This study sets out to examine the relationship between teaching methods and students’ moral behaviour in secondary schools. The improvement of students’ moral behaviour in Cameroon is an ongoing process. The study deals with students’ moral behaviour which has dropped in the past five years and is increasingly gaining grounds in Cameroon. There has been a constant increase of violence, juvenile crimes, aggressiveness, cheating in exams, disrespect, irresponsibility just to name but a few deviant students’ behaviour. The objective of the study was to investigate the effects of teaching methods on students’ moral behaviour. The research applied a mixed methodological approach which is a combination of qualitative and quantitative approaches at different stages in the research process. Teaching learning methods was measured using Element Based Curriculum Development Model Questionnaire scale adopted from Aslan and Gunay (2016). The students’ moral behaviour was assessed using Understanding the Moral Values of Young People and their character development questionnaire sub scale by Beng (2018). The semi structure interview guide was adopted from Askell-Williams (2001) focusing on achievement goals (Pintrich, 2000). The validity and reliability of these research instruments were assessed and determined. The review of related literature was focused on teaching methods and student’s moral behavior with models and theories. The samples were 100 students, 50 with disciplinary problems and 50 without disciplinary problems, 7 discipline masters and 7 citizenship teachers selected for the research through the simple random sampling techniques. Data collected from the respondents was analyzed using descriptive statistics, stepwise multiple regression analysis and Pearson Product Moment Correlation Coefficient. The research findings indicated a significantly positive relationship between teaching methods and students moral behaviour. If teaching methods is improved by 10%, students moral behaviour will be improved by 0.19% .Students’ moral behaviour should be developed through teaching learning methods and the integration of moral education in all lessons in the school curriculum.
