This study developed and evaluated the feasibility, practicality, and preliminary effectiveness of the Social Emotional Learning (SEL)-based Puzzle Expression Emotion media to improve emotional regulation among second-grade elementary school students. The study used a Research and Development design following the ADDIE model. Feasibility was assessed by subject-matter and media experts, practicality by classroom teachers, and preliminary effectiveness through a one-group pretest-posttest field trial involving 51 students from two public elementary schools in Surakarta. Data were collected through interviews, observations, validation sheets, practicality questionnaires, and an emotional regulation instrument. Quantitative data were analyzed descriptively, followed by a paired-sample t-test and N-gain analysis. The results showed that the media obtained 88.33% from the media expert and 90% from the subject-matter expert, indicating high feasibility. Teacher responses reached 83.33%, indicating high practicality. The effectiveness test showed a significant difference between pretest and posttest scores (t = -14.411, p < 0.001), with an average N-gain of 0.3761, which falls into the moderate category. These findings indicate that Puzzle Expression Emotion is feasible, practical, and preliminarily effective for improving students’ emotional regulation. Future studies should apply a stronger experimental design, longer implementation, and clearer psychometric reporting.
