复杂系统视角下的组织学习动态过程研究

组织是一个具有无尺度网络结构的复杂系统。组织学习作为组织获取核心竞争力和可持续发展能力的重要手段,是一个动态的过程:从组织学习发生的载体来看,主要有个人、团队和组织等三个层次;就组织学习发生的方式来看,包括单环学习、双环学习和三环学习等三种模式;而从组织学习过程本身来看,则分为直觉感知、解释说明、归纳整合和制度化等四个子过程。本文在系统回顾相关研究成果的基础上,从复杂系统的角度对组织学习过程进行了系统的模型整合和创新,对复杂系统环境下如何构建学习型组织的可能遇到的障碍进行了一系列的分析。     

The Heuristic for Thinking About Culturally Responsive Teaching (HiTCRiT)

Michèle was hurrying to class. How, she thought, could she offer the students in her African American English in Society and Schools class a method of understanding, comparing, and abstracting the studies they had been reading in class? The heuristic described in this study evolved from a desire to capture aspects of several seminal studies that illustrated how African American English was deployed in classrooms for productive work with African American students. Michèle recalled that whenever she asked graduate students or practicing teachers what they, other teachers, and schools might do to improve the schooling of students of color, one of the most consistent responses was Culturally Responsive Pedagogy (CRP). However, when pressed and asked what one would detect in classrooms where CRP is being put into practice, few were able to specify what an observer might see. Specifying the dimensions of CRP and its relationship to the heuristic had not been on Michèle’s mind. Even so, it was during the class discussion that the heuristic’s relevance to CRP became clearer. Jonathan, who had been tapped as a teaching assistant in an English language arts methods class, believed HiTCRiT could be modified to use with teacher education candidates, as a substitute for the standardized lesson planning tool used in the department. He piloted its use with the class the following semester. Utilizing HiTCRiT to explain research and existing practices as well as to assist teachers in creating culturally relevant instruction modified and shaped it, creating a more robust tool. Thus, the HiTCRiT came into being and came to inform our thinking and teaching practice.     

Characterising the impact performance of field hockey sticks

Published research on field hockey equipment is scarce. The aim of this research was to investigate methods for characterising the impact performance of field hockey sticks. Three sticks were used with fundamental frequencies in the range 74?C154?Hz. Striking an initially still ball with a stick was identified as the preferred method for characterising performance. Impacts were simulated at mean velocities of 19?m/s at toe and 16?m/s at the shaft. The mean apparent coefficient of restitution and standard deviation were ?0.32?±?0.05 at the toe and ?0.18?±?0.02 at the shaft. The foundation work presented here provides the foundations for developing a methodology for characterising the impact performance of field hockey sticks.     

Teacher effects on student attrition and performance in mass-market tertiary education

Tertiary education is now accessible even to those who appear unlikely ex ante to succeed in jobs requiring post-high school education. Institutions that have broadened access to their programs must rely on two things to protect the quality of the degrees they award: selection mechanisms operating during students’ tenure, and effective teaching. This paper explores the relative strength of these two forces in a broad-spectrum, first-year undergraduate course. Using detailed data from the University of South Australia on student background, tutors, performance, and enrollment across 15 weeks in a first-year core course, I explore the extent to which teachers impact upon the success of their students directly (through effective teaching) and indirectly (through facilitating the dropping out of more poorly-prepared students). Results indicate that teachers vary widely in their influence on attrition and performance, and that none is robustly effective in facilitating both the disproportionate out-selection of students with poor initial preparation, and the disproportionate achievement of this group. Performance at neither of these tasks is predictable based on teachers’ formal university affiliation.     

Library development and the joint commission on accreditation of hospitals standards.

The author traces the historical development of standards for library services prepared by the Joint Commission on Accreditation of Hospitals, emphasizing those elements of the present standards that auger well for the development of libraries in hospitals. Then examined are the role of librarians and new roles for libraries, stressing sound management practices that ensure continued development.     

