Abstract
Inquiry-Based Teaching Practice (IBTP) is an essential component of science education, and promoting its implementation is at the heart of various reform efforts. Even though science teachers regard IBTP as an essential pedagogical method, they rarely use it for various reasons. This study utilizes Bronfenbrenner's ecological framework to examine potential factors at various levels of the educational ecosystem that predict the implementation of inquiry-based teaching practices among Grade 9 science teachers in South Africa. To this end, quantitative data from 537 educators who participated in the Trends in International Mathematics and Science Study (TIMSS) 2019 national assessment were utilized. Data were analyzed using descriptive statistics, Pearson correlation, and hierarchical multiple regression analysis. Results revealed that four variables at different socioeconomic levels were perceived to strongly predict teachers' implementation of inquiry teaching practices. These factors include teachers' job satisfaction, instructional resource shortage, and teachers' perception of the significance of various assessment strategies at the mesosystem level as well as teachers' participation in professional development at the exosystem level. Significant correlations exist between some of the predictive variables. Implications for policy are discussed.
