Description
Purpose: Over-identification of Navajo Head Start children into special education on the Navajo Reservation has come to the attention of Tribal leaders, Educational leaders, and parents due to the use of invalid assessment measures. Dynamic assessment (DA) of narratives may be a tool for distinguishing language differences from language disorders. The purpose of this study is to determine whether the Predictive Early Assessment of Reading and Language (PEARL), a dynamic assessment of narratives, accurately classifies Navajo Head Start students with typically developing (TD) language or with language impairment (LI), and to examine which measures best predict children’s overall performances on the PEARL.
Method: Ninety, 4- and 5-year-old Navajo preschoolers with LI and with TD language were selected. Children completed the PEARL, which measured both language comprehension and production using pretest and posttest scores, and a modifiability scale. In addition, children completed the Clinical Evaluation of Language Fundamental, Preschool, Second Edition (CELF – Preschool 2) and language samples. A Navajo Speech Language Pathologist confirmed the diagnosis of the participants. Research assistants pretested, briefly taught the principles of narrative structure (story grammar, language complexity and episode) and evaluated response to learning using an index of modifiability.
Results: Results of discriminant analysis indicated that PEARL pretest differentiated both ability groups with 89% accuracy. In addition, posttest scores discriminated with 89% accuracy and modifiability scores with 100% accuracy. Further, the subtest story grammar was the best predictor at pretest and posttest, although modifiability scores were better predictors of both ability groups.
Conclusion: Findings indicate that the PEARL is a promising assessment for accurately differentiating Navajo preschool children with LI from Navajo preschool children with TD language. The PEARL’s recommended pretest cut score over-identified Navajo children with TD language; therefore, a new recommended cut score was determined.

Description
The purpose of the Preschool Intervention for Embodied Storytelling (PIES) study was to evaluate the efficacy of a drama-based story time intervention on at-risk preschool students’ emotion knowledge, story retell and story comprehension skills. Six classrooms with 44 students were randomly assigned into drama-based intervention and dialogic reading control groups. After four weeks of intervention sessions twice per week, students’ emotion knowledge and story retell skills were assessed with distal measures. During the program, students’ comprehension of the stories was evaluated weekly. Participants did not show significant main effects on any measures, however investigation of simple effects revealed differences in gains over time for intervention students in their story retell skills. Despite lack of significance, effect sizes for story retell were promising. Mean differences in story comprehension skills were consistently in favor of the intervention group for the duration of the program. Teacher participants showed an increase in their positive perceptions of drama-based instruction, but their own use of these strategies at story time was variable before and after observing the PIES program. Drama based instruction through PIES may be a favorable intervention strategy for preschool students as they develop narrative skills that are a prerequisite for future reading comprehension success.
