The Efficacy of Using Diagrams When Solving Probability Word Problems in College   总被引：1，自引：1，他引：0  

Brian D. Beitzel  Richard K. Staley 《Journal of Experimental Education》2015,83(1):130-145

Previous experiments have shown a deleterious effect of visual representations on college students’ ability to solve total- and joint-probability word problems. The present experiments used conditional-probability problems, known to be more difficult than total- and joint-probability problems. The diagram group was instructed in how to use tree diagrams to solve conditional probability problems; the equation-only group was instructed only in the formulation of equations. Results indicated that the diagram group outperformed the equation-only group on a posttest of 10 near- and far-transfer problems given immediately and as long as 1 week later (Experiment 2). In addition, when rating their experience with the training phase the equation-only group reported significantly higher levels of frustration and lower levels of perceived success than the diagram group.  相似文献   

一种基于关系视频盲水印算法     

鲁晓辉 《宁波职业技术学院学报》2015,(3)

针对视频水印的特征,提出一种利用视频帧采样点均值曲线相交性确定嵌入帧的方法：在水印信息嵌入时,利用嵌入帧三个亮度最大分块位置关系和DC值大小实现每帧2bit信息的嵌入。实验证明,该算法对常规攻击具有良好的鲁棒性。  相似文献   

电影海报多模态话语分析——以《禁闭岛》电影海报为例     

林雯 《渭南师范学院学报》2015,(1):93-96

电影海报利用图像、颜色、文字等多模态来构建意义,是典型的多模态语篇。文章以Kress&Van Leeuwen的视觉语法理论框架为指导,尝试从海报的再现意义、互动意义和构图意义三个方面对电影《禁闭岛》的宣传海报进行多模态话语分析,探讨三者是如何通过言语符号和视觉符号的共同作用来构建语篇的整体意义的。  相似文献

人类命运共同体研究的发展进路与思考--基于CiteSpace知识图谱的可视化计量分析     

刘培东  吴志成 《教学与研究》2022,(1):70-81

借助文献计量工具对人类命运共同体研究进行可视化分析发现,围绕这一主题的研究进路可分为初始起步、快速发展和深化拓展三个阶段,以思想理念溯源、逻辑框架分析、价值意义阐释、实践路径探索为主要研究内容,以国际传播和话语权、中国特色大国外交实践整合、国际秩序和全球治理变革互动以及实践挑战和现实路径为前沿动向,并逐渐形成以马克思主义为主,涵盖政治学、社会学、法学等多学科参与的学术综合体。在人类命运共同体理念的重要性、必要性和紧迫性凸显的大变局时代,应进一步厘清基本概念、拓展研究视角和研究方法、加强研究力量整合和支持、加强对不同国家的认知和态度研究,深化理论研究和实践拓展。  相似文献   

Analysing Creative Design Process: A Set of Tools to Understand Activity in its Socio-cultural and Historic Context     

Brenda Saris  Stephanie Doyle  Judith Loveridge 《The International Journal of Art & Design Education》2023,42(3):439-453

Previous theoretical frameworks used to research and explain creative design processes tend to privilege individual expression and not address the context in which the process occurs. This is problematic due to the ways in which creative activities are embedded in and shaped by socio-cultural and historic contexts. In this article we focus on the ways in which cultural historic activity theory (CHAT) and its analytical activity systems can be used to reveal creative processes in context. We draw on the tools and concepts of CHAT and data from a study of visual communication design (VCD) students and lecturers situated within a transnational higher education (TNHE) context at a university in China. An analytical framework was constructed to research practices used in creative design process learning. The dynamic nature of CHAT offers design process research methods a set of analytical tools to capture the powerful parts played by artifacts and interactions within specific sociocultural and historic learning contexts.  相似文献   

Teachers Curating Virtual Exhibitions for Learning Visual Arts: A Study of Impact and Effectiveness     

Cheung-On Tam  Claire Ka-Yan Hui 《The International Journal of Art & Design Education》2023,42(3):469-485

Although visual arts teachers have free access to high quality online artwork images offering them immense teaching resources, making meaningful use of them remains a pedagogical challenge. During the COVID-19 pandemic, the transition from face-to-face to online teaching caused an immediate need for teachers to enhance their digital competencies and technological capability for planning and delivering a blended art curriculum. Herein, I propose a ‘teacher-curator pedagogy’ via a study in six primary and secondary schools in Hong Kong to assess its effectiveness. The study took place in the academic year of 2021-22 with 331 student participants. The proposed pedagogy puts visual arts teachers in the role of ‘digital curators’ who create virtual exhibitions for teaching art appreciation and artmaking. This paper addresses the theoretical framework, implementation strategies, and the results of the study highlighting its effectiveness, impact and limitations on teaching when using teacher-curated virtual exhibitions in both physical and virtual learning contexts. It was found that the technological capacity and confidence of the teacher participants was enhanced through the use of online resources and virtual exhibition tools. Making use of the 3D presentation of exhibits in themes and context through digital content curation, the teachers engaged students with deep interaction through the blending of online and face-to-face teaching. However, the proposed pedagogy was limited by the high demand of training and preparation work, hardware and software support, and difficulties in assessing and monitoring learning beyond class.  相似文献   

Integrating Creative Thinking Skills Pedagogies into a Higher Education Visual Arts Course     

Cheung On Tam 《The International Journal of Art & Design Education》2023,42(1):16-32

Although there has been increasing international emphasis on creativity in education, many creativity training programmes have focused on enhancing students' creative thinking skills with few studies on how these skills can be integrated into the teaching of subject disciplines. As a member of a Community of Practice project that ran from spring 2021 to summer 2022 at my university, I worked with ten university teachers from multiple disciplines to develop and implement instructional strategies to foster students' creative thinking skills. The paper documented the development, implementation and evaluation of creative thinking skills teaching strategies for a higher education course in visual arts. Both the development of the teaching strategies and the measurement of the impact on student learning have undergone vigorous research procedures and made reference to the existing literature. The effectiveness of the activities was assessed using multiple methods including the Torrance Test of Creative Thinking, a self-report inventory, and a focus group interview. The results indicated the new learning activities enhanced students' creative thinking skills. They also showed that creativity can be developed through teaching while revealing that playfulness, freedom and structure, group interactions, and problem-solving activities are beneficial for the development of creative thinking skills. Readers may better understand the different ways in which creative thinking skills instruction materials can be developed and incorporated into teaching of visual arts by making reference to the strategies suggested and the process of development in the paper.  相似文献

考虑视觉感官舒适度的园林建筑层次设计     

张入心 《科技通报》2014,(9)

利用传统算法在进行园林建筑设计的过程中,由于园林建筑层次受到设计人员主观因素的影响较大,难以进行准确的层次提取,造成设计效率和园林建筑层次感降低。为此,提出考虑视觉感官舒适度的园林建筑层次设计方法。根据韦伯-费普勒相关原理,建立园林中不同建筑物数目与视觉感官舒适度模型。针对模型中不同建筑物的主要特征进行提取,获取不同建筑物主要特征之间的映射关联性,从而完成视觉感官舒适度的园林建筑层次设计。实验结果表明,利用本文算法进行园林建筑层次设计,能够显著降低设计时间,提高园林建筑的层次感,效果令人满意。  相似文献
