Democratic classroom practices are all strategies adopted by classroom teachers to actively engage students in the learning processes. Considerable literature assessing influence of Civic Education on youths' active participation in a democratic society exists. Not much have reported an empirically conducted study on classroom best practices adopted by Civic Education teachers in the Global South. This paper examines classroom democratization by Civic Education teachers in South East Nigeria, students' and teachers' perceptions of democratic classroom, and challenges confronting classroom democratization. Focus Group Discussion and Democratic classroom questionnaire were used to elicit information from 151 civic education teachers and 1400 senior secondary school one (SS1) students. Findings revealed that Civic Education teachers in South East Nigeria adopted democratic classroom practices marginally. Recommendation includes more adoption of democratic classroom best practices for development of students' critical thinking abilities, preparing them to become participatory in their civic duties and reducing crimes among today's youths.
