A systematic search across three databases (ERIC, Web of Science, and Scopus) initially identified 2807 articles, with 22 C-DA studies meeting the inclusion criteria after screening. Findings reveal that C-DA significantly enhances language learning outcomes, particularly in reading and listening and writing skills, with large effect sizes reported across multiple studies. Interventionist approaches and quasi-experimental designs were most commonly used, reinforcing the strong impact of mediation on bridging learners' actual and potential performance. While C-DA demonstrated substantial improvements in skill-based outcomes, its effects on affective factors like anxiety and intrinsic motivation were more modest. These findings highlight C-DA’s potential as a transformative tool in language assessment and instruction, particularly when mediation is tailored to learners' needs. However, integrating C-DA with complementary strategies may be necessary to address psychological and motivational factors.  https://elt.tabrizu.ac.ir/article_19621_923f830817f9888019d8b84c2e9ec75e.pdf
