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.
