“…Some studies have shown that students can successfully comprehend difficult texts. For example, two studies compared young readers partner reading with texts at different difficulty levels and found that the greatest gains occurred for students who read texts two years above their current level (Brown, Mohr, Wilcox, & Barrett, 2017;Morgan, Wilcox, & Eldredge, 2000). Although some studies find no difference in terms of comprehension outcomes when students read different levels of texts (Mathes & Fuchs, 1993;O'Connor, Swanson, & Geraghty, 2010), others have shown that students grow in fluency and comprehension when teachers use difficult texts in conjunction with strong instructional support (Stahl & Heubach, 2005).…”
