This report describes a program for improving students' writing skills in the areas of mechanics and organization through the implementation of a Writer's Workshop. The targeted population consists of fourth and fifth grade students in a Midwestern community located outside of a major city. Evidence for the existence of this problem is shown through teacher evaluation and student self-evaluation checklists, teacher developed rubrics, and teacher-student conferences of writing samples. Analysis of probable cause data revealed in literature indicate: the lack of teacher training in the teaching of writing, the lack of time devoted to the implementation of formal writing, and the reliance of previous teachers' ineffective strategies utilized in the teaching of writing. Motivation was also apparent as a probable cause in the literature. A review of solution strategies in the literature revealed that components of Writer's Workshop were helpful in improving students' mechanics and organization in writing. The Writer's Workshop approach encompasses a variety of mini-lessons including punctuation, capitalization, sentence structure, word choice, supporting details, transitions, and editing, to develop and improve mechanics and organization of student writing. All of these and other components of Writer's Workshop will be implemented in this study. Post intervention data indicated an increase in the correct use of mechanical and organizational writing skills by the targeted fourth and fifth grade students. Through the post self writing reflection, students also demonstrated an internalized satisfaction towards their writing. Contains 37 references, and 4 tables and 8 figures of data. Appendixes contain checklists, writing prompts, rubrics, self reflection for students, and a letter to parents. (Author/RS)
