The cognitive processes used by children during problem solving have received considerable attention in recent years. The identification of the processes used by both successful and unsuccessful problem solvers has been hampered by the difficulties involved in making accurate observations of mental processes which may or may not have physical manifestations during problem solving. In addition, problem solvers themselves often are unaware of many of the thought processes they use while attempting to solve problems. The most popularly used methods for studying problem solving processes are not sufficiently reliable or valid. This study explored the potential effectiveness of a new procedure for identifying and studying certain of the cognitive processes used during problem solving. In addition, the procedure was used to categorize the types of conceptual thinking problem solvers employ, to study the use of trial and error behavior, and to investigate problem solvers’ abilities to coordinate multiple bits of information. It appears that the procedure has application for generating hypotheses about cognitive processes problem solvers use.  相似文献

While dissection remains the method of choice for teaching human anatomy, ethical requirements for obtaining cadavers has made the process of acquiring human bodies more strenuous for institutions. In Africa and at the School of Anatomical Sciences in South Africa, dependence on unclaimed bodies has been prevalent. The aim of the present study was to determine whether more rigorous application of ethical consent has altered the provenance of the cadavers in the School of Anatomical Sciences, University of the Witwatersrand. The numbers of bequeathed/donated/unclaimed cadavers received over the period 2013–2017, as well as their sex and population affinity were analyzed. The majority (96.8%) of the cadavers dissected over the period were from bequests/donations. Marginally more females than males were available. In addition, the population affinity of the cadavers had changed from a majority of South African African (unclaimed) bodies to a majority of South African White (bequest/donated) bodies. The study shows that even with ethical constraints it is possible to transition from the use of mainly unclaimed bodies to the acquisition of bequeathed/donor bodies. However, there may be challenges in relation to anatomical collections in the School as few of the bequest/donated cadavers remain in the School to be added to the collections. These changes also affect the demographics of the Schools' collections.  相似文献

This pilot study examined working conditions reported by special education teachers of students with emotional and behavioral disorders (EBD) to identify factors common to teachers likely to leave their positions within the next 2 years and factors common to those likely to stay. Survey responses from an international sample of 776 teachers and related services providers indicated administrative support, availability of support personnel, access to curricula, adequate time for paperwork, years of teaching students with EBD, and behavior management approach used are significantly related to participants' intent to stay or leave. Physical injury by a student was among factors reported as not significant. This study is discussed in terms of its implications for addressing the current shortage of EBD teachers. © 2009 Wiley Periodicals, Inc.  相似文献

The aim of this study is to evaluate the capacity of an e-learning tool (blog) to facilitate reflection among students as part of collaborative group learning. The paper provides insights into student attitudes towards blogs as an interactive and reflective learning tool. Additionally, the study highlights the differences between domestic and international student attitudes towards reflection as part of collaborative learning in groups. The results indicate that international students consistently viewed the use of e-learning tools more positively than domestic students. For educators, the results provide direction in terms of enhancements to assessment tasks incorporating e-learning, including the professional development of staff to address the rapidly changing learning environment.  相似文献

The role of Australian academics is undergoing a period of rapid change as the Federal Government attempts to restructure both the higher education system and the economy. With these changes in role comes a need for the continuing professional development of academics. This paper gives details of a study which adopted a competency‐based approach to identify the job requirements, skill‐deficiencies and training needs of one group of Australian academics. This group ‐ staff from the Business faculties of (former) Colleges of Advanced Education ‐ is of particular interest because its members are experiencing uncommonly rapid growth and change. In general, the respondents tended to rate (a) teaching skills as more important than research skills, (b) their own teaching skills as more highly developed than their research competencies, and (c) their desire for training as greatest with respect to several specific research skills. Some potential barriers to the successful implementation of professional development programmes are discussed.  相似文献

Historically, legislature has been utilized to facilitate appropriate use of cadavers in the anatomical sciences. However, cadaver acquisition and use have also been guided by ethically appropriate and morally acceptable principles. Various global and regional frameworks of “ethical practice” guide body donation, including the use of unclaimed bodies by institutions. These frameworks are responsive to, and reciprocal with the various ethical, moral and legal factors that influence the development of body donation programs. This reciprocity supports the notion that anatomists and anatomical societies have a responsibility to advocate for legal reform when required. In this study, two body bequest programs from geopolitically and socially disparate countries are used as cases to contrast existing legal and governance frameworks for body donation and to examine whether anatomists can direct the acquisition of ethically donated cadavers. The study includes an Australian donor program that has exclusively accepted bequests since its inception, and a South African program that has recently transitioned to a bequest system. Elements such as consent by next-of-kin and Inspector of Anatomy, use of unclaimed bodies and ethics committee approval amongst others, are compared. It is acknowledged that legal frameworks for cadaver acquisition generally deliver broad guidance on acceptable utilization of bodies for the anatomical sciences. However, professional discretion is of importance in adapting to societal needs and values. Thus, while anatomists have been able to progress toward more ethical practice than that which is required by the law, they must continue to do so as societal values evolve.  相似文献

One of the most consistent themes evident in the literature dealing with rural education is that of rural disadvantage. Much research and literature indicates that students from rural schools receive an education that is inferior to that of students from larger urban or suburban schools. Of the matrix of factors reported to lead to that disadvantage, geographical isolation and the extent to which it restricts access is reported to result in rural schools not having the same standard of resource allocation as urban schools where access is not a problem. This study addresses the issue of resource availability in rural and urban Australian schools and includes the variables: students' attitudes towards science and mathematics and career aspirations of these students. The analysis includes socioeconomic status and gender of these students and investigates how these variables relate to student achievement. Do students in rural schools have the same educational opportunity as students in urban schools? In this study a multilevel model is used which takes into account the classroom level variance in student achievement as well as individual variance and school level variance.  相似文献
