Abstract
The aim of this research was to investigate the scientific literacy ability of the eleventh year students in the topic of heat and temperature by using Rasch model analysis. This was a case study research by applying post-test only group research design. The samples of the research were of 31 students consisting of 11 male students and 20 female students. Multiple choice test consisting of 25 items were used in this research. The test items were adapted from the PISA framework constructed (r= 0.82). The result of analysis by using Rasch model in form of Wright map display where the students 10P had high ability rate and students 04L, 07P, and 16L with the response pattern considered unfit. The MNSQ outfit value accepted was out of the limit. Generally, percentage of students- scientific literacy ability in the three competencies were categorized low.
