让英语教学活起来

机械与灵活这一辩证关系贯穿于英语教学的全过程,英语课堂教育就会灵活而不混乱,严谨而不呆板,让学生在一种轻松活泼的气氛中扎扎实实地学习语言掌握语言并最终能够自如地驾驭语言。可以说,机械与灵活,实为外语教学之真谛。     

Citizenship education ‘goes global’: extra-curricular learning in an overseas campus of a British civic university

Active citizenship is increasingly being framed in the context of lifelong and life-wide learning. However, research on young people’s participation in and experience of different forms of civic practice, particularly in informal settings in different sociocultural contexts, is scarce. Consequently, little is known about how these experiences shape their learning about active citizenship, their understanding of the self and their relationship to society. This paper reports findings from a small-scale qualitative research on students’ experiences of participation in extra-curricular activities (ECAs) in a UK Transnational Higher Education institution in China, in relation to the development of active citizenship and lifelong learning capacity. The findings suggest ECAs can provide opportunities for students to accumulate knowledge and develop skills, attitudes and values that underpin the promotion of active citizenship, while developing habits and skills essential for lifelong learning.     

化学教学中情感因素的积极作用和培养

化学学习过程是认知与情感的统一，它们在学习过程中同时发生、交互作用，从不同的角度对学生的发展施以重大影响。没有情感因素的参与，化学学习活动既不能发生也不能维持。情感因素可以优化教学过程．提高学生认知水平，促进学生素质的全面发展；在化学教学活动中，教师要充分重视情感因素，培养学生情感，发挥情感因素的积极作用，提高教学效果，为祖国培养新世纪需要的合格人才。     

负载型催化剂研究中的自发单层分散原理

许多负载型催化剂的活性组分可在载体表面自发分散。当活性组分含量低于其分散阈值时,它在载体表面呈单层但非密置单层分散,逾此阈值时出现晶相。自发分散效应可以称为自发单层分散原理。对自发单层分散原理的实质等问题作了初步探讨。

基于自适应预测算法的APF无差拍控制方法

有源电力滤波器（active power filter, APF）补偿电流跟踪控制要求具有较高的稳态精度和较快的动态响应速度。文章将自适应预测滤波算法应用于无差拍控制,实现APF补偿电流精确控制。根据APF时域数学模型,推导滤波系统的无差拍控制离散方程;通过自适应(finite impulse response filter, FIR)预测滤波算法实现基波电流预测,消除控制系统的计算延迟,给无差拍控制提供所需的指令电流预测值。对预测算法进行MATLAB仿真,验证预测算法的稳态精度和动态跟踪快速性;实验室样机验证控制实验结果证明所提出的控制策略有效的,具有一定的实用性。     

GiveMe Shelter: a people-centred design process for promoting independent inquiry-led learning in engineering

It has become increasingly common for tasks traditionally carried out by engineers to be undertaken by technicians and technologist with access to sophisticated computers and software that can often perform complex calculations that were previously the responsibility of engineers. Not surprisingly, this development raises serious questions about the future role of engineers and the education needed to address these changes in technology as well as emerging priorities from societal to environmental challenges. In response to these challenges, a new design module was created for undergraduate engineering students to design and build temporary shelters for a wide variety of end users from refugees, to the homeless and children. Even though the module provided guidance on principles of design thinking and methods for observing users needs through field studies, the students found it difficult to respond to needs of specific end users but instead focused more on purely technical issues.     

Traffic Light Cards: a Cross and Modification Between the Minute Paper and Muddiest Point

Muddiest point and minute paper have been popular techniques to obtain feedback from students. However, focusing on the muddiest point too often can be discouraging for both students and instructors; in minute paper, students may often have off-topic comments. Here a cross and modified technique, the ‘traffic light’ card is introduced, to overcome the drawbacks in muddiest point and minute paper. About 2?minutes before the end of lecture, students “traffic light” the given topics on a notecard, in which their understanding is high (green), partial (yellow), or low (red). The results are used by the instructors to give appropriate review in the next lecture and help students gain better understanding in the content.     

略论李烈钧的抗日主张

“九·一八”事变后,由于南京国民政府奉行不抵抗政策,日本侵略者气焰更加嚣张。这时李烈钧便提出“开放政权”、“实行民治”、“内部一致”、共同抗日,以及挽救民族危亡的主张,并向政府与蒋介石对日侵略所采取的态度和政策提出了批评。     

英汉广告语篇物质过程结构表达方式对比分析

通过实例对比分析英汉广告语篇小句层面物质过程结构表达方式,发现受英汉语言本体性质及价值、思维趋势的影响,两种语篇中物质小句具有相同的语义成分结构,但构成序列迥异;英语被动物质过程小句呈现出静、动两种态势,汉语被动物质小句只表动作行为,不表状态。
