Abstract
Scientific communication skills are one of the important assessments in 21st-century learning, including in science learning. One form of scientific communication is scientific argumentation. Scientific argumentation skills can be trained from high school to college level. This research is concerned with the development of scientific argumentation test. The development research of Plomp model is used. This article is limited to the design stage and the validity of the test instrument. The scientific argumentation instrument was developed with five essay questions. Problems are made with fluid mechanics material. Five experts in the field of fluid mechanics carried out proof of the validity of scientific argumentation instruments and continued with calculations using the Aiken V index formula. The validation results showed that all five items were valid with an average Aiken index of 0.87. Questions that have been validated are ready to be tested.
