Abstract

Background: The International Baccalaureate Middle Years Programme (IBMYP) aims to produce a holistic transformation with creative and critically minded students. However, very little attention has been paid to the development of an instrument to measure the IB learner profile with good psychometric properties. Purpose: This study aims to develop an instrument with good psychometric properties, based on the Rasch measurement model and confirmatory factor analysis. Methods: The study consists of two phases of pilot and field studies involving 597 year four students from IBWS MOE. Results: The findings from the Rasch measurement model analysis have shown that 54 items meet the criteria of the item fit, unidimensionality, and reliability index. Meanwhile, confirmatory factor analysis found that 44 items have shown a valid item fit index. Conclusions: The combination of both analyses has shown the strength of 10IBLP-I psychometric properties that cover the aspects of validity and reliability. The findings also provide an implication to the theory, with empirical evidence that the IB learner profile consists of 10 constructs. Besides, the evidenced 10IBLP-I comprises good psychometric properties, which can be used to measure the level of IB learner profile among IBWS MOE students to assess the effectiveness of the implementation of IBMYP in Malaysia.

Highlights

10IBLP-I instrument to measure the level of International Baccalaureate (IB) learner profile among International Baccalaureate World School (IBWS) MOE students, and (2) to examine the 10IBLP-I psychometric properties based on the Rasch measurement model as well as confirmatory factor analysis
This article aims to identify whether the developed 10IBLP-I instrument has good psychometric properties based on the Rasch measurement model and confirmatory factor analysis
The findings proved that a combination of the Rasch measurement model and confirmatory factor analysis can produce robust and consistent items with clear structures, and correspond to each construct

Summary

Introduction

In facing fast-growing and uncertain global challenges, the fourth target in the sustainable development goals (SDG) focuses on developing superior human capital that can be a driver for the nation’s progress and development. This can be achieved through global citizenship education that trains students to understand and respect each other’s differences, which can contribute to world peace. Purpose: This study aims to develop an instrument with good psychometric properties, based on the Rasch measurement model and confirmatory factor analysis
