Title: Spaced Retrieval Practice Imposes Desirable Difficulty in Calculus Learning
Abstract After being taught how to perform a new mathematical operation, students are often given several practice problems in a single set, such as a homework assignment or quiz (i.e., massed practice). An alternative approach is to distribute problems across multiple homeworks or quizzes, increasing the temporal interval between practice (i.e., spaced practice). Spaced practice has been shown to increase the long-term retention of various types of mathematics knowledge. Less clear is whether spacingdecreasesperformance during practice, with some studies indicating that it does and others indicating it does not. To increase clarity, we tested whether spacing produces long-term retention gains, but short-term practice costs, in a calculus course. On practice quizzes, students worked problems on various learning objectives in either massed fashion (3 problems on a single quiz) or spaced fashion (3 problems across 3 quizzes). Spacing increased retention of learning objectives on an end-of-semester test but reduced performance on the practice quizzes. The reduction in practice performance was nuanced: Spacing reduced performance only on the first two quiz questions, leaving performance on the third question unaffected. We interpret these findings as evidence that spacing led to more protracted, but ultimately more robust, learning. We, therefore, conclude that spacing imposes a desirable form of difficulty in calculus learning.  more » « less

    This study examined the difficulty introduced by spaced retrieval practice in Calculus I for undergraduate engineering students. Spaced retrieval practice is an instructional technique in which students engage in multiple recall exercises on the same topic with intermittent temporal delays in between. Spacing out retrieval practice increases the difficulty of the exercises, reducing student performance on them. However, empirical research indicates that spaced retrieval practice is associated with improvements in students’ long-term memory for the retrieved information. The short-term costs and long-term benefits of spaced retrieval practice is an example of desirable difficulty, when more difficult exercises during the early stages of learning result in longer-lasting memory [1]. With support from the National Science Foundation (NSF), we sought to address: Does spacing decrease performance on retrieval practice exercises in an engineering mathematics course? Results showed that student performance was significantly lower for questions in the spaced condition than questions in the massed condition, indicating that we successfully increased the difficulty of the questions by spacing them out over time. Future work will assess final quiz performance to determine whether spacing improved long-term course performance, i.e., whether the difficulty imposed by spacing was desirable.

    This WIP Research Paper investigates the temporal nature of the difficulty imposed by spacing. Spaced retrieval practice is an evidence-based strategy for improving memory and consists of asking multiple questions on a topic with intermittent delays. Spacing is often thought to impose difficulty by making questions harder to answer. However, this difficulty may be desirable, since spacing ultimately improves memory. In this paper, we (a) outline an implementation of spaced retrieval practice in an engineering mathematics classroom, (b) describe the development of an SQL database to organize and manage the large and complex dataset, and (c) discuss a brief but interesting dive into the rich data we have collected. Statistical analyses revealed that, when three questions targeting the same topic are spaced over multiple quizzes, versus being massed on a single quiz, students are less likely to answer the first and second questions correctly. Spacing does not affect students' ability to answer the third questions. This suggests that spacing may impose difficulty when students are first learning to perform mathematical operations, rather than when they are trying to retrieve memories of how to perform those operations.

    The focus of our current National Science Foundation (NSF: IUSE Award #1912253) project is the degree to which spaced retrieval practice, as compared to massed, increases performance on an end-of-semester exam in 10 different STEM courses (e.g., engineering, chemistry, biology). This paper presents an intermediate analysis examining the psychometric properties of the retrieval-practice exercises in two specific courses. The critical question is whether the psychometric properties of the exercises differ depending on whether they are spaced or massed. Preliminary results indicate that spacing does not consistently affect reliability of items, but can impact item difficulty.

    Given the demonstrated prevalence of a “doer effect” showing that active practice is related to substantially larger learning gains than passive approaches, an important research goal is to investigate whether and how different active practice features promote students’ learning outcomes. We investigated these questions in the context of an online learning platform that teaches e-learning design principles. In particular, we considered two different practice modes -practice activities inserted in the text (inline practice) and review practice quizzes -and compared their contributions to students' learning outcomes, in terms of module quizzes, periodic exams, and course projects. Our results showed that the different practice modes had distinct impacts on learning outcomes. Doing inline practice activities contributed to students’ quiz performance at the first attempt and project performance while doing review practice quizzes helped students improve their periodic exam performance. We offer some instructional suggestions such as emphasizing practice activities that are more clearly linked with specific learning objectives for projects, and emphasizing review practice quizzes for exam preparation.

    Abstract In this study, we examined students’ natural studying behaviors in massive, open, online course (MOOC) on introductory psychology. We found that, overall, distributing study across multiple sessions—increasing spacing—was related to increased performance on end-of-unit quizzes, even when comparing the same student across different time-points in the course. Moreover, we found important variation on who is more likely to engage in spaced study and benefit from it. Students with higher ability and students who were more likely to complete course activities were more likely to space their study. Spacing benefits, however, were largest for the lower-ability students and for those students who were less likely to complete activities. These results suggest that spaced study might work as a buffer, improving performance for low ability students and those who do not engage in active practices. This study highlights the positive impact of spacing in real-world learning situations, but more importantly, the role of self-regulated learning decisions in shaping the impact of spaced practice.
