Understanding L2 French teaching strategies in a non-target language classroom context

This research explored the congruence and disparity between teachers’ and students’ attitudes towards French as a second language (L2) teaching strategies in a non-target language classroom context in the USA. The findings suggest students’ and teachers’ attitudes towards the direct and indirect teaching strategies were generally consistent, but not in terms of the collaborative teaching strategies. The findings also indicate that the beginner and elementary level students held different preferences for all the three teaching strategies. The underlying reasons could be learners’ different language proficiency levels, and how well teachers execute these different teaching strategies in class. This study concludes with some implications for foreign language teacher education.     

社区治理视角下的学习型社区建设路径探析——以郑州市为例

学习型社区建设既是学习型社会建设的重要途径,也是推进社区治理体系建设的重要发力点。当前,全国各地都在大力发展社区教育,推进学习型社区建设,但也存在管理体制和运行机制不完善、多元参与不够、资源整合能力不足、信息化水平不高、融入社区治理程度不够等问题。在总结郑州市学习型社区建设经验基础上,从社区治理的视角提出,要进一步完善学习型社区建设体制机制,加强顶层设计,强化督导评估,开展学习共同体创建,培育终身学习文化、提升信息化学习水平,形成党建引领、多元参与、协同治理的学习型社区建设工作格局。

教育现象学对高等教育研究的方法论价值

教育现象学追问生活世界中具体的教育现象,是对教育问题的直观和审视.高等教育研究在形成多学科研究观点的过程中,其研究方法也可以从教育现象学中吸取养料.在高等教育研究中,从教育现象学的视角,应注重研究回到实事本身,回到生活世界,进行问题反思.     

CB/EDACUM模式在行业英语教学中的运用

为探索在高职院校行业英语教学中采用DACUM模式能否帮助学生更熟练地掌握专业英语知识,将参加本次实验的学生分为实验组和对照组,参照组采用传统的语言技能讲授法,实验组采用CBE/DACUM模式进行教学。结果显示：实验组通过采用CBE/DACUM模式进行教学后专业英语成绩提高显著优于对照组（P〈0.05）。由此得出结论：在行业英语教学中采用DACUM模式可以帮助学生更熟练地掌握专业英语知识,及更有效地、合乎职业规范地、流利地运用英语进行交际。     

社会经济发展对铜矿资源勘查驱动传导机制分析

定量描述铜矿勘查经济过程并预测其走向,是实现铜矿勘查形势中长期预测、制定铜矿勘查发展战略的重要基础。基于经济发展对铜矿勘查影响传导链,通过文献综述与数据分析,从经济发展对铜消费需求影响、铜供需对其价格影响、铜价格对铜矿开发影响、铜矿开发对铜矿勘查影响等4个环节,分析了经济因素变化对铜矿勘查的驱动机制。分析表明,铜消费与工业化水平紧密相关,世界工业产业迁移以及产业结构变化将对中国铜消费产生深远的影响;中长期铜金属价格随供需变化呈现交替上升与下行的周期性变化,下一轮铜价格上升波次来临取决于接替中国启动工业化的国家;矿产铜生产通常滞后于铜需求和价格变化,铜矿勘查的经济收益受制于铜矿的开发利用;铜矿企业根据全球工业产业格局与铜价格中长期变化制定相应的勘查开采计划,是平稳度过矿业下行期的重要基础。铜矿勘查是一项高风险市场行为,政策稳定、市场透明、可以预期的友好投资环境,对于铜矿勘查企业生存发展至关重要。     

Optimal control of nonlinear switched system in an uncoupled microbial fed-batch fermentation process

The bio-dissimilation of glycerol to 1,3-propanediol (1,3-PD) is a complex bioprocess due to the multiple inhibitions of substrate and products onto the cell growth. In consideration of both the inhibition mechanisms of 3-hydroxypropionaldehyde (3-HPA) and the transport modes of glycerol and 1,3-PD across the cell membrane, we establish a novel switched system which is represented by a ten-dimensional nonlinear dynamical equation containing both extracellular and intracellular environments. The uncoupled microbial fed-batch fermentation process are modeled using the switched system which the glycerol and alkali are respectively poured into. Taking the feeding rates of glycerol and alkali, the switching times and the mode sequence as the control variables, an optimal control model is proposed with the concentration of the terminal time 1,3-PD as performance index. In order to maximize the yield of 1,3-PD, the control parameterization technique and the exact penalty function method are used to solve the considered problem. Numerical results show that under the obtained optimal feeding rates of glycerol and alkali, switching times and mode sequence, the productivity of 1,3-PD at the terminal time is increased significantly compared with previous results.
