Reducing complex systems to focus on simpler elements (reductionist approach) is used in teaching within multiple disciplines. Reductionist approaches may impact both students’ understanding of complex phenomena and their broader belief systems. While our presentation will focus on our introductory genetics course, these issues are applicable across disciplines. Genetics education often oversimplifies genetic systems, focusing on basic Mendelian genetics and ignoring the complex, multifactorial nature of phenotypes (i.e., observable traits of an organism). This reductionist approach can prevent students from not only developing an authentic understanding of genetics, but can also contribute to ideas of genetic determinism and essentialism. Genetic determinism is the belief that an organism’s genotype largely or exclusively controls its phenotype; traits are therefore ‘fixed’ and environmental influences are minimal. This can lead to deterministic thinking and racial stereotyping, as well as impacting a student’s sense of belonging and potentially result in underperformance on tasks due to stereotype threat (Dar-Nimrod & Heine, 2011; Donovan et al. 2020; Hales, 2020). Therefore, genetics education can have far-reaching consequences in our institutions and society. To address these issues, we redesigned our introductory genetics course to emphasize the multifactorial nature of phenotypes (i.e., interplay of genetics and the environment) and variation within populations. Our goal is to provide students with a more authentic understanding of phenotypic variation, which will serve as a strong foundation for future courses, and also reduce deterministic thinking, and resultant essentialist beliefs. Students completed pre-/post-term surveys to assess changes in determinist thinking, as well as class activities to assess their learning progression. We will present our experiences and analysis of the new curriculum. Attending in person?
