- Abstract
Verbal representation ability is an important part of learning physics at school and is also useful for adapting to the environment. The verbal representation ability is also a need for education in the 21st century, so having this ability can help students to understand the physics language, physics quantity, and physics concepts. This research purposes to determine the feasibility of developed test instruments in terms of validity and reliability. The test instrument developed as a diagnostic test instrument in the form of multiple-choice with a total of 27 questions. The content validity analysis of the test instruments was carried out using the Aiken’s V Coefficient. The validity and reliability of empirical evidence from the test instruments were estimated using Item Response Theory (IRT). The results of this research indicate that the developed test instrument is feasible to be used as an instrument to diagnose the verbal representation ability with valid results according to the Aiken’s V coefficient between 0.81 to 1.00 and can be relied on with a reliability value according to IRT of 0.96 whereas developed questions are declared reliable according to IRT if used by students with abilities ranging from -2.0 to 1.9 on a logit scale.
