Before starting the experiment, the main aims of the study were meticulously described to the students. During the seven weeks, the students had to use the vocabulary program both inside and outside the classroom, and they had to answer the SMS sent to them by the teachers. Sometimes they had to listen to some useful files sent to them via Bluetooth for increasing their understanding of the newly-learned vocabularies. On the other hand, students in the control group utilized the paper flashcards for learning the new vocabularies. On the one side they had the new word and the pronunciation, and on the other side the meaning of the word in their mother tongue and L2 as well. To assess the newly-learned vocabularies, a validated multiple choice test was administered after the study. Afterwards, to find the answer for the two research questions, the qualitative method was used to interview 10 students from the experimental group with regard to the use of m-learning in FL vocabulary learning and 10 students from the control group who used the flashcards as the main strategy for learning new vocabularies. It is important to note that the students were selected randomly and all the interviews were recorded with an MP4.
