Investigating Measurement Invariance of Learning Model Towards Science: PISA 2015 Sample

In this study, the learning model toward science in PISA 2015 was examined in terms of measurement invariance across Turkey and Singapur samples by cultural invariance and in Turkey sample by gender invariance. For this purpose, multiple group confirmatory factor analysis based on the structural equation model was applied in LISREL 8.80 program. Results of the analyze showed that the model provides configural and metric invariance between gender in Turkey sample but scalar invariance had failed to ensure. The model was ensure only configural invariance across Turkey and Singapore samples
