These modules scaffold the English-medium instruction, enabling the undergraduates to improve their English language skills, which are necessary in following their selected degree programs. The reasons for considering it necessary to maintain an advanced competency level in English in university education are mainly the disparities in the education system in the country, which cause the students’ demotivation and a lack of interest in studying English. Consequently, the perceived effectiveness of the ESL course modules offered to the undergraduates has also been much debated on their capability of presenting the language according to their specific English language needs. The study, therefore, explores the issue, utilizing a qualitative re-evaluation methodology, in which 30volunteer participants have provided in-depth analyses of their learning experiences. Prior to the main study, a comprehensive Needs Analysis was conducted to identify the specific language requirements of the participants, and the data collection included their writings on specific language needs, interviews as well as structured questionnaire surveys conducted for 15 weeks. The collected data were analysed using qualitative content analysis, and it was understood that the offered course module is generallyeffective in addressing their basic language needs only. However, the study emphasised the need for more and more engaging and integrated language support, under which the students are grouped according to their language proficiency levels.enESLlanguage needsEMIundergraduatesperceived effectivenessArticlehttps://doi.org/10.54389/OJWC4228
