Wise  \n1Department of Biology, Roanoke College, Salem, VA 24153  \n*[Corresponding author:](Corresponding author: wise@roanoke.edu)[ ](Corresponding author: wise@roanoke.edu)[wise@roanoke.edu](Corresponding author: wise@roanoke.edu)  \nAbstract: The Hardy-Weinberg principle (HWP) is a fundamental model upon which much of the discipline of population genetics is based. Despite its significance, students often leave introductory biology courses with only a shallow understanding of the use and implications ofthe HWP. I contend that this deficiency in student comprehension is too-often a consequence of teachers of introductory biology having an insufficient mastery of the HWP, as well as a lack of proficiency in quantitative analysis in general. The purpose of this Perspectives paper is to correct some common misconceptions about the HWP so that teachers of introductory biology will have more confidence that they are communicating this important principle correctly to their students. A companion Innovations paper provides a problem-set of six real-world Hardy-Weinberg scenarios, along with explicit instructions on quantitatively analyzing the scenarios.  \nKeywords: evolutionary mechanisms, Hardy-Weinberg equilibrium, introductory biology, population genetics  \nThe Centrality of the Hardy-Weinberg Principle in Evolutionary Biology  \nThe Hardy-Weinberg principle (HWP) often serves as the foundation for students to build an understanding of how evolution works in populations of organisms. Nevertheless, applying the HWP tends to be one of the more difficult and thus least favorite topics for introductory biology students, due in part to the abstract (probabilistic) nature ofthe HWP, students’ preconceptions that biology should not include mathematics, and students’ lack of appreciation of the variety of real-world biological scenarios to which the HWP can be applied (Mertens, 1992; Winterer, 2001; Brewer & Gardner, 2013; Smith & Baldwin, 2015) . It does not help that instructors of introductory biology are often not specialists in population biology and may be just as uncomfortable with the quantitative aspects of HW problems as their students are (Masel, 2012) . As a result, the teaching ofthe HWP tends to be superficial, and students often move on to higherlevel biology courses with no deeper knowledge of the HWP than remembering a partial list of assumptions and the formula “p2 + 2pq + q2 = 1.”Worse yet, biology departments may decide to remove the teaching of HW from introductory courses altogether (Masel, 2012) .  \nI contend that it is a disservice to students to give superficial treatment to the HWP in an introductory biology course for several reasons. First, this topic serves as an entrée into the increasingly important discipline of population genetics. Failure to do it justice may result in a missed opportunity to attract or retain students whose interest in biology tends more  \nto the macro-scale than the cellular and molecular perspectives that constitute much of the course matter in introductory biology. Second, the HW perspective provides students with an appreciation that evolution is a phenomenon that happens continuously and that can be studied in real time (Winterer, 2001) . Third, using the HWP to analyze real (or creatively contrived) data provides an excellent way for students to employ the scientific method, including using simple statistics to test hypotheses. Thus, analysis of evolutionary scenarios using the HWP provides teachers an opportunity to answer the pedagogical call to incorporate quantitative activities into lecture courses (NRC, 2003; AAAS, 2011; Hoskinson et al., 2013; AAAS, 2015; McLaughlin & Metz, 2016) . Fourth, solving problems where the HWP is applied in an authentic way (not just plugging values into a formula) requires students to use hig","cbCaibpti1QcSjCp","https://ap.wps.com/l/cbCaibpti1QcSjCp","pdf",176398,"English","# The Centrality of the Hardy-Weinberg Principle in Evolutionary Biology\n## The Hardy-Weinberg Equilibrium","[{\"question\":\"What problem does the paper identify with students’ understanding of the Hardy-Weinberg principle?\",\"answer\":\"Students often retain only a shallow, partial understanding of the HWP’s use and implications after introductory biology, rather than deeper comprehension.\"},{\"question\":\"Why does the paper argue misconceptions arise when teaching the HWP?\",\"answer\":\"It argues that misconceptions come from teachers having insufficient mastery of the HWP and from limited proficiency in quantitative analysis.\"},{\"question\":\"What does the companion Innovations paper provide?\",\"answer\":\"It provides a problem set of six real-world Hardy-Weinberg scenarios along with explicit instructions for quantitatively analyzing them.\"}]","On Hardy-Weinberg in Introductory Biology - Teaching this Fundamental Principle in an Authentic, Engaging, and Accurate Manner | PDF",1792079853,13]
