Constructed on the premise that the teacher with a written assignment to evaluate seeks procedures and activities for remediating the errors present in that assignment, this handbook is designed as a tool for the teaching of remedial composition in grades five through twelve. The handbook is composed of a checklist and a diagnostic grid, followed by discussions and activities for each of the topics listed in the checklist--perception of the task, organization, sentence structure, usage, vocabulary, and mechanics. The grid following the checklist may be used (1) to provide an initial evaluation of the strengths and weaknesses of the entire class, indicating areas in which group instruction would be beneficial; and (2) to keep track of the individual student's progress by recording individual assignments. Sample questions from the Regents Competency Test on Writing, a glossary of terms, a student writing chart, and a bibliography of additional resources are appended. (HOD)
