许多科学、技术、工程和数学学位要求通过物理入门课程。物理课程经常有很高的不及格率，这对那些历史上一直被种族主义、性别歧视和阶级歧视边缘化的学生造成了不成比例的伤害。我们研究了学习助理（LA）支持的课程与物理导论课程中不及格分数（即降、不及格或退学）的公平性之间的关系。研究中使用的数据来自于一个拉美裔地区服务机构41个物理导论课程的2312名学生。我们开发了考虑性别、种族、第一代身份和洛杉矶支持教学的学生DFW率的分层广义线性模型。我们使用了定量批判种族理论（QuantCrit）的视角，专注于霸权权力结构在使不公平的学生成绩永久化中的作用。我们的QuantCrit视角为我们的研究问题、方法和对研究结果的解释提供了信息。这些模型将LAs与DFW率的总体下降联系起来，并且黑人、土著和有色人种的DFW率比白人同龄人下降得更大。虽然在洛杉矶大学支持的课程中，DFW比率的不平等程度较低，但这种不平等仍然存在。
Many science, technology, engineering, and math degrees require passing an ntroductory physics course. Physics courses often have high failure rates that disproportionately harm students who are historically and continually marginalized by racism, sexism, and classism. We examined the associations between learning assistant (LA) supported courses and equity in nonpassing grades [i.e., drop, fail, or withdrawal (DFW)] in introductory physics courses. The data used in the study came from 2312 students in 41 sections of introductory physics courses at a regional Hispanic serving institution. We developed hierarchical generalized linear models of student DFW rates that accounted for gender, race, first-generation status, and LA-supported instruction. We used a quantitative critical race theory (QuantCrit) perspective focused on the role of hegemonic power structures in perpetuating inequitable student outcomes. Our QuantCrit perspective informed our research questions, methods, and interpretations of findings. The models associated LAs with overall decreases in DFW rates and larger decreases in DFW rates for Black, Indigenous, and people of color than their White peers. While the inequities in DFW rates were lower in LA-supported courses, they were still present.
