師生互動白板系統

Abstract

目前在網際網路上有多套 web-based 的協同式白板系統 (web-based collaboration whiteboard system)。然而，這些系統在課堂間進行師生教學互動時，仍然有待功能面的增強或改變。例如在使用者角色的功能規劃，需要能夠清礎地將教師及學生區隔開來；又如需要提供一個更好的介面，讓學生能更輕易地與教師進行互動；此外部分白板系統的實作採用 Adobe Flash 技術，使得使用者必須在瀏覽器上安裝一些外掛程式。 因此，本論文將設計並發展一套基於 web、適用於教室教學的協同式白板系統，以利教師與學生的教學互動。這個系統提供教師專用的工具及功能，以建立一個更好的學習環境。此外用戶者端的操作介面以 HTML 及 JavaScript 的方式實作，因而在使用本系統時，使用者不需要在瀏覽器上安裝其他的外掛程式。 在本系統裡，採用 Orbited 伺服器負責應用程式的即時溝通；用 PHP 開發伺服端的應用程式；用 Raphael JavaScript 程式庫建立使用端網頁上的 SVG 圖型元件；用 Prototype JavaScript 程式庫建立用戶者端的應用程式；以及採用 MySQL 當作資料庫。

Nowadays, there are many web-based collaborative whiteboard systems all over the Internet. But, they do not provide functions that support teacher-student interaction in the classroom. Those systems do not clearly divide user’s role into teacher and student and do not have a good interface to support student interaction with lessons and teachers. Moreover, some of those whiteboards are implemented by using Adobe Flash, which needs to be installed as a browser plug-in. Therefore, in this thesis, we design and develop the web-based collaborative system for the classroom, which support the interaction between the teacher and the students. The system provides tools and functions that can be utilized by teacher for creating better learning environment. Besides, the client side is entirely implemented with HTML and javaScript. Therefore, users do not need to install any browser plug-ins in order to use this application. In our system, the orbited server is used for making the application real-time. PHP is used for developing the application on the server side. Raphael javaScript library is used for creating SVG graphic element on the client browser. Prototype javaScript library is used for creating client side application. And, MySQL is used as the content storage.
