Abstract
Malaysia is considered one of the developing countries undergoing rapid economic development over the past five decades. As a developing country with a rapidly growing population, providing the citizens with comprehensive and updated knowledge is crucial for the country, particularly in vocational training. A number of vocational and technical training have been developed. However, the success of vocational education relies on the capability of instructors or teacher’s approach to achieve the goals. It is important to create appropriate method that take into consideration their students’ learning styles to get better outcome. Therefore, the purpose of this paper is to develop vocational learning styles instrument. Empirical evidence on the validity and reliability of modified items has been done. A survey of 57 Electrical Technology students were distributed. The Rasch measurement model was used to examine the functional items and detect the item and respondent reliability and index separation, the polarity of item, measuring the fit of item in measuring the construct and standardised residual correlation values.
Highlights
Items adequacy in the instrument, to identify the item’s fit in the definition of learning style of the instrument and lastly to identify dependant items based on standardizes residual correlation values
According to (Yusoff et al, (2018), the researchers conducted four diagnoses to perform the item functional inspection, namely item reliability and separation index, detecting the polarity of an item to measure the construct based on PTMEA CORR, testing the suitability of an item by measuring the construct and lastly to determine the dependant item based on the standardised residual correlation values
The separation index indicates that the value that is accepted by Linacre, (2012) and on Bond and Fox, (2007) is more than 2.0. the reliability of person was 0.87, while the separation index of person was 2.64
Summary
This research is to determine the validity, and reliability of the 35 items in the four (4) constructs of vocational learning style in accordance with the Rasch measurement model’s procedures of the reliability analysis of an item. This study is aimed to fulfil the development an instrument of vocational learning styles. This study is driven by the following research objectives which are to identify the items and person reliability and separation index in the instrument, to identify the polarity of
