This study explores the level of availability of computers, Internet accessibility and the rate of usage of computers both at home and at the work place between distance education learners according to gender. The results reveal that there are no significant differences in all three aspects. The findings indicate that female distance education learners participate equally with their male counterparts in the utilization of computer technology to assist their study requirements as well as in their involvement in information and communication technology (ICT) to support the educational and learning process as demanded by distance education. Différences de sexe dans la disponibilité, l'accès À internet et la fréquence d'utilisation des ordinateurs chez les étudiants apprenant À distance. Cette étude explore le niveau de disponibilité, l'accès À internet et la fréquence d'utilisation des ordinateurs À la fois au travail et À la maison chez les étudiants apprenant À distance en fonction de leur sexe. Les résultats montrent qu'il n'y a pas de différences significatives dans chacun de ces domaines. Les résultats indique que les femmes participent À égalité avec les hommes dans l'utilisation de l'ordinateur pour les aider À faire face aux exigences de leurs études aussi bon que dans leur implication dans les technologies de l'information et À la communication (TIC) pour soutenir le processus d'éducation et d'apprentissage imposé par l'éducation À distance. Geschlechtsbezogne Unterschiede bei der Verfügbarkeit eines Internetzugangs und Nutzung von Computern bei Studenten des Fernunterrichts. Diese Studie untersucht die geschlechtsbezogne Verfügbarkeit von Computern, Internetzugang und Häufigkeit der Computernutzung daheim und am Arbeitsplatz bei Studenten des Fernunterrichts. Die Resultate zeigen, dass es bei den 3 Aspekten keine grossen Unterschiede gibt. Die Untersuchungen belegen, dass Frauen genau so oft wie ihre männlichen Kollegen die Computertechnologie zu Studienzwecken einsetzen und die Informations- und Kommunikationstechnologie (ITC) für ihren Lernprozess nutzen, so wie es im Fernunterricht verlangt wird.  相似文献

Abstract

Purpose: This article reviews the experience of ICT applications as a tool for putting research derived knowledge into use for innovation in South Asia.

Design/methodology/approach: The article uses the contemporary understanding of communication and innovation in reviewing the experience of ICTs in putting new knowledge into use in South Asia.

Findings: The findings from this study suggest that ICTs in general have not contributed effectively to the challenge of putting new knowledge into use as they are mostly used to support traditional communication tasks — such as information dissemination and training. The article argues that this under-utilisation of the potential of ICTs could be due to: a lack of appreciation of the new communication-intermediation tasks required for innovation, underestimation of the roles of intermediaries and their capacities for innovation and lack of networks needed for communities to make use of the information provided through ICTs.

Practical implications: Although the understanding of communication, innovation and extension has changed substantially in the past two decades, there is still a big gap between theory and practice. This article contends that this gap needs to be bridged if ICTs are to effectively contribute to putting new knowledge into use.

Originality/value: The article manifests the necessity for ICT based initiatives to be embedded into the renewed understanding of communication and innovation and it moves ICT related debates from merely a success story to a pragmatic world of communication and innovation process.  相似文献

Abstract

Purpose:

Though women are engaged in farming and play a major role in almost every agricultural operation, they continue to receive very limited extension support. While several interventions have been made to address this ‘gender’ bias in extension delivery, there continues to be a shortfall between the kind of support that is provided and the needs and demands of rural women. This gap between supply and demand needs to be addressed in order to improve the lives and livelihoods of women in the rural farming sector.  相似文献

To investigate the effects of antiphospholipid antibodies on establishment of pregnancy and changes in hormones such as estradiol-17ß (E2) and progesterone (P) levels in circulation. Hence, mice were immunized with human β2-Glycoprotein I (β2GPI) and the effect of these antibodies on fetuses weight, placental obsrvation, Serum levels of P and E2 in pregnant mice, hematological were observed. Immunization of mice with human β2-GPI resulted in elevated levels of antiphospholipid antibodies. The experimentally induced antiphospholipid syndrome mouse showed higher rate of fetal resorption, low number of viable fetuses, and “placental abnormalities”. In these animals, serum E2 and P levels were reduced significantly. In addition, the blood cell variation among APS induced and control mice were determined. No significant variations were observed in number of Red Blood Cell count, White Blood Cell count and Hemoglobin content, while platelet number was significantly reduced as compared to control. These results clearly demonstrate that human β2-GPI might be involved in causing gestational failure in APS by exerting their effect on serum hormones.  相似文献

The aim of this research is to consider an analysis through case studies on how knowledge sharing may be successfully implemented. The study will clarify a conceptualisation that provides a new understanding of the relationship between unemployed graduates and the human capital concept. The cases adopted web documentation for the research technique, and an interpretive approach was used as the research paradigm. Two online recruitment agency sites were analysed through qualitative analysis. The connections show how knowledge sharing can be used as a medium to help unemployed graduates to get jobs through online recruitment agencies. High quality candidates must have good soft skills, problem-solving skills and employable value added skills to get the best jobs. The findings will be expressed as qualitative results from the two online recruitment agencies researched as the case studies for the paper. From these case studies, the findings will contribute to the ongoing study on how to implement knowledge sharing among undergraduates after they finished their studies.  相似文献

