“…It was said that EFL learners could use a variety of collocations, but it does not necessarily mean that they can perform the true mastery and fluency of the target language [15], [16], [17], [18]. Moreover, mother tongue impact, linguistic properties of collocations, educational context, learners' cognitive and metacognitive abilities, learners' language proficiency, teachers' and learners' perception of collocations, and the use of corpus-based materials might make contributions to learners' collocational acquisition [3], [4], [12], [13], [19], [20], [21], [22], [23], [24], [25], [26], [27], [28], [29], [30], [31], [32], [33], [34], [35], [36], [37], [38], [39]. Understanding all of this, the explorations of learners' and teachers' insights into using collocations to enhance academic writing, including the role, arising problems, and practical solutions, might yield valuable results under the current research setting.…”
