In details, the democratic climate of Civic Education classrooms played an important role in fostering student civic knowledge and interpretation skill, student engagement and student concepts of citizenship in North Sulawesi. However, democratic climate was found not to contribute significantly to the level of student concepts of democracy. This implies the importance of developing a Civic Education classroom that is characterised with democratic climate where students are provided with chances to practice more reflective thinking. Such a classroom is more likely to facilitate students to obtain civic knowledge and interpretation skill, to make them engaged in Civic Education classrooms and to help them to develop concepts of citizenship properly. These results in general support the importance of social and cognitive environment of classrooms as it is suggested by previous researchers, such as Allodi (2002), Aikin as reported by Morgenstern and Keeves (1997) and Fredricks et al. (2004). The finding that democratic climate does not play statistically a significant role in developing student concepts of democracy in North Sulawesi is not easy to explain because other research (e.g. cross-national studies of Civic Education in 1975 and 2001 by Torney-Purta et al.) has suggested that democratic climate played important roles in developing the student understanding of democracy.
