对构建和谐班级的几点感触     

宋志华 《中国教育发展研究杂志》2007,4(4):28-29

一个良好的班集体需要构建和谐的师生关系。新型的师生关系应该是教师和学生在人格上是平等的、在交互活动中是民主的、在相处的氛围上是和谐的．因此，班主任在工作中需要关爱、尊重、研究学生，让学生自主参与，并且改变自己，加强自身修养。  相似文献

Active control of structural vibration by piezoelectric stack actuators   总被引：2，自引：0，他引：2  

牛军川赵国群  胡夏夏 《浙江大学学报(A卷英文版)》2005,6(9):974-979

INTRODUCTION Passive methods have played an important role for a long time (Snowdon, 1973; Nelson, 1982; Pan et al., 1992) in vibration and noise control. However, with inrush of some novel engineering structures and machines, such as super high-speed machine tools, long-span bridges, thin shell structures, micro elec- tromechanical systems and so on, traditional passive control approaches are not efficient enough for con- trolling structure noise and vibration from these novel systems an…  相似文献   

Synthesis of acetals and ketals catalyzed by tungstosilicic acid supported on active carbon   总被引：3，自引：0，他引：3  

Yang SJ  Du XX  He L  Sun JT 《Journal of Zhejiang University. Science. B》2005,6(5):373-377

INTRODUCTION Acetals and ketals are among the most importantperfume materials and industrial materials of organicsynthesis. There are now many methods to synthesizethem. The H2SO4 conventionally used as catalyst infactories (Li and Fan, 1981) causes many problems,such as erosion of equipment, difficulty for af-ter-treatment, low quality of the products, etc. Withthe use of anhydrous copper sulfate (Hanzlik andLeinwetter, 1978), molecular sieve (Wang and Qian,1993), montmorillonite…  相似文献

Non-linear improvement in generic problem-solving skills of university students: a longitudinal study

ABSTRACT

Problem solving has been characterized as one of the ‘employability skills’ due to the high demand for such abilities in a modern workplace. Most universities do not monitor progress of the generic problem-solving skills (PSS) of their students due to a lack of available assessment tools. We used previously reported 15-min tests to measure the generic PSS of students over the first three years of university. More than 600 students participated in this study, including 144 who wrote PSS tests in Year 1 and then again in Year 3 of their studies. Two versions of the PSS test were administered in September and December of both years. We observed a non-linear increase in PSS test scores with a significant growth during the first three months of Year 1, a similar increase over the next 21 months, then no change during the first three months of Year 3. Further studies are necessary to pinpoint the instructional techniques and situational factors facilitating the PSS development of students over the first three years of studies. Moreover, the plateau we observe in the third year indicates that proactive steps by universities and individual instructors are required to advance this important skill set in upper-year students.  相似文献   

Who is the engaged citizen? Correlates of secondary school students’ concepts of good citizenship     

Frank Reichert 《Educational Research and Evaluation》2016,22(5-6):305-332

The opinions about what characterises a good citizen are diverse, yet survey research usually employs variable-centred analytical strategies to examine people’s concepts of good citizenship. The present study builds on a person-centred approach towards good citizenship and validates previously identified types of good citizenship among Australian secondary school students. Following an in-depth characterisation of these types by sociodemographic variables and civic attitudes, this study incorporates multinomial regression analysis to take a closer look at very extreme but practically important patterns. These analyses suggest that students need to believe in the value of civic action to become political enthusiasts and not politically alienated. Civic knowledge may prevent political alienation; however, it is not the ultimate solution as it is negatively correlated with political enthusiasm when controlling for multiple predictors. The results are discussed with respect to their significance for civics and citizenship teaching and learning.  相似文献

Evaluation of creative problem-solving abilities in undergraduate structural engineers through interdisciplinary problem-based learning     

Daniel Patrick McCrum 《European Journal of Engineering Education》2017,42(6):684-700

For a structural engineer, effective communication and interaction with architects cannot be underestimated as a key skill to success throughout their professional career. Structural engineers and architects have to share a common language and understanding of each other in order to achieve the most desirable architectural and structural designs. This interaction and engagement develops during their professional career but needs to be nurtured during their undergraduate studies. The objective of this paper is to present the strategies employed to engage higher order thinking in structural engineering students in order to help them solve complex problem-based learning (PBL) design scenarios presented by architecture students. The strategies employed were applied in the experimental setting of an undergraduate module in structural engineering at Queen’s University Belfast in the UK. The strategies employed were active learning to engage with content knowledge, the use of physical conceptual structural models to reinforce key concepts and finally, reinforcing the need for hand sketching of ideas to promote higher order problem-solving. The strategies employed were evaluated through student survey, student feedback and module facilitator (this author) reflection. The strategies were qualitatively perceived by the tutor and quantitatively evaluated by students in a cross-sectional study to help interaction with the architecture students, aid interdisciplinary learning and help students creatively solve problems (through higher order thinking). The students clearly enjoyed this module and in particular interacting with structural engineering tutors and students from another discipline.  相似文献   

从“积极政府”到“自制政府”:新时代现代大学治理中的政府画像     

凌健  侯春笑 《复旦教育论坛》2020,18(2):32-38

政府干预是影响现代大学治理的重要变量。作为一种干预形态,"积极政府"的定位源于特定的时代命题,其行动产生了预设的积极效用,有力推进了中国大学的现代化进程,但同时也带来了制度赶超、政策过剩、大学能力单一等消极效应。新时代的国家治理转型为政府善治大学提出了新愿景,面对如何营造有利于大学内涵式发展的外部环境、如何避免现代大学制度落地过程中的悬置、如何引导大学真正服务社会等挑战,政府应从"积极介入"走向"自我节制",通过规范介入的空间、减少介入的主体、变革介入的方式、降低介入的动力等策略描绘出理想的"自制政府"画像。  相似文献
