Hidden curriculum in TFL and EFL coursebooks

Coursebook is an inseparable part of ELT and TFL (Turkish as a Foreign Language) in Turkey. It provides teachers self- esteem and a qualified teaching process with support of interesting authentic cultural examples. Learners get the opportunity to learn about different cultures and use target language at the same time. This looks like an ideal procedure for most of Turkish ELT and TFL teachers; yet, the other side of coin is different. While learners are spending enjoyable time, they are unconsciously exposed to Turkish and American culture, as a student cannot learn a language without becoming a part of that culture. So, coursebooks are not innocent materials and carefully analyzed in the study for that reason. In accordance with that idea, this study aims to show the hidden threat of Turkish and American culture under the headings "Us and Them Understanding: Identity Perception", "Writer's positive and/or Negative Attitudes towards a Particular Subject" and "Sense of Belonging: Privilege of Being a Part of that Culture" by taking TFL coursebookHitit 3 and EFL coursebookLanguage Leader as the sources. Results show that writers shape the ideological understanding of students by their representations of both native and target culture by creating a collectivist and individualist understanding. Results of that study show important facts to Turkish ELT and TFL teachers and students in order them to preserve their national culture. Study also aims to fill a gap in literature by proving the idea such as "Although teaching language is necessary for establishing a future, it should not make us forget our own identity."
