The peer rating system used here advances the quantitative literacy goals outlined in the social sciences. We instituted a mid-semester intervention to teach rating skills and used an index to track longitudinal changes of skill mastery over the course of the semester. Seventy-four students in five advanced research classes followed the procedure of the existing peer rating system by completing reading assignments, writing reflections online, engaging in class discussions, rating their peers’ reflections and receiving feedback on their group effort. Peer ratings were then compared with each other and also with the instructor ratings to derive individualised indices of reliability and validity. These technical indicators enabled two rounds of assessment before and after a class-wide intervention. An omnibus test across the five classes showed a significant improvement in rating quality due to the intervention. Our courses not only met a quantitative learning outcome but also promised vocational competence.  相似文献

The importance of the laboratories for the study of engineering problems is manifold. At the undergraduate level it provides an opportunity for the students to get an impression of the basic principles of engineering. At the postgraduate level it becomes an instrument for advanced level study and for the solutions to real-life engineering problems. Level of emphasis by an individual engineering institution on basic engineering, interdisciplinary aspects of engineering and relevance to international, national and local industrial trends effects the policy to establish the engineering laboratories. However, a core facility, for the teaching of the most basic principals of relevant field of engineering should be a common feature of all the laboratories associated with individual subject area. In this research paper an approach for establishing engineering laboratories is presented. It discusses the relation between the syllabus of appropriate level of study and the equipment required in the laboratory, physical planning for the laboratory, sequential and parallel approaches for establishing the laboratories, the functional capacity of laboratories, the organizational flexibility of the laboratories, the cost factor and the recurring expenditure. It suggests ways of utilizing the laboratory for effective teaching and research through optimal use of the above factors.  相似文献

INTRODUCTION Rice (Oryza sativa L.) is one of the most im-portant crops in Pakistan. It is the third largest crop interms of area and production after wheat and cotton.Although rice in Pakistan is consuming large acreage,Pakistan is still far behind other rice producingcountries. The average yield is very low (2 t/ha) ascompared to Egypt (8.4 t/ha) and USA (6.6 t/ha).There are many reasons for this low yield. The mostimportant are high temperature (40?50 °C), low hu-midity at …  相似文献

The article stresses the significance of anti-poverty oriented rural development for developing countries and the need to identify the educational implications of such a strategy. Some of the assumptions derived from contemporary experience in development, and in particular rural development, which are vital for understanding and formulating the role of education, are presented and analysed. The indicators used in the measurement of anti-poverty rural development bring clarity to the concept of interlinking development and education in concrete terms. Some features of education for rural development are discussed and the significance of four areas of educational activities underscored, namely, primary education, functional literacy, human resources development and education related to the world of work. The article is concluded by stressing the need for establishing firm linkages between educational and developmental infrastructures with special emphasis on nonformal education and its flexibility of approach.
Zusammenfassung Der Nachdruck in diesem Artikel liegt auf der Bedeutung, die der armutsbekämpfenden Orientierung ländlicher Entwicklungsprogramme beizumessen ist, sowie auf der Notwendigkeit festzustellen, welche Implikationen sich aus einer solchen Strategie für das Erziehungswesen ergeben. Einige für das Verständnis und die Formulierung seiner Rolle entscheidende Voraussetzungen, abgeleitet aus neueren Erfahrungen mit Entwicklungsprogrammen, insbesondere ländlichen, werden vorgestellt und analysiert. Die für die Bemessung armutsbekämpfender ländlicher Entwicklung benutzten Indikatoren bringen auch Klarheit in das Konzept einer konkreten Verbindung von Entwicklung und Erziehung. Dann bespricht der Autor einige Besonderheiten der Erziehung für ländliche Entwicklung und unterstreicht dabei die Wichtigkeit von vier Gebieten der Erziehungsarbeit: Primarerziehung, funktionelle Alphabetisierung, Entwicklung von Arbeitskräften und auf die Arbeitswelt bezogene Erziehung. Zum Schluß hebt der Verfasser die Notwendigkeit hervor, die Infrastrukturen für Erziehung und Entwicklung fest miteinander zu verbinden, mit besonderer Betonung der nicht-formalen Erziehung und ihrer Flexibilität.

