Assessing the validity of the Pancasila Student Character Learning Environment Inventory instrument

Abstract

The purpose of this study was to test the Pancasila Student Character Learning Environment Inventory Instrument for high school students using the Multi-Item Response Theory (MIRT) as a measurement model. An analysis was conducted to find proof of validity and reliability, as well as the level of difficulty of the items and any signs of item bias. There was a pilot study with 330 students from 7 high schools (4 public high schools and 3 private high schools) to try the instruments. The MIRT model analysis shows that 6 of the 106 items have a negative total correlation of items, and 1 item has a different item function (DIF) that needs to be calculated and is not part of the second empirical test. The Multidimensional Graded Response Model (MGRM), the Multidimensional Partial Credit Model (MPCM), and the Multidimensional Generalized Partial Credit Model (MGPCM) were all tested. The Pancasila Student Character Learning Environment Inventory tool passed the psychometric testing that was conducted using MIRT model analysis. The tests were meant to show that the scale was accurate and reliable, to check for multidimensionality, to examine how difficult the items were and how well the respondents performed, and to identify any item bias (DIF).
