【 摘 要 】

Along with numerous instruments developed and used in science education researches, some of those instruments have been translated to local language in the country where the instruments were used. Most of researchers that used those translated instruments did not report the quality of those translated instruments. One of the instruments is the Scientific Literacy Assessment (SLA) including the Science Motivation and Beliefs (SLA-MB) as part of the SLA. In this study, the SLA-MB has been translated into Indonesian Language (Bahasa). The purpose of this study is to investigate the SLA-MB instrument that has been translated to Indonesian language from the view of dimensionality, reliability, item quality and differential item functioning (DIF) based on IRT-Rasch analysis. We used Conquest and Winstep as the program for IRT-Rasch analysis. We employed quantitative research method with school-survey on this study. Research subjects are 223 Indonesian Middle school students (age 13-16), with 64 boys and 159 girls. IRT-Rasch analysis of the SLA-MB Indonesian version indicated that a three-dimensional model fit significantly better than one-dimension model, and the reliability of each dimensions are about 0.60 to 0.82. As well as those findings, fit values of all items are acceptable, moreover we found no DIF for all of the SLA-MB items. Overall, our study suggests that Indonesian version of SLA-MB is acceptable to be implemented as research instrument conducted in Indonesia.
