difficulty of information“ Edyburn, 2002

Traditional Approach to Assistive Technology for Reading
• Focuses on decoding• Replaces reading with listening• Audiobooks• Text-to-Speech• Adult or peer reader
• Necessary but not sufficient for many learners

Cognitive Re-Scaling
• Grade level text may be inaccessible for multiple reasons• Reading level too high• Student is unable to decode • Student is has difficulty with the complexity of the text
• Vocabulary level too difficult • Student does not have the pre-requisite
background knowledge• Student needs visual/graphical support

Summarization
• Reduces text down to key points• Decreases need for student to comprehend and
then determine importance of information• Allows student to focus on vital information

Supporting Vocabulary
• Vocabulary knowledge correlates strongly with reading (and oral) comprehension. – (Hirsch, 2003)
• About 2000 words make up 90% of words in novels for teenagers (Hirsch and Nation, 1992)
• Decreasing vocabulary complexity increases readability and comprehension for students who need it
• Pre-teaching difficult vocabulary which must be retained for meaning increases understanding

Make it Visual
• About 65% of people are visual learners• Graphics, especially infographics, help
students breakdown information• Non-language based information (colors,
shapes, arrows) help organize language based information (words)
