中文摘要 | 長期以來,國內視覺障礙學生(視障生)的數學程度普遍落後於明眼學生,以大學聯招為例,視障生考取數理科系的比率偏低,究其原因,可能與使用的學習資源欠缺有關。本研究將數學教科書以數位無障礙資訊系統(Digital AccessibleInformation SYstem, DAISY)標準製作,輔以使用Adaptive Multimedia InformationSystem(AMIS)及非視覺化的螢幕報讀軟體(Non-Visual Desktop Access, NVDA)輔具,讓視障生能透過 DAISY 讀本進行數學學習,初步先藉由問卷和訪談了解視障生在數學學習時所遇到的問題,接著規劃實驗課程並進行評量DAISY讀本的學習方式對視障生的數學學習成效是否有正向幫助。本研究針對12位視障生施以實驗課程,採使用性評量方法,於課程前後藉由主觀量表蒐集受試者之心智負荷程度,並於課後進行客觀評量。實驗結果顯示,視障生使用DAISY讀本學習的心智負荷程度低於點字課本,在客觀評量中,使用DAISY讀本的答題正確率高於使用點字課本的正確率。整體而言,研究結果顯示使用DAISY讀本數位學習對視障生的數學學習確有明顯助益。 |
英文摘要 | In general, the academic performance of visually impaired students in mathematics is below average. This is due to, in part, the instructional materials, assistive tools, and teaching methods not being designed to meet the special needs of the individual student. For this study, we used questionnaires to access the learning problems of visually impaired students in their mathematics learning. With this information, we produced instructional mathematics textbooks using the Digital Accessible Information SYstem (DAISY) full-text format and the DAISY book can be played on the AMIS reader. A preliminary investigation was then carried out to investigate whether or not the DAISY mathematical textbooks enhanced the reading skills of the visually impaired students. In this research, there were 12 students, grades 7-9, who were provided four days’ course using the DAISY book. The NASA-TLX subjective scales were collected from the students pre- and post-course. The time to answer each question and the percentage of correct answers (using objective assessments) was collected at the end of the course. The results showed that the DAISY textbook provided a better reading format for the visually impaired students as compared with mathematics textbooks in Braille. |
