A few years ago, moral education was made compulsory in public elementary and high schools in Japan. That created a problem because teachers can now highly influence students’ values and beliefs through their teaching. To address this issue, I developed a practical discussion-based activity for pre-service teachers about various everyday practices and beliefs related to religion and spirituality. The study showed that through the activity, the students realized their perspectives on values, ethics, and religion. The pre-service teachers with such a raised awareness will be more able to recognize and accept other people's socio-cultural differences and teach in a more objective way.
