The purposes of this study were (1)to investigate status quo of cochlear implant children; (2)to survey attitudes and concerns of students, parents and teachers toward cochlear implant. 825 hearing impaired (HI) students (from grade 7-12 high schools for the deaf) and 1,419 HI students (from grade 4-9 in HI classes) were chosen as samples. 2,997 parents and 528 teachers (at grade k-12 levels in special schools and classes for the deaf) were also included as the samples. In this study, three kinds of questionnaires were then main instruments. Of them, 1,263 student questionnaires were answered. It resulted in a 56.3% returning rate. Of 2,997 parental questionnaires, 1,836 were returned. This produced a 61.3% parental returning rate. Of 528 teacher questionnaires, 328 were answered (the returning rate was 58.8%). The frequency distribution and a percentage were used as statistic method for analyzing data. Chi square test was used for testing different results among those three kinds of samples. The researcher made conclusions based on subjects' data of accepting cochlear implant status and parents'/ teachers' attitudes toward cochlear implant. Finally, some suggestions for further study and rehabilitations concerning speech and auditory training after cochlear implant operations were recommended.
