Students in our schools do a great deal of writing - writing has always been regarded highly in our educational system. We, as teachers, are responsible for giving our students most of the writing that they do and, because of this, we need to answer some pertinent questions: e.g. Do we know why we give our students the writing? Are we aware of where writing fits in the overall learning process of our students? Is what we are actually doing in the classroom with respect to our students' writing the same as what we think we are doing? This study is concerned with questions such as these in order to determine what is current practice, and to critically discuss such practice in terms of its impact on the learning success of students. What then, are the uses made of students' writing? Why do teachers set it? How do they mark it? What uses are made of it by teachers after they have marked it and handed it back? Two research reports are considered in detail which focus on such issues in order to determine what is happening across the curriculum at about middle secondary school level.
