问题式教学法对工科大学生批判性思维倾向影响的实证研究     

田社平  王力娟  邱意弘 《高等工程教育研究》2018,(6):156-160

采用不相等实验组对照组前后测准实验研究,并辅以行为观察数据和质性资料分析,探究在"基本电路理论"课程教学中采取问题式教学法促进工科大学生批判性思维倾向的发展。研究表明,问题式教学对工科大学生的批判性思维倾向有显著的促进作用。作者认为,为有效开展问题式教学以促进学生批判性思维发展,应注意:(1)教师需具备良好的批判性思维精神;(2)积极营造良好的思考情境和氛围,鼓励与引导学生发现和解决问题;(3)应根据学生基础设置难易适当的问题,营造问题讨论的安全教学氛围;(4)积极引导讨论小组确定合适的讨论问题和组内讨论规则,充分利用信息技术辅助教学。  相似文献

高等工程教育正面临着来自外部和内部的双重挑战,大学需要从学科、产业、社会、人才成长等四个维度重构以学生为中心的工程学习共同体。华南理工大学以高端工程科技人才培养为目标,以"4I"(交叉复合、产学研合作、国际化教学、深度工程学习)为路径,推进工程人才培养模式改革,取得了显著成效。  相似文献   

Four pitfalls in normalizing citation indicators: An investigation of ESI’s selection of highly cited papers     

Zhigang Hu  Wencan Tian  Shenmeng Xu  Chunbo Zhang  Xianwen Wang 《Journal of Informetrics》2018,12(4):1133-1145

InCites Essential Science Indicators is becoming increasingly used to identify top-performing research and evaluate the impact of institutes. Unfortunately, our study shows that ESI indicators, as well as other normalized citation indicators, have the following flaws. First, the publication month and the online-to-print delay affect a paper’s probability of becoming a Highly Cited Paper (HCP). Papers published in the earlier months of the year are more likely to accumulate enough citation counts to rank at the top 1% compared with those published in later months of the year. Papers with longer online-to-print delays have an apparent advantage for being selected as HCPs. Research field normalizations lead to the third pitfall. Different research fields have different citation thresholds for HCPs, making research field classification important for a journal. In addition, the uniform thresholds for both articles and reviews in ESI affect the reliability of HCP selection because, on average, reviews tend to have higher citation rates than articles. ESI’s selection of HCPs provides an intuitive feel for the problems of normalized citation impact indicators, such as those provided in InCites and SciVal.  相似文献   

跨文化效力与我族中心主义的相关性研究简

本研究采用跨文化效力量表和普遍我族中心主义量表，调查了大学生跨文化效力和我族中心主义的基本情况及相关关系。结果表明：（1）中文版跨文化效力量袁和普遍我族中心主义量表具有较高的可靠性；（2）大学生跨文化效力和我族中心主义均处于中等水平，在跨文化效力的6项因素中，大学生的尊重对方最强，随后依次是认同维护、互动管理、互动放松、行为弹性，而信息技巧最弱；（3）跨文化效力的6项因素间存在较强的相关关系，量表具有较高的内部有效性；（4）跨文化效力和我族中心主义之间呈显著负相关关系；（5）跨文化效力在性别上无显著差异，我族中心主义性别差异显著。  相似文献   

Simultaneous changes in seed size,oil content and protein content driven by selection of SWEET homologues during soybean domestication     

Shoudong Wang  Shulin Liu  Jie Wang  Kengo Yokosho  Bin Zhou  Ya-Chi Yu  Zhi Liu  Wolf B Frommer  Jian Feng Ma  Li-Qing Chen  Yuefeng Guan  Huixia Shou  Zhixi Tian 《国家科学评论(英文版)》2020,7(11):1776

Soybean accounts for more than half of the global production of oilseed and more than a quarter of the protein used globally for human food and animal feed. Soybean domestication involved parallel increases in seed size and oil content, and a concomitant decrease in protein content. However, science has not yet discovered whether these effects were due to selective pressure on a single gene or multiple genes. Here, re-sequencing data from >800 genotypes revealed a strong selection during soybean domestication on GmSWEET10a. The selection of GmSWEET10a conferred simultaneous increases in soybean-seed size and oil content as well as a reduction in the protein content. The result was validated using both near-isogenic lines carrying substitution of haplotype chromosomal segments and transgenic soybeans. Moreover, GmSWEET10b was found to be functionally redundant with its homologue GmSWEET10a and to be undergoing selection in current breeding, leading the the elite allele GmSWEET10b, a potential target for present-day soybean breeding. Both GmSWEET10a and GmSWEET10b were shown to transport sucrose and hexose, contributing to sugar allocation from seed coat to embryo, which consequently determines oil and protein contents and seed size in soybean. We conclude that past selection of optimal GmSWEET10a alleles drove the initial domestication of multiple soybean-seed traits and that targeted selection of the elite allele GmSWEET10b may further improve the yield and seed quality of modern soybean cultivars.  相似文献   

教师教育U-S合作的结构性障碍与路径选择     

张翔 《辽宁教育研究》2014,(6):95-99

大学与中小学(U-S)合作是当前教师教育的一条有效出路。但目前我国教师教育U-S合作过程存在严重的结构性障碍,主要表现为合作中的异质性资源依赖感不强,合作主体的合法性认同严重不足,合作协调机制缺位。因此,我们需要充分挖掘U-S合作中的异质性资源,增强双方异质性资源依赖程度;赋予中小学教师教育义务并提升合作双方的利益共识,增强合作主体的合法性认同;构建政府统筹的U-S合作管理体制,规范合作行为。  相似文献

传统、现代、后现代与中国哲学的价值   总被引：3，自引：0，他引：3  

向世陵 《首都师范大学学报(社会科学版)》2001,(6):1-6

思考中国传统哲学资源在21世纪的价值,离不开西学的参照。由西方传入的现代性与后现代主义为中国哲学的现代转型准备了条件。中国哲学本有的开放性则为这一转型提供了现实的可能。应当在认真总结自身短长的基础上,将西方的现代性精神与中国传统的真善美的价值追求自觉结合起来,“一阴一阳之谓道”的结构模型和变常互动互补的生存机制集中体现了中国哲学的价值。经过与现代性,后现代的相互折衷,必将能够适应新世纪的需要。  相似文献
