The Capstone Design class, operated in the Project Based Learning format, is a class in which three groups of learners produce assignments such as beginner-level Vietnamese conversation textbook manuscripts, lecture notes, and lecture videos by following the process of ‘assignment (first draft) - peer evaluation - reflection of peer evaluation opinions - revised manuscript - reflection journal.’ In this study, we analyzed the presentations of the first and second groups’ drafts, peer evaluations by fellow groups, revised manuscripts that accepted peer opinions, and reflection journals written by all students during the second and third weeks of the 15-week class. In particular, when comparing the draft and the revised task reflecting peer evaluation, it can be seen that learners themselves recognize the importance of communication and collaboration capabilities that accept peer evaluation opinions along with enhancing the completeness of the task. In addition, through the analysis data of two consecutive weeks, it was recognized that not only the ability to accept peer-reviewed opinions but also to present peer-reviewed opinions is communication and collaboration capabilities, and a respectful and honest attitude is necessary for this.

The purpose of this study is to investigate the influence of social factors on the use of honorific language by discourse completion test. Participants complete a short discourse by filling in their responses in conversations that may occur in families, schools, and workplaces where the social status and solidarity of the listener is predetermined. Honorific styles of sentence endings of their responses are analyzed by the generalized linear mixed model. The results show that social status and solidarity are statistically significant factors in the use of honorific styles, but their effects are dependent on the discourse situation. The ratio of using honorific styles gradually increases as the formality of situation increases (i.e., family < school < workplace). Interestingly, when the solidarity is low at the workplace, the ratio of using honorific styles is consistently high regardless of the social status of the listener. These results show that the use of Korean honorific styles is pragmatically changing according to the discourse situation.
