Teaching the design and interpretation of graphs through computer-aided graphical data analysis     

David F. Jackson  Billie Jean Edwards  Carl F. Berger 《科学教学研究杂志》1993,30(5):483-501

Graphs are one of the primary means of exploration and communication in the practice of science, but students in science laboratories are customarily taught only the low-level mechanics of constructing a single kind of graph when given a table of information. The use of a microcomputer can relieve the drudgery of plotting, allowing students to pursue higher-level issues in the design and interpretation of graphs through repeated “thought experiments.” We introduced computer-assisted graphical data analysis to inner-city high school students with weak math and science backgrounds, emphasizing the dynamic manipulation of various kinds of graphs to answer specific questions. Drawing on extensive recordings and classroom observations, we describe examples of the performance of these students on open-ended problem-solving tasks in which graphs can be used to arrive at meaningful answers to applied data analysis problems.  相似文献

Consistently inconsistent: An examination of the variability in the identification of emotional disturbance     

Kristin Scardamalia  Keisha L. Bentley‐Edwards  Kairys Grasty 《Psychology in the schools》2019,56(4):569-581

The federal definition of emotional disturbance (ED) has been heavily criticized as vaguely defined and poorly operationalized yet there has not been a formal analysis of the reliability of the ED criteria. This study examined the reliability of the federal criteria for a special education designation of ED. A total of 179 school psychologists reviewed a mock special education report, made an eligibility determination, and provided information about their eligibility decision. In all, 56 participants found the student met ED eligibility criteria using 16 different combinations of the five criteria. Krippendorff’s α, a statistic preferred for content analysis, was calculated as a measure of criterion reliability. Results indicated extremely poor reliability (α = 0.2011). These findings demonstrate the importance of redefining the existing criteria.  相似文献

What stories do I tell now? New times and new narratives for the adult educator     

Richard Edwards  Robin Usher 《International Journal of Lifelong Education》2013,32(3):216-229

Globally, the world of adult education has been much transformed in recent years. While there has been an expansion in the provision made available to adults, the profile of that provision has shifted with a greater emphasis placed on work‐related and certificated education and training, and an increased diversity in learning settings. This has led to a sense of crisis over the meaning of adult education as a specific form of provision and what it means to be an adult educator.

This article examines the ways in which these changes have found expression in the narratives through which adult educators construct their practices and experiences as meaningful. We argue that there is an interaction between the impact of contestation and change in the field of adult education and learning, its narrative or story‐telling practices and the processes by which the identities of adult educators are formed. We examine the significance of this interaction by drawing on three inter‐related themes‐‐the so‐called turn to textuality, the changes taking place in the economy and the organisation of work including the work of adult educators, and contemporary debates over (post) modern identities. In this way, we demonstrate the significance of new theoretical perspectives in providing insights into the contemporary condition of adult educators.  相似文献   

Flexibility,reflexivity and reflection in the contemporary workplace     

Richard Edwards 《International Journal of Lifelong Education》2013,32(6):377-388

Within contemporary changes there is an increased reflexivity wherein social formations, organizations and individuals are required to change, to learn to change, and change to learn. Lifelong learning has become central to education and economic policy, with an increased emphasis on individuals, workplaces and providers of learning opportunities becoming more flexible. This article explores some of the evidence for the emergence of different workplace practices and identities in response to and as part of the development of reflexive modernization and the significance of pedagogies of reflection in these changes. It suggests that pedagogies of reflection are integral to reflexive modernization, flexible lifelong learners and changes in the workplace.  相似文献

The stress of travel     

Waterhouse J  Reilly T  Edwards B 《Journal of sports sciences》2004,22(10):946-65; discussion 965-6

International travel is an essential part of the life of elite athletes, both for competition and training. It is also becoming increasingly common among recreational sportspersons. Long-distance travel is associated with a group of transient negative effects, collectively referred to as 'travel fatigue', which result from anxiety about the journey, the change to an individual's daily routine, and dehydration due to time spent in the dry air of the aircraft cabin. Travel fatigue lasts for only a day or so, but for those who fly across several time zones, there are also the longer-lasting difficulties associated with 'jet lag'. The problems of jet lag can last for over a week if the flight crosses 10 time zones or more, and they can reduce performance and the motivation to train effectively. Knowledge of the properties of the body clock enables the cause of the difficulties to be understood (an unadjusted body clock), and forms the basis of using light in the new time zone to promote adjustment of the body clock. Sleep loss and its effects are important components of jet lag, and attempts to promote sleep by the use of melatonin and other hypnotics are also relevant. Sleep loss is also found in those who undertake challenges that involve long periods where the normal consolidated sleep of 8 h length is not possible. Advice on sleep regimens in such circumstances is given.  相似文献
