Challenges and possibilities in climate change education

Educating and communicating about climate change is challenging. Researchers reported that climate change concepts are often misunderstood. Some people do not believe that climate change will have impacts on their own life. Other challenges may include people＇s difficulty in perceiving small or gradual environmental changes, the fact that overconsumption brings people power and recognition, people＇s weak connection to nature, and people＇s tendency to make emotional decisions and quickly solve environmental problems. Drawn from research, some climate change communication and education strategies are presented. Well designed environmental messages could convince people that they can still reduce the scale of the phenomenon and could link mitigation actions to people＇s positive desires or aspirations, while providing local examples of climate change impacts and illustrated information. In mitigation education, some strategies （future education, reflective, experiential, socio-constructivist approaches and the community of change）, jointly used, could correct the learners＇ misconceptions and lead them to action. In adaptation education, scientists and citizens could get together to choose a specific problem that may worsen with climate change, analyze it, and propose and implement adaptations. In the meantime, pedagogical strategies inspired by cognitive science could strengthen the citizens＇ skills： posing and solving problems, decision-making, scenario building and sustainable planning.     

汉英散文翻译中显性与隐性逻辑连接的转换

逻辑连接是语篇衔接的重要手段,汉英篇章使用的连接词不同,汉语以隐性连接为主,英语呈显性。翻译中处理显隐性翻译的转换是翻译研究的热点之一。在对比汉英散文中逻辑连接的基础上,对其在汉英翻译中的隐性向显性的转换进行了分析思考,考察实际中的处理方法。     

含电表电路的等效电路

1．含电流表的电路把电流表看做导线（因为电流表的内部电阻很小,可以把它看做电阻为零的导线）,分析其它元件的连接情况,画出等效电路的草图,最后把电流表连接到相应的位置．     

分压式电路中滑动变阻器的选择

滑动变阻器是电学实验中常用的器材,它在电路中的连接方式是中学物理实验教学的难点,也是历年高考的一个重要考点。滑动变阻器在电路中的连接方式有两种,一种是限流式接法（如图1a）,

连接主义视角下社会性软件用于学习的思考

Siemens的连接主义是数字时代的创新学习理论,本文首先介绍了Siemens对学习的主要看法,连接主义的8个原则,并对连接主义的主要内容和观点进行了简要描述。接下来,在连接主义的理论指导下,文中从网络化模型视角,连接性视角,外部性视角,社会形视角,网络生态学视角和流通性视角,对社会性软件用于学习进行了探讨。然后比较行为主义,认知主义,建构主义和连接主义对社会性软件用于学习的指导作用,由此得出,连接主义更适合作为将社会性软件用于学习的理论依据。
