This research intended to find the desirable orientation of writing education for students majoring in science and engineering. The survey was conducted to investigate the experience and perception of writing of 268 students majoring in science and engineering. Also students who relatively had more writing experience were selected for focus group interview in order to have an in-depth understanding on survey. Finally, the two investigations were combined to find the implication of education of writing for students. The results of the research are as follows. First, the students of science and engineering who participated in the research not only had a relatively insufficient writing experience, but lacked enough education opportunity on systematic writing. The satisfaction of the writing subject was directly affected by the quality of writing instructor and, feedback of the writing and writing process. Second, the students who participated in the research went through various difficulties in their writing process, but the efforts in trying to figure out the cause of the difficulties were relatively insufficient.
