Need analysis-based lesson plan for English instruction in the faculty of science

English is one of the required subjects in Universitas Mulawarman, and its inclusion in the curriculum of each faculty is different. In natural science faculties, for example Agricultural Faculty, Medical and Health Sciences Faculty, and Science and Engineering Faculty, English is included in the even semester. As a general required subject, its learning objective is however still debatable: Is it to introduce English to the students? Is it to drill students with the English skills? Or is it to help students write an academic writing in English? The various objectives of the English learning in those faculties bring about confusion for the lecturers in designing the lesson plan. This paper is aimed at finding out the students' need of English as their required subject so that the learning process is well-guided. There are two classes of the three faculties that will be involved in this research. Each class consists of about 40 students, and the researcher will take 50% of the total number of the students from each class. They are supposed to fill in the questionnaire containing some questions about the learning materials and the class activities they need. Their answers to the questions will be used as the guideline for the English lecturers in designing the lesson plan so that it meets the students' need.
