Demonstration models allow students to readily grasp theory and relate difficult concepts and equations to real life. However drawbacks of using these demonstration models are that they are can be costly to purchase from vendors or take a significant amount of time to build. These two limiting factors can pose a significant obstacle for adding demonstrations to the curriculum. This article presents an assignment to overcome these obstacles, which has resulted in 36 demonstration models being added to the curriculum. The article also presents the results of student performance on course objectives as a result of the developed models being used in the classroom. Overall, significant improvement in student learning outcomes, due to the addition of demonstration models, has been observed. 相似文献

This study examines the changes that occur in multidimensional self-concept of adolescents with a diagnosis of intellectual disabilities, across gender and category of intellectual disability (borderline, mild, moderate) groups. A sample of 54 young people completed the Harter Self-Perception Profile. Using a three-wave longitudinal study conducted during their first year in a segregated special second-level school, stability and change in multiple domains of self-perception were examined. Findings indicate that gender and level of cognitive function are important variables in changes in self-perception across time, highlighting the heterogeneous nature of the special school population. 相似文献

This paper comes back to the hard problem of pole placement by static output feedback: let a triplet of matrices {A;B;C}∈Rn×n×Rn×m×Rp×n be given, find a matrix K∈Rm×p such that the spectrum of A+BKC equals a specified set. More precisely, this article focuses on the derivation of non-iterative techniques, based upon the notion of eigenstructure assignment, to solve the problem, especially when Kimura's condition does not hold. Some solutions can sometimes be found. 相似文献

This paper reports findings of a study designed to test whether differences in spatial layout of research offices and labs (workspace planning) affects face-to-face technical consultations, and ultimately innovation process outcomes in research settings critical to government supported innovation strategies—university research centers (URCs). The study involved a mixed-method (multivariate predictive and multiple case comparison) evaluation of six organizationally similar but spatially different URCs. Data analysis revealed relationships between workspace planning, consultations and innovation process outcomes. Multivariate analyses showed that configurational accessibility, visibility and walking distances significantly affect the frequencies and locations of unprogrammed face-to-face consultations. Cross-case comparisons revealed that URCs featuring overall high configurational accessibility, shorter walking distances and intact territories exhibit higher face-to-face consultation rates, consultation network connectivity, and subjective/objective innovation process outcomes. Implications for research policy, practice and research are discussed. 相似文献

In the last few years, there is an increasing interest to generate visual representations of very large scientific domains. A methodology based on the combined use of ISI–JCR category cocitation and social networks analysis through the use of the Pathfinder algorithm has demonstrated its ability to achieve high quality, schematic visualizations for these kinds of domains. Now, the next step would be to generate these scientograms in an on-line fashion. To do so, there is a need to significantly decrease the run time of the latter pruning technique when working with category cocitation matrices of a large dimension like the ones handled in these large domains (Pathfinder has a time complexity order of O(n4), with n being the number of categories in the cocitation matrix, i.e., the number of nodes in the network). 相似文献

A distinguishable feature of type 2 diabetes besides hyperglycemia and deranged lipid profile is an impaired insulin secretion,
peripheral insulin resistance and obesity which has become a major health concern worldwide. India with an estimated 31million
diabetics in 2000 and 79mllions by the yr 2030 has the highest number of type 2 diabetics in the world. In this study, we
aimed to see if yoga-asanas and pranayamas have any influence in modifying certain biochemical parameters. Sixty patients
of uncomplicated type 2 diabetes (age 35–60 yrs of 1–10 yrs duration) were divided into two groups: Group 1 (n=30): performed
yoga along with the conventional hypoglycemic medicines and group 2 (n=30): patients who only received conventional medicines.
Duration of the study was 45 days. Basal recordings of blood glucose (fasting and post-prandial), lipid profile and serum
insulin were taken at the time of recruitment and the second reading after forty five days. Results showed a significant improvement
in all the biochemical parameters in group 1 while group 2 showed significant improvement in only few parameters, thus suggesting
a beneficial effect of yoga regimen on these parameters in diabetic patients. 相似文献

The effect of oral administration of vitamin E for twenty-eight consecutive days on blood glucose, reduced glutathione levels,
antioxidant enzymes (superoxide dismutase and catalase activities), and levels of malondialdehyde (as an index of free radical-mediated
lipid peroxidation) was observed in the whole blood and liver of normal and alloxan-induced diabetic rats. It was found that
oral administration of vitamin E significantly (p<0.05) lowered the blood glucose level and increased the body weight of the
diabetic rats. The activities of superoxide dismutase and levels of reduced glutathione increased significantly (p<0.05) while
the level of lipid peroxidation decreased. 相似文献

In order to investigate the effect of methods of teaching on achievement in mathematics of first year National Certificate
of Education (NCE) students in Nigeria, a sample of 165 students comprising 71 males and 94 females, was exposed to three
methods of teaching in a second semester basic mathematics course. The three methods were the traditional lecture method,
interactive method with individual use of materials and interactive method with group use of materials. Analysis of covariance
showed a significant interactive effect of gender and method of teaching on student achievement. Further analysis showed that
the use of interactive methods with group use of materials favoured males while interactive method with individual use of
materials favoured females. Implications of the results for teaching of tertiary mathematics are discussed.

First- and 3rd-year university students were surveyed regarding cultural attitudes and climate. Comfort in cross-cultural situations and respect for other cultures correlated with overall satisfaction for all students. However, the more Asian Americans, Hispanic Americans, and Whites were aware of diversity and changing their behavior accordingly, the less satisfied they were. Awareness of diversity was not related to overall satisfaction for African Americans. 相似文献

Little is known about how animals represent their own actions in working memory. We investigated whether bottlenosed dolphins could recall actions they had recently performed and reveal those recollections using an abstract rule. Two dolphins were trained to respond to a specific gestural command by repeating the last behavior performed. Both dolphins proved to be able to repeat a wide variety of behaviors on command and were able to generalize the repeating rule to novel behaviors and situations. One dolphin was able to repeat all 36 behaviors she was tested on, including behaviors involving multiple simultaneous actions and self-selected behaviors. These results suggest that dolphins can flexibly access memories of their recent actions and that these memories are of sufficient detail to allow for reenactments. The repeating task can potentially be used to investigate short-term action and event representations in a variety of species. 相似文献
