Integrating critical thinking (CT) into English as a Foreign Language (EFL) instruction has become a pedagogical imperative in higher education, particularly in contexts striving to foster 21st-century competencies. While existing research has largely focused on intervention programs and theoretical models, there is a limited qualitative understanding of how EFL instructors embed CT within the actual teaching of language skills. This study investigates the pedagogical approaches employed by Indonesian university instructors to promote CT in reading, writing, listening, and speaking courses. Guided by the research question: What pedagogical approaches do Indonesian university EFL teachers use to promote CT in the teaching of the four language skills?, the study employed a qualitative research design. Data were collected through semi-structured interviews with eight EFL instructors (two per skill) from three private universities in Jakarta. Thematic analysis revealed four core themes: conceptualizing CT, skill-specific instructional strategies, challenges in implementation, and perceived student development. Findings indicate that while instructors share a strong commitment to CT, its integration is shaped by skill type, student proficiency, and institutional constraints. The study contributes novel qualitative insight into classroom-based CT pedagogy and offers practical implications for teacher education and curriculum design. Limitations include a small, urban-focused sample. Future research should consider broader, comparative contexts and incorporate student perspectives to deepen understanding and applicability.

English writing, particularly essay writing, is one of the most challenging skills for English as a Foreign Language (EFL) learners. Producing cohesive and coherent texts has become increasingly important. This study focuses on the role of synonymy as a lexical cohesive device in the essay writing of EFL students, specifically examining how frequently Albanian university students use synonyms in their essays. Additionally, the study explores how synonymy contributes to creating a well-structured and cohesive essay. Fifty-six first-year students (male and female) from the Faculty of Foreign Languages, English Department, were purposefully selected to write 56 descriptive essays. A qualitative research design was employed, with writing tasks serving as the primary data collection instrument. The data was analysed using qualitative content analysis procedures. The findings showed that synonyms were used more frequently than near-synonyms in the students' essays. It was also found that the students used various synonyms and near-synonyms to achieve logical cohesion in their writing, despite having limited knowledge of synonymy as a lexical cohesive device. Furthermore, the students had difficulty selecting the appropriate synonyms due to their insufficient vocabulary.
