Mathematics teaching is viewed as an inquiry process and a powerful context and practice for professional development with the goal of providing greater access, challenge, and support for every learner. This paper stems from a larger research project that investigates the research productivity and processes of integrating research in the curriculum delivery of high school mathematics. This descriptive work through survey, interview and documentary analysis involved 211 high school mathematics teachers in the quantitative component and four purposively selected in the qualitative section. Findings show that mathematics teachers demonstrate suboptimal level of research productivity but have shown promising potential for growth. Research is employed in various layers but typically as a mean to revisit teaching practices, as a basis of a teaching strategy, as a source of another research, and as a motivation for a research-oriented mindset. Research is strongly linked to the mathematics teaching and learning process and thus, have policy implications on nurturing and sustaining mathematics teacher-researchers. It is recommended to develop professional development plans that enhances the productivity and incorporation of research in the teaching-learning process.
