It is a challenging aspect that requires significant effort from students and requires specific strategies that teachers can provide to achieve a decent level of learning. Significantly, this research aimed to investigate students' attitudes towards formal and informal ways of vocabulary learning. This study drew upon a mix of quantitative and qualitative methods. Both questionnaires and semi-structured interviews were employed to collect data. Statistical tests and thematic analysis were employed to analyse the data. In this study, the participants were students in the Department of English at Larbi Ben M'hidi University; Oum El Bouaghi. For the questionnaire, thirty male and female students took part. Additionally, and ten male and female students participated in a set of semi structured interviews. The findings of this study display that informal methods can improve EFL students' vocabulary knowledge and reveal the EFL learners' positive attitudes towards the use of social networks as a supplementary tool to enhance their vocabulary knowledge. In general, the findings indicated that students have positive attitudes towards the use of formal and informal ways of learning as well as the notion of integrating social networks into the educational system, which is deemed extremely beneficial and effective for improving vocabulary. Accordingly, incorporating informal methods, especially ones that integrate social media platforms, into EFL classrooms is recommended in order to enhance the students' vocabulary competence. It is also suggested that teachers and students be aware of, and serious about, the importance of using both formal and informal strategies for vocabulary enhancement.enVocabulary learningEFL classroomInformal MethodsOther
