中国高职教育的新实践、新理论、新发展     

陈年友  柴福洪 《黄冈职业技术学院学报》2007,9(4):35-37

近十年,大批高职院校在中华大地上涌现,由于高职教育理论、教学模式、教学方法准备不充足,各院校都在摸索中前进。经过近十年的实践与探索,产出了一大批高职教育研究成果,这些成果在高职院校的教育教学中,还没有得到广泛应用,很有必要以某种形式在高职院校中推行,让新的理论与方法在应用与实践中升华。高职教育作为整体,目前存在着许多难以克服的困难和问题。研究如何应用最新研究成果,形成中国特色的高职教育体系、理论框架和实践模式,是全体高职人面临的新课题。如果在这些课题研究中有所进展、有所突破,中国高职教育一定有望成为世界典范。  相似文献

Embryogenic calli were induced from the seeds of creeping bentgrass (Agrostis palustris Huds.) cv. Regent and colonial bentgrass (Agrostis Tenuis Sibth. Fl. Oxen.) cv. Tiger. The embryogenic calli were precultured on fresh medium for 4–7 days and then co-cultivated withAgrobacterium tumefaciens, LBA4404. which contains plasmid vector-pSBGM harboring bar coding region, synthetic green fluorescent protein (sGFP) coding region and matrix attachment region (MAR). After 3 days of co-cultivation, the calli were washed thoroughly and transferred to MS medium containing 2 mg/L of 2, 4-D, 12–15 mg/L phosphinothricin (PPT) and 250 mg/L of cefotaxime. After 2–3 months of selection, the actively growing calli of ‘Regent’ and ‘Tiger’ were transferred to MS medium with 12–15 mg/L PPT and 250 mg/L cefotazime for regeneration. The putative transformants were maintained on MS medium with 3 mg/L PPT for long period but control died within 1 month. After establishing in greenhouse, the transformants also showed strong resistance to 0.4% of herbicide Basta but control plants died within 2 weeks. Under confocal microscope, both young leaves and roots showed significant GFP expression. PCR analysis revealed the presence of a DNA fragment of GFP gene at the expected size (380 bp) in the transformants and its absence in a randomly selected control plant.  相似文献

激光靶测速相对误差影响因素研究     

周强  柴黎娜 《实验技术与管理》2012,(4):313-315,318

激光靶测速是速度测量的一种重要的实验方法,其测试效率高、精度高、抗干扰能力强、测速范围大、受环境因素影响小,很有工程应用前景。针对激光靶速度的实际工程应用背景,深入、系统地研究了在匀加速阶段和匀速阶段测速时影响测速相对误差的因素,得出了在这两个典型阶段测速时,激光靶的安装位置及其精度与测速相对误差的重要关系。同时,分析得到了在给定测速相对误差前提下,激光靶的最佳安装间距。上述结果对激光靶测速的相关工程应用和相关实验的设计与开发具有重要的指导意义。  相似文献

Assessing South China (Guangzhou) High School Students’ Views on Nature of Science: A Validation Study     

Feng Deng  Ching Sing Chai  Chin-Chung Tsai  Tzung-Jin Lin 《Science & Education》2014,23(4):843-863

Research on students’ views on nature of science (VNOS) in Asian countries such as China is notably lacking. This study aimed to develop and validate an instrument to measure South China high school students’ VNOS. Based on the previously acquired qualitative data, the instrument included seven VNOS dimensions which reflect the crucial aspects of NOS indicated by the literature and/or the dominating ideology in China (i.e., Marxism). A sample (N = 604) was randomly divided into two groups used for exploratory analyses and confirmatory analyses. The results indicated that the instrument expressed satisfactory reliability and validity and the seven NOS dimensions could be explained by a higher-order dimension. That is, the data of this study supported the multi-dimensional framework that treats VNOS as comprising several more-or-less correlated dimensions. Two distinct dimensions, namely “Accumulative-Empirical Source” and “Pragmatic Justification” which have not been explicitly specified in the past literature, were found. In addition, the Chinese high school students generally held a constructivist/relativist-oriented view of all seven dimensions. Differences in gender and grade level were hardly observed in any dimension of the instrument. The findings are further discussed through a socio-cultural lens to enrich the current understanding of VNOS.  相似文献   

Periodontal status and associated risk factors among childbearing age women in Cixi City of China     

Yan-min WU  Jia LIU  Wei-lian SUN  Li-li CHEN  Li-guo CHAI  Xiang XIAO  Zheng CAO 《Journal of Zhejiang University. Science. B》2013,14(3):231-239

Objective:To investigate the periodontal status and associated risk factors among women of childbearing age to increase the awareness of oral health.Methods:The study was conducted on childbearing age women in Cixi,a city in Zhejiang Province in the southeast of China.A total of 754 women participated in periodontal examination while receiving prenatal care.Data of the women were collected from the Cixi Family Planning Commission and during an interview.Clinical periodontal indices,such as bleeding on probing(BOP),probing depth(PD),and clinical attachment level(CAL) were measured during the examination.Statistical analysis on subject-based data was performed.Results:The prevalence of periodontal disease among childbearing age women in Cixi was high(84.7%).A significant association was found between the disease and educational level,pregnancy,taking oral contraceptives,stress,alcohol consumption,overweight,dental visit,and teeth brushing(P<0.05).Women who suffered periodontal disease showed deep PD,obvious BOP,and clinical attachment loss.Among this population,pregnancy was closely associated with higher BOP percentage;teeth brushing no more than once per day or brushing for less than 1 min(P<0.001) after adjusting for age and stress.Conclusions:The periodontal status of childbearing age women in Cixi needs to be improved urgently.Attention towards the periodontal health should be warranted,especially for those in special statuses and with poor awareness.  相似文献

一切的声乐技能都是靠自己的意识来控制发声器官的,按照意识预定要求进行动作结果的。发声的各个器官的互相搭配其实也是人的一种本能的意识反应,建立科学发声状态是通过自身感觉的调控,使复杂的肌肉运动准确化、歌唱运用共鸣和呼吸合理化、技巧的掌握简单化,最后实现演唱的自动化。  相似文献   

High school students’ scientific epistemological beliefs,motivation in learning science,and their relationships: A comparative study within the Chinese culture   总被引：1，自引：0，他引：1  

Tzung-Jin Lin  Feng Deng  Ching Sing Chai  Chin-Chung Tsai 《International Journal of Educational Development》2013

This study explored the differences in high school students’ scientific epistemological beliefs (SEBs), motivation in learning science (MLS), and the different relationships between them in Taiwan and China. 310 Taiwanese and 302 Chinese high school students’ SEBs and MLS were assessed quantitatively. Taiwanese students generally were more prone to believe that scientific reality is invented, the development of scientific knowledge is culture-dependent, and scientific knowledge is always changing and its status is tentative than the Chinese students were. Yet, the Taiwanese students perceived higher test anxiety in science than the Chinese students did. Moreover, Chinese students who have a stronger belief that science knowledge is changing and tentative are more likely to perceive themselves as having higher test anxiety in science. The results suggest that the role of culture might have an impact on students’ SEBs and their MLS.  相似文献
