【摘要】 当今,人类正在步入一个以智力资源的占有和配置,知识生产、分配和使用为最重要因素的知识经济时代,为适应信息时代的要求,迎接知识经济的挑战,信息素质理应成为21世纪现代化建设人才必备的基本素质,因此,数据库课程已不只是计算机各相关专业的专业核心课程,也已成为许多非计算机专业的必修课程。VFP课程开设的必要性主要体现在三个方面。其一,Visual FoxPro关系数据库系统是小型数据库管理系统的杰出代表,软件虽小巧但五脏俱全、安装方便。通过学习VFP这门课程既可以对数据库基础理论有所了解,也可以学习标准的非结构化查询语句SQL,还可以学习Windows窗口应用程序的基本开发过程,学习表单、报表的使用。其二,VFP是全国计算机二级考试科目之一。其三,我们学校有较强的师资队伍,更应该继续发掘这门课程的潜力,不断改进教学方法,使教学效果更上一层楼。针对我们学校的教学现状,我提出“理论讲解+实践教学+在线自主学习+期末机考”的新的教学方案。通过教学辅助系统,不仅方便教师备课,规范教学制度,统一教师讲课的主干内容,能最大程度地保证教学的有秩序的进行,而且使学生了解课程的整体结构,有的放矢;学生可以充分预习下次课的内容,并且可以对所学知识及时复习,真正做到有目标地学习;学生还可以通过平时有针对性地练习,加强学生对所学知识的理解程度。根据系统需要实现的具体功能,本网络教学辅助系统主要划分为“题库管理”模块、“试卷生成”模块、“在线考试”模块、“在线学习”模块以及“在线答疑”模块。在设计的过程中主要研究在线学习、在线考试、试题与试卷的管理等内容。本系统一共有三种权限访问,系统管理员、教师和学生。系统管理员拥有题库管理、用户管理、在线答疑模块管理和期末试卷管理等功能,教师用户拥有在线学习、在线练习、作业管理、在线答疑、学生管理等功能,学生用户拥有在线学习、在线考试、作业、在线答疑等功能,系统管理员还可以根据工作需要为教师用户分配指定的权限,如向题库中添加指定知识点的试题,以增加教师之间协同工作。本系统是采用Microsoft Visual Studio 2010开发平台,SQL Server2008数据库系统,选用VB.NET语言基于.NET Framework4.0开发的网络教学辅助系统。更多还原

【Abstract】 Today, human is stepping into an economy era in which the most important factors are occupies and configuration of intelligence resources and knowledge production, distribution and using. In order to adapt the requirements of information era and meet the challenge of knowledge, information quality should become the basic quality of 21st century modernization construction talent. Therefore, database courses are not only core courses of computer major and also have become compulsory courses of profession.Necessity of VFP courses mainly reflected in the three areas: first, Visual FoxPro relational database is an outstanding representative of small database management system. The software is small, but there is everything and it is convenient to install. By learning VFP, you can understand the basic theories of database and also learn standard unstructured SQL, basic development process of Windows applications of Windows, forms, and the use of report. Second, VFP is one of the subjects of national computer exams. Third, because our college has excellent teaching staff, we esp. should continue to explore the potential of this course, improve teaching methods and then promote teaching effect.According to the teaching situation of our college, I made a new teaching plan of“classroom-based theory explanation + LAN-based experiment teaching + Web-based autonomous learning+ final exam on computer”. Through teaching auxiliary system, it is not only convenient to prepare for teachers, specify teaching system, unify trunk content of teachers’lectures, guarantee teaching order in the maximum extent, but makes students understand the overall structure of the course and shoot the arrow at the target; students can full preview the content of next class, review the knowledge they have learned timely and really realize learning with purpose; students also can strengthen understanding of knowledge they have learned by their everyday targeted exercises.Depending on the specific function the system need to come true, this network teaching auxiliary system is mainly divided into”paper management”module、”test building”module、”online test”module、”online learning” module and“online answering”module. In the process of design, what is main is to research online learning, online test, the management of test questions and test papers and so on. There are three types of access to this system: system administrators, teachers and students. System administrator has the function including test bank management, user management, and online answering module management and final papers management. Teachers user has online learning, online contact, assignment management, online answering, and students management. Students user has online learning, online test, assignment, online answering. System administrator also can distribute specified permission as needed, for example, to add test bank with specified knowledge points in order to increase the cooperation between teachers.The system is a network teaching auxiliary system which adopts the Microsoft Visual Studio 2010 development platform, SQL Server 2008 database system, and VB.NET language and is based on NET Framework4.0 to develop.更多还原