Résumé L'auteur de cet article met en évidence la signification du développement rurale envisagé comme une lutte contre la pauvreté dans les pays en développement et il souligne la nécessité de découvrir les implications de l'éducation dans une telle stratégie. Il présente et analyse quelques-unes des inductions tirées de l'expérience contemporaine du développement, en particulier du développement rurale, indispensables à la compréhension et à la formulation du rôle de l'éducation. Les indicateurs utilisés pour mesurer le développement rural anti-pauvreté apportent aussi une clarté au principe de conjugaison de l'éducation et du développement en termes concrets. Ensuite l'auteur examine quelques traits de l'éducation pour le développement rural, mettant l'accent sur l'importance de quatre zones d'activités éducatives, à voir, l'enseignement primaire, l'alphabétisation fonctionnelle, le développement des ressources humaines et l'éducation reliée au monde du travail. Enfin il souligne la nécessité d'établir des liens solides entre les infrastructures de l'éducation et celles du développement, en accentuant particulièrement l'éducation non-formelle et la flexibilité de ces moyens.

Abstract

Outdoor education is emerging as a compulsory component of the school curriculum in Singapore. As more and more young people are involved in outdoor education programmes, the motivational factors that influence students' participation in outdoor activities is an important area of study. The purpose of this study was to use the self-determination theory framework to examine post course satisfaction level among young adolescents. A total of 314 secondary school students aged from 12 to 16 years took part in the survey. Results showed that external regulation negatively predicted self-reported satisfaction whereas intrinsic motivation positively predicted participants' satisfaction levels of the course. It is highlighted that young adolescents should not be coerced into outdoor education programmes. They should be provided with a meaningful rationale for participation, given some autonomy for decision-making and to have a positive and enjoyable experience during the programme.  相似文献

This article explores the need for public and school library cooperation in Sierra Leone. Establishing a library service to meet user needs and keeping it relevant is one of the important tasks of professional librarians. In Sierra Leone, however, an increase in enrollment in schools, decreasing library budgets, and the information explosion have had grave consequences in the management of libraries, be they special, school, or public. If public and school libraries are to provide satisfactory services to the nation's young, there is every need for the establishment of greater public and school library cooperation.  相似文献

This study reviews the higher education movement, and the development of Universities in Jordan. Academic libraries use of Arabized software packages (MINISIS and CDS/ISIS), rationale for selection, applications, services, problems, solutions, and future plans are surveyed. Types of hardware, staff, and material entries are discussed. The study samples included 20 libraries. All of 17 (85%) respondent libraries are computerized. Six (35·3%) use MINISIS, nine (52·9%) use CDS/ISIS, and two (11·8%) use customized packages. Systems are mostly employed in technical processing, reference services, bibliographies, and acquisitions. Adaptability to Arab libraries functions, handling of bi-lingual documents, and networking ability are the prime priority, inter alia , reasons for packages selection. Insufficient funds and equipment, and unskilled staff are the major hindrances which obstruct the full use of packages. This study stresses the need to develop packages conducive to meet particular Arab libraries demands, plans for manpower academic training, and the necessity for libraries linkage to networks.  相似文献

The present study aims to assess and compare the biochemical oxidative stress markers in male smokers and non-smokers with chronic periodontitis. One hundred thirty-four male chronic periodontitis patients and 64 apparently healthy male volunteers were recruited for the study. The periodontal status was evaluated by measuring gingival index, plaque index, papillary bleeding index and clinical attachment loss using UNC-15 probe. The biochemical markers estimated were total antioxidant capacity, RBC-superoxide dismutase, glutathione peroxidase, vitamin C, malondialdehyde and C-reactive protein. The obtained results indicate higher oxidative stress in chronic periodontitis. Smokers with chronic periodontitis show significantly higher periodontal clinical parameters and relatively higher systemic oxidative stress. Vitamin C estimation may be an important biochemical parameter in conjunction with clinical parameters for diagnosis of chronic periodontitis in smokers.  相似文献
