The importance of dictionaries in vocabulary, receptive and productive skill acquisition has long been proven. It is essential for language learners to choose suitable dictionaries, to be aware of various types of dictionary information, and to use appropriate dictionary consulting strategies. In addition, among dictionary types, monolingual and bilingual emerged as the most common categories, each having its own benefits and shortcomings. Thus, this study is undertaken to investigate English-majoring university students’ perception of their use of dictionaries, particularly regarding the two mentioned types. The research team designed a questionnaire of 60 second-year and 60 fourth-year students, then selected 5 students from each group for an interview. Quantitative and qualitative results from the survey and interview were collected, analyzed, and compared to offer insights into students’ dictionary consulting strategies and their opinions on monolingual and bilingual dictionaries. Data suggested that bilingual dictionaries were the more favored type for both groups of students. Fourth-year students were able to exploit dictionary elements more properly, while second-year students employed dictionary consulting strategies more effectively. Regarding their perceptions of the advantages and disadvantages of each type, monolingual dictionaries assist learners better in internalizing the language with its abundance of information and the English environment they create. Meanwhile, bilingual dictionaries come in handy in cases that require speedy digestion of information, thus more convenient when it comes to receptive skills.
