As the COVID-19 pandemic took hold in early months of 2020, education at all levels was pushed to emergency fully remote, online formats. This emergency shift affected all aspects of teaching and learning with very little notice and often with limited resources. Educators were required to convert entire courses online and shift to remote instructional approaches practically overnight. Students found themselves enrolled in online courses without choice and struggling to adjust to their new learning environments. This article highlights some of the challenges and successes of teaching emergency online undergraduate statistics courses. In particular, we discuss challenges and successes related to (1) technology, (2) classroom community and feedback, and (3) student-content engagement. We also reflect on the opportunity to continue to enhance and enrich the learning experiences of our students by utilizing some of the lessons learned from emergency online teaching as new permanent online statistics courses are developed and/or moved back into the classroom.
随着新冠肺炎疫情在2020年初爆发,各级教育都被推到了紧急状态下的完全远程在线形式。这种紧急转变影响了教学的各个方面,很少引起注意,而且资源往往有限。教育工作者被要求将整个课程转换为在线课程,并几乎在一夜之间转向远程教学方法。学生们发现自己在没有选择的情况下参加了在线课程,并且很难适应新的学习环境。这篇文章强调了在本科统计学应急在线课程教学中的一些挑战和成功。特别是,我们讨论了与(1)技术、(2)课堂社区和反馈以及(3)学生内容参与相关的挑战和成功。随着新的永久在线统计课程的开发和/或搬回课堂,我们还反思有机会通过利用从紧急在线教学中吸取的一些教训,继续增强和丰富学生的学习体验。

Abstract Statistical competitions like ASA DataFest and the Women in Data Science (WiDS) Datathon give students valuable experience working with real, challenging data. By participating, students practice important statistics and data science skills including data wrangling, visualization, modeling, communication, and teamwork. However, while advanced students may have already acquired these skills over the course of their undergraduate program, students with less experience often need additional preparation to participate. In this article, we discuss strategies and targeted activities for helping lower-level students feel comfortable and prepared to compete in events like DataFest. We also share how we used these tools to create a low-stakes DataFest preparation course at our institution. Supplementary materials for this article are available online.

Abstract We present a unique and innovative course, Biostatistical Literacy, developed at the University of Minnesota. The course is aimed at public health graduate students and health sciences professionals. Its goal is to develop students’ ability to read and interpret statistical results in the medical and public health literature. The content spans the typical first-semester introductory material, including data summaries, hypothesis tests and interval estimation, and simple linear regression, as well as material typically presented in a second introductory course, including multiple linear regression, logistic regression, and time-to-event methods. The focus is on when to use a method and how to interpret the results; no statistical software computing is taught. A flipped classroom approach is used, where students are first exposed to the material outside of class, and class time is devoted to actively exploring and applying the concepts in greater depth. The course structure, the class activities, and feedback from students will be shared. Supplementary materials for this article are available online.

Abstract Learners’ efficacy beliefs are an important determinant of their performance and future study in an academic domain, and recent work has highlighted the complexities associated with promoting learners’ statistics efficacy. The current study tested the effectiveness of a course-embedded, activity-driven intervention, grounded in principles of self-regulated learning, in promoting graduate learners’ statistics efficacy and concept knowledge. The intervention was designed to elicit and scaffold students’ analysis-specific efficacy beliefs and facilitate their monitoring of and critical reflection on their statistics understanding across engagement in an intermediate, graduate-level statistics course. Students’ pre- and post-course statistics efficacy was assessed; students’ statistics concept knowledge was assessed at the completion of the course. Engagement in the intervention explained a moderate amount of variance in learners’ post-course statistics efficacy and concept knowledge; efficacy and concept knowledge scores were higher for students in the intervention condition compared with students in the comparison condition. The findings suggest the use of these activities as a method of prompting students to engage more strategically with learning material in statistics. Implications for future research and pedagogy are discussed.
在学术领域,学习者的效能信念是其学习表现和未来学习的重要决定因素,最近的研究突出了提高学习者统计效能的复杂性。本研究检验了基于自我调节学习原则的课程嵌入、活动驱动的干预在促进研究生学习者统计效能和概念知识方面的有效性。干预的目的是诱导和支撑学生的分析特定功效信念,并促进他们在参与中级研究生水平的统计学课程时对统计理解的监测和批判性反思。对学生课前、课后统计效果进行评估;在课程结束时评估学生的统计学概念知识。参与干预解释了学习者课后统计效能和概念知识的适度差异;干预组学生的效能和概念知识得分高于对照组学生。研究结果建议使用这些活动作为一种方法,促使学生更有策略地参与统计学习材料。讨论了对未来研究和教学的启示。

