Dictionaries are among the most commonly employed materials in the foreign language learning process. Different types of them like monolingual, bilingual, collocation, and thesaurus dictionaries in both printed and electronic forms are at the disposal of learners to help them with lexical problems. As each type holds different characteristics, the dictionary use patterns are shaped in accordance with the specific needs and expectations of learners. This study aims to find out some details on prospective English language teachers' dictionary preferences during their struggle to develop foreign language skills. The study was conducted with the participation of 55 freshman students taking the "Word Skills Course" in the English Language Teaching (ELT) Program at Ondokuz Mayıs University. The data were collected through a written questionnaire which consists of five multiple choice and six short openended questions. The findings yielded by the numerical and qualitative analyses indicate that all of the participants somehow utilize dictionaries (an average possession of 2 printed dictionaries per student) and think that dictionary use is an indispensable part of language learning. However, they are not entirely sure of whether they employ dictionaries effectively or not. Almost half of the participants (42%) think that they cannot use dictionaries effectively. As for the dictionary types, the majority of the participants (58%) prefer printed monolingual dictionaries. In the light of the findings we suggest that ELT students' awareness and knowledge as to the available different types of dictionaries should be raised through informative elaborations on their distinguishing functions; and their skills for the effective use of dictionaries should be consolidated through regular instructor-guided practices on dictionary use within and outside the classroom.
