A writing folder is a resource tool which has been designed to reflect the phases of the writing process and which complements other classroom strategies and teaching methods used to enhance the understanding of this process. A field test was conducted during the 1985-86 school year to gather information on the use of writing folders in 78 North York (Ontario) schools. One component of the field study was a 23-item questionnaire distributed to and completed by teachers in the 78 schools. A selected number of classes were visited to observe students using the folders, and a checklist form was used to record observations. The results of both survey responses and classroom observations showed that writing folders seem to be well received by the teachers and students who use them and are perceived to have had a positive effect on students' writing in terms of process as well as product. The questionnaire and the classroom observation checklist are appended. (JAZ)
