Currently, instructional design theorists are generating new enhancements of traditional design models on both macro and micro levels. This paper summarizes the anticipated changes in instructional design models that will result from today's theoretical activity. It addresses issues such as linearity in the design process, enhanced roles of analysis and evaluation, and the new emphasis on learner control and transfer of training. These model enhancements are being influenced by new interpretations of general systems theory and cognitive learning theory, constructivism, chaos theory, and situated cognition. Predicted model changes also reflect the impact of the new technologies, designer decision-making research, and the performance technology and total quality management movements. These and other intellectual forces are likely to produce diverse models for future designers. 相似文献

The research undertaken for this article aims to analyse the correspondence between perceived employability and the actual national employment rate among Italian students and graduates undertaking different courses in a large Italian university. Data were collected through a cross-sectional survey of 2087 students in 19 faculties, and compared with the national indicators of employment rate for each faculty. Using faculty as unit of analysis, the results indicated a significant correlation between participants’ perceived employability and national employment rate. This trend was similar for both genders. However, the results showed a difference between bachelor’s and master’s degrees: the correlation between perceived and actual employability was not significant among bachelor’s participants while it remained significant among master’s participants. The results suggest that graduates are only partially aware of their possibility to enter the labour market and this, in turn, highlights that universities have only partially met the goal to increase awareness about the chances of finding a job among students and graduates. 相似文献

Adult development and adult learning styles: The message for nontraditional graduate programs 总被引:1,自引:0,他引:1
Both the content and process of graduate education promote adult development. As developing people, adults usually enroll in graduate programs at times when they are building or changing the structure of their lives. Graduate programs, particularly nontraditional programs, can address both the growing adult as well as uphold relevant standards of intellectual excellence and professional expertise.Their collaborative research has focused on life cycle adult development and on educational methodologies and environments which support adult development. 相似文献

Introduction
Glycolysis affects glucose determination in vitro. The placement of sample tubes in ice-water slurry with plasma separation within 30 minutes is recommended, or alternatively the use of a glycolysis inhibitor. The aim of our two-steps study was to evaluate which Terumo tube is best for glucose determination in routine clinical setting.Materials and methods
In the first study, blood from 100 volunteers was collected into lithium heparin (LH), NaF/Na heparin (FH) and NaF/citrate buffer/Na2EDTA (FC-Mixture) tubes. LH sample was treated as recommended and considered as reference, while FH and FC-Mixture samples were aliquoted, maintained at room temperature (RT) for 1, 2 and 4 hours; centrifuged and plasma analysed in triplicate. In the second study, samples from 375 volunteers were collected in LH, FH and FC-Mixture tubes and held at RT before centrifugation from 10 to 340 minutes, depending on each laboratory practice. Samples were analysed in one analytical run.Results
In the first study, FH glucose concentrations were 5.15 ± 0.66 mmol/L, 5.05 ± 0.65 mmol/L and 5.00 ± 0.65 mmol/L (P < 0.001) in tubes stored at RT for 1, 2 and 4 hours, respectively. Mean biases in all time points exceeded the analytical goal for desirable bias based on biological variation criteria. FC-Mixture glucose concentrations were 5.48 ± 0.65 mmol/L, 5.46 ± 0.6 mmol/L and 5.46 ± 0.64 mmol/L in tubes stored at RT for 1, 2 and 4 hours, respectively. Mean biases for FC-Mixture glucose in all time points reached optimal analytical goals. In the second study, the biases for LH and FH glucose compared to reference FC-Mixture glucose exceeded the preset analytical goals, regardless of the blood collection to centrifugation time interval.Conclusions
FC-mixture tubes glucose concentrations were preserved up to 4h storage at RT. We confirmed that NaF alone does not allow immediate glycolysis inhibition in real life pre-centrifugation storage conditions (up to 340 minutes). FC-Mixture should be used exclusively for glucose determination in laboratories unable to implement the recommended blood samples’ treatment.Key words: glucose, pre-analytical phase, sodium fluoride, citrate acidification, stability 相似文献87.

Myocardial infarction is a major consequence of coronary artery disease. Apart from the traditional risk factors of myocardial
infarction, recently many reports have suggested that hyperhomocysteinemia plays important role in myocardial infarction.
Plasma homocysteine level was determined in 60 myocardial infarction patients and in 35 age matched healthy individuals. Statistically
significant differences (p<0.01) were observed in the mean of plasma homocysteine concentrations between the acute myocardial
infarction patients (24.59±6.14 mM/L) and in normal healthy individuals (13.73 ±3.54 mM/L). The level of homocysteine in myocardial
infarction patients is significantly high (p <0.01) among myocardial infarction patients when compared to that of the controls.
The the present study indicates a strong association between plasma homocysteine and acute myocardial infarction among Tamilians,
thus implying plasma homocysteine as a possible risk factor for myocardial infarction. 相似文献

Rita Jordan 《British Journal of Special Education》2008,35(1):11-15
Rita Jordan, Professor in Autism Studies at the School of Education, University of Birmingham, gave last year's Gulliford Lecture at the University of Birmingham on 4 October 2007. This article is based upon that lecture. In it, Professor Jordan discusses the role of education in the lives of people with autistic spectrum disorders. She traces the growth in our knowledge about autistic spectrum disorders and the development of a variety of ways of responding to autism, from the highly specialised, and frequently strictly segregated, to the explicitly inclusive. She uses her analysis to draw distinctions between 'therapeutic' models of education and education as 'entitlement'– and identifies problems with either paradigm. Professor Jordan closes her article by setting out her vision for a future in which there is greater flexibility and diversity and in which specialisation has a key role to play in making inclusion a working reality. The challenge of teaching pupils with autistic spectrum disorders will, argues Professor Jordan, help us all to imagine a truly inclusive model for education in which equity is achieved by treating all learners differently. 相似文献

The role of context in learning and instructional design 总被引:4,自引:0,他引:4
Martin Tessmer Rita C. Richey 《Educational technology research and development : ETR & D》1997,45(2):85-115
Context is a pervasive and potent force in any learning event. Yet instructional design models contain little guidance about how to accommodate contextual elements to improve learning and transfer. This paper defines context, outlines its levels and types, specifies some pertinent contextual factors within these types, suggests methods for conducting a contextual analysis and utilizing its results for instructional design, and outlines future issues for context-based instructional design. The incorporation of a contextual approach to instruction will make our design models systemic as well as systematic. 相似文献
