<![CDATA[There is limited literature reporting on the use of the Rasch model in analyzing the conceptual understanding of student temperature in Indonesia. There are 58% of Physics Education undergraduate students experience misconceptions on the topic of temperature. Therefore, this study aims to analyze students’ conceptual understanding using a two-level diagnostic instrument. Students’ conceptual understanding was administered through a survey method using a two-level misconception diagnostic instrument. The survey was conducted on 26 students (31% boys and 69% girls) ages ranging from 16 years to 19 years at a public high school. Students’ conceptual understanding of the temperature material was administered using six diagnostic items and analyzed using the Wright map. Data collection has been done online using a Google form distributed through the class WhatsApp group. Data analysis has been carried out in two stages namely, coding students’ answers, and analyzing students’ conceptual understanding. The analysis results showed a shift in the level of conceptual understanding of 50% of students. So, the Wright map provides a visualization of shifts in the level of students’ conceptual understanding of the topic of temperature.]]>
