The main purpose of the study is to evaluate both curricular patterns and actual outcome of nine-year integrated curriculum pilot program at elementary school level. Among major findings, which are secured from this study, are stated as follows: 1. Among major areas of learning, “comprehensive activities” and “fine arts and humanities” are two favorably chosen areas in pilot program. 2. About 80% of schools surveyed have developed school-based curriculum, and more than three fourth have adopted cross-area curricular integration and cross-subject curricular integration. 3. In the dimension of favorable effects, all of four major factors and their related items are evaluated rather high. These factors are Factor I ”Favorable Effects of Professional Growth in Curriculum and Instruction”, Factor II “Favorable Effects of Positive Feedbacks on Program Outcome”, Factor III “Favorable Effects on Identification of Curricular Reform Ideas”, and Factor IV “Other Favorable Effects”. 4.In the dimension of related difficulties, two major factors and their related items are evaluated as definite difficult problems. These two factors are FactorVI “Difficulties of Specific Fund Management and Competence-Indicators Based Measurement”, and Factor V “Difficulties of Workload Burden and Lack of Incentives”.
