The Development of Problem-Based Learning Test Instruments for the High School Physics Problem Solving Skills

Abstract

Problem solving skills are an important part of physics learning in schools and is also useful for adapting to the environment. Problem solving skills are also a demand for education in the 21st century, so having this skills can help to compete in gaining experience in this all-modern world. This study aimed to determine the feasibility of the developed test instrument in terms of content validity and reliability. The test instrument developed was in the form of multiple choices with a total of 25 questions. The analysis of content validity of the test instrument was conducted using the Aiken's V Coefficient. The empirical validity and reliability of test instrument were estimated using the Classical Test Theory (CTT) and Item Response Theory (IRT). The results of this study showed that the test instrument developed was valid with Aiken's V Coefficient ranging between 0.76 to 0.95 and reliable with a reliability value according to CTT of 9.5, while the developed questions were stated reliable according to the IRT if used by the students with the ability ranging between -1.2 to 3.8 in logit scale. Based on the results of the study, the instrument developed was feasible to be used as an instrument for testing problem solving skills.
