Development of PISA-based test on mechanical wave material in senior high school

Abstract

This study aims to develop a PISA-based test on mechanical wave material in high school in accordance with good test qualification standards in terms of validity, reliability, level of difficulty, discriminatory power and effectiveness of distractors. The type of research is development research, using the ADDIE model. The data analysis technique used is qualitative and quantitative. The results of qualitative analysis, the quality of the PISA-based test is very good with a percentage of validity of 84.75% based on the results of validation by 5 experts who are reviewed in terms of material, construct and grammar. Quantitative analysis of the quality of the PISA-based test are good. Analysis of 38 items in the small group test obtained 36 items accepted and 2 items rejected. The large group test obtained: (1) 32 valid items (88.89%), 4 invalid items (11.11%). (2) the reliability of the tests is included in the Very Good category with a value of 0.839. (3) 4 (11.11%) questions in the easy category, 30 (83.33%) questions in the medium category and 2 (5.56%) in the difficult category. (4) The discriminatory power of questions obtained 1 (2.78%) questions in the very good category, 31 (86.61%) questions in the good category and 4 (11.11%) questions in the bad category. (5) 32 (88.89%) items are effective and 4 (11.11%) items are ineffective. The items received were 30 (83.33%) questions, 2 (5.56%) items revised, and 4 (11.11%) items rejected.
