Validation of the Instruments Measuring Team-based Learning Strategy

Abstract

The main objective of this study is to analyse the reliability and validity of psychometric properties of two instruments: Team-Based Learning Student Assessment Instrument (TBL-SAI) and the Team Performance Survey (TPS). A 33-item TBL-SAI and an 18-item TPS were administered to investigate undergraduate students’ perception of TBL and PBL incorporated in the medical terminology course were recruited. A Cronbach’s alpha test and a principal component analysis were administered in establishing the reliability and validity of the instruments. The study’s results showed that Cronbach’s alpha values were 0.88 (TBL-SAI) and 0.98 (TPS), indicating high levels of reliability of both instruments. PCA also discovered that the TBL-SAI scale extracted nine components with all items’ factor loading greater than 0.60, except for the first and second items in the accountability domain, and the third item in the learning preference domain. Meanwhile, the TPS scale extracted one component with all items loaded more than 0.6, suggesting both TBL-SAI and TPS scales were appraising the factors intended to be measured. Both TBL-SAI and TPS demonstrated acceptable levels of internal consistency and construct validity in assessing students’ perception of TBL and PBL in the course.
