As an important cultivating part in "excellent engineer" program in department of automation in Beijing Institute of Petrochemical Technology (BIPT), the Scientific Writing course is a compulsory course, which belongs to ability cultivation module in discipline of control system. The fundamental goal of this course is to enable students to achieve the improvement of knowledge, ability, awareness, quality, potential and so on. In view of the shortcomings of the traditional Scientific Writing course, such as the inconsistency between content setting and ability training and difficult to mobilize students' subjective initiative, considering the mutual relations among the three courses of information retrieval, technical writing, and specialized English, a novel three-in-one course of Scientific Writing is proposed. Then within the context of the department of automation at BIPT, research and exploration on specific plans of curriculum design for the novel three-in-one course of Scientific Writing are carried on. The design process is based on the curriculum system of automation, of which the main line is to build engineering ability and quality. To achieve this goal, the engineering educational concept of CDIO and the system engineering theory of “design target exploration-teaching content confirmation-evaluation content refining-evaluation system construction” are applied. The basic idea of curriculum design is to construct integrated curriculum system based on the main line of ability cultivating and to take use of practice driving teaching mode, in order to make students not only learn knowledge including English and Chinese information retrieval and utilization, scientific writing skills, and how to read, write and translate scientific papers in both Chinese and English, but also establish the communication consciousness both in English and Chinese. After more than five years’ implementation, the new designed three-in-one course helps students in automation develop competence in international perspective of academic and scientific exchanges, improve the engineering quality of communication in both English and Chinese writing, develop their potential of further development in professional and related fields.
