent organizational needs. This paper examines the role of learning objects as elements inside Information Systems, and provides a semantic definition for them that integrate the various aspects of learning processes in the organizational context. In addition, the main elements of a proposed formal ontology of learning objects inside organizational Information Systems are discussed by means of scenarios.
学习对象的概念已经成为当前大多数关注可重用性和自动化的电子学习方法的中心概念。可以将学习对象元数据视为中介资源位置的驱动程序,从而促进数字存储库和中介的发展。这些实体旨在收集、存储和公开丰富的学习对象描述。这导致了用于电子学习的语义Web应用程序的方法,这些方法显式地将学习对象建模为形式化本体中的实例,从而将元数据表示为基于逻辑的句子,这些句子根据不同领域的共享概念化来描述数字工件。尽管如此,现有的模型并没有明确地考虑到作为组织信息系统上下文中的组件的学习过程和工件所固有的“价值”方面。关于学习对象的信息系统观点要求将组织的学习行为作为一个整体加以考虑,其中学习对象成为与战略或偶然组织需求联系在一起的关键资源。本文考察了作为信息系统内部元素的学习对象的角色,并为它们提供了一个语义定义,该定义集成了组织环境中学习过程的各个方面。此外,本文还通过场景讨论了组织信息系统中学习对象的形式化本体的主要元素。

The purpose of the following study was to examine the impact of web-based learning tools (WBLTs) in science classrooms (grades 7 to 10) from the perspective of both teachers and students. Survey, qualitative, and student performance data were collected from a sample of 11 teachers and 371 students. Teachers were very positive about the learning benefits, design, and engagement value of WBLTs. Students were more critical, but still positive about these same features. Qualitative data suggested that students appreciated visual scaffolding, ease of use, engagement, and using technology. Student performance based on five knowledge categories (remembering, understanding, applying, analyzing, and evaluating) increased significantly when WBLTs were used. Finally, middle and secondary school students had similar attitudes toward WBLTs, but older students showed higher learning performance gains.

Learning about Online Learning Processes and Students' Motivation through Web Usage Mining 通过网络使用挖掘了解在线学习过程和学生动机
Pub Date : 1900-01-01 DOI: 10.28945/73
A. Hershkovitz, Rafi Nachmias
This study illustrates the potential of applying Web usage mining - the analysis of Web log files in educational research. It consists of two sub-studies and focuses on two types of analysis, both related to the whole learning process: investigating one learner's activity in order to learn about her or his learning process, and examining the activity of a large group of learners, in order to develop a log-based motivation measure. Subjects were 674 adults who used an online learning unit as part of their preparations for the Psychometric Academic Entrance Exam and whose log files were drawn. The first sub-study aimed to illustrate the knowledge about the online learner that can be extracted from log files, and this resulted in a list of computable, non computable, and higher-level learning variables. In the second sub-study, a log-based motivation measuring tool was developed on the basis of a theoretical framework, a mechanism for computing relevant learning variables, and a clustering of these variables into three groups (associated with the theoretical framework). A discussion of the results, in the context of educational Web mining, is provided.

Assessing the Efficacy and Effectiveness of an E-Portfolio Used for Summative Assessment 评估用于总结性评估的电子档案的有效性和有效性
Pub Date : 1900-01-01 DOI: 10.28945/1164

