Multi-media CAI and its authoring system for mental handicapped humans

本研究开发了一种易于操作的多媒体计算机辅助教学（CAI）软件，以提高智障人士的积极态度、注意力和学习动机，以触摸屏为输入装置，以图形动画为输出装置，制作出一种方便智障人士使用的软件。并制作了一个适合残疾学生个体水平的CAL课件制作系统。总结了弱智学校学生使用该课件的实验结果。智障人士经常无法使用传统的CAI，因为他们很难理解即使是简单的句子，也很难输入软件。在本研究中，采用了触摸屏和动画技术，因为它们可以很容易地实现对CAI软件的响应。实现了几种类型的CAL课件。学习实验结果表明，CAL课件对大多数学生的学习效果良好。特别是在触摸屏上的拖拽式输入和图形动画的方法对学生提高注意力和学习动机非常有用。并对教师可使用的课件制作系统进行了详细的开发和描述。由于课件制作系统只需要在菜单项中选择一项即可生成cai课件，因此教师可以方便地制作出适合个别学生残疾水平的课件。

This study develops the easy operating Multi-media computer Assisted Instruction (CAI) software for mental handicapped humans in order to increase positive attitude, concentration and motivation to learn, By using Touch Screen as an input devise and graphic animations as an output, we can produce the software that mental handicapped human can use easily. And we make an authoring system to produce the CAL courseware suitable for handicapped level of the individual student. The results of experiments that students of the mental handicapped human's school use the courseware are summarized.Mental handicapped humans often fail to use the conventional CAI, because it is hard for them to understand even simple sentence and how to input for the software. In this research, a touch screen and animation technique is employed, because they can easily realize how to respond to the CAI software. Several types of CAL courseware are implemented. The results of learning experiments show that the CAL courseware works well for the most of them. Especially the method of drag type input on the touch screen and graphic animations are very useful for the students to increase concentration and motivation to learn.The authoring system that teachers are able to use is also developed and described in detail, Because the authoring system produces the CAl courseware only by selecting one of menu items, the teachers can easily make a courseware suitable for handicapped level of the individual students.
