Reflection Paper #1: Identification and Selection of Research Problem

INTRODUCTION (Context)

The module on the identification and selection of a research problem aims to help students develop research questions that address significant gaps in knowledge while aligning with societal needs. My research determines the in vivo neurotoxic effects of microplastic (MP) exposure on peripheral nerve conduction by measuring changes in nerve excitability and sensitivity using electrophysiological parameters such as threshold voltage, maximum compound action potential, and relative refractory period. This study integrates dose-response methodologies and uses PowerLab to assess low, medium, and high doses of MP exposure, potentially revealing its impact on neurological health.

This topic aligns with the Cebu Doctors' University (CDU) Institutional Research Agenda regarding One Health (Human, Animal, Environment, and Plant Health). As part of this module, the following program outcomes were achieved: engaging in research activities (PO4), utilizing a systematic approach (PO6), engaging in personal and professional development (PO7), and practicing social accountability (PO10).

BODY (Experience, Reflections, Action)

While reviewing previous studies, I observed significant gaps in the literature regarding the neurotoxic effects of MP exposure on peripheral nerves. The challenge was identifying a relevant research question that could fill these gaps while contributing to public health knowledge. My research activities involved a comprehensive review of existing studies, which focused mainly on other body systems, like the central nervous system, leaving the peripheral nervous system largely unexplored. This gap presented both a challenge and an opportunity for innovation.  I connected this experience to PO4 by actively participating in the research process, from formulating the question to designing the possible methodology. The need for a systematic approach (PO6) became evident when determining how to structure the study to effectively measure MP exposure's impact on nerve conduction. Additionally, this experience was crucial for my professional development (PO7) as identifying a novel research problem challenged me to think critically, and enhanced my sense of social accountability (PO10), as I realized the study’s potential societal impact.

I realized the importance of selecting research topics that not only address academic gaps but also have real-world significance (PO4). The ability to identify a relevant and impactful research problem has given me a deeper appreciation for the role of science in addressing societal issues. I learned that a systematic approach (PO6) is essential for ensuring thorough planning, brainstorming, and reviewing of existing studies, all of which are critical for producing a research problem. By navigating through the complexities of the literature review and research design, I have gained a stronger sense of self-discipline and time management, which are crucial for my personal and professional development (PO7). Additionally, I realized that my work goes beyond academic achievement. It has the potential to affect public health policies and contribute to a better understanding of how environmental factors can influence neurological health. This awareness has deepened my commitment to conducting research that serves the greater good (PO10).

I will apply what I have learned by continuing to refine my research problem as well as draft methodology. I plan to consult experts in neurophysiology and toxicology to refine the study and ensure that the data being sought after is reliable and impactful. I also plan to encourage interdisciplinary research collaboration by possibly reaching out to environmental groups. This would lead to a more holistic understanding of MP pollution and exposure effects that help shape future research efforts in this field. Moreover, I aim to raise awareness about the issue by publishing the study once it is finished, in order to disseminate its findings and contribute to both academic and public health knowledge.

CONCLUSION (Evaluation)

The module on identifying and selecting a research problem provided invaluable insights into the research process, reinforcing the importance of selecting topics that address critical gaps while offering societal benefits. By identifying the under-researched area of MP neurotoxicity on peripheral nerves, I was able to align my work with the CDU One Health agenda, recognizing the interconnectedness of human health and environmental sustainability. This experience also emphasized the importance of persistence and a systematic approach in research, as well as the value of interdisciplinary collaboration. Ultimately, this activity deepened my understanding of research’s role in solving real-world problems and reaffirmed my commitment to contribute to both academic knowledge and societal well-being.
