Abstract

One of the 21st century abilities that must be mastered by students is the ability to think critically. To determine the level of successful students in developing critical thinking skills, an instrument is needed that can measure the critical thinking ability. The aimed of this study is to analyze the instrument of critical thinking skills. This research is quantitative methode. Data of critical thinking skills was obtained from 269 students on fifth grade from five elementary schools in Jakarta. The data was analyzed by rasch models using winstep version 4.4.3 software. The findings of the pilot study found that the reliability obtained based on the Cronbach Alpha is 0.98, so this value shows instruments used are in very good condition and effectively with a high level of consistency. Reliability of item is 0.99, while the separation of the item is 9.70 and this value can still be used because it shows that the entire item. The respondent was 0.72. While the separation of respondent is 1.62, it indicates in good condition and acceptable. The results showed that all items had a high value of Point Measure correlation which indicated that items could distinguish the ability of respondents. Instruments are valid and reliable can be used for further research
