A Validity and Reliability of Learning Style Instruments Using e-LeS Online Web Based System

摘要

The reliability of an instrument developed to measure the learning styles is essential to find out learners' learning styles ability. An electronic learning style (e-LeS) was developed to measure students' individual learning styles (LeS). The purpose of this research was to produce empirical evidence of validity and reliability by using Rasch Model of 6 learning styles constructs; Competitive, Collaborative, Avoidant, Participative, Dependent and Independent. A survey was conducted to 185 postgraduate students from a Malaysian Institute of Teachers Training (ITT). Statistical analysis using Winsteps software was selected to measure the validity and reliability of the 60 items and the results showed the reliability of LeS items was between 0.96 and 0.99. Results from the analysis showed that the separation index items were all above 2 and values of the polarity items indicated all positive values. Infit and Outfit MNSQ ranged 0.6 to 1.4 were produced for the purpose of removing and retaining items. Finally Rasch Model analysis has dropped 7 items from the 60 items. The Rasch Measurement Model has proven highest degree of validity and reliability in measuring LeS items of learning styles.
