The procedures of carrying out factorial invariance to validate a construct were well developed to ensure the reliability of the construct that can be used across groups for comparison and analysis, yet mainly restricted to the frequentist approach. This motivates an update to incorporate the growing Bayesian approach for carrying out the Bayesian…

Using generalizability theory to evaluate the reliability of child and adolescent measures enables researchers to enhance precision of measurement and consequently increase confidence in research findings. With an observer-rated measure of child self-regulation, we illustrate how multiple sources of error variance (e.g., raters, items) affect the…

The Bologna Declaration brought reforms into higher education that imply changes in teaching methods, didactic materials and textbooks, infrastructures and laboratories, etc. Statistics and mathematics are disciplines that traditionally have the worst success rates, particularly in non-mathematics core curricula courses. This research project,…