Introduction An e-portfolio is an organized compilation that demonstrates knowledge, skills, values, and/or achievements and that includes reflections or exegesis which articulate the relevance, credibility, and meaning of the artifacts presented (Cooper & Love, 2007). They are customizable to represent the uniqueness of an individual student, requiring reflection that encourages deep learning (Barrett, 2004). Further, e-portfolios can stimulate a dialogue about learning as instructors and peers provide feedback on the portfolios engendering further action and reflection on the part of the learner. An e-portfolio system is a repository management system used in the creation, storage, and assessment of e-portfolios. Under the name of artifacts, they are capable of including academic records, essays, project reports, assignments, audio and video files, assessments, and personal and professional development related contents linked to learning goals and reflections (Wang, 2009) . E-portfolio systems can be open source (e.g., Open Source Portfolio and Moodle's Exabis Portfolio Block), custom created by an academic institution (Purdue University's electronic portfolio system built using Microsoft's SQL and University of Singapore's Student Electronic Learning Folio developed using ASP.net), developed by an institution using open standards (e.g., Iowa's State University's eDoc), or commercially developed (e.g., eFolio, TaskStream). According to Wang (2009) among different e-portfolio systems there are significant variations in user interface design; however, regardless of platform, the functionalities of competitive e-portfolio systems are similar with all including capabilities for the uploading of artifacts, customization, commenting on and assessing student work, communicating and sharing, reflection, drawing linkages to goals, showcase generating, and varying forms of administrative reporting. Further, Wang (2009) explained that most available systems are subject independent and therefore useful across the academic spectrum. The University of Maryland Eastern Shore (UMES), a Historically Black University, has implemented an electronic portfolio project within the Department of Business, Management, and Accounting (Department) that is used for both summative and formative assessment as well as to encourage students to engage in deep learning and self reflection. The project was initially implemented with senior standing students and was gradually embedded throughout the curriculum starting with incoming freshmen. As a multi-year project, the goal is to help both students and faculty evaluate students' academic and professional development longitudinally (Buzzetto-More, 2010) . The project is designed to have several benefits: 1) Allowing both faculty and students to evaluate student growth and progression towards learning goals. 2) Encouraging students to reflect on their own growth and development. 3) Serving as a tool to guide the student in their
电子档案是一个有组织的汇编,展示了知识、技能、价值观和/或成就,包括反思或注释,阐明了所呈现的工件的相关性、可信度和意义(Cooper & Love, 2007)。他们是可定制的,以代表个别学生的独特性,需要反思,鼓励深度学习(巴雷特,2004)。此外,电子档案可以激发关于学习的对话,因为教师和同伴会对档案提供反馈,从而促使学习者采取进一步的行动和反思。电子投资组合系统是用于创建、存储和评估电子投资组合的存储库管理系统。在工件的名义下,它们能够包括学术记录、论文、项目报告、作业、音频和视频文件、评估以及与学习目标和反思相关的个人和专业发展相关的内容(Wang, 2009)。电子投资组合系统可以是开源的(例如,开源投资组合和Moodle的Exabis投资组合块),由学术机构定制创建(普渡大学的电子投资组合系统使用微软的SQL构建,新加坡大学的学生电子学习Folio使用ASP.net开发),由使用开放标准的机构开发(例如,爱荷华州立大学的eDoc),或商业开发(例如,eFolio, TaskStream)。Wang(2009)认为,在不同的电子投资组合系统中,用户界面设计存在显著差异;然而,不管平台是什么,竞争性电子投资组合系统的功能都是相似的,包括上传工件、定制、评论和评估学生作业、交流和共享、反思、绘制与目标的联系、展示生成以及各种形式的管理报告。此外,Wang(2009)解释说,大多数可用的系统是独立于学科的,因此在整个学术领域都很有用。马里兰大学东岸分校(University of Maryland Eastern Shore)是一所历史悠久的黑人大学,它在商业、管理和会计系(Department of Business, Management and Accounting)内实施了一个电子作品集项目,用于总结性和形成性评估,并鼓励学生进行深度学习和自我反思。该项目最初是在高年级学生中实施的,并逐渐融入到从新生开始的课程中。作为一个多年的项目,目标是帮助学生和教师纵向评估学生的学术和专业发展(Buzzetto-More, 2010)。这个项目有几个好处:1)允许教师和学生评估学生的成长和学习目标的进展。2)鼓励学生反思自身的成长与发展。3)作为指导学生学术和职业规划的工具。4)帮助学生了解课程如何与现实世界的实践相联系。5)帮助学生看到课程学习的相互关系,以及课程学习如何转化为自己朝着学习目标的发展。6)提供灵活的评估方法,让学生有更多的自主权和更多的成功机会。7)提供以学生为中心的方法来衡量学生对学习目标的掌握程度,鼓励深度学习。8)通过为主要是第一代、低收入、学业准备不足的少数族裔学习者提供一种机制,帮助他们就自己的学习和成就进行对话,从而发挥赋权工具的作用。9)提供一种机制,通过这种机制,学生可以展示他们的才能,这可以被学生在寻找实习和/或长期就业时用于专业晋升(Buzzetto-More, 2010)。…

