Abstract

This study aims to develop a HOTS-based test instrument in measuring students' critical thinking skills on the material of quantities and units at SMAN 2 Rambah Hilir which has met the criteria for testing the instrument's feasibility including content validity, item validity, reliability testing, level of difficulty, discriminating power, and student response test. This research is a research development or Research and Development (RnD) using the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) model. This research was conducted at SMA Negeri 2 Rambah Hilir with the research subjects of class X MIPA SMA Negeri 2 Rambah Hilir. Based on the data obtained from content validity with the Lawshe technique, 10 questions were obtained that could be used. Meanwhile , from testing the validity of the items , there are 8 valid questions and 2 invalid questions . In the reliability test obtained a value of 0.543390 with moderate correlation criteria. For the level of difficulty, scores ranged from 0.297 to 0.70 with the criteria that 1 item was said to be easy, 1 item was said to be difficult, and 8 items were said to be moderate . While different power derive a value of -1 , 8 - 2.5 with a category 2 a matter of saying ugly and the two problems said to be good at all. Meanwhile, to test students' response was obtained by 78 , 1 % in both categories. The conclusion from the overall test results is that the HOTS-based test instrument is feasible to use to measure critical thinking skills.Keywords : Development of Test Instruments, Critical Thinking Skills, Quantities and Units

Abstract

This study aims to measure the effect of using interactive e-books in enhancing students' mathematical representation skills on optics material in high school. Mathematical representation involves students' ability to use mathematical symbols, graphs, and formulas to solve physics problems, particularly in the concept of optics, which is often considered abstract. The research method used was a quasi-experiment with a pretest-posttest control group design. The sample consisted of two classes: an experimental class using interactive e-books as learning media and a control class using conventional methods. The results showed an improvement in mathematical representation skills in both classes, with the n-gain value of the experimental class being 0.604 and the control class being 0.557, both in the medium category. However, the experimental class demonstrated a more significant improvement compared to the control class, indicating that interactive e-books are more effective in helping students deeply understand optical concepts. The interactive features in the e-book, such as simulations and animations, provided a more engaging learning experience and helped students visualize abstract concepts. In conclusion, the use of interactive e-books has a positive impact on improving students' mathematical representation skills and can be considered an effective alternative learning medium, especially for science subjects that require better visualization and conceptual understanding.
