L2 （second language） writing teaching and research is greatly influenced by the advent of computer technology. This paper reviews papers, in the field of DDL （data-driven learning） in L2 writing, published in international journals and in Chinese journals, and differences are found in research methodology, research perspective, and research realm. Based on the analysis of the differences, the study aims at finding out the effects of the application of DDL in L2 teaching classroom. The present study, employing semi-structured writing and learning journals, explores how English learners perceive the use of corpora in their writing process.
