Secondary Science Leadership, Ready for U.S. Classrooms
By Praxical Strategies
Three secondary science educators — a curriculum architect, an equity-minded practitioner, and an inclusive innovator — bring decades of inquiry-based teaching and departmental leadership to U.S. classrooms. Explore their profiles.
Behind every thriving secondary science program is an educator who treats the subject not as a set of facts to memorize, but as a way of thinking to practice. This week, Teacher Connect turns its lens to three secondary science educators whose careers have been defined by inquiry-based learning, mentorship, and departmental leadership — Rosalinda M. Ramos, Rene Madelo, and Roja Guia A. Gumban.
Three Educators, One Teaching Discipline
All three teach Science at the secondary level, spanning grades 7 through 10, and each brings a distinct emphasis within the discipline — from curriculum development and teacher mentoring to inclusive classroom design and technology integration. What unites them is a conviction that science becomes real for students when it connects to their lives.
Rosalinda M. Ramos: The Curriculum Architect
With more than three decades in science education, Rosalinda M. Ramos has built her practice around inquiry-based learning, standards-aligned instruction, and collaborative professional leadership. She integrates differentiated instruction, formative assessments, and real-world applications to deepen scientific understanding, and her experience mentoring colleagues and leading curriculum development positions her as a steadying presence for any science department.

Rene Madelo: The Equity-Minded Practitioner
Rene Madelo's 30-year career spans Biology, Chemistry, and Integrated Science for diverse student populations. His classrooms are known for a philosophy of equity and cultural responsiveness — students master rigorous standards while seeing science as relevant to their own lives. He has led departments, mentored fellow teachers, and pairs deep subject knowledge with practical strengths in assessment design and laboratory safety.
Roja Guia A. Gumban: The Inclusive Innovator
Roja Guia A. Gumban brings nearly two decades of science and biology teaching across high school, middle school, and higher education in both the Philippines and the United States. A former Science Department Head and practicum supervisor, she designs standards-aligned, data-driven instruction for diverse learners — including gifted and multilingual students — and enriches it with STEM integration, gamified learning tools, and hands-on discovery.
