Assessing Critical Thinking in Modern Genetics Education
Imagine a classroom where students can perfectly recite the steps of DNA replication yet struggle to explain why identical twins with the same genes might develop different genetic disorders. This gap between knowledge retention and analytical reasoning represents one of the most significant challenges in modern genetics education. Today, simply understanding genetic concepts is no longer sufficient—students must develop the higher-order thinking skills (HOTS) necessary to analyze complex genetic information, evaluate conflicting evidence, and apply knowledge to novel scenarios they'll encounter in both academic and real-world contexts 6 .
Emphasis on memorization of genetic concepts without developing analytical capabilities.
Focus on developing critical thinking skills to apply knowledge in novel scenarios.
The field of genetics has evolved dramatically from the simple Mendelian inheritance patterns many of us learned in school. With advancements like epigenetics revealing how environmental factors influence gene expression, and artificial intelligence accelerating genetic research, the need for critical thinking in genetics has never been more pressing 8 . This article explores how educators are developing innovative methods to assess these essential skills—methods that are not only valid, practical, and reliable but that truly prepare students for the complexities of modern genetic science.
Higher-order thinking skills transcend basic memorization and recall, encompassing the cognitive processes that enable students to analyze, evaluate, and create new understanding. In genetics education, these skills are particularly crucial because they mirror the actual thought processes used by genetic researchers and counselors.
Breaking down complex genetic concepts into constituent parts to understand relationships and organizational principles . For example, a student might analyze how multiple genes interact with environmental factors to influence disease risk rather than simply memorizing gene-disease associations.
Making judgments about genetic information based on criteria and standards . This skill enables students to critique scientific studies, assess the quality of genetic evidence, or evaluate ethical implications of genetic technologies.
Awareness and understanding of one's own thought processes . In genetics, this might involve students reflecting on how they approach genetic problems or monitoring their understanding of complex inheritance patterns.
The traditional approach to genetics education has often emphasized Mendelian genetics and the central dogma of molecular biology (DNA → RNA → protein), creating what some researchers describe as a "selective teaching tradition" 8 . While these fundamentals remain important, this approach can inadvertently promote genetic determinism—the oversimplified view that genes alone dictate outcomes 8 .
Understanding these complex interactions requires students to move beyond deterministic thinking and develop more nuanced analytical skills. As noted by Stetsenko (2017, 2018), this understanding has profound implications beyond science education—it potentially "dispel[s] biological determinism" and helps "disrupt inequality and counteract discrimination and marginalization" by challenging simplistic notions about genetic destiny 8 .
Traditional genetics assessments often focus on what students know rather than how they think. Modern approaches to evaluating higher-order thinking skills employ more sophisticated methods:
This approach integrates various data sources—including conversation data from collaborative discussions, decision-making behavior data, and environmental data from virtual simulation platforms—to assess thinking skills in authentic learning contexts 7 . Unlike traditional tests, these analytics provide real-time assessment of how students actually engage with genetic problems rather than just their final answers 7 .
Educators are beginning to use generative artificial intelligence to create dynamic assessment scenarios that adapt to student responses, providing deeper insights into their thought processes 3 . These tools can simulate complex genetic counseling scenarios or research dilemmas that require students to apply multiple thinking skills simultaneously.
For any assessment method to be effective in genetics education, it must meet three key criteria:
The assessment must actually measure higher-order thinking skills rather than other factors like prior knowledge or test-taking ability. This is achieved through careful design that requires students to demonstrate reasoning processes explicitly 7 .
The method must be feasible for classroom implementation. Technology-assisted assessments have significantly improved practicality by automating data collection and analysis that would be prohibitively time-consuming for teachers to conduct manually 7 .
The assessment must produce consistent results across different contexts and student populations. Research shows that establishing reliability requires multiple assessment points and diverse measurement approaches 7 .
A compelling 2025 study examined how generative AI (GAI) could foster higher-order thinking skills among pre-service teachers specializing in science disciplines 3 . The research involved 473 participants from three higher education institutions who underwent a four-week generative AI-supported instructional design training program 3 .
The study employed a moderated mediation model to analyze the relationships between different types of thinking. Participants were assessed before and after the training program using a higher-order thinking skills survey, and 50 participants from the experimental group also participated in semi-structured interviews to provide qualitative insights into their experiences with AI-assisted teaching 3 .
The findings demonstrated that training pre-service teachers using generative AI to foster creative thinking significantly elevated their critical thinking abilities, which in turn enhanced their problem-solving capabilities 3 . Perhaps most importantly, the research identified that metacognitive thinking amplified the impact of creative thinking on critical thinking, resulting in a moderated mediation effect 3 .
The qualitative data from interviews provided crucial context for these statistical improvements. Participants reported that the AI-supported environment allowed them to "engage in effective thinking, employ appropriate reasoning, conduct independent evaluations, and effectively address real-life problems" in ways that traditional instruction had not facilitated 3 .
This study provides crucial evidence that generative AI, when properly integrated into educational frameworks, can significantly enhance the higher-order thinking skills necessary for modern genetics education 3 . The findings suggest that the relationship between different thinking skills is more interconnected than previously understood, with metacognition serving as a key amplifier in the development of critical analysis capabilities.
For genetics education specifically, these results indicate that AI-supported learning environments could help students develop the sophisticated reasoning skills needed to navigate the increasingly complex and data-rich field of modern genetics 6 . The demonstrated improvement in problem-solving abilities is particularly significant for preparing students to address real-world genetic challenges where textbook answers are often insufficient.

As genetic technologies continue to advance at an unprecedented pace, the ability to think critically about genetic information becomes increasingly vital—not just for future scientists but for all citizens navigating healthcare decisions, ethical dilemmas, and societal debates surrounding genetics. The development of valid, practical, and reliable methods for assessing higher-order thinking skills represents a crucial step toward preparing students for this complex landscape.
Ultimately, the goal is to create learning environments that challenge students to move beyond memorization and embrace the nuanced, critical, and creative thinking that modern genetics demands.
The future of genetics education lies not in teaching students what to think about the double helix, but in teaching them how to think about its countless unfolding complexities.
As research continues to refine our understanding of how these thinking skills develop and interact, educators are better positioned than ever to assess and foster the sophisticated reasoning abilities that will define the next generation of genetic scientists and informed citizens.
