YANG Junfeng  SHI Gaojun  ZHUANG Rongxia  WANG Yunwu  HUANG Ronghuai 《Frontiers of Education in China》2022,17(4):490

The 5G communication technology serving a wide range of vertical industries is maturing, which provides a possible boost for the development of smart education and lays a foundation for solving the principal contradiction in current education. With the characteristics of ultra-high speed, low latency, low energy consumption, massive network capacity, and high reliability, the 5G technology is applied with other technologies like artificial intelligence (AI), internet of things (IoT), big data, and blockchain to promote the application upgrading of intelligent education technology. This paper analyzes the intelligent education technology and its eight typical applications in the 5G era, which include smart safe campus, integrated learning spaces, synchronous cyber classrooms, teachers’ professional development, robot learning partners, mobile and ubiquitous learning, virtual simulation training, and smart e-textbooks. Then, it discusses how intelligent education technology promotes changes in the modes of learning and teaching in the 5G era from three dimensions: individual learning, collaborative group learning, and classroom-based collective teaching. At last, the framework of smart education in the 5G era is proposed from the perspectives of intelligent education technology and its typical applications, changes in learning and teaching, and the new ecosystem of smart education.  相似文献

The Effect on Enhancing Students＇ Inquiry Abilities via Step-by-Step Open-ended Inquiry Teaching Design     

Chung-Ming Yang  ;Jeng-Fung Hung  ;Tai-Chu Huang 《美中教育评论》2014,(12):887-894

The purpose of this study is to promote more open-ended inquiry activities in junior high school science lessons in the current educational system with fixed textbooks. Researchers adapted existing curriculum-based experimental activities for more open-ended inquiry ones. In addition, the whole class was provided with more opportunities to explore complete activities in limited teaching time. This study used Hazel＇s proposals of levels of inquiry. The method was to carry out the current 8th grade experiments through the step-by-step teaching material modification （from levels of inquiry 0 to 2b） and to combine the experimental teaching method with the 5E （engage, explore, explain, elaborate, and evaluate） learning cycle. After a quasi-experimental study, we compared the traditional teaching method with the step-by-step open-ended inquiry teaching one on 8th graders＇ basic and integrated science process skills and academic achievements. The study result showed that the academic achievement in the experimental group, based on the same instructional time, was not worse than that in the control group. No significant difference was found on the total scores of the basic science process skills between the two groups, but a significant difference was found on the ＂predicting＂ dimension. There was a significant difference on the total scores of the integrated science process skills between the two groups. Significant differences were found on ＂interpreting data＂ as well as ＂experiment designing＂ dimensions. Hence, the study indicated that it could enhance students＇ inquiry ability through step-by-step openly inquiry levels to change the existing curricula, which served as a reference of educational reform.  相似文献

中世纪英国货币流变与政治经济变迁初探     

崔洪健 《海南师范大学学报(社会科学版)》2014,(4):96-102

在罗马帝国的货币制度和欧洲大陆货币流变的影响下,中世纪早期(5-8世纪)英国的货币经历了对罗马帝国铜币的仿造→金币特里姆萨→银锡特→银便士的流变过程,最终选择铸造银便士。中世纪早期英国货币的流变不仅反映了当时政治经济变迁,而且也体现了货币在社会发展中的推动作用。  相似文献

译员对工作语言“语言特质”掌握程度对口译过程的影响     

严璐 《乐山师范学院学报》2014,(9):43-49

语言思维认知观认为,语言与思维关系密切,但并非同源产生、平行发展。语言习得过程中,思维塑造语言,而语言则影响和部分构建某些思维;语言使用过程中,二者关系愈加密切,但仍存在着无需语言外壳的思维。不同的自然语言语符系统不仅在韵律、词语、句法、篇章结构等方面呈现为各异的语言形式,还蕴含着各自民族的思维方式、社会文化特色及其发展阶段,这些要素构成了一门语言的"语言特质"(le génie de la langue)。文章通过梳理和厘清"语言特质"这一概念,从而推测不同水平译员对工作语言的语言特质的掌握程度会影响他们在口译过程三阶段(理解、转换、产出)中对语言形式的处理程度和信息传达效果。  相似文献
