INCLUSION MODEL FOR VOCABULARY INSTRUCTION Abstract This investigation focuses on the effectiveness of vocabulary instruction for speech and language students provided by the speech-language pathologist within a classroom based service delivery model versus traditional pull-out speech therapy services. Four kindergarten students identified with a mild-moderate vocabulary delay were followed within this study as they received seventy-five minutes of direct vocabulary instruction from the speech-language pathologist each week across each setting. Standardized comparison scores obtained pretest and posttest from the Expressive and Receptive OneWord Picture Vocabulary Tests demonstrated significant gains among students within the regular education classroom for push-in services versus pull out traditional services. These findings help to support the success of the inclusion model for speech and language services in regards to vocabulary development.
