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.

摘要

背景

国际文凭组织中学项目（IBMYP）旨在培养具有创造力和批判性思维的全面发展的学生。然而，很少有人关注开发具有良好心理测量学特性的衡量国际文凭学习者形象的工具。

目的

本研究旨在基于 Rasch 测量模型和验证性因素分析开发具有良好心理测量学特性的工具。

方法

研究包括两个试点和现场研究阶段，涉及来自 IBWS MOE 的 597 名四年级学生。

结果

Rasch 测量模型分析的结果表明，54 个项目符合项目拟合、单维性和可靠性指数的标准。同时，验证性因素分析发现 44 个项目具有有效的项目拟合指数。

结论

两种分析的结合显示了 10IBLP-I 心理测量特性的优势，涵盖了有效性和可靠性两个方面。研究结果还为理论提供了启示，实证证据表明，IB 学习者形象由 10 个结构组成。此外，经过验证的 10IBLP-I 具有良好的心理测量特性，可用于衡量 MOE IBWS 学生的 IB 学习者形象水平，以评估马来西亚实施 IBMYP 的效果。
