| The EPSS (Electronic Performance Support System) is a kind of electronic tool which is paid close attention to by business circles relatively, and it can help train staff, raise productivity, improve performance of working, bring about an advance in enterprise. It emerged in the job-training field at first, and obtained enormous success among the enterprises. In recent years, it has some application too in education system of oversea school. The EPSS, developed by educators through combining the characteristics of the multimedia computer and internet, is used for promoting the learners' information obtaining and helping the school administrative personnel deal with teaching relevant jobs, and demonstrates the merits, such as fast, prompt interaction, etc. And the EPSS research becomes a new trend today.This paper presents the concept of performance and performance technology in detail. And it also discusses the concept, components and characteristics of the EPSS (Electronic Performance Support System) at length. At the same time, this paper details the concept of educational performance and the connection relate to the EPSS. Besides, this thesis is talking of the teaching characteristics of elementary school and high school's course of information technology and its teaching goals for conforming the advantage and necessary of using performance technology to develop the EPSS. After recommending the status quo of the EPSS at home and abroad simply, we put the task-based learning theory forward as our system's sustaining theory.By the knowledge about system design and database design, we design the whole system in detail and the layout of the background database. In our designing, we make use of a lot of module chart, flow chart and E-R chart for the sake of expressing our design thinking clearly. Besides the logic design, we also divide our system into two parts-background database and forward user's interface, and detail the technology design of the two parts respectively. |
