With support from the NSF Improving Undergraduate STEM Education Program: Education and Human Resources (IUSE: EHR), this project aims to serve the national interest by improving learning in introductory STEM courses through spaced retrieval practice. Spaced retrieval practice requires students to periodically answer questions that require them to recall what they previously learned. It is a is a memory-enhancing, research-based instructional technique that has been shown to improve memory of concepts both within and between semesters. Spaced retrieval practice is especially important in barrier courses where a lack of success restricts students from further pursuing STEM degrees. This project will study the effectiveness of spaced retrieval practice in ten different introductory STEM courses. This intervention may be most beneficial to students who traditionally underperform in STEM, thus helping to broaden participation in STEM careers.Building on previous results of the effectiveness of spaced retrieval in a few courses, this project aims to implementing and measuring the effects of spaced retrieval in ten different undergraduate STEM courses at the University of Louisville. Through a series of workshops, project team leaders will work with faculty to design spaced retrieval exercises for their courses. The intervention will then be implemented for one semester using the same implementation strategy in all courses, reaching a total of over 1,600 students. Retention of classroom content following spaced retrieval practice will be compared, in within-subjects fashion, to retention following massed retrieval practice. The effect of the practice manipulation (the magnitude of the difference between performance following spacing versus massing) will be compared across different courses, permitting assessment of spacing's effectiveness across domains. For those courses in which spaced retrieval practice is shown to be effective, the project will investigate whether the magnitude of the spacing-related benefit differs. In addition, it may be possible to detect other classroom design and demographic moderators of the effect, depending upon sample sizes and variations in classrooms. Results could provide evidence to support implementation of spaced retrieval as a strategy to increase student success in STEM courses nationwide. Increasing student success in STEM courses will lead to more individuals successfully pursuing STEM careers. It will also pave the way for future research to explore the impacts of spaced retrieval practice in the context of different types of institutions of higher education, potentially leading to even broader adoption of the intervention. The NSF IUSE: EHR Program 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.

本项目由美国国家科学基金会改善本科STEM教育计划：教育与人力资源（IUSE: EHR）资助，旨在通过空间检索实践改善STEM入门课程的学习，为国家利益服务。间隔记忆练习要求学生定期回答要求他们回忆之前所学内容的问题。这是一种增强记忆的、以研究为基础的教学方法，已被证明可以在学期内和学期之间提高对概念的记忆。间隔检索练习在障碍课程中尤其重要，因为缺乏成功限制了学生进一步攻读STEM学位。本项目将研究间隔检索练习在10门不同的STEM入门课程中的有效性。这种干预可能对传统上在STEM中表现不佳的学生最有利，从而有助于扩大STEM职业的参与。基于之前在一些课程中间隔检索的有效性结果，本项目旨在在路易斯维尔大学的10个不同的本科STEM课程中实施和测量间隔检索的效果。通过一系列的研讨会，项目小组领导将与教师合作，为他们的课程设计间隔检索练习。该干预措施将在一个学期内实施，在所有课程中使用相同的实施策略，总共惠及1600多名学生。间隔检索练习后课堂内容的记忆将以学科内的方式与大规模检索练习后的记忆进行比较。练习操作的效果（间隔与集中后的表现差异的大小）将在不同的课程中进行比较，允许跨领域评估间隔的有效性。对于那些间隔检索练习被证明有效的课程，该项目将调查与间隔相关的益处的大小是否不同。此外，根据样本量和教室的变化，也有可能检测到其他教室设计和人口统计学调节因子的影响。结果可以为支持将间隔检索作为提高全国STEM课程学生成功的策略提供证据。提高学生在STEM课程上的成功将导致更多的人成功地从事STEM职业。这也将为未来的研究铺平道路，探索在不同类型的高等教育机构背景下空间检索练习的影响，有可能导致更广泛地采用干预措施。NSF IUSE: EHR计划支持研究和开发项目，以提高所有学生STEM教育的有效性。通过参与学生学习轨道，该计划支持有前途的实践和工具的创建，探索和实施。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
