In a guide shared by the Carnegie Corporation of New York and the Alliance for Excellent Education, Vanderbilt professors Steve Graham and Michael Hebert describe the evidence for how writing can improve reading. Among the recommendations:
Have Students Write About the Texts they Read: Students’ comprehension of science, social studies, and language arts texts is improved when they write about what they read
Teach Students the Writing Skills and Processes that go into Creating Texts: Students’ reading skills and comprehension are improved by learning the skills and processes that go into creating texts
Increase how much Students Write: Students’ reading comprehension is improved by having them increase how oftehn they produce their own texts.
