Role of Mindfulness Practices in the College Classroom

The following study examined the effect of mindful practices on college student attitudes and learning comprehension using two sections of an introductory biology course taught by the same instructor. One section used lecture complemented with active learning formats while the other section additionally included mindful practices. Comparisons were made between the students’ surveys and quiz/exam scores. Students in the mindful section also kept journals. Results showed no significant differences in quiz and exam scores between the two groups; however, students in the mindfulness section found value in the practices both in and outside the classroom. Students reported a gain in their attitude towards the value of mindfulness practices as well as the use of mindfulness practices and reported a decrease in anxiety levels. Students identified these practices as helping them with focused attention, peace, and relaxation. At the end of the semester, over 90% of students agreed that mindfulness has a valuable place in the college classroom.

Understanding Differences in Underrepresented Minorities and First-Generation Student Perceptions in the Introductory Biology Classroom

We used quantitative methods to better understand the perceptions of students in an introductory biology course (Biology 101) at a small, liberal arts college (SLAC) that is also a primarily white institution (PWI). In pre/post surveys, we asked students questions related to their attitudes and beliefs about their professor, classmates, and Biology 101.

Persistent Miscalibration for Low and High Achievers despite Practice Test Feedback in an Introductory Biology Course

Students’ ability to accurately judge their knowledge is crucial for effective learning. However, students’ perception of their current knowledge is often misaligned with their actual performance.

Development of an Online General Biology Open Educational Resource (OER) Laboratory Manual

Currently, many academic institutions are using one or more variations of online modalities due to the COVID-19 pandemic, and science educators face a unique challenge with distance-learning laboratories. Many resources to engage students in virtual, interactive laboratory activities exist, but we found that high costs and/or overlooked content left gaps for several topics typically taught in a general, introductory biology course for undergraduate biology majors (e.g., organismal biology).

Student Association of Lecture Content with the Five Core Concepts of Biology: Novel Results from an Introductory Biology Course

Challenges in integration of concepts persist among undergraduate biology students. The 5 core concepts (5CCs) of biology presented in Vision and Change provide a comprehensive, concept-based description of the knowledge of biology, summarized in five main biological scales and five overarching principles that dictate natural biological phenomena and processes.

A comparison study of human examples vs. non-human examples in an evolution lesson leads to differential impacts on student learning experiences in an introductory biology course

Background Instructors can teach evolution using any number of species contexts. However, not all species contexts are equal, and taxa choice can alter both cognitive and affective elements of learning. This is particularly true when teaching evolution using human examples, a promising method for evolution instruction that nevertheless comes with unique challenges. In this study, we tested how an evolution lesson focused on a human example may impact students’ engagement, perceived content relevance, learning gains, and level of discomfort, when compared to the same lesson using a non-human mammal example. We use this isomorphic lesson and a pre-post study design administered in a split-section introductory biology classroom to isolate the importance of the species context. Results For two of the four measurements of interest, the effect of using human examples could not be understood without accounting for student background. For learning gains, students with greater pre-class content knowledge benefited more from the human examples, while those with low levels of knowledge benefited from the non-human example. For perceived relevance, students who were more accepting of human evolution indicated greater content relevance from the human example. Regardless of condition, students with lower evolution acceptance reported greater levels of discomfort with the lesson. Conclusions Our results illustrate the complexities of using human examples to teach evolution. While these examples were beneficial for many students, they resulted in worse outcomes for students that were less accepting of evolution and those who entered the course with less content knowledge. These findings demonstrate the need to consider diverse student backgrounds when establishing best practices for using human examples to teach evolution.

In an "ecological-belonging" intervention to reduce inequities in STEM, context matters

Doubts about belonging in the classroom are often shouldered disproportionately by students from historically marginalized groups, which can lead to underperformance. Ecological-belonging interventions use a classroom-based activity to instill norms that adversity is normal, temporary and surmountable. Building on prior studies, we sought to identify the conditions under which such interventions are effective. In a chemistry course (Study 1), students from underrepresented ethnic backgrounds underperformed relative to their peers in the absence of the intervention. This performance gap was eliminated by the intervention. In an introductory biology course (Study 2), there were no large performance gaps in the absence of the intervention, and the intervention had no effect. Study 2 also explored the role of the instructor that delivers the intervention. The intervention boosted scores in classrooms of instructors with a fixed (versus growth-oriented) intelligence mindset. Our results suggest that ecological-belonging interventions are more effective in more threatening classroom contexts.
