「亞卓鎮」（EduTowns）系統是一個施行於台灣地區，目標為幫助各級學校快速建立線上社群網站的線上社群系統，透過「亞卓鎮」系統的使用，教師與學生們能以輕鬆便捷的方式建立出具基本功能的學校或班級網站。而許多研究指出，客製化策略的實施，能有助於提升使用者的認同感與忠誠度，本篇論文的目的即在「亞卓鎮」系統之上設計與實作出可客製化的機制，能讓使用者在「亞卓鎮」系統內申請的網站進行量身訂作地的修改，以更切合於使用者對於網站使用的需求，並藉此提升使用者對此網站的認同感。 在本篇論文中的可客製化機制規畫上，分別針對具網頁製作與程式設計能力的使用者，設計出 “亞卓鎮佈景系統” 與 “可擴充的網站服務架構” 兩項機制，前者可讓使用者設計出專屬的網站外觀，後者則以 Web Services技術進行實作，可讓使用者自製與擴充所需的特殊站內功能，透過這兩項機制的實施，可讓「亞卓鎮」系統內的班級網站達到量身訂作的效果，而更加落實於 “班班有網站” 此願景的達成。 “EduTowns” system is an online community system implement in Taiwan. The goal of this system is to help schools to establish their online communities rapidly. With the using of "EduTowns" system, teachers and students could build school or class websites that have basic functions in an easy and fast way. Many researches pointed out that the performances of customization strategy could improve the users' identification and loyalty. The purpose of this paper is to design and implement the customizable mechanisms on “EduTowns” system, so users could customize their websites applied from “EduTowns” system, and meet the needs of website-user more appropriately. And it also improves the users' identification for their websites by the same way. In this paper , when planning the customizable mechanisms, we aimed at users who have either homepage-design ability or programming skill, and designed two mechanisms for them respectively: "EduTowns Theme System" and "Extendable Website Services Architecture". The former could let users design their exclusive website appearance, and the latter, which is implemented by Web Services technology, could allow users to make and extend the special website services they need. With the executing of these two mechanisms, we could make the class websites in “EduTowns” system to be customized, therefore approach the vision: “Every class has its own website” closer.
