Ramadhaningtyas, Dwi Ajeng (2018) Item Response Theory (IRT) Vs Classical Test Theory (CTT) : Skala Identitas Etnis Versi Forced Choice. Sarjana thesis, Universitas Brawijaya.
Abstract
Penelitian ini bertujuan untuk melihat perbandingan performa antara pendekatan psikometrik Item Response Theory (IRT) dan Classical Test Theory (CTT) dalam menganalisis skala identitas etnis versi forced choice. Teknik analisis yang digunakan dalam penelitian ini yaitu, Corrected Item Total Correlation (rit), Kuder-Richardson 20 (KR-20), Standard Error of Measurement (SEM) untuk CTT dan 3 model parameter logistik, Standard Error of Measurement (SEM), Item Characteristic Curve (ICC), Item Information Function (IIF) untuk IRT. Subjek dalam penelitian ini berjumlah 443 yang merupakan remaja berusia 12 hingga 15 tahun dari SMP Laboratorium Universitas Negeri Malang. Penelitian ini menggunakan metode kuantitatif. Pengumpulan data dilakukan sebanyak satu kali dengan interval satu minggu, administrasi tes menggunakan skala identitas etnis versi forced choice yang dikembangkan oleh Safitri (2017) dan Saputra (2017). Skala identitas etnis versi forced choice memiliki tiga dimensi yang bersifat multidimensional with uncorrelated dimensions yaitu dimensi eksplorasi, dimensi komitmen dan dimensi afirmasi. Hasil analisis karakteristik aitem pada dimensi eksplorasi dan dimensi komitmen memiliki hasil yang sebanding menggunakan CTT dan IRT, sedangkan pada dimensi afirmasi aitem yang dinilai tidak memenuhi kriteria parameter
English Abstract
This research aims to comparing Item Response Theory (IRT) and Classical Test Theory (CTT) in analyzing ethnic identity scale forced choice version. The analyze technique used in this research are Corrected Item Total Correlation (rit), Kuder-Richardson 20 (KR-20), Standard Error of Measurement (SEM) for CTT and two parameter logistic models, Standard Error of Measurement (SEM), Item Characteristic Curve (ICC), Item Information Function (IIF) for IRT. Sample in this study amounted to 441 who are adolescents in SMP Laboratory State University of Malang aged 12 to 15 years. This research uses quantitative method. The data were collected once in one week interval, the test administration using the forced choice version of ethnic identity score developed by Safitri (2017) and Saputra (2017). The ethnic identity scale forced choice version has three dimensions that are multidimensional with uncorrelated dimensions, namely exploration dimension, commitment dimension and affirmation dimension. The result of analysis of item characteristics on exploration dimension and commitment dimension have comparable result using CTT and IRT, whereas in the dimension of affirmation of item which is considered not to meet the criterion of
