Another problem was that even assembling the students could take 10 minutes. In the case of normal students it is only necessary for a teacher to call them by speaking more loudly or using a microphone. The attention of handicapped students, however, must be attracted visually by using sign language.
在教學的過程中，當然不免有好多不如意的事，比方說，如果要集合學生練習，在普通學校裡，用擴音機可以在五分鐘內達到目的，可是，在他們的學校裡就不成了，老師得一間間教室去找，用手語一遍遍去「說」，這真是很累人的事。
