VALIDITY AND RELIABILITY INSTRUMENT OF SCIENTIFIC LITERACY PERFORMANCE ASSESSMENT IN PHYSICS TEACHING BASED ON STEM
Abstract
This research is part of the development of scientific literacy performance assessment based on STEM in teaching physics. The aim of this research is to reveal the validity (content and also empiric) and reliability of scientific literacy performance assessment instrument based on STEM. The kind of instruments were developed are observational sheet and multiple choice test. The content validity of observational sheet was revealed by used the Aiken’s V Coefficient. The content validity of multiple choice tests was revealed by used Content Validity Index (CVI) which proposed by Lawshe. The empirical validity and reliability of multiple choice tests was revealed by used Item Response Theory Analysis. The reliability of observational sheet was revealed by used ICC (Item Correlation Coefficient) Analysis. The results of this study are the validity from the contents and empirical trials from the developed instruments. The observation sheet from scoring rubric and self-assessment has been valid with Aiken’s V value that exceeds the standard of 0,75. The reliability of the scoring rubric has Alfa Reliability> 0.8 and Excellent of ICC. Validity values from The written test is shown with CVI of 1 and the MNSQ INFIT value which match to the Rasch model. Based on the TIC and SEM graphs, the written test is stated to be reliable for use in students with moderate to high categories (-0.7 to 6.7). STEM-based Science Literacy performance assessment with caloric material is appropriate to use.