Doing a science project: Gender differences during childhood

By adolescence, men's participation and achievement in science exceeds women's. This article reports a case study that examined the beginnings of this gender differentiation during a naturally occurring academic activity that was designed to support and guide young children's interest in doing science. Data were collected during 2 successive years of a science fair for children in Grades 1–6 of a progressive private school. A total of 268 projects were characterized in terms of achievement and area of science. Parents provided information about the way children selected and created projects. In both years and in all grade levels, boys tended to choose to work in the physical sciences, and girls in the biological and social sciences. Peer collaborations were exclusively same sex. Achievement and parental involvement were not gender related. Factors are discussed that might lead to an early divergence of boys' and girls' interests in science within a context that promotes its exploration. © 1998 John Wiley & Sons, Inc.

Factors associated with physical activity referral uptake and participation

The aim of this study was to examine participant and scheme characteristics in relation to access, uptake, and participation in a physical activity referral scheme (PARS) using a prospective population-based longitudinal design. Participants (n = 3762) were recruited over a 3-year period. Logistic regression analyses identified the factors associated with the outcomes of referral uptake, participation, and completion (> or = 80% attendance). Participant's age, sex, referral reason, referring health professional, and type of leisure provider were the independent variables. Based on binary logistic regression analysis (n = 2631), only primary referral reason was associated with the PARS coordinator making contact with the participants. In addition to the influence of referral reason, females were also more likely (odds ratio 1.250, 95% confidence interval 1.003-1.559, P = 0.047) to agree to be assigned to a leisure provider. Referral reason and referring health professional were associated with taking up a referral opportunity. Older participants (1.016, 1.010-1.023, P < 0.001) and males were more likely to complete the referral. In conclusion, the PARS format may be less appropriate for those more constrained by time (women, young adults) and those with certain referral reasons (overweight/obesity, mental health conditions). More appropriate targeting at the point of referral could improve participation rates by revealing or addressing barriers that might later result in dropout.     

Teaching in the Yukon: Exploring teachers’ efficacy beliefs,stress, and job satisfaction in a remote setting

This article presents a mixed methods examination of teachers’ job beliefs in the Yukon Territory in northern Canada. In Study 1 we used questionnaires to examine job beliefs for 221 teachers from the Yukon and western Canada. Teachers’ self- and collective efficacy and workload stress were lower for Yukon teachers, but levels of overall stress and satisfaction were similar across settings. In Study 2 we conducted interviews to examine how geographical, community, and cultural factors were related to Yukon teachers’ job beliefs. Results showed that job stress and job satisfaction were influenced by physical and human geography, level of connection with the community, and by the community's cultural transitions. The findings highlight the influence of cultural and community factors on teachers’ working lives.     

Developing mathematical fluency: comparing exercises and rich tasks

Achieving fluency in important mathematical procedures is fundamental to students’ mathematical development. The usual way to develop procedural fluency is to practise repetitive exercises, but is this the only effective way? This paper reports three quasi-experimental studies carried out in a total of 11 secondary schools involving altogether 528 students aged 12–15. In each study, parallel classes were taught the same mathematical procedure before one class undertook traditional exercises while the other worked on a “mathematical etude” (Foster International Journal of Mathematical Education in Science and Technology, 44(5), 765–774, 2013b), designed to be a richer task involving extensive opportunities for practice of the relevant procedure. Bayesian t tests on the gain scores between pre- and post-tests in each study provided evidence of no difference between the two conditions. A Bayesian meta-analysis of the three studies gave a combined Bayes factor of 5.83, constituting “substantial” evidence (Jeffreys, 1961) in favour of the null hypothesis that etudes and exercises were equally effective, relative to the alternative hypothesis that they were not. These data support the conclusion that the mathematical etudes trialled are comparable to traditional exercises in their effects on procedural fluency. This could make etudes a viable alternative to exercises, since they offer the possibility of richer, more creative problem-solving activity, with comparable effectiveness in developing procedural fluency.
