The purpose of this article is to present a specific approach to the practice of action research ‘in complex organisations’. Clearly, there are many approaches to the challenge of doing action research in organisations; approaches that are, and also must be, quite context dependent and specific. But my purpose is neither to give an overview nor a recommendation of how action research is or should be done in complex organisations by different schools of action researchers around the world. The approach I will present has grown through practical experience accumulated over many years with doing action research in many different Norwegian organisations with organisational change and development as the specific objective. I will limit myself to an outline of this Norwegian context, and to how I and others have worked specifically with organisational learning both practically and theoretically within or in relation to a broad Norwegian or Scandinavian approach to action research and organisation development represented by many individuals.  相似文献

There is a strong relationship between orthographic–motor integration related to handwriting and students' ability to produce creative and well‐structured written text. This relationship is thought to be due to the cognitive load which results when attention is required by writers to write letters and words on the page. Lack of automaticity in orthographic–motor integration means that writers do not have sufficient cognitive resources to accomplish the more demanding aspects of text production such as ideation, text monitoring, and pragmatic awareness. A systematic handwriting program can significantly improve the quality of written text by young children experiencing problems with orthographic–motor integration. This study investigated the effectiveness of a handwriting program in remediating older students' problems in orthographic–motor integration and consequently enhancing their written language skills. Two groups of students in Grades 8 and 9 were provided with either practice in handwriting or daily completion of a written journal. There were no differences between the two groups at pre‐test. However, at post‐test, the handwriting group had significantly higher scores in orthographic–motor integration as well as for the length and quality of the text they wrote.  相似文献

The purpose of this study was to investigate three instructional design variables hypothesized to improve rule learning by use of information processing methods. These variables included: analysis and structure of information, response-sensitive sequencing of information, and monitoring of learning time. Using secondary education students learning internal punctuation rules, results from two experiments showed that (a) structuring information by a schematic analysis improved learning over a taxonomic analysis, (b) a response-sensitive sequence that first adapted instruction for generalization and second discrimination improved learning over either sequence separately, and (c) program monitoring of the display time interval improved learning over learner control. Findings are discussed in reference to an interactive nature of learning theory, instructional systems, and computer technology.  相似文献

Abstract

In recent years, a method of plyometrics (exercises that cause a rapid lengthening of a muscle prior to contraction) called depth jumping has become a part of the training routine of many athletes. Two experiments are described in which the effectiveness of the exercises is examined. In Experiment 1, undergraduate students in beginning weight training classes trained with three different jumping programs: (1) maximum vertical jumps, (2) 0.3 m depth jumps, and (3) 0.75 m and 1.10 m depth jumps. In addition, all groups also lifted weights. In Experiment 2, a weight training class and the volleyball team at Brigham Young University-Hawaii were divided into two groups. One group lifted weights and performed 0.75 and 1.10 m depth jumps. The other group only lifted weights. In Experiment 1, the three training programs resulted in increases in one repetition maximum (1 RM) squat strength, isometric knee extension strength, and in vertical jump; however, there were no significant differences between treatments. In Experiment 2, all groups made significant increases in vertical jump, except the group of weight lifters, who did no jumping. It was concluded that depth jumps are effective but not more effective than a regular jumping routine.  相似文献

Since the mid-nineteenth century, student worker programs have been an integral component of academic libraries, and the evolution of the profession has put more students, even undergraduates, into positions with greater responsibility, raising questions about the level of expertise of which undergraduate students are capable. The authors address these questions through the lens of the collaborative redevelopment of two distinct library student worker programs at a small liberal arts college. Included is a discussion of successes and challenges, as well as a consideration of the benefits of a “cross-library” support system in developing such a program.  相似文献

ABSTRACT

The National Institutes of Health (NIH) funds biomedical research and conducts its own research. One way the NIH Library supports this work is by providing librarians with biomedical training and encouraging them to become embedded with researchers and administrators. Some of these “informationists” have degrees in scientific or health fields, and all engage in ongoing training, mostly through coursework at local institutions and at NIH itself. This article elaborates on the training of NIH informationists. Past research has indicated that patrons welcome librarians with biomedical training, which may in turn lead to greater communication between librarians and researchers.  相似文献

In this article the authors present a confirmatory factor analysis of the Teachers’ Attitudes Toward Computers (TAC) and the Teachers’ Attitudes Toward Information Technology (TAT) scales by Christensen and Knezek (1996, 1998) using large samples from three states. The TAC was reduced from 98 items and nine factors to 35 items and eight factors, while maintaining superior psychometric properties. The TAT was reduced from 50 items and five factors to 20 items measuring five factors, similarly maintaining excellent psychometric properties. The authors also developed a combined short form of both instruments using 42 items to measure 11 factors for use in situations where parsimony is critical.  相似文献
