<![CDATA[Climate change has become one of the most critical environmental issues affecting human life and environmental sustainability. Students’ climate change attitudes play an important role in developing environmental awareness and responsible behavior from an early age. However, studies investigating students’ climate change attitudes using the Rasch model are still limited, particularly among junior high school students in Indonesia. Therefore, this study aimed to analyze junior high school students’ climate change attitudes using Rasch analysis and to identify gender-based differences in students’ responses. This study employed a descriptive quantitative design involving 25 ninth-grade students consisting of 11 male and 14 female students from a junior high school in Blora Regency, Central Java, Indonesia. The instrument used was the Climate Change Attitude Survey (CCAS) consisting of 33 Likert-scale items. The data were examined using the Rasch model utilizing Winsteps 4.4.5 software. The findings revealed that students’ climate change attitudes were still at a moderate level. In the beliefs indicator, only 20% of students were categorized as good, while in the intentions indicator, 36% were categorized as good. The Rasch analysis showed that person reliability was 0.90 and item reliability was 0.88, representing that the instrument had good consistency and reliability. Differential Item Functioning (DIF) analysis showed that most items did not exhibit gender bias, except item C19. Overall, the CCAS instrument was considered suitable for measuring junior high school students’ climate change attitudes.]]>
