<![CDATA[Bullying remains a persistent problem in schools and can negatively affect students’ social and emotional development, making innovative preventive strategies increasingly important. This study aims to examine the effectiveness of interactive anti-bullying puzzle media in increasing bullying awareness among eighth-grade students at SMP Labschool UPI Bandung. This study employed a quantitative experimental approach using a pretest-posttest control group design. The participants were 40 eighth-grade students, consisting of 20 students in the experimental group and 20 students in the control group, selected through purposive sampling. Data were collected using a 23-item questionnaire measuring students’ understanding and attitudes toward bullying. The instrument demonstrated acceptable validity and reliability, with all items meeting the validity criteria and a Cronbach’s alpha coefficient of 0.814. Data were analyzed using normalized gain scores to compare changes between the experimental and control groups. The results showed an increase in the experimental group’s mean score from 46.30 before the intervention to 74.35 after the intervention, with a normalized gain score of 0.62, categorized as moderate. In comparison, the control group increased from 43.55 to 49.60, with a normalized gain score of 0.12, categorized as low. These findings indicate that interactive anti-bullying puzzle media can support the development of students’ awareness of bullying and promote active learning through cooperation, reflection, and discussion. The study concludes that puzzle-based media can serve as an innovative strategy for strengthening bullying prevention programs in junior high schools.]]>
