To compare the effectiveness of unisensory (auditory) and bisensory (auditory-visual) based language training methods on auditory perception and expressive language skills in Persian cochlear implanted children
In this study, we will compare the effectiveness of auditory and auditory-visual based language training methods on auditory perception and expressive language skills in Persian cochlear implanted children. We have assumed that if we focus on auditory modality to educate the cochlear implanted children, they can learn more effectively and efficiently auditory perception and language skills. We need to design and prepare two language training protocols to examine the hypothesis. The sensory modality will be the only difference between the protocols. We will use principles and technics of auditory-verbal and aural-oral approaches in the protocols.
