My Teaching Philosophy

"To teach is to light a spark — to turn wonder into understanding, questions into exploration, and students into lifelong seekers of knowledge and purpose."

- Courage Mahuvava

Mastering a subject and teaching it effectively are two distinct skills. Teaching goes beyond simply transmitting knowledge; it requires fostering deep engagement, critical thinking, and a shared journey of discovery. As an ubdergraduate physics student, I occasionally encountered ineffective instruction—not due to a lack of expertise on the teacher’s part, but rather an inability to connect with and engage students. Material was often delivered in a monotonous, uninspiring, or confusing manner, to the point where, by the end of the semester, half the class had stopped attending lectures, while the other half had mastered the art of sleeping with their eyes open!

Now, nearly a decade later, I stand at the front of the classroom, committed to delivering interactive lectures — not magical sedatives.

At first glance, it may seem obvious — one group of students is actively participating, while the other is disengaged. But beneath the surface, this contrast reflects deeper dynamics of motivation, relevance, and connection to learning.

When students are empowered to see value in what they are learning — when lessons feel meaningful, interactive, and connected to their personal or professional aspirations — engagement becomes natural. Curiosity awakens, hands go up, and learning transforms from passive absorption to active exploration.

On the other hand, when material feels distant, overwhelming, or disconnected from real-world application, even the most talented learners may drift into disinterest. That is when you begin to see disengaged classrooms, blank stares, and a noticeable drop in curiosity and participation.

As educators, the challenge (and the opportunity) lies in bridging that gap: designing experiences where every student can find their reason to lean in, rather than tune out.

My Philosophy on Teaching

Fostering Curiosity and Connection in Complex Learning Environments

I primarily teach postgraduate courses in biomedical physics, including diagnostic imaging, dosimetry and radiotherapy physics, with some involvement in bioengineering and metrology in the undergraduate biomedical technology program. Given the inherent complexity of these courses, I had to learn the importance of engaging students through enthusiasm, humorous examples, and fun physics facts. This includes revealing the scientific mysteries of the physical world, and addressing not just the "how" but also the "why" behind them in a manner that invokes curiosity.

Empowering Independent Thinkers Through Constructivist, Student-Centered Learning

I adopt a student-centered approach grounded in constructivist principles, encouraging students to build their own understanding of concepts. Through Socratic inquiry and problem-solving, I promote deeper learning, critical thinking and self-reflection. I ask probing questions to understand what my students know, how they think, and why they choose certain approaches. Rather than providing "the answer" to a problem, I guide students toward discovering "an answer," encouraging them to develop their own problem-solving abilities. This approach empowers students to take ownership of their learning, to become independent thinkers, and to build confidence that extends beyond the classroom.

Fostering Interactive and Collaborative Learning Through Multimodal Teaching

I frequently use a whiteboard alongside slides to create a more interactive environment that encourages students to contribute to the discussion rather than passively receiving information. This collaborative learning approach, where we work through problems together, helps demystify complex ideas. Additionally, I incorporate multimedia resources such as videos and animations to illustrate difficult concepts, like the sliding filament theory of muscle contraction in my bioengineering classes. One of the most rewarding aspects of teaching is seeing my students progress from struggling with concepts to gaining confidence in their academic abilities.

Active learners “interact with their environment and manipulate the objects in that environment, observing the effects of their interventions and constructing their own interpretations of the phenomena and the results of the manipulation and sharing those interpretations with others” .

Bridging Theory and Practice Through Technology-Driven Experiential Learning & Simulation

In the field of medical physics, hands-on learning through clinical observation and residency training is essential. In an academic setting, however, time and resources may be limited, so I decided to create an experiential learning environment through technology. To achieve this, I had to revise the curriculum for one of the postgraduate Medical Physics labs to include simulations that allow students to virtually replicate treatment scenarios and observe the effect of changing different parameters on the treatment outcome. My ultimate goal is to develop well-rounded medical physicists who can seamlessly transition from classroom learning to real-world challenges.

Critical Pedagogy

I also embrace the idea that students should not only ask questions but critically challenge theories and assumptions. By fostering an environment where students feel empowered to question established ideas, they develop a greater sense of intellectual independence. This approach encourages diverse perspectives and cultivates a classroom culture of open dialogue and inquiry, where both students and teachers thrive together.

In March 2025, we visited and toured the TTBS with my BMET 3004 students to learn the practical application of metrology.

Situated Learning

Students have different learning styles, and some may not immediately recognize how classroom material relates to their future careers, particularly at the undergraduate level. My teaching philosophy centers on fostering an environment that encourages supervised exploration. Field trips have proven highly beneficial as a form of situated learning. For instance, every year, we take undergraduate Metrology students to calibration stations of the Trinidad & Tobago Bureau of Standards (TTBS). After the visit, students reflect on their experiences and insights through written reports, which deepens their understanding of the practical applications of their studies.

Teaching as a Dynamic, Reflective, and Learner-Centered Practice

Teaching is also about personal growth. I view teaching as a dynamic process of continuous refinement, where every class is an opportunity to evolve. By regularly assessing my methods and testing new strategies, I adapt to meet the diverse needs of my students. Student feedback, whether gathered informally during the course or through formal course evaluations at the end of the semester, is essential for maintaining a learner-centered approach. I also engage in self-reflection, to avoid stagnation and embrace growth. In addition, peer observation offers professional advice that I can incorporate into my teaching. I emphasize the use of formative assessments—such as reflections, peer evaluations, group projects and low-stakes quizzes—to provide real-time feedback, helping students identify areas for improvement while enabling me to adjust my teaching strategies.

I have actively sought out continuous professional development (CPD) opportunities throughout my career. I regularly attend conferences, participate in workshops and online courses, and engage with the latest medical physics research to ensure that my teaching remains current with advancements in techniques and equipment used in radiotherapy. This ongoing commitment allows me to incorporate the latest innovations directly into my teaching.

Bridging Theory and Practice Through Authentic Assessments for Career-Ready Competencies

In medical physics, assessments are designed around real clinical problems to ensure that students develop practical skills directly applicable to their future careers. For example, I have assigned case studies where students critically analyze radiotherapy treatment plans, evaluating their acceptability based on criteria such as adherence to clinical protocols and the accuracy of the delivered radiation dose. In other instances, students have been presented with CT images and tasked with identifying abnormalities or artifacts, followed by a discussion on potential methods to enhance image quality for more accurate clinical diagnosis.

Conclusion

Teaching is a core part of my job as an academic medical physicist, and I am committed to fostering an engaging and student-centered learning environment. Given the rapid technological advancements in the medical physics field, I believe my educational beliefs and practices will continue to evolve as I gain new experience and stay informed about the latest developments in pedagogy and educational research. This adaptability is essential to remain effective and responsive to the ever-changing and interdisciplinary landscape of medical physics. Ultimately, my goal is to cultivate well-rounded medical physicists who are not only knowledgeable but also capable of applying their understanding in practical contexts, ensuring they are prepared for successful careers. Through problem-based learning, I aim to encourage critical thinking and the development of transferable skills that can be utilized not just in medical physics but also in broader professional settings.
