Students' Moral Behaviour Inventory Development and Validation: A Rasch Analysis

摘要

In this study, an instrument was developed to measure the level of students' moral behaviour based on the Malaysian Moral Education Syllabus. Samples are from 60 secondary school students; aged from 14 to 17 years old, from a middle school in the Tuaran district, Sabah. The Students' Moral Behavior Inventory had 108 items, with a four-point rating scale (never, seldom, often, always) questionnaire that assessed seven learning areas (self-development, family, environment, patriotism, human rights, democracy and, peace and harmony). This paper reports the analysis of the quality of each of the items in the instrument using Rasch Model. Person reliability (0, 97) and item reliability (0.95) are excellent. The infit and outfit mean square for all the items were between 0.50 and 1.50, except for 10 items that needed to be checked and modified. The principal component analysis residual showed that there is no noticeable secondary dimension. Summary statistics show good reliability and separation while the person separation and reliability are weak. Category structure is OK. The stability of Students' Moral Behavior Inventory needs to be tested again after the modification of the misfit items.
