设计最优化学习环境:OECD研究的视角

设计最优化学习环境是面向21世纪的"适应性教育"所提出的要求,它有助于学习者形成"适应性能力"。OECD的研究认为,要善于提炼新学习的基本特征,这就是主动建构、自我调节、情境相依和协同努力。与此相连的新学习本质观主张:在学习过程中学习者应积极投身于学习活动中,持续努力,确保成功;重视学习者已有知识,强化知识组织,形成合理的知识结构与线索,形成一种完整的知识图景;遵循信息加工能力的限制条件,重视学习中动机、情感与认知的动态交互;培养学习者理解概念、通晓程序和自我调节的协调能力,致力于达到学习迁移的效果。为此,设计最优化学习环境的基本原则是:生本教学、自我调节;注重交往、善用合作;关注动机、情知相依;利用旧知、因人施教;富有挑战、减负增效;紧扣目标、不断反馈;学科融合和内外互通。     

在线协作学习过程中社会临场感的社会网络分析

已有的研究和实践证明,社会临场感有助于降低学习者在线学习过程中的孤独感、提升学习满意度和促进虚拟学习社区的建立。社会临场感与交互的关系十分密切,以往研究者主要借助内容分析方法或调查问卷来分析两者之间的关系,注重测量个体的意见和主观的感知,但无法反映社会临场感随时间发展变化的动态特征。社会网络分析(SNA)的中心度、密度、中心势、派系等参数能够较为合理地表征在线协作学习中师生的交互过程特征,为研究这一问题提供了新的思路。通过对一门网络课程实施期初、期中和期末三个阶段师生在线论坛中的交互过程与行为进行定量和可视化的社会网络分析,结果显示:学习者在不同学习阶段的社会临场感存在显著差异,交互和社会临场感之间具有十分紧密的联系,个体的社会临场感会随时间的发展而变化。社会网络分析有助于理解在线学习环境中社会临场感的形成和发展变化,有助于教师改进教学,提升网络教学的质量。     

Joining the goblins: fictional narratives and the development of student‐teachers’ reflection on practice in the further education sector

This paper explores ways in which student‐teachers in the Lifelong Learning sector are able to draw on fictionalised accounts of their own teaching practice experiences in order to gain a clearer understanding of their models and expectations of professionalism, and of how they, as individuals, locate their current position within the profession as a community of practice. It argues that the translation of experience into fiction – in this case specifically in the form of fairy tales – can be usefully applied in order to enhance and encourage reflection on practice as part of an action research cycle. Drawing on the evidence gathered, the paper goes on to suggest that student teachers’ main preoccupation at this stage of their development is not so much with meeting ‘standards’ of professionalism as with questions of behaviours and practices that will lead to a sense of belonging and acceptance; and with the need to transform their status, in relation to the profession, from that of outsider to insider.     

The Comparative Effects of Prediction/Discussion‐Based Learning Cycle,Conceptual Change Text,and Traditional Instructions on Student Understanding of Genetics

The present study examined the comparative effects of a prediction/discussion‐based learning cycle, conceptual change text (CCT), and traditional instructions on students' understanding of genetics concepts. A quasi‐experimental research design of the pre‐test–post‐test non‐equivalent control group was adopted. The three intact classes, taught by the same science teacher, were randomly assigned as prediction/discussion‐based learning cycle class (N = 30), CCT class (N = 25), and traditional class (N = 26). Participants completed the genetics concept test as pre‐test, post‐test, and delayed post‐test to examine the effects of instructional strategies on their genetics understanding and retention. While the dependent variable of this study was students' understanding of genetics, the independent variables were time (Time 1, Time 2, and Time 3) and mode of instruction. The mixed between‐within subjects analysis of variance revealed that students in both prediction/discussion‐based learning cycle and CCT groups understood the genetics concepts and retained their knowledge significantly better than students in the traditional instruction group.

Cognitive load and knowledge sharing in Learning Networks

Learning Networks (LNs) are online social networks designed to support nonformal learning; they are therefore particularly suitable for self-directed learners. In LNs, learners need to construct knowledge through knowledge sharing with other participants. However, without support, learners have to organize knowledge sharing themselves and this could induce extraneous cognitive load. When working on complex learning tasks, this organizing process could have a detrimental effect on knowledge construction. To optimize cognitive load, we propose using a peer support system that applies the mechanisms of peer tutoring to support knowledge sharing. Its mechanisms reduce, we argue, the extraneous load imposed by having to organize knowledge sharing as well as induce germane load by directing the freed-up cognitive capacity to processes that contribute to knowledge construction.     

虚实融合学习环境:概念、特征与应用

随着现代信息技术的发展和教育教学理念的转变,基于网络和多媒体的"虚拟"学习环境已经被人们熟悉并部分取代基于课堂的"现实"学习环境。虚拟和现实的学习环境各有利弊,前者有利于学习者使用丰富的数字化资源开展跨地域的协作学习、拓宽知识视野,后者有利于学习者的临场体验和实际操作能力培养。在分析相关文献和现有学习环境特征研究的基础上,分析了"虚实融合学习环境"的内涵与特征,对虚拟、现实以及虚实融合的学习环境进行比较,并就若干典型的虚实融合学习环境及其教学应用情况进行了分析,其中包括:校园环境信息观测与研究性学习、GLOBE全球性学习与观察、虚实融合的机器人教育、数字化探究实验室。     

影响教育虚拟社区中学习动机激发因素的实证分析

教育虚拟社区中的学习动机是学习者通过自我调节,使自身的内在要求与学习行为的外在诱因相协调,引起和维持学习者在教育虚拟社区中的学习活动,并激励、指引学习者的行为朝向一定学习目标的内部心理状态。在基于课程＂学习科学与技术＂的教育虚拟社区学习实践的基础上,实证分析了教育虚拟社区中学习动机激发的影响因素,通过描述性统计、回归分析、因子分析和聚类分析发现：教师因素、学习者因素、环境因素和文化因素是影响学习者在教育虚拟社区中学习动机激发的四大要素,学习者在教育虚拟社区中学习动机的激发有赖于以上各因素协同作用的发挥,由此提出了影响教育虚拟社区学习动机激发因素的分析模型。     

情感计算在网络远程教育系统中的应用：功能、研究现状及关键问题

情感能力是人类智能的重要标志,情感的缺失会影响网络远程教育的教学质量和学习者的学习效果。情感计算是和谐人机交互与人工智能领域中新的研究方向。在网络远程教育系统中应用情感计算理论与技术,可以进一步优化网络远程教育的功能,帮助教师监测远程学习者的情感变化,调整教学策略和方法,实时给予学习者情感反馈,使教学质量达到最佳。目前国内外情感计算在远程教育方面的应用研究还处于起步与探索阶段,所构建的远程教学系统对远程教学中师生情感生理特征与心理特征、多模情感信息融合机制及网络虚拟人机情感交互特性等考虑不足,系统原型在情感合成与表达、智能人机情感交互实现上存在着很大的难度。因此,构建与人类情感系统相吻合的、自然和谐的、人性化和智能化的网络远程教育系统,需要有效解决师生面部表情、语音情感特征信号的准确识别与提取,师生多模情感信息融合机制与和谐人机情感交互技术等关键问题。
