“饭圈”主要是以明星艺人的粉丝为主导所形成的一种圈层化人群。他们高度活跃在各大网络社交平台,创生出一种全新的生活方式与圈层文化。当前国内饭圈呈现出年龄低龄化、趣缘圈层化、行为组织化和情绪极端化等特征,对网络主流意识形态带来较大冲击,亟需加以正确引导。饭圈作为一种边缘的亚文化群体,对网络主流意识形态的潜在风险主要体现为：消费主义盛行、流量至上逻辑、网络暴力恣肆、境外势力渗透、价值导向虚无等问题。为此,本文提出了一些对策,以期能够规避饭圈文化对网络主流意识形态的潜在风险,进一步发挥主流意识形态对青年亚文化群体的主导性、向心力、凝聚力和影响力。 相似文献

根据教育的形式、类型、层次及内容等标准划分,将西南民族科技教育系统划分为八个子系统。各个子系统均担负着西南民族科技教育的任务。然而,不容乐观的是该系统内部存在着诸多不协调的因素,这些不协调的因素严重影响了系统整体功能的发挥。协调系统内部各个因素之间的关系对母系统整体功能的发挥有着举足轻重的作用。 相似文献

基于系统理论的教育技术本体研究 总被引：1，自引：1，他引：0
针对教育技术本体构成问题,本文借鉴系统理论进行了深入的研究.通过对系统理论和教育技术系统的客观情况的分析,依据系统与环境之间的基本关系的原理,得出了教育技术系统是按照人的需求、目的构建教育系统及其要素的转换系统这一意见性结论.通过分析这一结论与当前一些结论存在的差异,提出了认识教育技术的新视角.通过对教育技术系统的深入分析,借鉴一般系统理论的研究,得出了教育技术系统是由教育技术输入子系统、教育技术运作子系统、教育技术输出子系统、教育技术协调监控子系统构成.同时本文探讨了四个子系统的构成要素及运作机理,为教育技术系统的持续发展和不断完善提供了可供参考的意见. 相似文献

系统论、协同论是协同理论的基础。协同理论是将横断科学的研究方法用于声乐演唱教学研究的尝试。本文从系统论的角度出发,把包括生理系统和心理系统,教与学等子系统及各子系统组成的声乐演唱教学看成为一个系统。在此基础上,使声乐教学的过程依据协同论,发现心理系统、生理系统,学系统和教系统及各子系统的子子系统之间的运动关系具有合作、同步、协调、促进、互补的关系,这个发现也是通过结合它们的运动规律而产生的协同运动,符合协同论原理,从而达到最终目的是产生该系统的协同效应。 相似文献

In the natural sciences, collecting, cataloguing, and comparing living specimens have long been a popular, collaborative mode of discovery and learning. New species are discovered, and the relationships between species are theorized. From Aristotle's “History of Animals” to Darwin's “On the Origin of Species”, and beyond, this process of learning through expedition has yielded bountiful knowledge and insights to students of science. In this paper, we propose that expeditionary learning can be applied to a softer science: the field of information systems. In the field of information systems, specimens (information systems) are created by humans, evolving with great speed. Expeditionary learning—where students collaboratively discover, catalog, and compare rapidly evolving information system specimens—is an innovative approach for learners in the IS field, and is effective in increasing IS program visibility and delivering significant, measurable community impact. Our results indicate that learning by expedition has a strong, positive community impact through educating external learners (such as high school and community college students, and the general public), and compares favorably to conventional experiential and service learning styles. Though expeditionary learning does not yield improved course evaluations, we demonstrate that learners’ perceived self‐knowledge and intentions to pursue the subject area are improved. 相似文献

As the sophistication of technology has increased, so has public demand for quality. This expectation of quality has occurred across a broad range of products and systems, including education. To meet the demand for quality, many products and systems (including educational ones) have become increasingly complex. Within education there are also other factors which have driven up levels of complexity. These factors include increased diversity in the student body, a greater emphasis on collaboration and the drive to replace simple “delivery models” of teaching. It is well known from other fields, though, that as systems become more complex, they become more vulnerable to failure. For this reason, a formalised methodology known as “systems engineering” is often applied in industry to the management of large systems. The author argues that the use of systems engineering concepts in education would be likely to reduce failure rates and improve quality. This is particularly so in large-scale complex learning systems. The paper also discusses some implications of trying to use systems engineering methodology in modern educational systems. 相似文献

A proportion of children with physical impairments experience significant difficulties in communicating with others and may be recommended augmentative and alternative communication (AAC) systems such as speech synthesizers and symbol charts to support ‘natural’ communication skills. However, AAC systems are often under-utilized. Parents have identified barriers to AAC system use to include the organization of speech and language therapy. Speech and language therapists are developing services to school-aged children in response to changes in education, health reforms and models of speech and language development. However, there is little evidence for commissioners of children's services about what constitutes ‘enough’ or ‘good’ speech and language therapy. This paper examines speech and language therapy provision to 23 children using AAC systems in six London authorities. Research strategies include documenting the amount, type, organization and objectives of provision. Evidence for collaboration between school staff and therapists is explored, analysis is made of child characteristics associated with provision and criteria for decision-making documented through interviews with therapists. However, little conjunction exists between what therapists said guided their decision-making concerning provision and observed provision. For the children surveyed in this study it seems that that provision in amount of therapy is related to educational placement rather than individual needs. 相似文献

Despite the need for information technology knowledge in the business world today, enrollments in information systems (IS) courses have been consistently declining. Student performance in lower level IS courses and student assumptions about the level of difficulty of the courses seem to be reasons for lower enrollments. To understand how student motivation may explain learning outcomes in introductory IS courses, this study investigates the impact of intrinsic and extrinsic academic motivations as framed by self‐determination theory on two measures of learning outcomes: (1) student self‐reported measures of learning and (2) actual grades obtained in courses and course components. Using 269 student responses collected in a second‐year undergraduate core course and a first‐year MBA core course, both of which are offered in a traditional face‐to‐face classroom environment, study hypotheses are analyzed. Results indicate that the motivational model explains both the affective and cognitive perceptions of learning held by students. In examining overall grades and grades in course components, the motivational model, however, was unable to sufficiently explain student performance. Data also indicate that there are significant differences between undergraduate and graduate students in terms of their motivation and learning outcomes. 相似文献

A comprehensive conceptual framework is developed and described for evolving recommender‐driven online learning systems (ROLS). This framework describes how such systems can support students, course authors, course instructors, systems administrators, and policy makers in developing and using these ROLS. The design science information systems research approach was used to develop the framework. The ROLS framework incorporates both the cognitive and situative perspectives of the constructivist paradigm of learning. Research propositions are developed to highlight new research opportunities for these systems. The framework demonstrates how various components of an evolving ROLS can be integrated to provide potential benefits for all users. 相似文献