The Effect of Varied Visual Scaffolds on Engineering Students’ Online Reading 不同视觉支架对工科学生网络阅读的影响
Pub Date : 1900-01-01 DOI: 10.28945/1299
Pao-Nan Chou, H. Hsiao
Introduction While engaging in knowledge acquisition in online learning environments, especially online text reading, students tend to be disoriented and face a cognitive load problem (Chen & Dwyer, 2003). Under this situation, specific instructional scaffolds should be used to assist learners to comprehend large amount of information (Sharma & Hannafin, 2007). Of those available scaffolds listed in the existing literature, visual scaffolds are regarded as an effective tool to support student learning because human beings are visually oriented (Dwyer, 2007; Norman, 2004). According to Davis (2007), the text-based reading document is still a mainstream instructional material in online learning settings despite the availability of high technologies. As Chen and Dwyer (2003) pointed out, online instructors often employed hypermedia documents as reading materials to support student learning. In order to pursue better instructional effectiveness, high-quality design in online reading materials is necessary. However, whether or not embedding visual scaffolds can enhance students' online reading performance is worthy of exploration. For the background information discussed above, this study aims to explore the in-instructional effectiveness of different types of visual scaffolds embedded in online reading material. Engineering students were chosen as a targeted group. One control group with no visual scaffolds was created. Two visuals, static and interactive visual scaffolds, were developed in an experimental study and serve as two treatment groups. The online reading material was a website that imparts basic science knowledge about the human heart. A post-test, consisting of identification, terminology, and comprehensive tests, was used to measure students' online reading performance. Specifically, the purpose of the study is to evaluate the instructional effectiveness of two types of visual scaffolds for engineering students in an online reading environment. Theoretical Foundation The Concept of Scaffolding Scaffolding is defined as "an adult controlling those elements of the task that are essentially beyond the learner' capacity, thus permitting him to concentrate upon and complete only those elements that are within his range of competence" (Wood, Bruner, & Ross, 1976, p.9). A theoretical foundation behind scaffolding is Vygotsky's zone of proximal development, which emphasizes the role of social interaction in promoting cognitive development and bridging the gap between what learners actually know and potentially know (Sharma & Hannafin, 2007). To date, scaffolding no longer restricts interactions between individuals. It has extended to technological tools and instructional techniques, which are often regarded as scaffolds (Puntambekar & Hubscher, 2005). For example, Zumbach, Reimam, and Koch (2006) designed a feedback-based instructional technique to promote a higher-level thinking during online discussions. The Feature of Scaffold In online learn
在网络学习环境中,特别是在网络文本阅读中,学生在进行知识获取时容易出现定向障碍,并面临认知负荷问题(Chen & Dwyer, 2003)。在这种情况下,应该使用特定的教学脚手架来帮助学习者理解大量的信息(Sharma & Hannafin, 2007)。在现有文献中列出的可用支架中,视觉支架被认为是支持学生学习的有效工具,因为人类是视觉导向的(Dwyer, 2007;诺曼,2004)。根据Davis(2007)的研究,尽管高科技的存在,基于文本的阅读文档仍然是在线学习环境中的主流教学材料。正如Chen和Dwyer(2003)所指出的,在线教师经常使用超媒体文档作为阅读材料来支持学生的学习。为了追求更好的教学效果,高质量的网络阅读材料设计是必要的。然而,嵌入视觉支架是否能提高学生的在线阅读成绩值得探讨。基于上述背景资料,本研究旨在探讨不同类型的视觉支架嵌入在线阅读材料的教学有效性。工科学生被选为目标群体。另设无视觉支架的对照组。两种视觉支架,静态和交互式视觉支架,在实验研究中开发,并作为两个治疗组。在线阅读材料是一个网站,传授有关人类心脏的基本科学知识。后测包括识别、术语和综合测试,用来衡量学生的在线阅读表现。具体而言,本研究的目的是评估两种视觉支架在网络阅读环境下对工程专业学生的教学效果。脚手架的概念被定义为“一个成年人控制任务中那些基本上超出学习者能力的元素,从而允许他专注于并完成那些在他能力范围内的元素”(Wood, Bruner, & Ross, 1976, p.9)。脚手架背后的理论基础是维果茨基的近端发展区,它强调社会互动在促进认知发展和弥合学习者实际知识和潜在知识之间的差距方面的作用(Sharma & Hannafin, 2007)。迄今为止,脚手架不再限制个人之间的交互。它已经扩展到技术工具和教学技术,这通常被视为脚手架(Puntambekar & Hubscher, 2005)。例如,Zumbach, Reimam和Koch(2006)设计了一种基于反馈的教学技术,以促进在线讨论过程中的更高层次思维。在在线学习环境中,Hill和Hannafin(2001)提出了四种类型的支架——程序支架、策略支架、元认知支架和概念支架——可以用来支持学生的学习。程序脚手架帮助学习者使用在线资源,“澄清需求,减少认知负荷”(第45页)。策略脚手架为学习者提供了参与在线任务的替代方法。元认知支架允许学习者“评估他们所知道的以及在学习时该做什么”(第45页)。概念脚手架帮助学习者消化在线信息,促进知识构建。在定向远程学习环境(DDLEs)中,Sharma、Oliver和Hannafin(2007)将定向远程学习框架定义为“帮助学习者更高效和有效地处理和内化课程材料的计划策略和内容结构”(第265页)。从根本上说,DDLEs脚手架是一种旨在提高学生在知识获取方面的学习表现的教学技术。…

