Development and Validation of Chemistry Virtual Test Based Multiple Representations
The purpose of this study was developing and validation virtual test based multiple representations to facilitate students to understand the questions that assess students’ decision-making competence of buffer solution. This research was conducted using the method development and validation. The participants were 136 high school students who take science class. Data obtained were content validity, reliability, item difficulty index, discrimination index and readability of virtual test that has developed. This study also compared the item difficulty and readability between virtual test and paper and pencil test. The results showed that the virtual test had CVI’s value was 0.71, the Cronbach's Alpha value was 0.925 which was showed that the reliability with included in “very good” category, the item difficulty index was moderate categories and the readability of virtual test was higher than paper and pencil test. It could be concluded that the virtual test that had developed was feasible to use and could facilitate students in understanding the questions that assess students’ decision-making competence of buffer solution.
