In a large ( n =383) mixed methods study in a community college, students in classes that use warm random call report benefits (e.g., engagement, eustress) and drawbacks of being called on (e.g., distress, anxiety), and perceive more peer interaction. This urges continued investigation of warm random call and possible context-dependent effects. 

Limited data are available on the differential impacts course-based undergraduate research experiences (CUREs) have on subpopulations of community college (CC) students, including those in allied health, career and technical education, and nursing pathways (workforce). This essay addresses CC demographics, student success, and assessment practices for CUREs. 

This paper examines the extent to which community college biology education research (CC BER) has progressed since initial calls for broadening participation by comparing the number of CC BER publications, identifies barriers to and opportunities for community college faculty BER participation, and highlights the importance of institutional networks as a driver for incorporating CC faculty in BER. 

Recent calls in biology education research (BER) have recommended that researchers leverage learning theories and methodologies from other disciplines to investigate the mechanisms by which students to develop sophisticated ideas. We suggest design-based research from the learning sciences is a compelling methodology for achieving this aim. Design-based research investigates the “learning ecologies” that move student thinking toward mastery. These “learning ecologies” are grounded in theories of learning, produce measurable changes in student learning, generate design principles that guide the development of instructional tools, and are enacted using extended, iterative teaching experiments. In this essay, we introduce readers to the key elements of design-based research, using our own research into student learning in undergraduate physiology as an example of design-based research in BER. Then, we discuss how design-based research can extend work already done in BER and foster interdisciplinary collaborations among cognitive and learning scientists, biology education researchers, and instructors. We also explore some of the challenges associated with this methodological approach. 

Two foundational concepts in biology education are 1) offspring are not identical to their parents, and 2) organisms undergo changes throughout their lives. These concepts are included in both international and U.S. curricular standards. Research in psychology has shown that children often have difficulty understanding these concepts, as they are inconsistent with their intuitive theories of the biological world. Additionally, prior research suggests that diagrams are commonly used in instruction and that their features influence student learning. Given this prior work, we explored the characteristics of life cycle diagrams and discuss possible implications for student learning. We examined 75 life cycle diagrams from books, including five biology or general science textbooks and 25 specialized trade books focusing on biology for children. We also examined 633 life cycle diagrams from a publicly available online database of science diagrams. Most diagrams failed to show any within-species variability. Additionally, many diagrams had perceptually rich backgrounds, which prior research suggests might hinder learning. We discuss how the design characteristics of diagrams may reinforce students’ intuitive theories of biology, which might make it difficult for students to understand key biological concepts in the future.
