Recent research suggests that learning about genetics during high school biology can lead to a belief that inherent differences in the genes and brains of men and women are the main causes of gender differences in behavior and intellectual abilities (a belief known as neurogenetic essentialism). This belief is implicated in lowering girls’ sense of their own STEM abilities, their feelings of belonging in STEM classes, and their interest in pursuing further education in STEM fields. The goal of this project, led by a team of researchers at Biological Sciences Curriculum Study, the University of Texas, Austin, and New York University is to answer important questions about how to teach genetics at the high school level in a manner that is scientifically accurate, but does not have these detrimental side effects. Specifically, this new line of experimental research will identify—and revise—the content in common genetics instruction that promotes the belief in neurogenetic essentialism. The proposed experiments will also explore how the beliefs of peers and teachers contribute to changes in such beliefs in students. This work has further implications for how the topic of differences between men and women is addressed during high school biology education. Furthermore, the research findings will advance theory on factors that contribute to gender disparities in STEM attitudes and aspirations. The project is funded by the EHR Core Research (ECR) program, which supports work that advances the fundamental research literature on STEM learning, with co-funding by the Discovery Research PreK-12 (DRK12) program. Building on preliminary evidence, this project aims to accomplish four key goals. First, the project will study which specific aspects of genetics instruction affect students’ beliefs in neurogenetic essentialism. Second, the project will identify the cognitive mechanisms through which these effects occur. Third, the project will uncover the downstream effects of revised genetics instructional materials on a broad range of motivational variables relevant to STEM pursuit, such as implicit person theories, sense of belonging in STEM, and interest in this domain. Fourth, the project will explore the contextual factors (e.g., teacher and peer beliefs) that may moderate or mediate how students respond to the instructional materials. The research team will develop and iteratively refine genetics educational materialsthat teach about genetic, neurological, and behavioral variation within and between sexes, as well as the social causes of such differences. The research team will then test the effectiveness of these revised materials through two large-scale randomized control trials, one targeting students directly and one targeting students’ learning via their teachers. The results of this project will produce generalizable knowledge regarding the cognitive, sociological, and educational factors that contribute to STEM gender disparities.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

最近的研究表明，在高中生物学中学习遗传学可能会导致一种信念，即男性和女性在基因和大脑方面的固有差异是导致行为和智力性别差异的主要原因(这种信念被称为神经遗传学本质论)。这种观念降低了女孩对自己STEM能力的认同感，降低了她们在STEM课堂上的归属感，降低了她们在STEM领域深造的兴趣。这个项目由德克萨斯大学奥斯汀分校和纽约大学生物科学课程研究的一组研究人员领导，目的是回答一些重要的问题，即如何在高中水平上以科学准确的方式教授遗传学，但不会产生这些有害的副作用。具体地说，这一新的实验研究路线将确定-并修改-普通遗传学教学中促进神经发生本质论信念的内容。拟议中的实验还将探索同龄人和教师的信念如何有助于学生这种信念的改变。这项工作对如何在高中生物教育中解决男女之间的差异这一话题具有进一步的影响。此外，研究结果将推动关于导致STEM态度和愿望中的性别差异的因素的理论。该项目由EHR核心研究(ECR)计划资助，该计划支持推进STEM学习基础研究文献的工作，并由探索研究PreK-12(DRK12)计划共同资助。在初步证据的基础上，该项目旨在实现四个关键目标。首先，该项目将研究遗传学教学的哪些具体方面影响学生对神经发生本质论的信念。其次，该项目将确定这些影响发生的认知机制。第三，该项目将揭示修订后的遗传学教材对与STEM追求相关的广泛动机变量的下游影响，例如内隐个人理论、对STEM的归属感以及对该领域的兴趣。第四，该项目将探索背景因素(例如，教师和同伴信念)，这些因素可能会调节或调解学生对教学材料的反应。研究小组将开发并反复改进遗传学教材，教授性别内部和性别之间的遗传、神经和行为差异，以及这些差异的社会原因。研究小组随后将通过两项大规模随机对照试验来测试这些修订材料的有效性，一项直接针对学生，另一项针对学生通过教师学习。该项目的结果将产生关于导致STEM性别差异的认知、社会学和教育因素的概括性知识。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
