Retention through Remediation : Enhancing Calculus I Success

“通过补救保留：提高微积分I的成功”是一个类型1-B的步骤项目。该项目在之前的Step 1-A奖项成功的基础上，正朝着改善学生数学背景的新方向努力，以此作为留住STEM专业的手段。这个桥接式项目使用了一系列以技术为基础的策略，以发现STEM新生的微积分预科/代数技能较差，并为他们提供个性化学习计划，以加强他们的微积分预科技能，为他们在大学数学中取得成功奠定基础。该方法首先使用微积分准备评估工具的结果，该工具是在他们的第一步-A项目中开发的，以确定哪些入学学生在数学上处于风险之中。然后，他们通过各种技术调解方法与这些学生进行跟进，包括通过会议软件与经验丰富的教师直接同步联系；重要的微积分预科主题的视频；用于增加互动性、理解深度和改善概念可视化的小程序；以及通过在线课程管理系统交付的在线文本、评估和家庭作业。这个项目是在他们大学第一学期之前的暑假进行的。在接下来的秋季学期，这些学生参加了“即时”课程，该课程强化了代数概念，因为它们是微积分I课程所需要的。这个项目的更广泛的影响包括他们开发了一个有效的、成本效益高的微积分预科课程的补救计划，供需要的大量学生使用，然后再学习微积分I，这是一门STEM入门课程。他们的评估设计正在提供基于技术的新知识，在进入大学前的那个夏天和第一次秋季体验中对代数能力较差的学生进行补救。这个项目团队正在传播他们的战略和一套软件工具，以成功地解决由于一年级微积分失败而导致的人员流失问题，这是一个普遍存在的问题，影响着全国各地院校的STEM毕业率。该项目在夏季和秋季干预措施中至少影响了3100名即将入学的STEM学生中的600人。他们的STEM毕业率每年至少增加100名STEM毕业生。该项目的外部咨询委员会正在就项目材料如何在其他校园内发挥作用提供专门知识，这有助于传播项目学习资源。正在编制演示文稿和出版物，以分享该项目的成功。

"Retention through Remediation: Enhancing Calculus I Success" is a Type 1-B STEP project. Building on the success of a previous STEP 1-A award, this project is working in the new direction of improving students' mathematical background as a means of retaining STEM majors. This bridge-type program is using a series of technology-based strategies for identifying new STEM students with weak pre-calculus/algebraic skills and providing them with a Personalized Study Program to strengthen their pre-calculus skills and position them for success in college mathematics. The approach begins with using the results from a Calculus Readiness Assessment tool, which was developed during their STEP 1-A project, to determine which incoming students are mathematically at risk. Then they follow-up with these students by a variety of technology-mediation methods including direct synchronous contact with an experienced instructor via conferencing software; videos of important pre-calculus topics; Applets to add interactivity, depth of understanding, and improve visualization of the concepts; and an online text, assessment, and homework delivered through an online course management system. This program is taken during the summer prior to their first semester of college. In the following fall semester, these students participate in the "Just-in-Time" program, which reinforces algebraic concepts, as they are needed in the Calculus I course. The broader impact of this project includes their development of an effective, cost-efficient remediation program in pre-calculus available to large numbers of students who need it, prior to taking Calculus I, which is a STEM-gateway course. Their evaluation design is providing new knowledge about technology-based remediation of algebraically weak students during that summer prior to entering college and again in the first fall experience. This project team is disseminating their strategy and set of software tools for successfully addressing the issue of attrition due to failure in first-year calculus, which is a widespread issue that impacts STEM graduation rates in institutions across the country.This project is impacting at least 600 of the incoming 3,100 STEM students in both the summer and fall interventions. They are increasing their STEM graduation rates by at least 100 additional STEM graduates annually. The project's External Advisory Board is providing expertise on how the project materials work within the context of other campuses, which is helping with the dissemination of project learning resources. Presentations and publications are being developed to share this project's successes.
