Struggling adult readers and college students used an intelligent tutoring system to learn reading comprehension strategies. The study found that:
1) Struggling readers spent significantly more time (13.2 minutes vs 8.8 minutes) completing the tutorial, but achieved comparable comprehension scores to college students.
2) Both groups selected easy and hard questions in the tutorial at similar rates, contrary to expectations that struggling readers would choose easier questions.
3) While struggling readers took longer to answer questions, their performance on first attempts was comparable to college students, suggesting the tutorial helped both groups improve reading comprehension.
