The purpose of this study was to investigate orientation toward teaching of science teachers had shown in lesson on Law of Definite Composition for middle school students and the factors which influenced its formation. To achieve this, we collected survey materials by recording and analyzing lessons of 8 teachers, interviewing them, and using CoRe questionnaire. From teachers' activities in lessons, we found their orientation toward science teaching, and through analyzing collected materials, drew the factors which influenced the formation of orientation toward science teaching. The result identified two types of orientation toward science teaching: activity-directional and lecture-directional. The former, activity-directional was categorized further as exploration and non-exploration; the latter as interaction-centered and content delivery. The main factors which affected the formation of orientation toward science teaching were reflective thinking through teaching experiences, interaction with colleagues, consideration on education environment, training as a learner, and their own interest and curiosity. Among them, the reflective thinking through teaching experiences was strongest cause, and teacher's interest and curiosity was even limited, also influenced positively. On the other hand, unlikely other factors, consideration on education setting affected negatively to build teacher's teaching orientation. Interaction with colleagues, training for teachers by universities and graduated schools acted on a bit, but had a limit just for mainly developing science content knowledge.
