This study surveys a total of 127 L2 writing-related articles published in English Teaching over the past 50 years (1965-2015) with reference to research methodology, participants, and themes. The key outcomes are as follows. These articles on L2 writing in English successfully embrace diverse methodological approaches, not displaying a heavy reliance on quantitative methods. Among the study participants, those in higher educational settings maintain a comfortable lead, calling for more articles with elementary and secondary school students. A notable proliferation has been observed since the mid-1990s along with a numerical growth in articles on L2 writing. The research theme of classroom instruction appears most often over the journal’s 50-year history, followed by learner traits and characteristics of Korean students’ writing. The topics of assessment and technology use have gradually evolved into two of the major content areas in L2 writing research, while the theme of skill integration has remained under-researched. Overall, L2 writing research produced in English Teaching seems to exhibit diversity in methodology, participants, and themes.
