Social science research with a quantitative approach should use the appropriate scale of measurement to interpret a variable correctly. There are two types of measurement scale that is category scale and numerical scale. Category scale is for nominal and ordinal data, while the numerical scale for an interval and ratio data. In mathematical analysis, numerical scale indicates the exact measurement and more precise definitions of certain variables. Category scale is only used to classify a variable. However, Likert scale which is used for ordinal data are often used as a measurement tool in social science research. Therefore, the Rasch model analysis that can change the nominal and ordinal data to interval and ratio data was used in this study. Here, it was used to evaluate the validity and reliability of authentic learning instrument at Malaysian Polytechnics. Validity of instrument was seen by unidimensional analysis through principal component analysis method. Reliability of instrument was seen by summary statistics, variable map and item fit table. The findings show that the authentic learning instrument at Malaysian Polytechnics has high validity and reliability.

In the midst of the Fourth Industrial Revolution, Malaysia is one of the countries that is striving to advance, particularly in the building industry. The adoption of the Industrialized Building System (IBS) in Malaysia signals that the nation is prepared to accommodate significant shifts in its commercial construction sector. However, the A-frame IBS panel holder had a problem in terms of the limited space that was provided by the conventional method. Additionally, there was a possibility that the precast panel could have been of poor quality while it was being transported to its final location. The aim of this paper is to proposed the M-framed design holder to optimise the quantity of the IBS module transportation and subsequently, reduce the cost of transportation. The objective of the study is to identify the issues in the Aframe IBS panel transportation and assembling method. In order to achieve the objective , a thorough review of the relevant literature on the transportation method in the IBS and a simulation has been adopted. The results shows that the proposed M-framed design was able to optimize the quantity of IBS panel been transported and consequently reduce the cost of transportation.
