Structural equation modeling of relationship between self-directed learning, learning styles and learning strategies with academic achievement of English language in public pre-university schools in Isfahan

The purpose of this research was to Structural equation modeling of relationship between self-directed learning, learning styles and learning strategies with academic achievement of English language in public pre-university schools in Isfahan. This descriptive research was causal-correlation. 370 students were selected by stratified random sampling (168 boys and 202 girls). The research instruments were self- directed learning, learning styles, and learning strategies questionnaires. By Spss 18, correlation matrix was used to analyze data, and AMOS was used to determine the goodness-of fit of causal model. The results showed that there is a relationship between learning styles, learning strategies and educational achievement. The designed model in the research was goodness-of fit based on structural equation models. The indicators were obtained: CFI= 0.937, PCFI =0.711, and RMSEA=0.067. They showed that the model had goodness-of fit. The findings of the structural equation model in research showed self-directed learning and learning styles affected directly and indirectly on the educational achievement but learning strategy effected directly on educational achievement. Learning strategies have the most influence on the educational achievement.
