★ The Verdict

Teaching four clear reading strategies with real college texts boosts comprehension for students with IDD.

01Research in Context

01

What this study did

Prahl et al. (2023) worked with four college students who have intellectual or developmental disabilities. The team taught a functional literacy program that used real college texts like emails, syllabi, and assignment sheets.

They used a multiple-baseline design across reading skills. Each student learned to preview, question, summarize, and check understanding while reading.

02

What they found

All four students used the reading strategies more often and more correctly after the lessons. The gains showed up right away and stayed high.

Students said the tools helped them understand real college work, not just school worksheets.

03

How this fits with other research

Schertz et al. (2018) found similar gains in younger students with ID using a text-centered curriculum in elementary school. The new study moves the same idea up to college age.

Heslop et al. (2007) taught reciprocal teaching to adults with mild ID and also saw big reading gains. Alison’s work adds functional texts like course syllabi instead of story books.

Palka Bayard de Volo et al. (2021) warned that almost no studies target college students with IDD. This pilot helps fill that gap.

Why it matters

If you support college students with IDD, teach them to preview, question, summarize, and check real course texts. Four students is small, but the skills jumped fast and stayed. Try the same four moves in your next session: show the student a syllabus paragraph, model a quick preview, then let them practice with an email from the registrar.

03Original abstract

The rapid growth of inclusive higher education opportunities for young adults with intellectual and developmental disabilities (IDD) has contributed to improvements in students' academics, employment, social, and independent living outcomes. However, many college programs lack a focus on functional literacy, a critical skill for success in adulthood. This study evaluated whether a functional literacy intervention was associated with an increase in the percentage of reading comprehension strategies implemented accurately for college students with IDD. A multiple probe across functional literacy stimuli (e.g., academic assignments, employment emails, social text messages) was replicated across four students. Results indicated an association between the intervention and percentage of strategies implemented accurately. Suggestions for future research and implications for practice are provided.
