【摘要】：随着教育信息化的迅速发展,网络教学资源建设成为远程教育发展的核心要素,它直接决定着远程教育的质量。《生命科学导论》作为一门基础课,课程内容丰富,学科交叉性强,系统地学习起来有一定难度。建设与其相关的网络教学资源,为学生提供远程学习和师生之间的交流互动,有助于提高教学质量。以课程内容为研究对象,根据课程特点和系统需求,采用Microsoft Access、Dreamweaver、ASP、iSpring、Flash和Photoshop为主要开发工具,研发该课程的网络教学资源平台。采用基于数据库的方式统一存取课件、图片、动画、视频、扩展专题和习题6类教学资源,以便资源数据的及时更新。利用目录树及列表方式搭建课件、图片和动画资源的组织结构,便于学生从整体上建立知识体系。应用嵌入式Iframe技术实现课件的在线浏览,同时保持了PPT模式设置的动态效果。站内搜索功能实现教学资源的快速定位。对于大量的教学图片,提供分页浏览方式。采用流媒体技术使动画和视频资源无需下载,直接在线播放。采用DIV+CSS构造学习交流论坛、在线考试、学习指南和最新公告等教学支撑环境,提供辅导答疑、自主测试、教学计划和信息发布等服务。实践表明:数据维护方便,教学资源丰富,内容表现形象,教学环境实用,为该课程的教与学建立了一个具有稳定性、开放性、共享性、可扩展性和自主性的教学平台。
[Abstract]:With the rapid development of education information, the construction of network teaching resources has become the core element of the development of distance education, which directly determines the quality of distance education. As a basic course, the content of the course is rich. Cross-disciplinary strong, systematic learning has a certain degree of difficulty. It is helpful to improve the quality of teaching by constructing network teaching resources and providing students with distance learning and interaction between teachers and students. Taking the course content as the research object, according to the characteristics of the course and the system demand, the author develops the network teaching resource platform of the course by using Microsoft access, Dreamweaver, ASPII Spring Flash and Photoshop as the main development tools. In order to update the data of courseware, picture, animation, video, extended topic and exercise, the database is used to access the courseware, picture, animation, video and other teaching resources in a unified way. It is convenient for students to set up knowledge system by using directory tree and list method to set up the organization structure of courseware, picture and animation resources. The embedded Iframe technology is used to realize the online browsing of courseware, and the dynamic effect of PPT mode setting is maintained at the same time. The search function in the station realizes the quick localization of teaching resources. For a large number of teaching pictures, provide pagination browsing. Using streaming media technology, animation and video resources do not need to download, direct online play. DIV CSS is used to construct the learning exchange forum, online examination, study guide and the latest announcement, etc., which provides the services of tutoring and answering questions, independent testing, teaching plan and information publishing. The practice shows that the data maintenance is convenient, the teaching resources are abundant, the content shows the image, the teaching environment is practical, and a teaching platform with stability, openness, sharing, extensibility and autonomy is established for the teaching and learning of the course.
