Abstract
This research is part of the development of the Physics Adaptive Test instrument to measure the Higher Order Thinking Skills (HOTS) of eleventh-grade high school students. In this section, the purpose of this study is to analyze the content validity of the instrument. The developed instrument consists of 20 multiple-choice questions based on the levels of understanding higher-order thinking skills. Furthermore, this instrument was assessed qualitatively and quantitatively by 3 experts with assessment aspects including: 1) The questions match the HOTS indicators, 2) The stimulus/stem fits the questions, 3) The questions are clearly formulated, and 4) The problem description is clear and unambiguous. The method used in this research is a descriptive analysis method for content validation based on Aiken^s Formula. Data for content validation were obtained from 3 experts in the field of physics. Based on the results and discussion, it can be concluded that the 20 items of the Physics Adaptive Test instrument to measure the higher-order thinking skills of eleventh-grade high school physics students are declared valid.
