“…It is important to note that the proficiency level descriptions in Figure 5 are diverse and may vary depending on the specific framework or context. Some instances include specific levels like advanced [50], pre-intermediate [71,74], upper-intermediate [36,58,65,68], and intermediate [26,52,54,66,69,70], while others have more general descriptions such as beginner-tointermediate [51], intermediate-to-upper-intermediate [72] However, some studies provided no information except the participants' college grades [39][40][41][55][56][57]59,60,[62][63][64]67]. This distribution indicates that corpus-based collocation instruction was investigated across a range of proficiency levels, catering to learners at different stages of language proficiency.…”
