Students' self-regulated learning has become an essential element of student's success in the education sector and therefore, needs the attention of policymakers and scholars alike. Thus, the current study investigates into the role of different learning styles such as just-in-time learning, case-based learning, inquiry learning, project-based learning and problem-based learning on students' self-regulated learning in the context of public sector universities in Indonesia. Questionnaires are used by researchers to gather the data from respondents. The purposive sampling technique is used to select the student respondents who are using math journaling. Researchers also execute the PLS-SEM for the purpose of analysis and tests the validity, reliability and relationships among variables. The results indicate that all learning styles such as just-in-time learning, case-based learning, inquiry learning, project-based learning and problem-based learning have a positive nexus with students' self-regulated learning in public sector universities in Indonesia. This study provides valuable insights to policymakers regarding formulating new policies about student self-regulated learning.
