Contract cheating is the process whereby students auction off the opportunity for others to complete assignments for them. It is an apparently widespread yet under-researched problem. One suggested strategy to prevent contract cheating is to shorten the turnaround time between the release of assignment details and the submission date, thus making it difficult for students to make arrangements with contractors. Here, we outline some characteristics of the current market for contract cheating and demonstrate that short turnaround times are unlikely to prevent contract cheating because requested turnaround times for university-level assignments completed via contract cheating are already short (average 5?days). In addition, for every contractor awarded a job, there are an average of 10 others offering to complete it within the specified time suggesting that there is abundant excess capacity in the market.  相似文献

Collaboration practices vary greatly per scientific area and discipline and influence the scientific performance and its scholarly communication. In this study, the collaborative pattern of the Information Retrieval (IR) research field is analyzed using co-authored articles retrieved from Social Science Citation Index for a period of 11 years from 1987 to 1997. The level of collaboration, journal collaborative distribution, disciplinary collaborative distribution and country collaboration are probed according to IR collaborative research. Findings are discussed from the above perspectives in detail. In particular, this study reveals a perceptible upward trend of collaborative IR research with the results of these research efforts being reported in all major core IR journals. The inter-disciplinary and intra-disciplinary scholarly communications in collaborative researches are very much in evidence and cover broad areas like psychology, and computer and medical sciences, respectively.  相似文献

Critical thinking skills are required to successfully navigate the overwhelming amount of information sources available today. To address the challenge of developing critical thinking skills, this empirical study examines the effectiveness of exercises in developing thinking skills in college freshmen students. The workbook exercises were designed to develop specific skills related to academics and critical thinking. Two groups of college freshmen participated in the study: one group was given the workbook, the other group was not. At the end of the semester, both groups completed a critical thinking assessment test. A comparison of the test scores confirms the effectiveness of these exercises on improving the critical thinking skills of college freshmen.  相似文献

The fundamental purpose of higher education is to expose the student to the theories, processes and literature of one or more fields of study. However, there is no doubt that thorough training in the applied aspects of that field will be of great help both to the student and the industry he plans to join. A thorough knowledge of broadcasting as an art, a business, and a profession should fit the student both for obtaining his first position and rising up the ladder with greater ease than someone without such training. Without slighting in any way the academic study of broadcasting, it is evident that any methods for obtaining practical experience to complement and supplement the classroom are worth consideration.  相似文献

This article adds to the recent literature that questions, and hopes to redefine, the information literacy notions and practices in academic libraries and their institutions. The authors draw on research in the area of social justice to express the need for academic libraries to explore new avenues to insure their institution's graduates are not merely competent consumers of information. The authors put forward the notion of the intentional informationist, who they define as having the contextual, reflective and informational skills to identify information opportunities, tackle complex information problems and pitfalls, and provide solutions or considerations that do not just meet her individual needs. In addition, they pose questions and detail opportunities, partnerships, and examples of curricular and co-curricular integration to engage students beyond the library, instruction sessions, a single course, or graduation requirement.  相似文献

This paper explores ways in which student‐teachers in the Lifelong Learning sector are able to draw on fictionalised accounts of their own teaching practice experiences in order to gain a clearer understanding of their models and expectations of professionalism, and of how they, as individuals, locate their current position within the profession as a community of practice. It argues that the translation of experience into fiction – in this case specifically in the form of fairy tales – can be usefully applied in order to enhance and encourage reflection on practice as part of an action research cycle. Drawing on the evidence gathered, the paper goes on to suggest that student teachers’ main preoccupation at this stage of their development is not so much with meeting ‘standards’ of professionalism as with questions of behaviours and practices that will lead to a sense of belonging and acceptance; and with the need to transform their status, in relation to the profession, from that of outsider to insider.  相似文献

It is asserted that the mass media play a significant part in the education policy process, yet this contribution has received little attention in empirical and theoretical analyses. Convergence between theoretical work on education policy and media studies in linking social institutions with the economy in the perpetuation of social inequalities, while accepting their relative autonomy, provides a starting point for incorporation of the media role in conceptualization of the education policy process. Concepts which may assist the exploration of the media role within education policy are denned, including the anthropological notion of myths. These concepts are employed in analysing a policy issue wherein the British government and the mass media framed the relevant debate as a polarization between progressive and traditional education. The analysis draws on the experience of a primary school which was portrayed in a current affairs television programme as exemplifying progressive educational practices. Topics that would benefit from further study are suggested.  相似文献

Sixth grade students were compared by sex for their performance on two perspective coordination tasks. Responses were compared with understanding of the principle that still water remains invariantly horizontal. Forty-eight randomly selected sixth grade students (24 girls and 24 boys) and 12 college women were individually shown a standardized three-dimensional scene. While seated in a single position, subjects completed two tasks: (1) selecting from a set of 12 pictures (displayed together) the one which could be seen from each of eight positions marked on the displayed scene and (2) choosing the positions from which could be seen eight of the 12 pictures (shown one at a time). Four of the 12 pictures were mirror images which were impossible views. Males outperformed females on both of the coordination-of-perspective tasks. For both males and females, choosing the place was more difficult than choosing the picture. Strong relationships were found between understanding of horizontality and performance on the perspective tasks. Selection of mirror images (impossible views) indicated more understanding of perspective than other, less systematic errors. Finally, female teacher trainees performed only marginally better than sixth grade students, suggesting possible remediation needs.  相似文献

A report is given of the investigation of the iodine content of oyster shells taken from the reefs found in the Gulf of Mexico. The pulverized shells as sold on the market contain 200 to 300 parts per billion of iodine. Water soluble and alcohol soluble iodides appear to be absent. The granulated undried shells contain 500 parts per billion of iodine. Apparently there is a loss of iodine due to the temperature at which the pulverized shells are dried.  相似文献
