Content Validity Analysis of the PISA-Science Literacy Test for SMP Unismuh Makassar Students on the Topic of Optical Instruments

Abstract

This research aims to analyse the content validity of the PISA-science literacy test on the topic of optical instruments. The design of this test aims to measure the scientific literacy abilities of eighth grade students at SMP Unismuh Makassar. The design of this test was developed based on core competencies and basic competencies and adapted to scientific literacy indicators, especially in science learning material on the topic of Optical Instruments which includes aspects of explaining scientific phenomena, evaluating and designing scientific research, as well as aspects of interpreting scientific data and evidence which are then formulated into 5 questions in the form of essay questions. The method used in this research is the descriptive analysis method as content validity analysis based on Lawshe’s formula calculations which have become known as the CVR and I-CVI coefficients. Content validity data was obtained from validation results from five experts with different expertise backgrounds in the field of science education. The expert validation results were then analysed to determine the level of content validity of the PISA-science literacy test which was developed using the Lawshe’s formula. The research results showed that the CVR coefficient value obtained was 0.99 with a total of five expert judgments, so it was declared accepted. Further analysis was obtained by obtaining an I-CVI coefficient value of 0.99 with the appropriate category. Based on the CVR and I-CVI coefficient values, it can be concluded that the content validity of the PISA-science literacy test developed is in the appropriate category and supports the entire content of the test as a whole.
