Sentence Shaping: Written Language Intervention for Deaf and Hard of Hearing Middle Schoolers

Not applicable Interventional Vanderbilt University · NCT06860022

This study will try using shape coding visual supports to help 5th–8th grade children who are deaf or hard of hearing and use spoken English and ASL write sentences more accurately.

What this trial studies

The investigators will adapt shape coding—a system of visual symbols for grammatical roles—to support written sentence construction for children who are deaf and hard of hearing. Participants are students in grades five through eight with bilateral hearing loss who use both spoken English and American Sign Language and who already write sentences but make word order or grammar errors. Children with dyslexia, uncorrected vision loss, or severe motor impairment are excluded. The team will deliver the shape coding intervention and measure how efficiently participants learn to produce correct written sentences.

Who should consider this trial

Good fit: Ideal candidates are 5th–8th graders with bilateral hearing loss who use spoken English and ASL, can read the targeted grammatical structures, and already write sentences but show errors in word order or grammar.

Not a fit: Children with a diagnosis of dyslexia, uncorrected vision impairment, or severe motor impairments that prevent completing tasks are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, this approach could help deaf and hard of hearing students produce grammatically correct written sentences more quickly, supporting improved literacy and academic outcomes.

How similar studies have performed: Shape coding has been effective for teaching sentence structure in spoken English and has recently been applied successfully to sentence structure in ASL, but its use for written sentence construction in this population is a newer step.
