The objective of this developmental study is to develop a model of academic writing materials for the English Education Department learners based on the accelerated learning approach. The data of this study consisted of quantitative and qualitative data. The data sources were learners, English instructors, and experts in the academic writing materials design. Data were collected using observations, interviews, questionnaires, documents, and focus group discussion. The materials were developed in four steps: (1) analyzing the existing materials, (2) carrying out needs analysis, (3) developing materials and (4) validating them. Data were analysed using percentages for quantitative data. Miles, Huberman and Saldana technique (2014) was used for qualitative data, namely, data condensation, data display, and verification. In order to establish the trustworthiness of the data, this study implemented the triangulation method: source, method, and theory. The result of this study was a theoretical model of academic writing materials based on accelerated learning containing: (1) the components of English writing materials, (2) communicative principle, (3) learning by integrating mind, emotion, and body, (4) activating conscious and unconscious thought, and (5) relaxation, music, and suggestion.
