【摘要】 21世纪是一个以网络为核心的信息时代,信息技术与互联网科技日新月异,并已悄无声息地渗入到人们工作生活的方方面面,同时给教育领域更是带来了前所未有的深刻变革。在教育信息化的推进进程中教师既是重要的组成部分,又是教育信息化建设的重要力量,其数字素养关系着能否适应信息技术的高速发展,真正做教育信息化发展的推动者、实践者,尤其是肩负着我国基础教育的中小学教师,他们的数字素养水平直接影响着一代甚至几代人的发展。目前对于中小学教师数字素养评价的相关理论研究有很多,但切实针对其理论研究开发的评价系统却非常少,所以,建立一个有理论依据的中小学教师数字素养评价系统是非常必要的,不仅能提高研究人员的工作效率,还有利于对收集的数据进行全面科学化分析,从而准确的检测中小学教师数字素养指标的有效性及其数字素养水平现状,帮助建立一套科学化的教师数字素养评价体系,切实提高新时代中小学教师的数字素养水平。本论文着重于中小学教师数字素养评价系统的设计和实现,创新性地将在线测试和分析评价功能集合在一个系统中,并依据同一套评价指标体系,完成了系统在线测试和分析评价功能的设计和实现,为中小学教师数字素养的检测和评价提供了方便。本论文主要从以下几个方面展开研究：(1) 中小学教师数字素养评价理论研究。界定了中小学教师数字素养的内涵,遵循其构建原则建立了教师数字素养评价指标体系,为系统开发提供了理论依据。(2) 系统分析与技术背景。主要分析了系统的功能需求和系统流程,并对开发系统相关的关键技术及自动组卷技术进行了研究,最后确定本系统的结构模式、开发平台和自动组卷策略。(3) 系统总体设计。结合系统的功能需求分析和系统流程分析,主要从系统的结构设计、功能设计、数据库设计三个方面对系统的总体框架进行了设计。(4) 系统的实现与测试。介绍了本系统构建的开发环境及基本功能,展示了系统核心模块的功能实现,并从系统功能、性能和兼容性等方面对系统进行了测试。(5) 总结与展望。主要从理论研究和技术研究两方面对中小学教师数字素养评价系统的设计与实现进行简要总结,分析了取得的成绩与存在的不足,并针对其不足指明了未来的发展方向。更多还原

【Abstract】 The 21st century is an information age that takes the network as the core, IT & internet technology are changing rapidly and have permeated every aspects of our work and our life imperceptibly, e.g. at the same time, education has undergone enormous changes because of the penetration of IT. In the process of advancing ICT in education, teachers play an important role. Their digital literacy relate to whether they can adapt to the rapid development of IT, promoting and fulfilling the goal of supporting ICT in education, especially for Teachers in K-12 education which shoulder the burden of cultivating the young students. Their digital literacy levels have a direct impact on the new generation or even several generations. Nowadays, there are a lot of theories which concern the digital literacy of teachers in K-12 education. However, few evaluation systems rely on the related theories. As a whole, it’s vital to establish an evaluation system which related to digital literacy of teachers in K-12 education. It can not only improve the efficiency of staff, but also benefit to make a comprehensive analysis of the collected data, thus accurately detect indicators and access the status of teachers’digital literacy in K-12 education. In a word, establishing a set of scientific digital literacy evaluation system for teachers’in K-12 education is of urgent need to effectively improve digital literacy of teachers in the new era.This thesis focuses on the research and implementation of the evaluation system for teachers’digital literacy in K-12 education, innovatively integrates online measurement with analysis and assessment in a system based on the same set of evaluation index system The meaning of this thesis is to provide a platform for teacher digital literacy level test and estimation, and makes the way to evaluation more diversified, more scientific and more convenient. The thesis carries out the research from the following aspects:(1) Theoretic research of teachers’digital literacy in K-12 education. First, it defines the denotation of teachers’digital literacy in K-12 education. Second, depending on the theoretic rules to construct the evaluation index system, thus it gives reference for the development of the system.(2) System analysis and Technical background introduction. In this part, the function requirement and system flow have been analyzed in detail. At the same time, key technology for the development of evaluation system and automatic test paper technology have been fully researched. At last, the structure model, platform and strategies of automatic paper-making have been determined.(3) The overall design of system. Coupled with function requirement and system flow analysis, it mainly designs the structure, function, and database, drawing an overall framework of the system.(4) System accomplishment and test. For this part, system development environment and basic function that is accomplished by PHP programming language have been introduced. Second, we display core module function of the system. Then it has been tested from the following aspects:system function, system performance and system compatibility.(5) Summary and outlook. Conclusion has been made concerning the design and accomplishment of the teachers’ digital literacy evaluation system in K-12 education from theoretical research and technology research. Meanwhile, the thesis analyzes the system advantage and disadvantage, and then indicates the trends of future development.更多还原
