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

本研究的目的是开发一种集黑板教学的互动性和信息处理的优势于一体的交互式电子白板信息技术与信息处理教学软件。研究结果如下：1.我们开发了以下教育软件：数学函数教育软件，识别手写公式并精确绘制其函数，并显示切线，局部最小值和局部最大值。电子电路教育软件，显示由电池，电阻器，开关，灯等组成的给定电路的电流模拟，满足基尔霍夫规则。浏览器，识别手写关键字并搜索与关键字相关的WWW站点。单词教育软件，识别手写单词并显示如何写它们，如何读它们，它们的同义词等。编程教育软件，识别手写程序，编译并在电子白板上执行。然后，我们制作了以下原型：演讲传递系统，将电子白板上的手写内容传递到通过Internet连接的计算机。手写被作为笔坐标的序列发送，而教师的图像被从她/他的手写位置和站立位置组成为化身，以便免除她/他的图像的传输。语音传输还没有实现。协作支持系统，以准备学校报纸的材料是由笔PC的，他们是在电子白板上。我们编制了设计指南，以开发电子白板的教育软件。

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.
