Hyperglossing -textual and/or pictorial representations of lexical items is found to be aiding the development of decoding, and narrow reading is a useful strategy for L2 reading pedagogy. Although the research on glossing provides mixed findings regarding the benefits, it is also acknowledged that glossing improves especially incidental vocabulary acquisition. The current study aims to investigate the perceptions of beginner students of English towards learning English vocabulary by narrow reading on "Readlang", a Web 2.0 tool that allows language learners to translate words and phrases into learners' mother tongue. The participants included 55 Turkish learners of English enrolled in the department of Public Administration at Mehmet Akif Ersoy University. The participants were asked to choose five words and/or phrases from a different text on public administration each week during the study, which lasted 12 weeks. The interviews held with the participants at the end of the study indicated that the participants perceived that their reading comprehension improved dramatically since using "Readlang". The results also indicated that the spaced repetition through flashcards helped them recycle the previously learnt lexical items.
