  Writing a good essay typically involves students revising an initial paper
draft after receiving feedback. We present eRevise, a web-based writing and
revising environment that uses natural language processing features generated
for rubric-based essay scoring to trigger formative feedback messages regarding
students' use of evidence in response-to-text writing. By helping students
understand the criteria for using text evidence during writing, eRevise
empowers students to better revise their paper drafts. In a pilot deployment of
eRevise in 7 classrooms spanning grades 5 and 6, the quality of text evidence
usage in writing improved after students received formative feedback then
engaged in paper revision.
