The paper explores the implementation of flexible teaching and learning modalities in mathematics education in response to the COVID-19 pandemic. It focuses on assessing the modalities used by Mathematics Teacher Educators (MTEs), learners’ perceptions of flexible teaching and learning, opportunities for improvement, and developing an action plan to enhance these modalities. The teaching research study emphasizes the implementation of flexible instructional approaches. The research involves a mixed-methods research design to gather data and analyze results in a state university in West (...) Philippines. The possible audience for this paper includes mathematics educators, MTEs, educational researchers, curriculum developers, and policymakers interested in enhancing teaching and learning modalities in mathematics education, especially in response to challenges like the COVID-19 pandemic.
