“…These results show a congruent relationship between people and items used in the study [18], [19]. The results of this test provide information that the research instrument is able to provide an assessment of the teacher's digital literacy ability [20]. Based on Rasch's analysis of the difference in digital literacy abilities between men and women, it can be seen in Figure 1.…”

Advances in technology and the implementation of online learning require all parties in educational institutions, especially teachers, to be able to use technology. Digital literacy skills are needed to support the learning process. The purpose of this study was to measure the digital literacy skills of teachers through the Rasch model from a gender perspective during the coronavirus disease 2019 (COVID-19) pandemic at Madrasah Aliyah Negeri Palembang, Indonesia. A quantitative research method using Rasch analysis was applied. The results showed that the ability of teachers in digital literacy can be categorized as very high (three people), high (28 people), moderate (63 people), and low (two people) and showed that there are no question items that only favor one of the genders. The results showed that the male teachers in this study had a lower level of digital literacy skills than the female teachers.

Information about score obtained from a test is often interpreted as an indicator of the student's ability level. This is one of the weaknesses of classical analysis that are unable to provide meaningful and fair information. The acquisition of the same score if it comes from a test item with a different level of difficulty, must show different abilities. Analysis of the Rasch model will overcome this weakness. The purpose of this study was to analyze the quality of the items by validating the national chemistry exam instrument using the Rasch model. The research sample was 212 new students of the Department of Chemistry at the State University of Medan. The data collected was in the form of respondent's answer data to the 2013 chemistry UN questions, which amounted to 40 items multiple choice and uses the documentation method. Data analysis technique used the Rasch Model with Ministep software. The results of the analysis show the quality of the Chemistry National Exam (UN) questions is categorized as very good based on the following aspects: unidimension, item fit test, person map item, difficulty test level, person and item reliability. There is one item found to be gender bias, in which men benefit more than women. The average chemistry ability of respondents is above the average level of difficulty of the test items

“…Items that do not fall within the scope of The Item Fit Index (Table 4) must be changed or removed in order to improve the item fit value (Sumintono & Widhiarso, 2015). (Yasin, Yunus, & Ismail, 2018). According to Boone (2016), if the ZSTD Outfit value is greater than 2.0 and the MEASURE value is high, there is a chance that a teacher with a background in quantum physics may not respond with caution to low-level items.…”

This study aims to determine the validity and reliability of Teacher Readiness to teach Quantum Physics (TRQP) instrument using Rasch Measurement Model. The TRQP was developed to measure the level of teacher readiness to teach quantum physics in secondary schools. TRQP consisted of 41 items containing three constructs namely: content knowledge, attitudes, and readiness. The research sample consisted of 30 Form Five Physics teacher from secondary schools in Sabah. The results of the validity analysis found that the polarity of the items through the PTMEA-CORR values showed that all 41 items were > 0.00 (+). Through item fit analysis, all items were retained because they met the requirements in one of the MNSQ, Outfit ZSTD, and PTMEA-CORR outfit ranges. In the Principal Component Analysis (PCA), the Raw Variance Explained by Measures value of 40.6% and the Unexplained variance value in the first to fifth contrast below 15% indicates that the instrument has a strong dimensional dimension and has high construct validity. The reliability of Cronbach Alpha (KR20) showed a value of 0.87 (high), item reliability of 0.88 (very good), and person reliability of 0.81 (good) with separation item value of 2.73 (good) and separation person value of 2.04 (good). In conclusion, TRQP has good validity and reliability in measuring the level of teacher readiness to teach quantum physics in terms of content knowledge and attitudes among Form Five Physics teachers in secondary schools.
