Biology education researchers seek to improve biology education, particularly at the introductory level, yet there is little documentation about what is actually happening in introductory biology. To characterize the landscape of learning expectations for introductory biology, we analyzed course-level learning objectives (n = 1108) and course…

Students often experience science, technology, engineering, and mathematics (STEM) courses as competitive, weed-out spaces. Learning Assistants (LAs) have potential to improve students' experiences in these courses. Previously, we elucidated themes describing the impact of LAs on students' sense of STEM belonging and science-related confidence in…

Course-based undergraduate research experiences (CUREs) have been proposed as a mechanism to democratize access to the benefits of apprentice-style scientific research to a broader diversity of students, promoting inclusivity and increasing student success and retention. As we evaluate CUREs, it is essential to explore their effectiveness within…

Student impressions formed during the first day of class can impact course satisfaction and performance. Despite its potential importance, little is known about how instructors format the first day of class. Here, we report on observations of the first day of class in 23 introductory science, technology, engineering, and math (STEM) courses. We…

Office hours are a part of nearly all science, technology, engineering, and mathematics (STEM) courses, with many academic and affective benefits for students who attend. However, despite their ubiquity, there has only been limited past work examining the sources of knowledge students draw from to shape their perceptions of office hours, as well…

We explored the impacts of a mathematics prerequisite on student success in Introductory Biology, focusing on students historically underserved in science, technology, engineering, and mathematics (STEM). Specifically, we studied Introductory Biology student outcomes 5 years before and 6 years after adding the prerequisite. Students who had not…

High levels of student anxiety are negatively related to degree persistence, academic achievement, and student perceptions of instructor support. Anxiety levels vary along many axes--among classes, within students in the same class, and over time--creating a dynamic emotional landscape in classrooms. In this study, we examined the relationship…

Introductory biology is a gateway course for majors and other science, technology, engineering, and mathematics (STEM) disciplines. Despite the importance of chemistry content knowledge for understanding biology, the relationship between chemistry knowledge and prior coursework and biology course performance is understudied. We used an opportunity…

Student self-efficacy, their confidence to successfully perform a task, is positively related to course performance. Students with high self-efficacy for a task are more motivated toward that task. Yet few studies have measured students' self-efficacy and motivation levels after exams are returned in introductory biology classes or studied how…

We developed labs on the evolution of antibiotic resistance to assess the costs and benefits of replacing traditional laboratory exercises in an introductory biology course for majors with a course-based undergraduate research experience (CURE). To assess whether participating in the CURE imposed a cost in terms of exam performance, we implemented…

Evolution is controversial among students and religiosity, religious affiliation, understanding of evolution, and demographics are predictors of evolution acceptance. However, quantitative research has not explored the unique impact of student perceived conflict between their religion and evolution as a major factor influencing evolution…

In this exploratory mixed-methods analysis of students' perceptions of inclusion in introductory STEM courses for STEM majors, we asked students to rate inclusion in their class and to provide an open-text explanation of their rating. Analyzing 1930 qualitative responses resulted in a codebook containing academic, identity, and nonspecific…

Instructors often provide feedback to their class in multiple ways. One way is through their follow-up behaviors, which are the specific strategies instructors implement after active learning activities. These behaviors could play an important role in student learning as students receive feedback from the instructor. However, there is little…

Students struggle to regulate their learning during independent study sessions. In this study, we ask whether an online behavioral intervention helped introductory students decrease distraction while studying. The intervention consisted of exam 1 reflection, exam 2 planning, and exam 2 reflection exercises. During planning, students formed a goal,…

Scientist Spotlights are homework assignments that highlight the personal and scientific stories of counterstereotypical scientists. Previous research has focused on whether these assignments promote possible selves in STEM (science, technology, engineering, mathematics). We sought to understand the value students themselves placed on the…
