Abstract

This pilot study aims to produce empirical evidence regarding the validity and reliability of instrument of the perception of vocational college diploma students towards the Outcome Based Education (OBE) approach. Validity and reliability were analysed using Rasch Model Measurement assisted by Winsteps 3.72 software. This research instrument contained 26 items and was distributed to 60 diploma students of vocational college at the Northern Zone. Validity analysis of the instrument was done through four functional testings. For reliability and separation of respondents, it was found that the individual reliability value was 0.91, while that for items demonstrated an item value of 0.94 and item separation index of 3.90. Results from the analysis of polarity item found that 25 items had a positive PMC value between 0.52-0.83. Meanwhile, analysis on item fit found 23 items with an outfit mean-square value between 0.41 and 1.24. This situation suggested three items that require attention. In the analysis on local dependence that determines dependent items based on the standardised residual correlation value, it was shown that the correlation value for the items used did not overlap with that of other items. These findings provided the evidence that the instrument of perception of vocational college diploma students on OBE approach has a high level of validity and reliability to be used in actual studies.

Highlights

Outcome Based Education (OBE) is an educational approach that focuses on the empirical characteristics of performance and achievement
The process of removing and refining items were carried out with reference and taking into account the views and evaluations of experts. The results of this pilot study found one item to be removed while the other three items were purified. Based on this pilot study, it can be explained that the validity and reliability of the instrument of students' perception of OBE approach has a quality that can be used for actual study
This pilot study is an initial step in assisting researchers to identify the perception of vocational college diploma students from the context of their readiness and views on the OBE approach

Summary

Introduction

Outcome Based Education (OBE) is an educational approach that focuses on the empirical characteristics of performance and achievement. In 2007, OBE was compulsory in the Malaysian Institutions of Higher Learning. The OBE approach was only widely used in vocational colleges since 2016. The debate on issues in the implementation of OBE was seriously discussed by all parties, especially in the Vocational Technical Education and Training Division. The use of OBE is intended to meet the standards in ensuring that diploma programs in Vocational Colleges are recognised by the Malaysian Qualifications Agency (MQA). The accreditation from professional bodies offer significant recognition to the schools and/or programmes for their appropriate and effective assurance of learning process (Sun & Lee, 2020)
