STRUCTURAL EQUATION MODELLING (SEM): OVERVIEW, APPLICATIONS, AND MISAPPLICATION IN SCIENCE AND TECHNOLOGY EDUCATION
Abstract
Structural Equation Modelling (SEM) has become an increasingly important
multivariate statistical technique in educational and social science research due to
its ability to model complex relationships among observed and latent variables
simultaneously. Traditional techniques such as multiple regression analysis and
analysis of variance (ANOVA) are limited to directly measured variables and are
less effective in handling measurement error, indirect effects, and complex model
structures. This paper provides a comprehensive overview of SEM with special
emphases on its conceptual foundations, common terminologies, types, and
implementation procedures. Special attention was also given to the distinction
between covariance-based SEM (CB-SEM) and variance-based SEM, also known
as partial least squares SEM (PLS-SEM), including their underlying assumptions,
objectives, and appropriate conditions for use. The paper further outlines the major
steps involved in SEM implementation which include model specification,
measurement model evaluation, and structural model assessment within the PLS
SEM framework. Most importantly, frequent misapplications of SEM in
educational researches were highlighted. This paper aims to guide researchers
toward more rigorous, theoretically grounded, and meaningful applications of SEM
in educational research.
