Supporting Teachers in Argument Writing Instruction at Scale: A Replication Study of the College, Career, and Community Writers Program (C3WP)
This large-scale randomized experiment found that the National Writing Project’s (NWP’s) College, Career, and Community Writers Program (C3WP) improved secondary students’ ability to write arguments drawing from nonfiction texts.
What impacts did C3WP have on student achievement?
The study team collected and scored student writing from an on-demand argument writing task similar to those in some state assessments. At the end of the year, students in C3WP districts outscored students in comparison districts by about 0.24 on a 1- to 6-point scale on each of the four measured attributes (see graph). On average, these effects are equivalent to moving a student from the 50th percentile of achievement to the 58th percentile of achievement.
