"Do subtitles affect language learning?" is a comprehensive study that explores the role of subtitles in foreign language learning. The book is based on a qualitative study that includes semi-structured interviews with 20 students who regularly watch movies with subtitles. The results show that the use of subtitles not only increases learners' motivation but also reduces their anxiety in the learning process. The author, Hilal Yildiz, argues that watching subtitled films enhances students' learning abilities and encourages them to engage more deeply with the target language. Furthermore, the importance of subtitles as a tool for promoting engagement and conveying fundamental knowledge is emphasized. The book concludes with the assertion that further research is necessary to fully harness the potential of subtitled films in language instruction.