Abstract This study explores three understudied facets—quadratic effects, change over time, and gender as a moderator—of the otherwise well-documented relationships between statistics anxiety and academic performance. Using pre- and post- course survey data among a sample of 111 undergraduate students in Social Statistics courses at a U.S. Midwestern university, we employ hierarchical linear modeling (HLM) to test for relationships between change in the six dimensions of the Statistics Anxiety Rating Scale (STARS) and exam grades over the course of the semester. We find that exam grades decreased over time, but at different rates across gender and the six STARS dimensions. We also identify a quadratic relationship between self-concept and final exam grades, as well as several gender interactions. This study highlights the multifaceted and dynamic nature of statistics anxiety/attitudes, as its relationship with academic performance is not always negative, linear, stable over time, or uniform across gender. Supplementary materials for this article are available online.
摘要本研究探讨了统计焦虑与学习成绩之间的三个未充分研究的方面——二次效应、随时间的变化和性别作为调节因素——否则,统计焦虑与学业成绩之间的关系就会得到充分的证明。使用美国中西部大学社会统计学课程的111名本科生的课前和课后调查数据,我们采用分层线性模型(HLM)来测试统计焦虑评定量表(STARS)六个维度的变化与本学期考试成绩之间的关系。我们发现,考试成绩随着时间的推移而下降,但在性别和六个STARS维度上的下降率不同。我们还发现了自我概念和期末考试成绩之间的二次关系,以及几种性别互动。这项研究强调了统计焦虑/态度的多方面和动态性质,因为它与学习成绩的关系并不总是负面的、线性的、随时间稳定的,也不总是性别一致的。本文的补充材料可在线获取。

Abstract Interactive web-based applets have proven effective in teaching statistics. This article presents new implementations of web-based applets primarily targeting a traditional introductory statistics course in two particular areas: (a) using real-time response data to engage students in simulations and (b) generating randomized datasets for assignments. It also provides an extended use case in courses beyond the traditional introductory statistics course. All applets given in the examples are made using the open-source package Shiny in R. The source code with detailed comments for all applets in this article is available in the supplementary materials section for other instructors to adopt and tailor to their needs. Supplementary materials for this article are available online.

Abstract We provide tools for identification and exploration of data with very large variability having power law tails. Such data describe extreme features of processes such as fire losses, flood, drought, financial gain/loss, hurricanes, population of cities, among others. Prediction and quantification of extreme events are at the forefront of the current research needs, as these events have the strongest impact on our lives, safety, economics, and the environment. We concentrate on the intuitive, rather than rigorous mathematical treatment of models with heavy tails. Our goal is to introduce instructors to these important models and provide some tools for their identification and exploration. The methods we provide may be incorporated into courses such as probability, mathematical statistics, statistical modeling or regression methods. Our examples come from ecology and census fields. Supplementary materials for this article are available online.

Abstract Data Analytics has grown dramatically in importance and in the level of business deployments in recent years. It is used across most functional areas and applications, some of the latter including market campaigns, detecting fraud, determining credit, identifying assembly line defects, health services and many others. Indeed, the realm of analytics has famously grown to include major league sports and even U.S. election campaigns. Universities have raced to include data analytics in their curricula as the need for data scientists has become more acute. Unfortunately, many data science courses in college curricula suffer from various deficiencies: some lack a hands-on component, others are insufficiently experiential, and yet others leave students with too few transferable skills. This article describes an experiential approach to teaching data analytics at the college level that uses an election simulation, MISSimulation.com—to communicate key data science concepts in a competitive setting. Many universities actively use the simulation, combined with analytic tools such as Tableau and Excel, to implement team competition. We explore key techniques used and knowledge learned during the typical teaching of a data analytics course using the simulation. We end with pedagogical review of data analytics skills transferred during the course and student feedback.
