“个人-集体”创新及其效率改进:一个实验研究     

秦永恒  万迪昉  姜帆 《软科学》2011,25(1):75-79

组织中总是存在着由于个体理性与集体理性的矛盾造成的困境。首先分析了"个人-集体"创新模式可能产生的问题,然后验证了这种困境的存在,并发现效率的降低是一个动态的过程。进一步证明,组间竞争可以以较低成本显著改善以上困境。  相似文献

Project-based learning in engineering design in Bulgaria: expectations,experiments and results     

Regina Pavlova Raycheva  Pavlina Minkova Vodenova 《European Journal of Engineering Education》2017,42(6):944-961

Using a students’ workshop as a laboratory, this article summarises the observation of three years’ implementation of a new study module for a Bachelor Program in Engineering Design (Interior and Furniture Design) at the University of Forestry, Sofia, Bulgaria. The article offers an analysis of group dynamics and the difficulties and issues observed during the process. Data from survey questionnaires are interpreted; proposals are made for future research. The conclusion of the authors includes the following points: positive response by students, important encounter with successful professionals and companies; creative fulfilment and experience of team work. On the weak side is the experienced discomfort in public presentation, lack of verbal and graphic skills, interpersonal issues and pressure of real requirements from teachers and company; lack of adequate attention by the tutors. The need of better understanding a team ‘code’ of behaviour and preparation for an active learning method was felt. A proposal leading to a mixed-team organisation for better support of first-time participants in the module is made.  相似文献   

Undergraduates’ implementations of learning stations as their service learning among elementary school students     

Chin-Wen Chien 《Education 3-13》2017,45(2):209-226

Service learning provides pre-service educators with a context for having hands-on field experience and also assists in understanding the theory and practice. This study discusses 7 undergraduates' implementations of learning stations as their service learning with 28 elementary school students. Through thematic data analysis of interviews, observation field notes, activity designs, and discussion posts, this study presented the following major findings. First, elementary school students, seven undergraduates, and a cooperative elementary school English teacher held positive attitudes towards the implementation of learning stations, because these developed children's cooperation and word recognition skills. Second, undergraduates and cooperative teachers gained professionalism through reflection and cooperation, in terms of activity designs, classroom management, and interpersonal skills development with kids and adults. Five suggestions are provided in order to effectively implement undergraduates' activity designs for learning stations as their service learning among elementary school students.  相似文献   

Establishing a ‘Centre for Engineering Experimentation and Design Simulation’: a step towards restructuring engineering education in India     

P. Venkateswarlu 《European Journal of Engineering Education》2017,42(4):349-367

Reforms in undergraduate engineering curriculum to produce engineers with entrepreneurial skills should address real-world problems relevant to industry and society with active industry support. Technology-assisted, hands-on projects involving experimentation, design simulation and prototyping will transform graduates into professionals with necessary skills to create and advance knowledge that meets global standards. To achieve this goal, this paper proposes establishing a central facility, ‘Centre for Engineering Experimentation and Design Simulation’ (CEEDS) in autonomous engineering colleges in India. The centre will be equipped with the most recent technology resources and computational facilities where students execute novel interdisciplinary product-oriented projects benefiting both industry and society. Students undertake two projects: a short-term project aimed at an engineering solution to a problem in energy, health and environment and the other a major industry-supported project devoted to a product that enhances innovation and creativity. The paper presents the current status, the theoretical and pedagogical foundation for the centre's relevance, an activity plan and its implementation in the centre for product-based learning with illustrative examples.  相似文献   

Teacher Stress Related to Student Mental Health Promotion: the Match Between Perceived Demands and Competence to Help Students with Mental Health Problems     

Stine Ekornes 《Scandinavian Journal of Educational Research》2017,61(3):333-353

The present study highlights teacher stress related to student mental health promotion through the relationship between perceived competence, perceived responsibility and negative emotions. Data were derived from a mixed methods design, utilizing three focus group interviews (n = 15), followed by survey research (n = 771) amongst Norwegian K–12 teachers. The results suggest that teacher stress emerges chiefly from a mismatch between feeling responsible for and being able to help students with mental health problems. The data also point to the impact of time constraints in school context. Finally, the findings reveal significantly higher levels of perceived responsibility and negative emotions amongst female teachers, and significantly lower levels of perceived responsibility amongst teachers at higher grades.  相似文献
