Science learning achievement Natural Knowledge in the independent curriculum includes science process skills and critical thinking. This overlaps with 21st century skills and curriculum targets in several developed countries. The preliminary study shows the low achievement of science process skills and critical thinking in physics learning. This study aims to develop a science process skills test instrument for learning physics. The development of the test is limited to physics subjects on renewable energy. Each aspect of science process skills and critical thinking is further elaborated into 5 indicators, then developed into 10 items each. Instruments that have been validated with expert justification. then tested on 35 school students High School to then be tested for reliability, level of difficulty and question discrimination. Validation results from 3 experts stated that the scientific process skills test instruments and critical thinking skills that had been compiled fulfilled content validity and could be used. However, there were editorials that needed to be improved. Item reliability testing was carried out by alpha conbrach calculations using the SPSS program indicating the level of category instrument reliability. tall. Easy and medium level of difficulty category. The distinguishing power of most of the categories is very good. The conclusion based on the results of the research conducted is that the test instruments for science process skills and critical thinking in physics learning of renewable energy chapters that are developed are feasible to use with test instruments in the form of descriptions with each indicator of science process skills and critical thinking skills. as many as 5 indicators out of six indicators, further researchers can develop this test instrument more fully. © 2024 Author(s).
