数据挖掘在网络学习者学习特征分析系统中应用 总被引：9，自引：0，他引：9
目前我国的网络远程教育只突出了它的信息传播功能，即网络资源的共享和学习者远程学习的时空灵活性，而忽视了另外一个重要的特点——个性化教学。建立学习者学习特征分析系统是实现个性化教学的重要保障。本文讨论了如何应用数据挖掘技术进行学习者学习特征分析的过程，并结合实际工作，绘出了学习者学习特征分析系统的结构图。 相似文献

泛在学习中自适应学习系统模型研究 总被引：1，自引：0，他引：1
泛在学习能够给予学习者随时发生的学习提供支持,更有利于培养和激发学习者的学习兴趣,促使学习者自主研究学习。从"区别传统学习系统"一点出发,考虑学习者学习风格,结合泛在环境下灵活自由的学习形式,提出了一个自适应学习系统模型。该模型主要是体现高等教育学习者自主探究学习,根据环境感知和学习者的学习偏好和认知结构、情感倾向,提供不同资源以满足学习者的需求。最后对泛在学习中自适应学习系统进行思考,为以后研究提供改进建议。 相似文献

网络化学习（E-leaning）是指通过因特网或其他数字化内容进行学习与教学的活动。其内涵为：网络作为学习学习的工具；网络做为学习的对象；网络作为学习的资源；网络做为学习的环境。目前国内外对网络化学习的研究主要集中在网络化学习资源、网络技术、网络化学习环境、网络化学习策略、网络化学习的评价以及网络化学习模式等的分析与研究上，而忽略了影响网络化学习效果和效率的另一个重要方面——学习者之间的情感交流。 相似文献

接受式学习，是指学习者占有传授者提供的经验，把前人创造的经验变成自己的经验，使自己成为辨认事物、处理问题的工具。在这种学习方式中，学习者所学的知识基本上是由传授者以定论的形式传授给学习者的，学习者不需要事事亲身经历，只需要将所学材料内化，以便今后可以利用。 相似文献

当前远程学习的课程设计普遍存在目标设计缺失的现象,这可能源于人们对远程学习目标“是何”及“如何”运作的认识不够,从而导致学习者面临学习失败的风险。探讨远程学习目标“是何”是研究“如何”的先决条件。远程学习目标结构研究,旨在探讨远程学习目标的类别及其关系。活动理论是一种重在把活动系统作为分析单位的分析模式,迄今为止经历了“中介说”、“层次说”、“要素说”三代发展历程,为人们重新认识远程学习的目标结构提供了新的视角。它提示人们可以从活动层中的“过程”与“结果”维度去认识远程学习的目标结构,并从行动层中提取描述远程学习过程目标的5个要素：主体、客体、工具、行为、时间,建构出远程学习“过程一结果”目标结构的分析框架。远程学习目标结构可以帮助学习者在学习之初对远程学习结果及实现结果的过程做出规划,为之后的目标实施及评价提供保障,规避学习失败的风险。 相似文献

This special issue was designed to promote an integration of mobile and psychological theories of learning by inviting empirical research that draws upon both theoretical approaches to guide investigation into learning involving mobile devices. Five empirical articles illustrated how mobile devices afford resources to learners and how new channels of data afford researchers new insight into learning processes. Authors of two invited commentaries note the challenges involved in researching mobile learning, which unfolds across multiple contexts and can involve novel tools, multiple learners, and instructors and experts. These authors propose a taxonomy that can organize research that investigates interactions amongst learners, instructors, experts, and tools across one or more physical contexts, as well as a research agenda that would empirically test and refine assumptions made by mobile learning theorists. In this commentary, the editorial team proposes that mobile and psychological theories may be improved through convergence. Theories of mobile learning can be advanced by adopting practices previously employed to refine psychological theories of learning, whereas conducting research using mobile devices (and the data they provide) can further refine psychological theories of learning. We illustrate these positions with examples, and consider how instruction must be designed and how learners must be prepared in order to benefit from learning using mobile technology. 相似文献

There is not a unique attitude towards the implementation of digital technology in educational sceneries. This paper aims to validate an adaptation of the DeLone and McLean information systems success model in the context of a learning management system. Furthermore, this study means to prove (1) the necessity of segmenting students in order to fit the model more accurately and (2) the impact of other new Internet tools on students’ perceptions with regard to learning management systems. Partial least squares has been used to analyse the measurement and the structural model. Subsequently, the Finite Mixture Partial Least Squarestechnique has been employed to examine unobserved heterogeneity and to find users’ segments. The results of this research indicate that to segment between two groups of students is especially useful in order to improve the understanding of the success of a learning management system. This segmentation is made according to the importance which the students attribute to the new Internet tools to support their learning. 相似文献

