This study attempted to expand the range of understanding between generations and derive implications by comparing the thinking and behavioral styles of MZ generation teachers who recently joined the company through data analysis in the second year of the Korean Teacher Longitudinal Study(2022). However, in the area of student evaluation, MZ generation teachers and older generation teachers showed statistically significant differences in a large number of questions related to teachers' values (educational, student, and teaching), class activities (curriculum reorganization, teaching method, student evaluation), and job satisfaction (job satisfaction, burnout), and the differences with a certain pattern were as follows. First, in relation to student relations among teachers' values, MZ generation teachers were more positively aware of the possibility of acquired educational change than the older generation, and it was expected that teachers would play a central role in future school education. Second, there was no significant difference between the MZ generation and the older generation in terms of curriculum restructuring and teaching methods. However, in the area of student evaluation, it was found that MZ generation teachers gave relatively more active evaluation feedback to students than the older generation. Third, MZ generation teachers had relatively low job satisfaction compared to the older generation and were experiencing a high level of burnout. In the analysis of satisfaction factors, the response average was lower than that of the older generation in terms of class activities, student guidance and class management, students' growth, social development, and remuneration levels, and only 'time margin' showed a relatively high response average. Based on these findings, a series of follow-up studies targeting the new generation of teachers were needed, and policy responses to the improvement of satisfaction and burnout mitigation of MZ generation teachers were proposed.
