How Inquiry-Based Immunology Transforms Students Into Researchers
In university laboratories around the world, a quiet revolution is transforming how students learn immunology. Gone are the days of simply following predetermined "recipes" to achieve expected results. In their place, a powerful educational approach called inquiry-based learning is challenging students to think, work, and write like genuine scientific researchers.
But what happens when students engage in authentic scientific inquiry? Recent research has delved into the epistemic practices—the ways students generate, justify, and communicate knowledge—that emerge when student groups tackle immunology problems. The findings reveal that through carefully designed inquiry activities, students don't just learn about immunology; they begin to think and reason like immunologists, developing crucial scientific literacy skills that extend far beyond the classroom 1 2 .
Before examining the immunology classroom, we must first understand 'epistemic practices.' The term refers to the specific ways scientists construct, justify, and communicate knowledge within their field. These aren't just procedures; they're the fundamental thinking tools of science.
Students learn to build arguments supported by experimental evidence rather than simply accepting established facts.
Students develop skills to interpret multifaceted data sets and draw meaningful conclusions from them.
Students learn to bridge the gap between experimental observations and theoretical frameworks.
Students practice articulating their thought processes and justifying their scientific conclusions.
Research analyzing student reports found that groups employ a rich variety of epistemic practices when writing about their immunology investigations, including predicting outcomes, drawing conclusions, describing phenomena, explaining mechanisms, and using theoretical knowledge to evaluate observed data 2 . These practices mark a significant shift from simply replicating experiments to genuinely creating scientific understanding.
Inquiry-based learning (IBL) creates the perfect environment for developing epistemic practices. Unlike traditional "cookbook" labs where students follow prescribed steps to reach a known answer, IBL places students in the driver's seat of their learning journey.
Students investigate a question provided by the instructor using prescribed methods. This approach provides scaffolding for students new to scientific inquiry.
Students design their own procedures to investigate a question provided by the instructor. This develops experimental design skills while maintaining focus.
Students formulate their own research questions, design experiments, and conduct full investigations. This mirrors authentic scientific research most closely.
The goal across this continuum is what researchers call "genuine inquiry"—where students search for answers to problems and construct their own knowledge rather than seeking predetermined "right" answers 1 . This approach requires higher-level thinking but develops skills directly transferable to disciplinary research.
Let's examine how inquiry-based learning plays out in an actual immunology course. At one university, final-year students undertake a sophisticated investigation spanning four five-hour sessions focused on inflammation 1 3 .
Students receive two cornerstone immunology techniques—ELISA (Enzyme-Linked Immunosorbent Assay) and flow cytometry-based cytokine bead array—which they use to formulate their own study investigating inflammation 1 .
Student groups brainstorm ideas that might impact inflammation, researching everything from dietary interventions like green tea or turmeric to physical activities.
Students perform their chosen intervention, collect saliva samples at multiple time points, and analyze them using the provided techniques.
Students analyze data, apply appropriate statistics, and write comprehensive reports detailing their findings.
The open-ended nature of this investigation leads to fascinating student-generated research questions. Some groups have explored:
The anti-inflammatory effects of daily boiled peanut consumption over one week
The impact of tequila consumption on inflammatory markers (with careful ethical consideration of alcohol use)
The effect of vigorous exercise on cytokine profiles
One group investigating tequila even addressed confounding variables by having participants consume a predetermined healthy meal beforehand, demonstrating sophisticated experimental design thinking 1 .
When researchers analyzed reports from immunology inquiry activities, they discovered fascinating patterns in how students represent and use scientific knowledge 2 5 .
A 2019 study published in Biochemistry and Molecular Biology Education found that while students capably performed data collection through in vitro assays, their written reports revealed important insights about their engagement with scientific practices 2 .
These findings suggest that immunology education strategies should provide explicit approaches exploring the role of data representation in scientific rhetoric 2 .
| Practice Category | Specific Examples | Frequency in Analysis |
|---|---|---|
| Data-Focused | Predicting, concluding, describing observed results | Most common |
| Theory-Focused | Explaining mechanisms, using theoretical concepts | Less common |
| Evaluation | Assessing data consistency, considering alternatives | Varied |
| Communication | Creating appropriate representations, citing evidence | Developing |

The emergence of digital learning environments has created new opportunities for developing epistemic practices. Recent research demonstrates that these valuable scientific thinking skills can be cultivated even in hybrid and online settings 6 .
In one study, students used WhatsApp mobile application to negotiate the construction of reports containing graphs, discussions, and conclusions to immunology problems 6 . Researchers provided numerical experimental data related to immunology topics through virtual learning environments, and student groups collaborated digitally to analyze and interpret this information.
Remarkably, analysis of the resulting reports still showed clear evidence of epistemic practices in student discourse, demonstrating that the development of scientific thinking transcends traditional classroom boundaries 6 . This finding has particular relevance for science education in the context of increasing digital and remote learning options.
Students used WhatsApp to collaboratively analyze immunology data and construct scientific reports.
| Research Tool | Function in Investigation | Application in Student Experiments |
|---|---|---|
| Competitive ELISA | Detects and quantifies specific antigens | Measuring levels of leukotriene B4 (LTB4) in saliva samples |
| Cytokine Bead Array (CBA) | Simultaneously measures multiple cytokines | Analyzing profiles of IL-1β, IL-6, IL-8, IL-10, IL-12p70, and TNF in saliva |
| Saliva Sampling | Non-invasive biological sample collection | Tracking changes in inflammatory markers before and after interventions |
| Statistical Analysis Software | Determines significance of findings | Analyzing data, applying appropriate statistical tests to determine intervention effects |
The Enzyme-Linked Immunosorbent Assay (ELISA) is a plate-based assay technique designed for detecting and quantifying substances such as peptides, proteins, antibodies, and hormones.
Flow cytometry-based cytokine bead array allows simultaneous measurement of multiple cytokines in a single sample, providing a comprehensive view of immune responses.
The implementation of inquiry-based learning in immunology education represents more than just a novel teaching strategy—it addresses fundamental goals of higher education in the sciences.
Research indicates that the benefits of inquiry-based approaches may be particularly pronounced for students who enter university with lower grades, suggesting this approach helps level the educational playing field 1 .

Training instructors to effectively facilitate inquiry-based learning
As science education continues to evolve, the explicit teaching and assessment of epistemic practices offers promising pathways for developing not just knowledgeable students, but genuine scientific thinkers.
The analysis of epistemic practices in immunology students' reports reveals much more than what students are learning—it shows us how they're learning to think. By engaging in authentic inquiry, students transform from passive recipients of knowledge to active creators of understanding.
As educational researchers continue to refine inquiry-based approaches in immunology and beyond, the focus remains on developing activities that explicitly promote the epistemic practices that define scientific expertise. The future of science education lies not merely in teaching what we know, but in engaging students in the authentic practice of how we come to know.
