This project aims to serve the national interest by increasing access to STEM fields for undergraduate students who need additional support to succeed in introductory Calculus courses. Co-requisite instruction can help academically underprepared undergraduate students succeed academically and stay on track to their intended STEM degree. The potential impact of co-requisite courses is particularly relevant for linear course sequences like the Precalculus through Calculus course sequence. This project aims to test an integrated approach to increase success in Calculus 1 through co-requisite Precalculus instruction. The project will rapidly identify students who will likely benefit from precalculus corequisite instruction and provide them with this support. In doing so, the project will test a data-driven, quick-response strategy for helping students succeed in Calculus I and subsequent Calculus courses. If this approach is successful, it could provide Institutions of higher education with a practical and effective strategy to ensure that students have more equitable access to success in college-level mathematics courses. It is expected that this approach will be of particular benefit to undergraduates whose education has been severely impacted by the COVID-19 pandemic.This three-year Engaged Student Learning Level I project at University of Alaska Fairbanks aims to implement an experimental academic intervention that will measure Precalculus content knowledge acquisition, success in Calculus I, and persistence to Calculus II for roughly 500 Calculus I students. A key focus of the project will be the implementation and evaluation of an experimental 2-credit co-requisite Precalculus course over four semesters. Through an experimental design, student cohorts with access to the intervention will be compared to historical cohorts with similar measures of academic preparation. The comparison will provide a multifaceted evaluation of the effectiveness of co-requisite instruction in support of the Calculus sequence and provide a rigorous test of whether co-requisite Precalculus instruction in support of Calculus 1 contributes to increasing student success in Calculus 1. Materials developed from the experiment, including identification protocols, curriculum materials, and statistical methods and analyses, will be publicly shared through a public project webpage. This project is funded by the NSF IUSE: EHR Program, which supports research and development projects to improve the effectiveness of STEM education for all students. Through the Engaged Student Learning track, the program supports the creation, exploration, and implementation of promising practices and tools. 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.

该项目旨在通过增加本科生进入STEM领域的机会来服务于国家利益，这些本科生需要额外的支持才能成功地完成微积分入门课程。辅修课程可以帮助学业准备不足的本科生在学业上取得成功，并保持在他们想要的STEM学位的轨道上。辅助必修课的潜在影响尤其与线性课程序列有关，如微积分到微积分的课程序列。这个项目的目的是测试一种综合的方法，通过共同必修的微积分基础教学来提高微积分1的成功。该项目将迅速确定哪些学生可能受益于微积分预科必修课的教学，并为他们提供这种支持。在此过程中，该项目将测试一种数据驱动的快速反应策略，以帮助学生在微积分I和后续的微积分课程中取得成功。如果这种方法是成功的，它可以为高等教育机构提供一种切实有效的战略，以确保学生有更公平的机会在大学一级的数学课程中取得成功。预计这种方法将对那些教育受到新冠肺炎事件严重影响的本科生特别有益。这个在阿拉斯加大学费尔班克斯大学开展的为期三年的参与式学生学习I级项目旨在实施一项实验性的学术干预，旨在衡量约500名微积分I学生的微积分前内容知识获得、微积分I的成功程度以及对微积分II的坚持程度。该项目的一个主要重点将是在四个学期内实施和评估一门试验性的两个学分的联合必修微积分课程。通过一项实验设计，可以获得干预措施的学生队列将与具有类似学术准备措施的历史队列进行比较。这项比较将对辅助教学支持微积分序列的有效性进行多方面的评估，并对支持微积分1的辅助必修教学是否有助于提高学生在微积分1中的成功程度进行严格的测试。从实验中开发的材料，包括识别方案、课程材料、统计方法和分析，将通过公共项目网页公开分享。该项目由NSF IUSE：EHR计划资助，该计划支持研究和开发项目，以提高所有学生的STEM教育的有效性。通过参与式学生学习路径，该计划支持有前景的实践和工具的创建、探索和实施。 该奖项反映了国家科学基金会的法定使命，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。