Teachers are often urged to use a variety of modes of instruction to ensure that diverse student interests and abilities can be accomodated. Yet teachers can be limited in the instructional modes they can use because of insufficient background or knowledge about a specific instructional mode (Dawson, 2004). Teaching approaches are various in purposes such as to trigger students' interest in science, to discover through inquiry approach, to build students understanding through constructivism approach or to introduce a concept through demontration approach. Every approach has the strength and weakness in its use. Although inquiry may not be the only way to teach science, many science educators believe that it may be the best way for students to learn science (Audet & Jordan, 2005). According to Woolfolk (2001), constructivism is a mode of instruction that emphasizes the active role of the learner in building, understanding and making sense of information. Demonstrations by teacher can be used with students of all ages and across all subjects. The teacher is not only knowledgeable about the topic but also uses a variety of aids to ensure that students understand what is being demonstrated (Marsh, 2004). By studying their teaching approaches and methods, the actual practices could be analysed and the effectiveness status of their effectiveness could be determined. Specifically, this study aimed to answer these questions in terms of three approaches namely inquiry, constructivism and demonstrations; how far is this approach effective in terms of teaching and learning, and what is the correlation between these three approaches. Data were collected from primary school science teachers (N=239) and the results shown that the teachers were agreeable with the three approaches, inquiry approach (mean=3.74, SD=0.27), demonstration approach (mean=3.61, SD=0.27) and constructivism approach (mean=3.86, SD=0.30). The results also showed that there are significant correlations among inquiry, demonstration and constructivism approach. This finding showed that primary school science teachers not depend only on one type of approach and apply variously in teaching science. There are also positive and significant correlation between that approaches used by primary school science teachers.  相似文献

This classroom observation study explored how science teachers (N = 22) teach for creativity in grades 5–10 in Oman. We designed an observation form with 4 main categories that targeted the instructional practices related to teaching for creativity: questioning strategy, teacher’s responses to students’ ideas, classroom activities to support creativity, and whole-lesson methods that foster creativity. An open-ended survey was also designed to explore participants’ justifications for their instructional decisions and practices. The findings indicate that the overall level of teaching for creativity was low and that participants’ performance was the highest for teacher’s responses to students’ ideas category and the lowest for classroom activities to support creativity category. We observed that a teacher-centered approach with instructional practices geared toward preparing students for examinations was dominant and that these science teachers were bound to the textbook, following cookbook-style activities. Participants believed that they did not have enough time to cover the content and teach for creativity and that they were not prepared to teach for creativity. Based on these findings, we recommend that programs be developed to prepare science teachers to teach for creativity.

Abstract

This article discusses how extension should be taught at the undergraduate, M.Sc. and Ph.D level in India. Major changes are needed to prepare students to work in a rapidly changing environment. Extension education is at present in a crisis, because it has not yet adjusted to these changes. As extension graduates are not prepared to perform the roles the market demands, they have difficulties to find a job. In order to prepare the students for the present needs, more training is needed in participatory extension approaches, organizing farmers’ groups, planning extension strategies to meet farmers’ needs, Human Resource Development and the use of Information and Communication Technologies. The students ought to learn how to apply theories in these areas in the field situation. For this purpose not only agricultural graduates, but also other social scientists should participate in teaching extension. It should become clear which students will be trained to become an extension field worker, and extension manager or an extension researcher. J Agr Educ Ext (2000, 7 2, pp 69–78)  相似文献

Information protection is of paramount importance in today's world. From information involving the highest level of government administration and national security, to information existing at the level of the private company in the form of trade secrets or personal data, all are under the constant threat of being compromised. In this study, the researchers attempt to evaluate the information security maturity level and provide clear thoughtful analysis of the information security landscapes of the Malaysian Public Service (MPS) organizations. This study uses convenience sampling and the required data collected from 970 targeted individuals through a self-administrated survey. In addition, a survey questionnaire is utilized to gauge the security landscape and to further understand the occurrence of incidents, the sources of attack, and the types of technical safeguard. Findings revealed that the highest security incidents experienced by the MPS were spamming (42%), followed by attacks of malicious codes (41%). Twenty-five percent of incidents originated from within the organizations, 15% originated from outside, and 11% were from a mixture of internal and external sources. Also, it shows that 49% of incidents were from sources unknown to the respondents. The top most deployed safeguards by the MPS were found to be firewalls (95%), followed by anti-virus software (92%), and access control to information system (89%). Findings on the maturity level show that 61% of respondents are at Level 3, followed by 21% at Level 2 where the information security processes are still considered an Information and Communication Technology (ICT) domain. At the higher end of the continuum lies 13% for Level 4 and 1% at Level 5.  相似文献
