Map the Gap: Analyzing ASL and Spoken English Language Growth Rates for DHH Children
INTRODUCTION
Language needs appear in American Sign Language (ASL) and spoken English for many deaf and hard of hearing (DHH) children to varying degrees and with different trajectories. We analyze the degree to which DHH children are making progress towards achieving age-expected language milestones for ASL and/or English and the influence of attaining Early Hearing Detection and Intervention (EHDI) benchmarks.
METHODS
DHH children from the Kansas Language Assessment Program–DHH who use ASL (n=51; mean age=48 months) and/or spoken English (n=69; mean age=45 months) participated. Participants vary in hearing levels, hearing technology use, and educational settings. Growth rates were calculated by dividing the change in mastered language age level in months on the ASL/English Language Milestones by the months between administrations (ASL mean=11.7 months; English mean=14.7 months).
RESULTS
For ASL, 16% of participants exhibited a growth rate above 1 (narrowing the gap), 47% increased their mastered language level but did not narrow the gap, 33% did not increase their mastered language age, and 4% showed a decrease in language level between administrations.
For spoken English, 7% of participants exhibited a growth rate above 1, 61% increased their mastered language level but did not narrow the gap, and 32% did not increase their mastered language age between administrations.
To evaluate the influence of EHDI benchmarks attainment, we conduct analyses analogous to those above for children who: met 1-2-3 benchmarks, met 1-3-6 benchmarks, and did not meet 1-3-6 benchmarks.
DISCUSSION
For ASL and spoken English, the majority of DHH children increased their language skills but did not “narrow the gap” relative to peers with typical hearing. Additional analyses aim to evaluate possible reasons for variation in language growth rates, including attainment of EHDI benchmarks, to identify ways to improve progress.
- Explain how to use the ASL/English Language Milestones measure to measure language growth.
- Describe different patterns of language development that can be captured from multiple administrations of the ASL/English Language Milestones measure.
- Apply research findings regarding ASL and spoken English growth to serving deaf and hard of hearing children.
