Title: Confidence disparities: Pre-course coding confidence predicts greater statistics intentions and perceived achievement in a project-based introductory statistics course.
Self-efficacy is associated with a range of educational outcomes, including science and math degree attainment. Project-based statistics courses have the potential to increase students’ math self-efficacy because projects may represent a mastery experience, but students enter courses with preexisting math self-efficacy. This study explored associations between pre-course math confidence and coding confidence with post course statistical intentions and perceived achievement among students in a project-based statistics course at 28 private and public colleges and universities between fall 2018 and winter 2020 (n=801) using multilevel mixed-effects multivariate linear regression within multiply imputed data with a cross-validation approach (testing n=508 at 20 colleges/universities). We found that pre-course coding confidence was associated with, respectively, 9 points greater post-course statistical intentions and 10 points greater perceived achievement on a scale 0–100 (0.09, 95% confidence interval (0.02, 0.17), p=0.02; 0.10, 95% CI (0.01, 0.19), p=0.04), and that minoritized students have greater post-course statistical intentions than non-minoritized students. These results concur with past research showing the potential effectiveness of the project-based approach for increasing the interest of minoritized students in statistics. Pre-course interventions to increase coding confidence such as pre-college coding experiences may improve students’ post-course motivations and perceived achievement in a project-based course.

To evaluate the impact of a multidisciplinary, project-based course in introductory statistics, this exploratory study examined learning experiences, feelings of confidence, and interest in future experiences with data for undergraduate students in Ghana, West Africa. Students completed a one-semester, introductory statistics course utilizing the Passion-Driven Statistics curriculum. Results showed more than half of the students put more effort into the course and found the material more challenging compared to other courses, while nearly three-quarters reported interest in one or more follow-up courses. Importantly, students also reported increased confidence in a variety of applied statistical skills. These findings demonstrate the positive impact of a multidisciplinary, project-based curriculum on undergraduate students in Ghana, West Africa and demonstrate the potential for its global portability.

Course-based undergraduate research experiences (CUREs) have been shown to help students gain research skills. Few studies, however, have evaluated the impact of CUREs on long-term educational and employment outcomes. This article examines postgraduation outcomes for students enrolling in introductory statistics delivered as a CURE compared with those taking a traditional mathematics-based introductory statistics course. Participating in the CURE was found to be associated with a higher likelihood of holding a job in which a primary responsibility was working with data, greater confidence in working with data, and a higher likelihood of earning more than $100K annually. This study suggests that CUREs may not only impart technical skills but also boost students’ self-efficacy in applying statistical methods and analyzing data.
The Association of American Colleges and Universities identifies undergraduate research experiences as a high impact practice for increasing student success and retention in STEM majors. Most undergraduate research opportunities for community college engineering students involve partnerships with universities and typically take the form of paid summer experiences. Course-based Undergraduate Research Experiences (CUREs) offer an alternative model with potential for significant expansion of research opportunities for students. This approach weaves research into the courses students are already required to complete for their degrees. CUREs are an equitable approach for introducing students to research because they do not demand extracurricular financial and/or time commitments beyond what students must already commit to for their courses. This paper describes an adaptable model for implementing a CURE in an introductory engineering design and computing course that features applications of low-cost microcontrollers. Students work toward course learning outcomes focused on computer programming, engineering design processes, and effective teamwork in the context of multi-term research and development efforts to design, build, and test devices for other CUREs in science lab courses as well as for other applications at the college or with community partners. Students choose from a menu of projects each term, with a typical course offering involving four to six different projects running simultaneously. Each team identifies a focused design and development scope of work within the larger context of the project they are interested in. They give weekly progress reports and gather input from their customers. The work culminates in a prototype and final report to document their work for student teams who will carry it forward in future terms. We assessed the impact of the experience on students’ beliefs about science and engineering, STEM confidence, and career aspirations using a nationally normed survey for CUREs in STEM and report results from five terms of offering this course. We find statistically significant pre-post gains on two-thirds of the survey items relating to students’ understanding of the research process and confidence in their STEM abilities. The pre-post gains are generally comparable to those reported by others who used the same survey to assess the impact of a summer research experience for community college students. These findings indicate that the benefits of student participation in this CURE model are comparable to the benefits students see by participation in summer research programs.

Learning standards for biology courses have called for increasing statistics content. Little is known, however, about biology students’ attitudes towards statistics content and what students actually learn about statistics in these courses. This study aims to uncover changes in attitudes and content knowledge in statistics for students in biology courses. One hundred thirty-four introductory biology students across five different instructors participated in a pre-post study of statistical thinking and attitudes toward statistics. Students performed better on the statistics conceptual inventory at the end of a biology course compared to the beginning. Student attitudes showed no change. These preliminary results suggest the potential importance for laying a conceptual foundation in statistics prior to taking biology courses with little formal statistical instruction.

Online learning is increasing in both enrollment and importance within engineering education. Online courses also continue to confront comparatively higher course dropout levels than face-to-face courses. This research paper thus aims to better understand the factors that contribute to students’ choices to remain in or drop out of their online undergraduate engineering courses. Path analysis was used to examine the impact of course perceptions and individual characteristics on students’ course-level persistence intentions. Specifically, whether students' course perceptions influenced their persistence intentions directly or indirectly, through their expectancies of course success, was tested. Data for this study were collected from three ABET-accredited online undergraduate engineering programs at a large public university in the Southwestern United States: electrical engineering, engineering management, and software engineering. A total of 138 students participated in the study during the fall 2019 (n=85) and spring 2020 (n=53) semesters. Participants responded to surveys twice weekly during their 7.5-week online course. The survey asked students about their course perceptions related to instructor practices, peer support, and course difficulty level, their expectancies in completing the course, and their course persistence intentions. This work is part of a larger National Science Foundation-funded research project dedicated to studying online student course-level persistence based on both students' self-report data and course learning management system (LMS) activity. The survey sample was consistent with reports indicating that online learners tend to be more diverse than face-to-face learners. Findings from the path analysis revealed that students' perceptions of course LMS fit, perceived course difficulty, and expectancies of course success positively and significantly predicted persistence intentions, making them the most important influences. Expectancies of course success had a direct effect on persistence intentions. The findings underscore the need to elucidate further the mechanisms through which expectancies of success influence persistence.
