The document discusses developing learning materials for scientific writing courses without duplicating existing resources. It analyzes the needs of both academic and pre-service writing courses. When creating materials, the developer should consider the role of subject teachers, students' writing skills and attitudes, and assumptions about how students learn writing genres. The document outlines three types of materials: those that discover genre features, provide content to write about, and increase awareness of genre conventions through practice. The goal is to create credible, non-textbook materials tailored to specific course needs.
