冯永亮 《西安文理学院学报》2014,(3):66-69

随着互联网信息量的迅猛增长,以及B/S架构的应用逐步深入,服务器端存储数据的压力越来越大,传统的Cookies方式已显得力不从心.HTML5通过两种方式:Web Storage和Web SQL Database将一些数据存储在本地客户机,避免了服务器存储容量和网络传送带宽的限制,同时也可以存储较大容量的数据,从而支持网络应用程序的推广和应用.  相似文献   

新世纪美国文科教育改革的概念取向与实践路径——基于希拉姆学院"新文科"(NLA)计划实施意况的案例分析     

浦晗 《黑龙江高教研究》2022,(1):61-68

美国希拉姆学院在2017年推出的"新文科"计划,在论证环节基于迪克森"优先性"标准,在概念中突出"现代性"与"实用性",以未来职业与现实生活的需要为导向,总体结构包含"希拉姆链接"与"技术与远游"两个主要构成项目。前者围绕着"5C"的自我反思,形塑了一套综合性跨学科集群的聚集型专业模式与"主题"分类式的核心连贯课程群,在高影响力的活动中培养实用的技能和系统设计思维;后者以信息化为手段,将科技植入学习的整体过程,强调数字能力的熟练掌握与"数字素质"的科学养成,同时通过技术手段强化实践活动,辅之以"正念"干预平衡信息的过载,最终实现身体、思想与能力的全面提升。这一文科改革计划不仅是21世纪美国文理学院文科教育改革的典范和缩影,还可以为我国当前的"新文科"建设提供借鉴意义。  相似文献

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
