Adjunct aids in instructional prose: a multimedia study with deaf college students

Area of Science:

• Educational Technology
• Deaf Education
• Cognitive Psychology

Background:

• Computer-based learning offers unique opportunities for diverse student populations.
• Assessing instructional strategies for deaf college students with varying reading abilities is crucial for equitable education.
• Traditional text-based materials can pose challenges for students with lower reading proficiency.

Purpose of the Study:

• To investigate the effectiveness of different instructional conditions on factual learning in deaf college students.
• To determine if adjunct aids can enhance learning for students with low reading abilities.
• To compare the impact of text-only, multimedia, and question-based learning on factual recall.

Main Methods:

• 144 deaf college students were divided into low, middle, and high reading ability groups.
• Five instructional conditions were tested: text only, text with content movies, text with sign movies, text with adjunct questions, and a full condition combining all elements.
• Immediate, factual learning performance was measured across all groups and conditions.

Main Results:

• Students with low reading abilities in the adjunct question and full conditions showed factual learning comparable to high-ability students in the text-only condition.
• Adjunct aids and mathemagenic activities demonstrated a compensatory effect for lower reading ability students.
• The study identified specific instructional components that significantly benefit students with reading challenges.

Conclusions:

• Adjunct aids and mathemagenic activities are effective compensatory tools for improving factual learning from instructional prose.
• Computer-based science lessons can be optimized for deaf college students by incorporating supportive learning aids.
• Educational interventions should consider individual reading abilities to ensure effective knowledge acquisition.
