Prototyping of eye-gathering educational software for Information Technology and Information Processing education as well as formalization of its engineering methodology

本研究的目的是在交互式电子白板上开发信息技术与信息处理教育的聚眼式教学软件，将黑板教学的互动性与信息处理的效益结合起来。取得了以下成果：1.我们开发了以下教育软件：识别手写公式并精确绘制函数并显示切线、局部极小值和局部极大值的数学函数教育软件；满足基尔霍夫规则的显示由电池、电阻、开关、灯等组成的给定电路的电流模拟的电子电路教育软件；识别手写关键字并搜索与关键字相关的WWW站点的浏览器；识别手写单词并显示如何书写、如何阅读它们、它们的同义词等的单词教育软件。识别手写程序并在电子白板上编译和执行的编程教育软件。然后，我们制作了以下原型：授课系统，将电子白板上的手写内容传递给通过互联网连接的计算机。笔迹被作为笔坐标序列发送，而教师的图像被制成来自她/他的手写位置和站立位置的化身，以便省去她/他的图像的传输。没有实现语音传输。制作校报的协作支持系统，通过该系统在笔式PC上准备材料，并在电子白板上布局。我们已经编制了开发电子白板教育软件的设计指南。

This research has aimed to develop eye-gathering educational software for Information Technology and Information Processing education on interactive electronic whiteboards that can combine the interactivity of education using blackboards and the benefit of information processing. The following results have been achieved.1. We have developed the following educational software :Mathematical function education software that recognize a handwritten formula and draw its function precisely and show tangential lines, local minima and local maxima.Electronic circuit education software that shows current simulation for a given circuit composed of batteries, resistors, switches, lights and so on with the Kirchhoff rule satisfied.Browser that recognizes handwritten keywords and search for WWW sites related to the keywords.Words education software that recognizes handwritten words and shows how to write them, how to read them, their synonyms and so on.Programming education software that recognize a handwritten program, and compile it and execute it on electronic whiteboards.2. Then, we made the following prototypes :Lecture delivering system that delivers handwriting on electronic whiteboards to computers connected by the Internet. Handwriting is sent as a sequence of pen coordinates while the image of a teacher is made up as an avatar from her/his handwriting position and standing position in order to dispense with the transmission of her/his image. Speech transmission has not been implemented.Collaboration support system to prepare school newspaper by which materials are prepared on pen PC's and they are laid out on electronic whiteboards.3. We have compiled design guidelines to develop educational software for electronic whiteboards.
