Research on self-directed learning practices has ascertained various potential benefits of learner achievement. As mobile technology offers highly practical and portable usage for self-directed learning, studies on language learning practices through technology-based applications have become prevalent among adult learners. This study aimed to examine learners' digitalized self-directed language learning practices for enhancing their English language skills at the tertiary level. The study employed a mixed method design, and the data were collected from 182 EFL learners at a higher education institution in Türkiye. The data were analysed through descriptive statistics and content analyses. The results demonstrated that the majority of the participants use mobile phones besides computers and tablets. However, their level of frequency in using these digital devices in English signaled a low level. Furthermore, results in association with the self-directed practices of learners for improving language skills evinced distinct language learning practices supported by technology-mediated applications and platforms. It was also concluded that learners need a well-organised self-directed learning practice in digital platforms. The study addresses key attributes of practical implications adhering to digitalized self-directed language learning practices for more efficient outcomes in advancing language skills in EFL instruction.
