Abstract

The Programme for International Student Assessment (PISA) is a global survey conducted by the Organisation for Economic Co-operation and Development (OECD) to assess educational systems by evaluating the academic performance of 15-year-old school students in mathematics, science, and reading. In PISA 2022, 13,437 students from Australia participated in the test. While the PISA main questionnaire assesses the subject knowledge, the student background questionnaire solicits contextual information such as school climate, learner characteristics, and socioeconomic status. This study analyses how these contextual variables predict student achievement using the machine-learning models Ridge Linear Regression, K-Nearest Neighbours, Decision Trees, eXtreme Gradient Boosting, and Support Vector Machines, and it reports the evaluation matrices and the most accurate model in predicting student achievement. The analysis shows that contextual variables are associated with student achievement and account for 42% of the variance in achievement. In addition to evaluating multiple machine-learning regressors, Shapley Additive Explanation (SHAP) analysis is conducted to explain the model predictions and evaluate feature importance. Using SHAP analysis, this paper demonstrates how educators and school administrators may effectively interpret the machine-learning results and devise strategies for student success.
