摘要：This article aims at presenting how the difference and the diversity in the classroom are expressed through language based on the way the participants interact with social identities. In this perspective, this text presents how High School students from a public school interact with categories of religious groups. The theoretical background that based the data analysis is the Membership Categorization Analysis and the data used in the analysis are the results of audiovisual recordings of a qualitative-interpretative ethnographic research method. The analysis shows that religion is a social marker in the classroom. Some religious identities were assumed, by the other side, some identity religious were rejected. These results point out the importance of looking at diversity and difference in the classroom.
