This study aimed at designing a model of instructional materials for Academic Writing Course focusing on research paper writing. The model was designed based on the Curriculum at the English Education Study Program, Faculty of Language and Art Education of IKIP PGRI Bojonegoro, East Java, Indonesia. This model was developed in order to improve students’ skill in writing research paper which is one of the prerequisite tasks before graduating from university. The steps of this research and development consist of needs analysis, document analysis, model design, model development, and model experimentation. The researchers conducted needs analysis to the fifth semester students and three academic writing teachers, in order to generate information dealing with the students’ needs in academic writing course materials. The needs analysis and documents analysis were dug up through questionnaire, interview, and discussion among students and academic writing teachers. The documents analyzed in this study were syllabus, lesson plan, and the existing textbook. The model design used is derived from Borg and Gall (1983) and Sukmadinata (2008), in which there are four steps, i.e. (1) exploration phase; (2) model development phase; (3) model experimentation phase; and (4) dissemination and model implementation phase. The results of needs analysis questionnaire reveal that students need to be taught how to write academic writing in terms of journal article since it will be the final project of the students at the end of their study in university. Instructional materials with different strategies focused on research paper writing are needed by the students.
