Abstract

This study aims to analyze the psychometric quality of a scientific attitude questionnaire instrument for secondary school students using the Rasch Model. The instrument, developed based on Harlen’s theory, includes four key dimensions: curiosity, respect for data, critical thinking, and open-mindedness/cooperation. A survey method was employed with 30 seventh-grade students in Bandung City as respondents. Data were collected through a four-point Likert scale questionnaire and analyzed using Winsteps 4.6.0 software. The Results revealed that 16 out of 23 items fit the model based on Outfit Mean Square, Z-Standard, and Point-Measure Correlation indicators. The instrument also demonstrated high overall validity and reliability, with an Outfit MNSQ of 1.00, ZSTD of -0.17, an item separation index of 2.91, and a reliability coefficient of 0.89, indicating good discrimination and stable measurement structure. In conclusion, the scientific attitude instrument exhibits strong psychometric properties and can serve as a valid tool for assessing student attitudes in science education. However, revisions are needed for seven misfitting items to enhance clarity and construct alignment. Further validation on broader populations is recommended to ensure generalizability.

Abstract

This study investigates high school students' responses to the implementation of the 3C3R Problem-Based Learning (PBL) model in climate change education. Given the complexity of climate issues, the 3C3R model, emphasizing Content, Context, Connection, Research, Reasoning, and Reflection, was applied to foster students' critical thinking and collaborative problem-solving. A descriptive quantitative method was used, with data collected through questionnaires and analyzed using the Rasch model. The Wright Map was employed to visualize the distribution of student agreement. Findings show that students responded positively to structured materials, meaningful group tasks, and opportunities to present their work. The most endorsed items highlighted teacher preparation, honest self-assessment, and active involvement in poster presentations. However, student responses also indicated limited participation in collaborative aspects like experiment design and shared responsibility during group work. These results suggest that while the 3C3R PBL model enhances cognitive and emotional engagement, additional support is needed to improve students' communication and teamwork. The study offers valuable insights for educators aiming to deepen student involvement in climate change learning
