The purpose of this paper is to analyze the aspects and content spread of the self-reflection report by pre-service Korean language teachers after their teaching rehearsal. This is to overcome the confusion and difficulties when they write self-reflection reports. First, the general patterns of the formal construction of self-reflection report appears in the order of ‘cover(abstract cover)-table of contents-introduction-main body-conclusion- reference’, and average quantity is about 6.5 in A4 standard. And, in the content spread aspect, 8 contents are developed individually in the introduction part. It shows that the self-reflection reports develop contents that show affective characteristics or academic characteristics according to the purpose of the reports. In addition, the contents of main body are analyzing the teaching rehearsal, as well as the pros and cons, problems and improvements. At this point, the study found those characteristics when they write self-reflection reports, which are spreading the contents according to certain standards, writing reports depending on feedbacks by the instructor and imitating or modifying the former researches of the instructor. Finally, in the conclusion part, as in the introductory part, the contents related to ‘feelings and plans’ are described in the articles of affective characteristics, and the contents related to ‘summary and expectation effects’ are written in the articles of academic characteristics.
