Abstract
A scientific explanation is one of the main goals in science learning, including physics. But, nowadays it is still rare that instruments can develop the scientific explanation skills, so it requires a specific test to measure it. This research aims to develop scientific explanation skills test instrument on the kinetic theory of gases material named KTG- SESC (Kinetic Theory of Gases-Scientific Explanation Skills Checker). The test instrument was prepared based on the adaptation and modification of Chaimalas scientific explanation skills test (2009). The method used is a method of research and development of instructional models 4D (define, design, develop and disseminate) is constrained only to a point 2D (define and design). The questions have already been developed as many as six questions in the form of essays. With the purpose of, it can be seen categories of students explain scientifically through the answer. Based on the trial, scientific explanation instruments have been high category reliability and good validity. Through the define and design stage, a scientific explanation skills test instrument for high school students has been developed in the kinetic theory of gases based instrument of SESC test by Chaimala.
