The Design And Realization Of Automatic Generating Online Preparing Lessons System Based On Task-Driven Teaching Mode

Since entering the information age, the internet is profoundly and rapidly changing our life, work and study. China is now in the stage of the obvious contradiction between the supply and demand of education, serious shortage of educational software, shortage of teacher resources, and the number of learner is growing rapidly year by year. Teaching on internet has become the focus of the community, and online preparing lesson becomes its basis and key. Nowadays, most online preparing lessons systems are powerful on technical realization, lack of practicability, not integrating instruction mode or instruction theory into internet technology. Almost all online preparing lessons systems stack resources only, played a resource database functions, lacking supporting for the entire lesson preparing process for teachers.Based on the above, the research tries to put task-driven teaching mode in system' s design in order to solve the demand of online preparing lessons. The main content includes:(1)The paper explains the necessity of developing online preparing lessons systems by analyzing the development present situation and the development trend. On the base of a comparative analysis of some typical online teaching platforms and online preparing lessons systems, we put task-driven teaching mode in the system' s design, emerged with the features of online preparing lessons systems and the software engineering sense, the paper emphasizes on the design idea, the general structure and function, realizing method and technology of online preparing lessons systems.(2)On functional realization, the platform considers multidisciplinary characteristics and needs of teachers, meets the needs of the multidisciplinary lesson preparing, from the basic disciplines restrictions, and with high universality. In details, the system includes following features:①Automatic Generating: teaching contents born in the form of web page and online learning process auto-generating.②Supporting interface personal design and process modeling design.③Integrating online preparing lessons with online learning.④With diverse teachers' knowledge management tools, e. g. personal files collecting online, teaching Blog and teachers' Wiki.⑤Multi-level privilege configuration, such as multilevel user' s authority and management.⑥The recording of the process of teachers' online preparing lessons provides the basis for teachers' evaluation.⑦With universal teaching and simple operation. ? Extensibility: extensible teaching model, multi-channel of resource expansion and rich of function modules.(3)The technical realization of the system is the current mainstream of website development technology. Using three Browse/Server structure systems, realized thin-client; based on ASP. NET programming Language, embodies object-oriented programming; using ADO. NET resource database and database tools, makes the system operating conveniently, and SQL Server 2005 Web database Management system. All these technologies guarantee the system' s simplicity, extensibility, security and stability.(4)The platform was tried many times in our teaching practice, by analyzing the application effect, the result shows it is stable, strongly practicable, can still solve the current application demand.In the end, the article summarized the study and made a further study-of the future direction.
