In this paper, I designed the development theory and teaching model for integrated science
curriculum by analyzing a diversity of educational curricula and integrated science education
practices. There are the results of this paper as follows: 1. After analyzing the curriculum-developing theories presented by Tyler, Johnson, and Posner, I have drawn indispensable factors to develop the integrated science education. Based upon these factors, I have set a whole framework for the integrated science curriculum and design overall curriculum-developing model. I based knowledge-centered integrated science education upon discipline-centered curriculum, social problem-centered integrated science education upon experience-centered curriculum and individual interest-centered integrated science education upon human-centered curriculum. 2. In setting up an overall framework for the integrated science education I sorted out teaching plan from curriculum developing. As I have designed curriculum-developing models, I have designed teaching models in three different directions of integrated science education; To the knowledge-centered teaching model I applied concept-related and exploration-related development method in order to integrate the knowledge of physics, chemistry, biology, and earth science. To the social problem-centered teaching model I applied process-centered development method such as a role-play in order to solve science-related social problems. To the individual interest-centered teaching model I applied the project method which gives the students an opportunity to achieve self-realization through the process of letting them choose the learning contents and conduct investigation for themselves. This study, as a preparation of the new science curriculum, will be applicable to the development of the science curriculum models and can be referenced as the direction of the integrated science education in school.
