Abstract

The purpose of this study was to develop a higher order thinking skill (HOTS) based test instrument on salt hydrolysis for senior high school students. The type of research used is Research and Development (R&D) using the Plomp model which consists of three stages, namely Preliminary Research, Prototyping Stage and Assessment Phase. The test instrument was validated by 7 experts, namely 4 chemistry lecturers of FMIPA UNP, and 3 chemistry teachers using a validation questionnaire. The small group trial was carried out by 6 students and the field test was carried out by 26 students of Senior High School number 1 in Padang. The data analysis technique for content validity uses Lawshe's CVR and the construct validity uses the aiken’s formula. The results showed that the instrument developed had good characteristics in terms of logical validity with a content validity index (CVI) of 0.841 and a construct validity of 0.82. The reliability coefficient of 0.89 is very high. The analysis of discriminating power showed 16 items had very good distinguishing quality, 4 items had good distinguishing quality, 4 items had moderate distinguishing quality. The difficulty index for 88% of the questions is categorized as medium. The correlation of the item score with a significant total score was 21 items. The dictator function on all items is effective. The data obtained shows that the test instrument based on higher order thinking skills (HOTS) on salt hydrolysis material for senior high school students is valid and has good item quality.