The online reading material was a website that imparts basic science knowledge about the human heart. A post-test, consisting of identification, terminology, and comprehensive tests, was used to measure students' online reading performance. Specifically, the purpose of the study is to evaluate the instructional effectiveness of two types of visual scaffolds for engineering students in an online reading environment. Theoretical Foundation The Concept of Scaffolding Scaffolding is defined as \"an adult controlling those elements of the task that are essentially beyond the learner' capacity, thus permitting him to concentrate upon and complete only those elements that are within his range of competence\" (Wood, Bruner, & Ross, 1976, p.9). A theoretical foundation behind scaffolding is Vygotsky's zone of proximal development, which emphasizes the role of social interaction in promoting cognitive development and bridging the gap between what learners actually know and potentially know (Sharma & Hannafin, 2007). To date, scaffolding no longer restricts interactions between individuals. It has extended to technological tools and instructional techniques, which are often regarded as scaffolds (Puntambekar & Hubscher, 2005). For example, Zumbach, Reimam, and Koch (2006) designed a feedback-based instructional technique to promote a higher-level thinking during online discussions.

As the effectiveness of learning objects in enhancing education becomes better understood, it will be critical to more fully develop the predictive characteristics of learning object usage by diverse instructors and their long-term sustainability in learning object repositories. Additionally, the advancement of scholarship in these endeavors – a critical factor for faculty to consider – has frequently been overlooked. In this paper we explore these issues by examining the technical and human aspects of The Library of Crop Technology (http://croptechnology.unl.edu) and other repository models. While studies have been conducted to research the impacts of animations on student learning, teacher perceptions of such learning objects have not been examined. An online survey instrument was created and sent to those who had downloaded animations from the Library of Crop Technology. Data collected indicated that educational, animated, learning objects are an effective and sustainable means of meeting a wide array of educator needs. This study identified a template of science content, organization, creation of interest in the topic, visual appeal, effectiveness for teaching a topic, and ease of use as being important to the overall teacher perception of the learning object’s quality. The very positive evaluation received from the users, coupled with their indication of returning to the site multiple times and recommending it to their colleagues, further suggests that the public repository is a model to continue pursuing. An important, but often overlooked, concept in the development of repositories is the dynamics of long term sustainability and scholarly contributions. A second study researched team development and institutional commitments which play a role in the long term stability of this learning object repository. A model integrating team development, institutional commitments, learning object development and scholarship recognition is proposed.
随着人们对学习对象在促进教育方面的有效性越来越了解,更充分地开发不同教师使用学习对象的预测特征及其在学习对象库中的长期可持续性将是至关重要的。此外,在这些努力中,学术的进步——这是教师考虑的一个关键因素——经常被忽视。在本文中,我们通过检查作物技术库(http://croptechnology.unl.edu)和其他存储库模型的技术和人员方面来探讨这些问题。虽然已经进行了研究动画对学生学习的影响,但教师对这些学习对象的看法尚未得到检验。我们制作了一个在线调查工具,并将其发送给那些从作物技术图书馆下载动画的人。收集的数据表明,具有教育意义的、生动的学习对象是满足教育者广泛需求的有效和可持续的手段。本研究确定了科学内容、组织、对主题产生兴趣、视觉吸引力、教学主题的有效性和易用性的模板,这些模板对教师对学习对象质量的整体感知很重要。从用户那里得到的非常积极的评价,加上他们多次返回站点并将其推荐给同事的指示,进一步表明公共存储库是一个值得继续追求的模型。存储库开发中的一个重要但经常被忽视的概念是长期可持续性和学术贡献的动态。第二项研究研究了团队发展和制度承诺,它们在学习对象存储库的长期稳定性中发挥作用。提出了一个整合团队发展、机构承诺、学习对象发展和奖学金认可的模型。

