美国大学系主任管理和领导角色探析

在美国,系是大学最基本的组成单位。因此,大学系主任几乎负责与教、学、研及向社会提供服务有关的各项活动,通常扮演管理和领导的双重角色。其主要的工作包括开发师资、组织管理本系的各项日常活动和事务、领导本系的整体发展以及从事教学科研工作。显而易见,美国高等教育能够达到今天的水准与系主任的贡献是分不开的。中国高校正在面临、或在不同程度上进行内部结构和职能的调整和重组。尤其是许多大学纷纷成立学院。因而,对系主任管理领导角色进行重新定位具有深远意义。相信了解和借鉴国外的成功经验定有裨益。     

Reasoning about structure and function: Children's conceptions of gears

Twenty-three second graders and 20 fifth graders were interviewed about how gears move on a gearboard and work in commonplace machines. Questions focused on transmission of motion; direction, plane, and speed of turning; and mechanical advantage. Several children believed that meshed gears turn in the same direction and at the same speed. Many second graders provided very incomplete explanations of transmission of motion. Most children confused mechanical advantage with speed. Yet as the interview proceeded, several fifth graders generalized conceptions about transmission of motion into a rule about turning direction. They increasingly justified their ideas about gear speed by referring to ratio. Children's reasoning became more general, formal, and mathematical as problem complexity increased, suggesting that mathematical forms of reasoning may develop when they provide a clear advantage over simple causal generalizations. © 1998 John Wiley & Sons, Inc.

FURTHER EVIDENCE ON THE EFFECT OF DATE OF BIRTH ON SUBSEQUENT SCHOOL PERFORMANCE

In a previous paper (Hartley and Holt, 1971) the development of a three‐minute reasoning test was described, and its validity and reliability assessed. In this paper three experiments are reported which look in greater detail at these aspects of the test in different situations. The results of the experiments indicated that the test was less valid and was less reliable than was originally anticipated.     

Is a higher rate of R&D tax credit a panacea for low levels of R&D in disadvantaged regions?

This paper studies the impact of R&D spending on output as well as forecasting the impact of a regionally enhanced R&D tax credit on the ‘user cost’ (or price) of R&D expenditure and subsequently the demand for R&D. The example we use of a ‘disadvantaged’ region is Northern Ireland (partly because it has the lowest levels of R&D spending in the UK, and partly because the necessary data is available for this region). We find that in the long run, R&D spending has a mostly positive impact on output across various manufacturing industries. In addition, plants with a zero R&D stock experience significant one-off negative productivity effects. As to the adjustment of R&D in response to changes in the ‘user cost’, our results suggest a rather slow adjustment over time, and a long-run own-price elasticity of around −1.4 for Northern Ireland. We also find that to have a major impact on R&D spending in the Province, the R&D tax credit would need to be increased substantially; this would be expensive in terms of the net exchequer cost.     

A Critical Review of Line Graphs in Behavior Analytic Journals

Visual displays such as graphs have played an instrumental role in psychology. One discipline relies almost exclusively on graphs in both applied and basic settings, behavior analysis. The most common graphic used in behavior analysis falls under the category of time series. The line graph represents the most frequently used display for visual analysis and subsequent interpretation and communication of experimental findings. Behavior analysis, like the rest of psychology, has opted to use non-standard line graphs. Therefore, the degree to which graphical quality occurs remains unknown. The current article surveys the essential structure and quality features of line graphs in behavioral journals. Four thousand three hundred and thirteen graphs from 11 journals served as the sample. Results of the survey indicate a high degree of deviation from standards of graph construction and proper labeling. A discussion of the problems associated with graphing errors, future directions for graphing in the field of behavior analysis, and the need for standards adopted for line graphs follows.     

University Admissions and the Prediction of Degree Performance: an Analysis in the Light of Changes to the English Schools’ Examination System

The United Kingdom's Department for Education has recently changed the nature of the AS‐level examinations normally taken by students aspiring to enter higher education degree courses one year into their post‐compulsory education. In the face of protests from universities and other institutions that this would both harm students’ progression towards the A‐level qualifications, on which entry to English universities is normally based, and make it difficult for universities determining which of their applicants were best placed to benefit from their degree courses, the Department conducted research which it claimed showed that degree outcome could be predicted as well from the results of GCSE examinations taken one year before AS‐levels as from AS‐levels themselves. This paper critiques those analyses and their conclusions showing, through a re‐analysis and extended interpretation of the Department's data, that AS‐levels provide a more reliable predictor of degree performance in 2011 than GCSEs and that many students who performed better at AS‐level than at GCSE gained a place, and performed well, at a university with high entrance standards.

Commentary on research into learning in physical education: towards a mature field of knowledge

In this commentary, I consider each of the papers in this special issue in regard to their contribution to a debate on the nature of learning in physical education (PE). I also discuss how we might take this aspiration further by moving beyond a ‘mere’ debate over learning theories to a knowledge building process in which knowledge claims are ‘tested’ against their compatibility (or non-compatibility) with other ‘knowings’. In this regard, I introduce the idea of vertical integration or compatibility as a consideration for building a more mature field of study of learning in PE.     

U3As in Australia and New Zealand: their value to the wider community,and new directions for future developments

Population ageing and growing competition for limited resources are likely to increase the onus on older adults to maximize their own well‐being. Recent literature speculates that it may be possible for older people to improve, or at least maintain, aspects of their health by engaging in stimulating mental activity. If that is the case, self‐funding adult education organizations like the University of the Third Age (U3A) are contributing, not only to the well‐being of members, but also to the national economy. U3A has grown strongly in Australia and New Zealand in recent years, and the value of its voluntary services to the community is calculated to be more than A$3 million annually. Despite their present rapid growth, the independent U3A groups may need to develop a more outward‐looking focus if they are to continue to meet the needs of existing members, and to provide different kinds of intellectually challenging programmes for newer ageing cohorts. One practical way of doing this would be through electronic networking between the U3A groups and similar adult education organizations, as well as by using the limitless resources on the World Wide Web. However, the hardware for electronic communication is expensive and purchases of this nature would be beyond the immediate resources of most U3A groups. A mechanism is outlined by which U3As may be able to attract one‐off funding for the purchase of computers or other resources which could help them to meet their educational objectives.
