The study described in this article takes the view that distance education programs are dynamic systems with multiple constituencies.
Literature on distance education programs as complex systems and on the critical constituency approach to program evaluation
was used to guide the development of a questionnaire designed to assess the components of a distance education program. Instrument
development was conducted in four phases using both quantitative and qualitative methods. The data from this study suggest
that there are four major components of effectiveness in distance education programs: instruction, management, telecommuting,
and support. Within each of these components there are from two to five subcomponents, 14 components in all, which can be
used to assess distance education programs. The assessment scale which was developed measures these four components and their
subcomponents. 相似文献

While technological improvements of the computer supported collaborative learning (CSCL) have been substantial, its nontask social aspect has not received proportional attention. This study investigates the notion of nontask sociability of CSCL, and identifies its relationship with the students' learning outcomes using the case of an Australian postgraduate programme. Learning outcome is defined as a multiple variable consisting of pedagogical affect, student's interest and perceived learning. Five items were identified for operationalising the nontask sociability. These are ‘finding help’, ‘sense of appealing’, ‘sense of boringness’, ‘sense of interactivity’ and ‘sense of frustration’. In addition, a strong relationship was revealed between nontask sociability and learning outcomes which implies that further attention needs to be given to the nontask aspect of the CSCL interactions. Theoretical and practical implications of the findings are then discussed. 相似文献

Objective: The purpose of this study is to analyse Iranian scientific publications in the neuroscience subfields by librarians and neuroscientists, using Science Citation Index Expanded (SCIE) via Web of Science data over the period, 2002–2008. Methods: Data were retrieved from the SCIE. Data were collected from the ‘subject area’ of the database and classified by neuroscience experts into 14 subfields. To identify the citation patterns, we applied the ‘impact factor’ and the ‘number of publication’. Data were also analysed using HISTCITE, Excel 2007 and SPSS. Results: Seven hundred and thirty‐four papers have been published by Iranian between 2002 and 2008. Findings showed a growing trend of neuroscience papers in the last 3 years with most papers (264) classified in the neuropharmacology subfield. There were fewer papers in neurohistory, psychopharmacology and artificial intelligence. International contributions of authors were mostly in the neurology subfield, and ‘Collaboration Coefficient’ for the neuroscience subfields in Iran was 0.686 which is acceptable. Most international collaboration between Iranians and developed countries was from USA. Eighty‐seven percent of the published papers were in journals with the impact factor between 0 and 4; 25% of papers were published by the researchers affiliated to Tehran University of Medical Sciences. Conclusion: Progress of neuroscience in Iran is mostly seen in the neuropharmacology and the neurology subfields. Other subfields should also be considered as a research priority by health policymakers. As this study was carried out by the collaboration of librarians and neuroscientists, it has been proved valuable for both librarians and policymakers. This study may be encouraging for librarians from other developing countries. 相似文献

To determine the concentration of ionized calcium (iCa) collected in lithium heparin and gel tubes and to correlate the measured iCa with calculated iCa. Anaerobic fasting blood samples were simultaneously collected from healthy laboratory workers in lithium-heparin and gel tubes. iCa, pH, total calcium (CaT), total protein and albumin were measured. Ionized Ca was calculated with albumin and globulin values using an appropriate formula. Mean iCa in gel tubes showed a positive constant bias of 0.08 mmol/L (p < 0.001) when compared to lithium heparin results. The mean pH of blood taken in lithium heparin and gel tubes was non-significant (p = 0.3). Measured iCa poorly correlated with CaT (r = 0.2, p = 0.1) and calculated iCa (r = 0.2, p = 0.2). To evaluate the calcium status direct measurement of iCa must be done rather than using the formulae for iCa determination. In addition serum is recommended as the choice of sample for iCa determination in comparison to plasma samples. 相似文献

Many teacher education programs provide teachers with opportunities to read, write, and discuss critical pedagogy, with the hope that such work will allow them to develop more equitable and just teaching practices. Yet, there often remains a gap between the theoretical discussions of teaching and learning in teacher education classrooms and the pedagogical practice in those teachers’ K-12 classrooms. In this study, we examine how one teacher, Gabriela, used narratives to make connections between her third-grade classroom and the critical concepts she was exploring in a teacher education course. Embedded within an ethnographic case study of an inservice teacher education program, we used a discourse analytic approach to examine both the sociocultural knowledge and the identities Gabriela constructed through narrative as she engaged with issues of language, race, and power within the course. We consider some of the affordances of narrative in this space, including how it allowed Gabriela to integrate her understandings of multiple course topics, to position herself in multiple ways as a teacher, and to disrupt her existing understandings of race and racism in the classroom. This analysis suggests that critically oriented teacher education programs might more intentionally make space for narrative to connect critical theory and pedagogical practice. 相似文献

The performance enhancement of dynamic systems is accomplished by the application of active control components. Control strategies are derived to accomplish the task. Among the various control strategies, those that are designed to minimize a specified cost function while satisfying the necessary system constraints are referred to as optimal controllers. An important constraint is the amount of power and energy consumed by the control device. In this paper, the effect of optimal control strategies on the power and energy requirement of control devices is investigated. 相似文献

In a world marred by the fears of religious extremism, Muslim women have become subjects of various global projects that aim to modernize ‘traditional’ Muslim societies through women’s education and empowerment. Embedded in these discourses is an assumption that all educated Muslim women will empower themselves through challenging the ‘oppressive’ structures of their families and communities. This paper challenges these homogeneous narratives of education and empowerment through highlighting the complexities of educated women’s daily lives in rural Pakistan. We situate the lived experiences of rural educated Pakistani women in global mainstream as well as in local historical narratives regarding the role and purpose of education for women. Our analysis reveals how the educated women participants’ lives were shaped by a complex gendered hierarchy that facilitated educated women to take on new roles while simultaneously requiring them to maintain harmonious relationships with family and community members. 相似文献
