财经类院校大学数学分层分类教学实践探讨     

柴啸龙  胡桂武 《科教文汇》2012,(9):101-102

财经类院校中,不同专业的学生对数学要求差别较大,对数学原理和计算方法的要求程度都存在很多不同。同时随着社会经济的迅速发展,很多专业对大学数学的知识需求也越来越细化,有时候甚至需要量身定做。因此有必要对大学数学进行分层分类教学。从几个不同方面探讨了在财经类院校中大学数学进行分层分类教学的做法和意义,分析了一些需要进一步解决的问题。  相似文献   

高职经济数学“案例与实验”教学浅试     

刘广丽  柴孟东 《中国科技信息》2012,(7):211

高职教育要培养学生有较强的职业综合能力和解决实际问题的能力,而传统的教学内容和方法存在一个最主要的问题就是理论与实际联系不够紧密,对于高职数学教学来说,更是如此。为改变这种状况,采用"案例与实验"相结合的方法,通过利用计算机软件,使学生探索解决一些典型数学问题的方法,可培养学生的数学应用能力和创新思维能力。  相似文献   

Danshen protects endothelial progenitor cells from oxidized low-density lipoprotein induced impairment     

Kang-ting Ji  Jun-de Chai  Cheng Xing  Jin-liang Nan  Peng-lin Yang  Ji-fei Tang 《Journal of Zhejiang University. Science. B》2010,11(8):618-626

In this study,we examined the protective effects of Danshen both on endothelial progenitor cells(EPCs) in patients with hypercholesterolemia and on in-vitro EPCs of healthy volunteers.In the clinical study,we randomly divided 24 subjects with hypercholesterolemia into two groups(the control group and the Danshen-treated group).At the end of two weeks of treatment,the EPC cellular functions of both groups were tested.The results indicated that,compared to the control group,EPCs in the Danshen-treated group showed significantly better cellular functions,which was manifested in the cloning number,the proliferation capacity,the number of EPC adhesions,and cell migration.In the subsequent in-vitro experiments,EPCs were treated with vehicle,oxidized low-density lipoprotein(Ox-LDL,100 μg/ml),or Ox-LDL(100 μg/ml) plus different concentrations of Danshen(Danshensu 2,10,or 50 μg/ml,respectively) for 24 h.The results showed that Danshen treatments can prevent the detrimental effects of Ox-LDL on EPC cellular functions measured by proliferation capacity(0.24±0.08,0.37±0.11,0.30±0.04 vs.0.13±0.02,P0.05,P0.01,and P0.01,respectively),and adhesion ability(63.00±11.60,70.00±10.80,85.50±11.41 vs.40.50±6.85,all P0.01).Compared to the group treated with Ox-LDL alone,Danshen treatment significantly decreased the lipid peroxidation end product malondialdehyde(MDA) [(4.34±0.54),(3.98±0.47),(3.46±0.31) vs.(5.57±0.64) nmol/ml,all P0.01],increased the production of superoxide dismutase(SOD) [(29.74±0.71),(31.09±0.83),(30.41±0.65) vs.(14.76±3.99) U/ml,all P0.01],and lowered the expression of interleukin-6(IL-6) [(24.62±7.69),(27.04±3.14),(33.38±18.86) vs.(230.67±33.53) pg/ml,all P0.01] and tumor necrosis factor-α(TNF-α) [(41.72±6.10),(17.02±6.82),(3.73±2.26) vs.(228.71±41.53) pg/ml,all P0.01] in Ox-LDL treated EPCs.These results suggest that Danshen may exert a protective effect through its antioxidant and anti-inflammatory features.  相似文献   

School‐to‐work transition services for students with disabilities in Malaysia: organisations' views on policy and practices     

Melissa Ng Lee Yen Abdullah  See Ching Mey  Tan Kok Eng  Rosly Othman  Ahmad Fairuz Omar 《Journal of Research in Special Educational Needs》2013,13(4):259-271

Transition services are required by law for students with disabilities in many developed countries. In Malaysia, however, there is still no specific legislation mandating that school‐to‐work transition planning and services be provided to students with disabilities. This study investigated the state of the transition services provided by educational organisations to students with disabilities in Malaysia. A mixed method research design, which utilises both quantitative and qualitative research techniques, was employed to obtain information from 23 government organisations and NGOs involved in the education and training of students with disabilities. This study found that the organisations surveyed were aware of the lack of transition support and call attention to the importance of instituting a national policy on school‐to‐work transition services and supported employment systems for students with disabilities. The legislative and educational implications for Malaysia are discussed.  相似文献   

高校校报通过校园媒体纵向整合快速转型研究     

柴扉菲  李威 《沈阳教育学院学报》2013,15(3):427-430

研究了高校校报在媒体数字化浪潮冲击下所面临的形势,认为实现校报全面转型势在必行。高校校报应借助校园媒体纵向整合,通过实现校报的数字化、互动性,推动与其他校园媒体形式的互动,实现功能融合,完成全面转型。高校校报的功能定位和其他校园媒体的自身弱点决定了高校校报必须在校园媒体纵向整合中发挥主导作用和新闻宣传主渠道的优势,利用校园新媒体的积极因素实现全面转型。  相似文献   

Validation of the swimming competence questionnaire for children     

Derwin K. C. Chan  Alfred Sing Yeung Lee  Duncan J. Macfarlane  Martin S. Hagger  Kyra Hamilton 《Journal of sports sciences》2020,38(14):1666-1673

ABSTRACT

Two studies were employed to test the reliability and validity of the Swimming Competence Questionnaire (SCQ) among primary school children. Study 1 was a cross-sectional survey in 4959 primary school children. Study 2 was a pre-post-test quasi-experiment among 1609 primary school children who underwent a 20-lesson learn-to-swim programme. In Study 1, exploratory structural equation modelling revealed excellent goodness-of-fit and scale reliability for a two-factor model comprising distance and skill factors, which supported the construct and convergent validity. SCQ scores were significantly and positively correlated with swimming outcomes (i.e., self-efficacy, intention, swimming frequency), which supported SCQ’s concurrent and criterion validity. Average variance extracted for the SCQ factors exceeded cut-off criteria supporting discriminant validity. In Study 2, pre-test SCQ scores correlated significantly and positively with the SCQ scores, self-efficacy, intention, and swimming frequency at post-test, which supported SCQ’s test-retest reliability and predictive validity. Positive intraclass correlation between SCQ scores and coach ratings at post-test provided evidence for SCQ’s inter-rater reliability. SCQ scores significantly improved at post-test, which supported SCQ’s ecological validity. In conclusion, findings indicate that the SCQ is a valid and reliable measure to assess primary school children’s swimming competence, in terms of swimming distance and basic water survival skills.  相似文献

行业与高职教育的专业研究   总被引：1，自引：0，他引：1  

柴福洪 《黄冈职业技术学院学报》2008,10(4):34-37

高等职业教育,是我国高等教育在发展中的新类型,它与传统高等教育的最大不同是不以学科体系为依托培养学术型研究人才,而是以培养职业技能为核心的高等教育。因此,高职教育的院、系设置与专业设置的依据也应随之变化。通过分析行业与产业、职业、工作岗位的关系和院系设置与边界,认为应按行业设置院系,按职业设置专业;同时,高职专业有行业纵向发展的“经专业”,还有技术岗位横向发展的“纬专业”。  相似文献