The Value of Collaborative E-Learning: Compulsory versus Optional Online Forum Assignments 协作式电子学习的价值:强制性与可选性在线论坛作业
Pub Date : 1900-01-01 DOI: 10.28945/1319
Ruti Gafni, N. Geri
Online forum assignments are one of the main tools for collaborative learning. This study examines the impact of compulsory submission on the effectiveness of forum assignments. It compares the grades of 120 MBA students who studied an advanced elective course in a blended distance learning university during the years 2005-2009. Some students were required to participate in a forum assignment and their submissions were graded, whereas other students were similarly asked to participate in a forum assignment but their work was not graded. The findings suggest that the benefits of optional forum assignments are marginal, whereas compulsory forum assignments may improve student performance. The main theoretical contribution of this study is the indication that although the students had a task-oriented attitude and were not engaged in social interaction with regard to the forum assignment, compulsory posting of the assignment on the discussion board, improved their performance. Practically, the findings suggest that publishing student assignments on a course website may improve assignments’ quality and therefore enhance student performance, even if there is no further collaboration or social interaction. This finding is important since creating meaningful collaboration in online environments requires considerable instructors’ efforts in moderating the discussion.
在线论坛作业是协作学习的主要工具之一。本研究探讨强制提交对论坛分配有效性的影响。该研究比较了2005年至2009年期间在一所混合式远程教育大学学习高级选修课程的120名MBA学生的成绩。一些学生被要求参加一个论坛作业,他们提交的作品被评分,而另一些学生同样被要求参加一个论坛作业,但他们的作品没有被评分。研究结果表明,可选的论坛作业的好处是微不足道的,而强制性的论坛作业可能会提高学生的表现。本研究的主要理论贡献是表明,尽管学生在论坛作业方面具有任务导向的态度,并且没有参与社会互动,但在讨论板上强制发布作业可以提高他们的表现。实际上,研究结果表明,在课程网站上发布学生作业可能会提高作业的质量,从而提高学生的表现,即使没有进一步的合作或社会互动。这一发现很重要,因为在在线环境中创建有意义的协作需要教师在调节讨论方面付出相当大的努力。

Developing Learning Objects for Secondary School Students: A Multi-Component Model 中学生学习目标的开发:一个多组件模型
Pub Date : 1900-01-01 DOI: 10.28945/423
Robin H. Kay, Liesel Knaack
Previous research on the development of learning objects have three notable characteristics: a focus on either technical or learning features, but not both, a target audience consisting exclusively of higher education students, and the absence of formal evaluation. This study provides a detailed description and formal evaluation of a multi-component model used to develop five learning objects for secondary school students. Overall, two thirds of the students reported that the learning objects were beneficial, citing a motivating theme, interactivity, and visual qualities as the most important features. However, almost 60% of all students were critical about the learning object quality. Clarity of instructions, help functions and organization/layout presented the most problems. While the development model used in the study emphasized both technical and learning components, the latter was far more important to teachers and students. Key steps that appeared to be beneficial in the development process included a collaborative team approach, understanding the learner, a focus on clear instruction and organization, and using a comprehensive, theoretically supported evaluation metric to examine the quality and benefits of learning objects.
以往关于学习对象发展的研究有三个显著特点:要么关注技术特征,要么关注学习特征,而不是两者兼而有之;目标受众完全由高等教育学生组成;缺乏正式的评估。本研究提供了一个详细的描述和形式化评价的多组件模型,用于开发五个学习对象的中学生。总的来说,三分之二的学生报告说学习对象是有益的,他们认为最重要的特征是激励主题、互动性和视觉质量。然而,几乎60%的学生对学习对象的质量持批评态度。说明的清晰度、帮助功能和组织/布局呈现出最多的问题。虽然研究中使用的发展模式同时强调技术和学习成分,但后者对教师和学生来说更为重要。在开发过程中似乎有益的关键步骤包括协作团队方法、理解学习者、关注明确的指导和组织,以及使用全面的、理论上支持的评估度量来检查学习对象的质量和效益。
