| Summary: | 碩士 === 國立花蓮教育大學 === 身心障礙與輔助科技研究所 === 95 === This study had four goals: 1. to investigate the effectiveness of recognition phonic symbols in different teaching methods, 2. to investigate the effectiveness of speak out phonic symbols in different teaching methods, 3. to compare the three computer input devices for the subject, and 4. to investigate the effectiveness of computer input training.
The research method of the study used single subject serial reversal-replication experimental design for the goal #1 and #2 and used single-case [embedded] design for the goal #3 and #4 as mentioned. The subject of the study was a female adult with cerebral palsy and she was an illiterate person. The researcher spent nine weeks to finish this study. According to the results of the study findings were as follows:
1. For the subject, all three Chinese phonic symbols’ teaching methods were useful in recognition and speak out effects. But when using meaningful Chinese phonic symbols’ teaching method, the data paths had better trend and more stable. The data path of traditional Chinese phonic symbols’ teaching method was less stable. When using the meaningful Chinese phonic symbols’ teaching method, the learning effectiveness in recognition phonic symbols was better then speaks out phonic symbols.
2. The best angle for the subject to operate the computer input device was 45 degrees. Both keyboard and keyboard with key-guard should enlarge Chinese phonic symbols’ font size on each cell. In addition, screen keyboard also needed to enlarge both Chinese phonic symbols’ font size and key button size, as well as needed to remove unnecessary button on the screen keyboard. In the consideration of the accuracy rate, the researcher selected touch screen with screen keyboard as the subject’s computer input device.
3. In the training how to operate computer input device, one should consider three factors: first, when the subject operated a computer input device, her position should be always in the same spot; second, the assistant must moved her right arm to the front of her body; finally, the subject’s right arm would block her vision, if she suddenly raised her right hand.
After the research finished training the subject how to recognize all of Chinese phonic symbols, the subject’s computer input accuracy rate was also increased.
