EXAMINING THE RELIABILITY AND VALIDITY OF RESEARCH INSTRUMENTS USING PARTIAL LEAST SQUARES STRUCTURAL EQUATION MODELING (PLS-SEM)

摘要: Understanding teacher’s behavioural intention in teaching science becomes a foundation to improve teacher education programme. Prior the evaluation of interrelation between self-efficacy beliefs, motivation, attitudes towards science, and this research examines reliability validity instruments used measure constructs. ‘Science Teaching Efficacy Belief Instrument-Form B’ (STEBI-B) was pre-service teachers’ beliefs. ‘Work Tasks Motivation Scale for Teachers’ (WTMST) motivation. ‘Dimensions Attitude Science’ (DAS) whereas ‘Behavioural Intention Scale’ among teachers. Partial Least Square-Structural Equation Modelling approach evaluate instruments. Research findings concluded all are valid reliable be future research.
