船舶阻力教学实验的计算机模拟与仿真 总被引：6，自引：3，他引：6
在本科专业教学过程中，船舶阻力教学试验的计算机模拟与仿真，是基于实船和船模阻力分析预报的基本理论，运用Visual Basic程序设计语言与数据库技术，对本船模试验水池已做过的各类船模阻力试验数据进行编程，使学生不受实验场地、设备和空间的限制，利用虚拟实验系统进行船舶阻力实验模拟与仿真，克服了船模试验的设备庞大和高成本的限制，本系统可成为船舶阻力教学实验辅助工具。 相似文献

“双减”是推动义务教育高质量发展的重要举措。回归育人初心是“双减”的价值追求。然而在实施中，“双减”却遭遇了多元主体认知偏差与价值取向间冲突形成的心理阻力、实施的制度供给不足与路径依赖形成的制度阻力、多元主体观念与诉求不对称形成的价值阻力、“双减”政策的可操作性不强与伦理性薄弱的实际阻力。化解上述阻力的有效策略是匡正传统育人观念，提升综合教学素养；优化政策内容，加大资源投入；完善制度供给，推动政策深入实施；建立政策动态反馈与专家决策机制，常态化动态调整配套方案。 相似文献

对于游泳运动员水感的问题已引起越来越多的教练员的重视。水感好已被公认为是优秀游泳运动员必须具备的条件。游泳运动员的水感虽然与天赋有关,但也要经过科学、系统地训练,才能逐渐地得到挖掘和提高。笔者认为各种形式的曲线划水练习,不规范游进练习和与游泳技术要求相反的游进练习,是迅速培养、提高游泳运动员水感的有效方法。 相似文献

教师文化作为学校文化的核心内容,是课程实施的重要影响因素.教师的生活境遇影响并决定着他们的意义世界,从而也影响着他们的教育教学行为及课程与教学决策.J中学的教师文化故事向我们展示了学校变革过程中可能遭遇的阻力.不正确看待并及时消解这些阻力,将导致学校向消极方向发展,并最终影响课程实施的成败. 相似文献

Student resistance can be a very important problem for the instructors in universities. Student resistance includes the conscious
and preplanned behaviors towards the information presented to them in the classroom and the institutional practices. Typically,
student resistance takes the form of passive or active non-compliance with roles and outputs expected of them as students.
The purpose of this paper is to investigate the effects of hidden curricula on student resistance. The research was conducted
on senior undergraduate students in a Turkish University, in the Department of Psychological Counseling and Guidance. Given
the exploratory nature of this investigation, a case study methodology was employed. Data was collected from official documents,
class observations, and interviews. The results of this research indicated that the students demonstrated resistance to some
dimensions of the hidden and delivered curricula. Specifically, while the students showed resistance towards the delivered
curriculum and ‘banking education’, they did not show similar resistance to symbolic violence and the ‘warming-up’ process. 相似文献

In this article, taking three selected works by the Danish artist Julie Nord as my point of departure, I will analyse and discuss the role of art in educational theory and practice. In this analysis and discussion I present two concepts, ‘resistance’ and ‘undecidability’, which are rooted in the theories of Dutch professor of education and director of research Gert Biesta and the French philosopher Jacques Derrida, respectively. The two concepts are used to analyse the three works of art and then come to grips with the empirical part of the study. The empirical part explores how a Danish fifth‐grade class (ages 11–12) interacts with works of art characterised by these very things, resistance and undecidability. The point the article makes is that it is not always what is easy and unambiguous that offers the best conditions for learning and gives school pupils a desire to learn. Rather it is often what is full of resistance and is difficult to decipher and understand. 相似文献

心理治疗阻抗现象研究评述 总被引：3，自引：0，他引：3
阻抗是指来访者在心理治疗过程中表现出来的反抗性、不服从、不接受或不配合治疗、缺乏治疗动机等心理现象。阻抗产生的原因既可能是来访者自身的因素,也可能是治疗师的因素。精神分析理论、行为主义、人本主义和认知心理学对阻抗有着不同的解释。阻抗测量量表分为状态阻抗量表和特质阻抗量表两类。为了提高干预的有效性,治疗师在对来访者进行治疗时,应充分考虑其阻抗水平并以此为基础为来访者设计相应的干预计划。指导性干预对阻抗水平较低的来访者干预效果最好,而非指导性干预对阻抗水平较高的来访者效果最好。将来的研究应进一步完善阻抗测量工具和研究方法,深化阻抗成因和影响因素的理论研究。 相似文献

The internationalization of higher education has resulted in the growth of English-medium instruction (EMI) practices and research. The existing EMI research has documented learners’ favorable attitudes toward EMI but not necessarily its practices. Learners’ dissatisfaction has not been viewed as a form of resistance. Through the notion of learner resistance that underscores agency in defiance, this study examined the occurrences of learner resistance and the reasons for it by investigating Chinese learners’ experiences in an undergraduate business English-taught program in Taiwan. Multiple sources of data, including interviews, stories, and class observations, were gathered for analysis. The findings showed that most Chinese learners resisted an unhelpful curriculum, pedagogy, and context. Their resistance may be related not simply to academic disciplines but more importantly to a Confucian Heritage Culture of learning. Such findings highlight learner agency in resisting actions and call for further investigation into potential learner resistance in EMI practices. 相似文献
