A survey measuring self-concept and writing anxiety was conducted with Chinese Korean Language Learners; data from 145 participants were analyzed using SPSS. The results showed that self-concept did significantly impact writing anxiety. However, among the self-concept subfactors, the “ideal self” did have an effect on writing anxiety. Writing anxiety was also found to have a negative effect on writing grades, but the “ideal self” did not. A mediating effect of writing anxiety was observed between the “ideal self” and writing grades. Based on these findings, a content-language integrated writing workshop teaching-learning model is proposed to help reduce learners’ writing anxiety and foster their “ideal self.”