AbstractThe use of technology to support learning is becoming ubiquitous in Africa. However, technology is more often used to distribute information rather than as a tool to mediate learning. The work presented here on a programme for Zambian community school teachers (non-traditional students) illustrates how learning design allied to appropriate theoretical concepts make use of technology to mediate learning. The objective of this course was to support Zambian community school teachers, with little formal teacher education, to use interactive methods to support their teaching practices. The research makes use of a constructivist-hermeneutic-interpretivist-qualitative paradigm to critically evaluate the learning design by experts. A social constructivist framework for learning design and technology mediation was used to create and evaluate learning resources. The work illustrates how a distance education paper-based course design is enhanced by the use of contemporary learning theory and digital technology to model good interactive classroom practice. 相似文献

移动通信技术的发展使依托移动设备的微型学习成为可能,满足了成人学习者短小、松散、实用的学习需求。微型学习的理念和移动学习融为一体,为提高学习效率和质量提供了保证。然而,从目前的现状来看,对微型学习课程设计原则的研究非常有限。要充分发挥微型学习＂短小、精悍、实用＂的特点,尤其需要针对成人学习的特点以及移动设备的特征对课程设计原则进行深入研究。通过对移动学习的相关学习理论、已有的课程设计原则进行了研究和分析,提炼微型学习课程设计的原则和要素,为形成符合成人移动学习特点的课程设计提供参考,使成人学习者能够利用＂零碎＂时间进行学习,发挥移动设备和技术的特点和功能,使新媒体技术支持下的学习变得更加高效。 相似文献

教学范式向学习范式转型之际,重新设计作为教育变革媒介的学习空间成为重要的研究命题。然而,当前对学习空间尚未形成清晰的认知。文章首先立足学习空间与学习环境交叉混用现状,通过概念辨析得到学习空间是中介物,是学习发生的间接支持条件,学习环境是刺激物,是学习发生的直接支持条件;其次,通过认识发生过程与生物学蛋白质合成过程的类比,得到学习空间具有“居所”与“转运”双重属性;最后,基于双重属性提炼出学习空间的结构要素,“居所”属性锁定的实体场所和虚拟场所,“转运”属性锁定的工具性客体和对象性客体。 相似文献

Sociocultural approaches emphasize the systemic, context-bound nature of learning, which is mediated by other people, physical and conceptual artifacts, and tools. However, current educational systems tend not to approach learning from the systemic perspective, and mostly situate learning within classroom environments. This design-based research aims to seek answers to these challenges by enhancing the use of museum objects and inquiry tools in learning through developing a new kind of virtual environment. By using learning objects that represent physical objects, the students can develop their own research questions, and choose related museum artifacts and inquiry tools with which to find answers to their questions during forthcoming museum visits. This study aims to examine what kinds of learning systems emerged when three different student groups collaboratively designed their visits to the Finnish Forest Museum based on their own interests and afforded resources in the learning environment. Data analysis indicates that a tool-driven system typically seems to represent the approach of primary school students, with an object-driven system for technical college students, and a strategic, research-question-driven system for teacher-education students. When considering the desired effects of technology and open environments on emerging learning systems and processes, the results of the study suggest that self-organization and free choice do not necessarily lead to research-question-driven learning processes, unless the variation in student approaches, design-process scaffolding, and paying attention to the social arrangements, and to the use of tools during the implementation of inquiry activities are all taken into account. 相似文献

Developing a university course for online delivery based on learning objects: from ideals to compromises 总被引：1，自引：0，他引：1
A course instructor and his assistant at Athabasca University investigated whether the process of transferring interoperable learning objects from online repositories facilitated course production, both pedagogically and economically. They examined the efficiency of the objects‐assembly method from several perspectives while developing an online university course based on learning objects for this, one of Canada's leading online and distance education institutions. The two researchers examined issues that confronted them as they gathered, assessed, repaired, assembled and created learning objects. When their search for suitable objects appeared fruitless, they questioned assumptions made by theoreticians and visionaries about pedagogical and economic efficiencies associated with the objects‐assembly metaphor and production. They highlighted this metaphor's failure to guide their course design based on learning objects in a climate of uncertainty and explained the nature of the compromise that eventually compelled them to acquire a proprietary online delivery system. 相似文献
