Development of m-learning implementation instrument based on competency-based education: rasch analysis

Abstract

This study was undertaken to produce empirical evidence of validity and reliability of the m-learning implementation instrument constructed based on competency-based education using rasch model analysis. It aims to validate the instrument by using tests in rasch analysis such as item polarity, fit measure, principal component analysis and reliability. The questionnaire was distributed to 55 teachers teaching upper secondary vocational programme (pvma) in the states of johor and selangor. Analysis of the rasch measurement model was performed using winsteps software version 3.69.1.11. The final instrument recorded 47 items that can be used to measure the eight constructs of the study. This study shows that the rasch measurement model can help researchers build a good instrument as the items constructed offset psychometric standards.
