1国际化网络协作学习的教学效果——学生视角的质性研究显示文摘国际化网络协作学习(Collaborative Online International Learning,COIL)是一种跨文化虚拟交流模式,它融合了互联网技术、项目式学习和小组协作。本研究对天津某高校大学英语课程与纽约某高校日本艺术与文明课程的COIL项目进行跟踪调研,通过访谈和反思日志收集数据,从中方学生的增能情况、对COIL的态度及建议等角度探讨COIL的人才培养效果。数据分析发现COIL可实现多维增能效果,如提升中方学生的语言技能、非语言技能、自信心和主动性等;中方学生对COIL的态度以积极为主,消极为辅,但也面临着语言、网络工具、数字鸿沟、时差、文化差异、COIL周期、教师指导等方面的困难,有待于从个性化、规范化、常态化的角度完善教学设计,提升学生的学习效果。冯瑞玲 Kyunghee Pyun 2021高教探索2021,,10:5
2Photonic structures in radiative cooling显示文摘Radiative cooling is a passive cooling technology without any energy consumption,compared to conventional cooling technologies that require power sources and dump waste heat into the surroundings.For decades,many radiative cooling studies have been introduced but its applications are mostly restricted to nighttime use only.Recently,the emergence of photonic technologies to achieves daytime radiative cooling overcome the performance limitations.For example,broadband and selective emissions in mid-IR and high reflectance in the solar spectral range have already been demonstrated.This review article discusses the fundamentals of thermodynamic heat transfer that motivates radiative cooling.Several photonic structures such as multilayer,periodical,random;derived from nature,and associated design procedures were thoroughly discussed.Photonic integration with new functionality significantly enhances the effciency of radiative cooling technologies such as colored,transparent,and switchable radiative cooling applications has been developed.The commercial applications such as reducing cooling loads in vehicles,increasing the power generation of solar cells,generating electricity,saving water,and personal thermal regulation are also summarized.Lastly,perspectives on radiative cooling and emerging issues with potential solution strategies are discussed.Minjae Lee Gwansik Kim Yeongju Jung Kyung Rok Pyun Jinwoo Lee Byung-Wook Kim Seung Hwan Ko 2023Light(Science & Applications)2023,12,7:3
