This research is part of the standardization of the Students' Coping Strategy Scale (SCSS). This study aims to reveal the content validity, empirical validity, and reliability of the SCSS. The non-test instrument consisting of 42 statements from three dimensions: problem-focused coping, emotion-focused coping, and seeking social support. Content validity analysis was carried out by experts to obtain Gregory's content validity coefficient, while the empirical validity and reliability analysis by empirically testing the instrument on 211 respondents and analyzed using the Rasch model approach. The results show that Gregory's content validity coefficient is 0.714, so it needs improvement on some items that are considered unsuitable. Empirical validity analysis using WINSTEPS software shows that three items do not fit the model. The reliability coefficient of the SCSS is 0.99. Thus, the remaining 39 items are appropriate to be used to measure students' coping strategies.

Tujuan dari penelitian ini untuk menghasilkan produk Fluids Assessment (FAss) berdasarkan Taxonomy of Introductory Physics Problems (TIPP) yang layak pada materi fluida dinamis. Analisis validitas menggunakan pendekatan Item Response Theory (IRT) dengan satu Parameter Logistik (PL) yakni parameter tingkat kesukaran atau lebih dikenal dengan Rasch Model. Selain itu, produk yang dihasilkan dianalisis dengan pendekatan teori klasik untuk melihat daya beda dan efektivitas distraktor. Penelitian ini merupakan Research and Development dengan mengadaptasi model pengembangan Borg and Gall. Hasil penelitian menunjukkan bahwa 34 butir soal dinyatakan valid menurut para ahli dengan analisis Content Validity Ratio (CVR). Sedangkan hasil analisis berdasarkan Rasch Model menunjukkan 17 butir soal valid dan reliabilitas soal diperoleh sebesar 0,90 dengan kategori baik. Dapat disimpulkan bahwa Fass memiliki tingkat kesukaran relatif sedang, daya beda yang baik, dan pengecoh yang berfungsi. Hasil implementasi menunjukkan bahwa sebagian besar siswa mengusai setiap level TIPP kecuali level 3a, 4d dan 4c yang berkaitan dengan matching, investigating, dan experimenting. The purpose of this study was to produce a Fluids Assessment (FAss) product based on an appropriate Taxonomy of Introductory Physics Problems (TIPP) on dynamic fluid material. Validity analysis uses the Item Response Theory (IRT) approach with a Parameter Logistic (PL), which is a difficulty level parameter or better known as the Rasch Model. Also, the resulting product was analyzed with a classical theoretical approach to see the difference in distinguishing power and effectiveness of the distractor. This research is a Research and Development by adapting the development model of Borg and Gall. The results showed that 34 items were declared valid according to experts with Content Validity Ratio (CVR) analysis. While the analysis based on the Rasch Model shows that 17 items are valid and the reliability of the questions is 0.90 in the good category, it can conclude that the Fass has a relatively moderate level of difficulty, a good difference in power, and a deception that works. The results of the implementation showed that most students mastered every level of TIPP except level 3a, 4d, and 4c relating to matching, investigating, and experimenting.

The Rasch Model

The present study addressed the issue of reliability and validity of scale through the comparison between the traditional method and the Rasch model, which is seen by statisticians as the best method to psychometrically validate the scale and test its properties. Researchers have demonstrated the failure of traditional statistical methods to take into account the characteristics of the items and people when testing the reliability of the scale as well as respondents. They usually turn to alpha Cronbanch to examine the internal consistency of the scale without taking into consideration that alpha Cronbanch has been affected by external factors such as the length of the scale. However, the Rasch model that is relatively considered to be modern statistics, is not affected by external factors especially the length of the scale, even a short scale might be more reliable than the long one. Moreover, the Rasch model can also be used to investigate various types of validities such as content validity, construct validity, and criterion validity. Interestingly, the Rasch model is also a powerful statistics tool used to determine the contribution of the items and people in the total reliability of the scale. For example, the variable map is used to examine the extent to which the items adequately target the respondents taking into account the difficulty of items and ability of the subjects. Nevertheless, the traditional methods normally calculate the uniqueness of the scale by focusing on the sum of squares and these methods do not offer standard errors for each item to determine the accuracy of the measurement. Hence, the researchers suggested in this paper that favorability of the Rasch model in testing scales’ reliability and validity was recommended compared to conventional statistical methods.
