Because writing teachers invest so much time responding to student writing and because these responses reveal the assumptions teachers hold about writing, L1 writing researchers have investigated how composition teachers respond to their students' texts. These investigations have revealed that teachers respond to most writing as if it were a final draft, thus reinforcing an extremely constricted notion of composing. Their comments often reflect the application of a single ideal standard rather than criteria that take into account how composing constraints can affect writing performance. Furthermore, teachers' marks and comments usually take the form of abstract and vague prescriptions and directives that students find difficult to interpret.
A study was undertaken to examine ESL teachers' responses to student writing. The findings suggest that ESL composition teachers make similar types of comments and are even more concerned with language‐specific errors and problems. The marks and comments are often confusing, arbitrary, and inaccessible. In addition, ESL teachers, like their native‐language counterparts, rarely seem to expect students to revise the text beyond the surface level.
Such responses to texts give students a very limited and limiting notion of writing, for they fail to provide students with the understanding that writing involves producing a text that evolves over time. Teachers therefore need to develop more appropriate responses for commenting on student writing. They need to facilitate revision by responding to writing as work in progress rather than judging it as a finished product.
