Abstract
Learning science in the 21st century promoted the active role of students in gaining competence. Science education aims to help students understand scientific knowledge and develop students ability to scientific process skills by inquiry. This study aims to implement and create the instrument of science process skills tests on cellular living system organization matter, explicitly designed for secondary students. The indicators developed include formulating hypotheses, communicating, applying concepts, asking questions, observing, planning experiments, using laboratory tools, classifying, and interpreting data. The research method used is research and development (R&D) with the ADDIE model. The steps of this research are theoretical construction, determining the purpose of the assessment, constructing indicator items, compiling the items, expert judgment, instrument revision, field trials and finalization of the instrument. The Science Process skills test consisted of 27 multiple-choice questions. The subject was 30 secondary school students. Evidence of the validity and reliability of the tests are presented. The conclusion is that the science process skills test instrument is theoretically and empirically valid and reliable.
