A framework for teaching scientific inquiry in upper secondary school chemistry

A framework for teaching scientific inquiry in upper secondary chemistry education was constructed in a design research consisting of two research cycles. First, in a pilot study a hypothetical framework was enriched in collaboration with five chemistry teachers. Second, a main study in this community of teachers and researchers was conducted on the process of designing teaching scientific inquiry based on the enriched framework. Also, the enactment by five teachers and 80 students (age 17) of a designed inquiry module on “Diffusion: moving particles” was studied. This resulted in a theoretically and practically founded framework for teaching scientific inquiry, in which an iterative cycle of inquiry for students and a student inquiry community are essential. © 2009 Wiley Periodicals, Inc.

结合Wiki协作式学习的双语教学模式研究与应用

双语教学作为我国培养国际化人才的有效途径,是高校教学改革的必然趋势。高职院校受学生学习能力与英语水平局限,难以推动双语教学。基于Wiki平台的协作式学习模式的双语教学方法成功地运用于C语言授课,可引导学生使用Wiki进行基于项目的协作式学习,激发学生的学习兴趣及热情,加强英语表达的锻炼,从而保证双语教学的有效开展。     

基于多代理的模糊协同过滤

Automated collaborative filtering has become a popular technique for reducing information overload. We have developed a new method for recommending items using multiple agents. The agents were established by employing the fuzzy C-means clustering technique. We employ these agents collaborating each other to get recommendation for users. The results were evaluated by using MovieLens movie＇s rating data. It is shown that the algorithm is an effective metrics in collaborative filtering.     

Speaking, listening and learning: a rationale for the Speaking and Listening Profile

Schools have often not recognised the basis for literacy that oracy provides, but with the issuing of the recent package for speaking and listening to schools, Speaking, Listening, Learning, the tide is now beginning to turn. However, many schools still have not set up any developmentally sequenced structure for assessment in this strand of English. Realising this need, Dorothy Latham has designed such a profile, based on the criteria given in the official package, but with useful additions, showing clear definitive levelling in an easy‐to‐use format. Schools have been consulted and continue to trial its use.     

制度支持是否促进了产学研协同创新？——企业吸收能力的调节作用和产学研合作紧密度的中介作用

产学研的协同创新需要制度予以支持,而现有研究鲜有从制度支持这一“帮助之手”视角展开探讨。因此,本文依据二分法制度理论,在将制度支持分为正式和非正式制度支持两个维度的基础上,就2010-2016年间中国大陆30个省市区的数据,采用固定效应模型和面板校正标准误方法探究制度支持对产学研协同创新的影响,并考察在这一影响过程中企业吸收能力的调节作用以及产学研合作紧密度的中介作用。研究结果表明,作为“帮助之手”,正式和非正式制度支持均对产学研协同创新有正向影响;企业吸收能力增强了正式制度支持对产学研协同创新的影响,但却减弱了非正式制度支持对产学研协同创新的影响;产学研合作紧密度在正式和非正式制度支持影响产学研协同创新中均起到部分中介作用。本文的研究结果能够为从制度支持视角促进产学研协同创新提出建议,推动产学研协同创新的发展。     

基于灰色关联分析法的跨境电商与物流协同水平测度研究

[目的/意义]研究跨境电商与跨境物流的协同水平,挖掘导致协同水平低的原因。[过程/方法]筛选跨境电商物流复合系统协同水平的初始指标,并设计协同度测量模型,利用灰色关联分析,测算2011—2017年跨境电商物流协同水平。[结果/结论]跨境电商子系统的发展总体向上,跨境物流子系统发展落后于跨境电商子系统;从总体来看,跨境电商与跨境物流协同水平仍不稳定。
