This article focuses on improving the ability to analyze the structure of job application letters by using puzzle media in grade XII students at SMK 5 Surabaya. This research was conducted because students often have difficulty in analyzing the text of a job application letter, even though this material is very important for daily life, especially in finding a job. The research method used is Classroom Action Research (PTK) which consists of two cycles. Each cycle includes planning, execution, observation, and reflection. In this study, puzzle media is used as a learning tool to improve students' analytical thinking skills. The results showed that the use of puzzle media significantly improved students' analytical ability from pre-cycle to second cycle, with the level of learning completeness increasing from 34.29% in pre-cycle to 87.68% in second cycle. Puzzle media is effective in improving students' analytical skills, and it is recommended to be applied to other subjects with appropriate learning strategies.
