A teacher experimented with her fourth grade students in order to determine how much revision took place in their writing. Originally, the teacher had been dissatisfied with the way she taught writing. Children wrote stories; she graded them. Then she began seriously examining the revision process as she observed it in her classroom. Students were given an assignment and told to revise it. Various approaches to teaching revision skills were utilized. The teacher made entries in a log to record students' development. Although at first it did not appear that students were implementing the skills, upon closer inspection it became apparent that there was much more revision occurring than the teacher had originally believed. As the months passed, the class continued to work on writing and became more conscious of revision in their writing. Finally, a set of guidelines emerged, including asking students about their choices, allowing students access to each other as they write, and letting students know they will have the opportunity to revise. (Samples of the writing and revising of one of the students are included.) (DF)
