個別化設計三維列印電腦鍵盤對國中特殊需求學生打字功能介入之成效

The Effects of Applying Individualized 3D Printing Keyboard to Improve the Typing Skills of Junior High School Students with Special Needs

三維列印技術近年來蔚為風潮，常被使用在各個不同的領域。學習障礙學生可能受到識字、書寫困難及知覺動作不佳而影響書寫表現，因此提供電腦打字服務。特殊需求學生使用電腦鍵盤打字容易出現同時按兩個鍵、重複按鍵、鍵盤不合適等情況，研究目的在於透過三維列印輔助科技設計個別化鍵盤，並探討其介入電腦打字之成效。研究採用行動研究法設計，以一名國中學習障礙學生為對象。研究方法使用「交替處理實驗設計」中B、C兩階段分析鍵盤介入後打字功能改善情形。而研究對象一週接受3次評量，共12週。以電腦打字速度及正確度為評量標準，進行行動研究設計與分析。結論使用三維列印技術對國中學習障礙學生之個別化設計電腦鍵盤具有可行性，能部分提升電腦打字速率與正確率，期望三維列印技術運用到更多教學現場。

3D printing technology has become a trend in recent years and is often used in various fields. Some students who have learning disabilities are affected by their literacy, handwriting difficulty, and poor sensory motor skills, so they are provided with assistive computer typing services. Some studies have revealed that while typing on a regular computer keyboard, subjects often press two keys at the same time, press the same keys more than once, and find the keyboard unsuitable. Therefore, the purpose of this study is to investigate the effects of typing skills for subjects with learning disability using an individualized computer keyboard with 3D printing technology. The research is to improve the subject's typing performance through the individualized 3D printing keyboard. The research is conducted in the way of action research approach. The research subject is a junior high school student with learning disabilities. The research uses the alternating treatments method to observe the improvement of the subject's typing skills after using the 3D printing keyboard. The subject was evaluated three times a week, and the evaluation lasted ten weeks. The evaluation standard is the subject's typing speed and typing accuracy. Data analysis was conducted by action research approach, also supplemented by interviews and questionnaires in order to understand the subject's feelings and satisfaction. The conclusions are as follows: 1. It is feasible to apply 3D printing technology in the individualized computer keyboard for students with learning disabilities in junior high schools. 2. The individualized 3D printing computer keyboard can partly enhance the typing speed of students with learning disabilities in junior high schools. 3. The individualized 3D printing computer keyboard can partly enhance the typing accuracy of students with learning disabilities in junior high schools. This research explains and analyzes the research results, and provides relevant suggestions for future research. It is expected that 3D printing technology will be used in more and more schools.
