Managing change ‐ a case study     

Derek Williams 《School Leadership & Management》2013,33(1):123-129

ABSTRACT

This study describes how two reform approaches-the portfolio culture and teacher professionalism-converge in the context of a system-wide programme for the professional development of school leaders. In particular, the study reports on the use of the portfolio to assist principals, deputy principals and heads of subject departments improve their performance and account for their actions. The study found that participants used their portfolios for a range of purposes: as evidence of improvement; as an organiser; as a record of achievement; as a collection of work samples. Leaders' difficulty in adopting the portfolio for professional accountability arose from a number of tensions: between theory and practice; between public and private demands of portfolios; between the practical nature of leaders' work and the reflective nature of the portfolio; between the portfolio as product and as process; between choice and compliance. It is argued that the use of the portfolio as an accountability vehicle will depend on leaders' capacity to balance these competing demands. The study shows that, despite cultural and logistical problems, the portfolio has the potential to develop the professional knowledge and practice of school leaders.  相似文献

PIE-J [Presentation and Identification of E-Journals] is a set of developing National Information Standards Organization–recommended practices that tries to resolve some of the “pain points” associated with electronic journals. Regina Reynolds, at the Mississippi State University Libraries eResource & Emerging Technologies Summit in August 2012, presented these pain points and the attempts of PIE-J to overcome the obstacles.  相似文献   

'Greyish Rectangles': Creating the television heritage     

Derek Kompare 《Media History》2013,19(2):153-169

In the early months of 1947, as it sought to save power during an acute fuel crisis, Clement Attlee's Labour government suspended the publication of all British periodicals for a period of two weeks. This would have been a bold step for any government, let alone one which had as uncomfortable a relationship with the press as Attlee's did, and, at the time, the press was not slow to suggest that the suspension was motivated as much by political factors as it was by a desire to conserve fuel. This article examines the implementation and nature of the suspension, exploring the tensions it generated and asking whether the government's actions can be described—as they were by some contemporary observers—as a deliberate act of suppression.  相似文献

This study reports an investigation designed to determine the generalizability of source credibility scales for immediate superiors across organizational contexts. Four meaningful and statistically independent dimensions for the measurement of the source credibility of immediate superiors in an organizational setting are reported.  相似文献

Effects of manipulating relative and absolute motion information during observational learning of an aiming task

In the visual perception perspective of observational learning, the manipulation of relative and absolute motion information in visual demonstrations optimally directs learners’ search towards appropriate task solutions. We assessed the effect of emphasizing transformational information and removal of structural information using point-light kinematic displays in approximating the model’s relative motion patterns. Participants viewed computer-simulated point-light demonstrations or normal video demonstrations before and intermittently throughout 100 acquisition trials with knowledge of results on an underarm modified-dart aiming task. On the next day, all participants performed 20 retention trials without demonstrations. The kinematics of spatial and temporal coordination and control variables were examined relative to the model’s action, as well as performance scores. The results indicated that approximation of the model’s spatial and temporal coordination and control patterns was achieved after observation of either type of demonstrations. No differences were found in movement outcomes. In a second experiment, the effects of manipulating absolute motion information by slowmotion demonstrations were examined relative to real-time demonstrations. Real-time demonstrations led to a closer approximation to the model’s spatial and temporal coordination patterns and better outcome scores, contradicting predictions that slow-motion displays convey intact relative motion information. We speculate that the effect of visual demonstration speed on action perception and reproduction is a function of task constraints ‐ that is, novelty or familiarity of relative motion of demonstrated activities.  相似文献

Using Explanatory Item Response Models to Analyze Group Differences in Science Achievement     

Derek C. Briggs 《教育实用测度》2013,26(2):89-118

Correlational evidence suggests that high school GPA is better than admission test scores in predicting first-year college GPA, although test scores have incremental predictive validity. The usefulness of a selection variable in making admission decisions depends in part on its predictive validity, but also on institutions’ selectivity and definition of success. Analyses of data from 192 institutions suggest that high school GPA is more useful than admission test scores in situations involving low selectivity in admissions and minimal to average academic performance in college. In contrast, test scores are more useful than high school GPA in situations involving high selectivity and high academic performance. In nearly all contexts, test scores have incremental usefulness beyond high school GPA. Moreover, high school GPA by test score interactions are important in predicting academic success.  相似文献   

Developing a Scale to Measure Students’ Attitudes toward Chemistry Lessons     

Derek Cheung 《International Journal of Science Education》2013,35(16):2185-2203

Students’ attitudes toward chemistry lessons in school are important dependent variables in curriculum evaluation. Although a variety of instruments have been developed by researchers to evaluate student attitudes, they are plagued with problems such as the lack of theoretical rationale and of empirical evidence to support the construct validity of data. This paper describes a study of students’ attitudes toward chemistry lessons in Hong Kong secondary schools. One of the scales in the Test of Science‐Related Attitudes developed by Fraser was modified to form an Attitude Toward Chemistry Lessons Scale (ATCLS). The construction of the ATCLS was based on a theoretical model with four dimensions: liking for chemistry theory lessons, liking for chemistry laboratory work, evaluative beliefs about school chemistry, and behavioural tendencies to learn chemistry. The arguments for inclusion of these four dimensions are presented. The final version of ATCLS was administered to 954 students. The results of confirmatory factor analysis indicated that there was a good fit between the hypothesised model and the observed data.  相似文献
