SUMMARY
A survey of Center for the Study of Islam and Society (PPIM) in 2017 states that Islamic Education course is one of the triggers for the rise of intolerant attitudes and thoughts in the younger generation of Indonesian Muslims. This background encourages this paper to examine the content of tolerance in Islamic Education textbook of the 2013 curriculum. This study is a library research using Fairclough’s Critical Discourse method for senior high school’s Islamic Education textbooks of X, XI, and XII grade. The results of the study show that, (1) the general framework of the 2013 curriculum is oriented towards building an inclusive generation of young Muslims, but the textbooks are ambiguous, (2) the discourse battle between substantive Islam and Islamism in the curriculum causes ambiguity in the textbooks, and (3) the book’s producers are not official institution of Islam, therefore the course’s teaching material is personal, as the author’s personal opinion. Implementation and limitation of papers are presented at the end of this paper.
