Abstract:

In this research , it is presented an intervention program that combines storytelling with morphosyntactic activities to improve grammatical skills in pupils with Specific Language Impairment ( SLI ) . The sample consisted of a total of 34 pupils diagnosed with SLI and 34 children with typical language development . For the selection of the sample , the CELF - 3 test , the Peabody test , the Hearing Association and Visual Association subtests of the ITPA and the K - BIT Intelligence test were used . The intervention program consisted of 216 sessions of 40minutes each , in which oral narrative activities were combined with other activities related to the automation of morphosyntactic skills . Significant gains were also made in the group of children with SLI versus controls in total ungrammaticality , ungrammatical sentences , morphological and syntactical errors . In conclusion , a combined program of both storytelling and morphosyntactic skills improves grammatical achievement in pupils with SLI .
