Science Identity and Its Implications for STEM Retention and Career Aspirations Through a Research-Based First-Year Biology Seminar
Journal of College Science Teaching—September/October 2022 (Volume 52, Issue 1)
By Krista L. Lucas and Alexis D. Spina
There are more STEM jobs than there are qualified graduates to fill these positions, and recruiting students into STEM majors is insufficient. Of students who enter college intending to pursue STEM, nearly half do not finish their STEM degrees. In this article, we focus on retaining students who enter college with a declared biology major. This qualitative study examines this retention issue through the lens of identity theory, situated learning, and constructivism in the context of a research-focused biology first-year seminar at a small, private university. It was found that the six participants felt more like scientists at the conclusion of the semester-long seminar, and all were planning to remain in STEM career pathways.

A Design Heuristic for Analyzing and Interpreting Data
Journal of College Science Teaching—September/October 2022 (Volume 52, Issue 1)
By Sandra Swenson, Yi He, Heather Boyd, and Kate Schowe Good
Students reasoning with data in an authentic science environment had the opportunity to learn about the process of science and the world around them while developing skills to analyze and interpret self-collected and secondhand data. Our results show that nearly 50% of the treatment group responses were accurate when describing the reason for measuring water parameters, compared with 26% in the traditional lab group. When pre- and post-survey scores were compared, students in the treatment group outperformed students in the traditional group on four items: making claims about water pollution based on data; understanding water pollution in the Hudson River; understanding the relationship between temperature, pH, and salinity values; and feeling prepared to justify their reasoning on water pollution. Our evidence points to greater engagement by the treatment group and stronger descriptions about their claims, evidence, and reasoning around measuring water parameters and potential water pollution problems.

Active Learning Classrooms
Addressing Learning Differences in Large-Enrollment Introductory Science Courses
Journal of College Science Teaching—September/October 2022 (Volume 52, Issue 1)
By Carolyn Hushman, Aurora Pun, and Sushilla Knottenbelt
Active learning classrooms (ALCs) are designed to support collaborative learning in large class sections that are often taught with a lecture format. Studies on ALCs indicate that they have positive influences on student learning, but the same studies fail to look at learning differences between subgroups of students. In the current study, students enrolled in an introductory STEM course (N = 273) instructed in ALCs completed learning inventories and questionnaires designed to measure the influence of social context. Results showed a lack of learning differences within the classroom environment, a positive relationship between learning gains and perceptions of the student-student interactions, and differences in the perception of the social context unique to ALCs based on gender and ethnic and racial diversity.

Aligning Undergraduate Science Curricula With Three-Dimensional Learning
Journal of College Science Teaching—September/October 2022 (Volume 52, Issue 1)
By Jeffrey Radloff, Brenda Capobianco, Jessica Weller, Sanjay Rebello, David Eichinger, and Kendra Erk
Recent science reform advocates for the inclusion of engineering design to teach science and represents a shift to so-called three-dimensional (3D) learning. This shift often requires science instructors to adapt their current curriculum to integrate 3D learning. To support this shift, the current study illustrates the collaborative development and use of a rubric for aligning existing curriculum with new reform. Collaborators include three undergraduate science content course (i.e., biology, chemistry, and physics) instructors who used the tool to adapt their current curriculum. In this article, we outline the phases of tool development and showcase its implementation by the chemistry content course instructor to integrate a rocket design task. Successes and considerations are discussed as they relate to science teacher education and professional learning.

Reflections on Multimodal Delivery of a Laboratory Course for Nonscience Majors and Opportunities for Improved Student Engagement
Journal of College Science Teaching—September/October 2022 (Volume 52, Issue 1)
By Mark Vincent dela Cerna
A rudimentary level of scientific literacy is necessary in the general public. At the undergraduate level, this literacy can be achieved through general education courses offered in areas of natural sciences. Over the past several years, practical courses have been developed to make the teaching of chemistry concepts in the laboratory more interesting and appealing to nonscience majors. This article provides insights and reflections from teaching a general education, liberal arts chemistry course at a private university using different teaching delivery modes during a pandemic. Specifically, the unique circumstances of the COVID-19 pandemic allowed faculty to deviate from the traditional face-to-face delivery and explore the use of virtual delivery, experimentation at home, and hybrid instruction to meet learning objectives. The article reflects on the lessons from this experience to improve course delivery and student engagement in science laboratory courses for nonscience majors.

A Course-Based Research and Teaching Experience for Science Majors and Preservice Educators
Journal of College Science Teaching—September/October 2022 (Volume 52, Issue 1)
By Timothy Stewart, Janette Thompson, Kristina Tank, Joanne Olson, Michael Rentz, and Peter Wolter
We designed a course to provide undergraduate science students and preservice teachers with authentic research and teaching experiences. Teams of students and preservice teachers complete supervised field ecology research projects and develop teaching activities based on their research in order to learn practices in both science and science teaching while improving skills in collaboration, leadership, and different forms of communication. Students apply their learning by educating local school groups on ecological concepts in the field and share their scholarship with faculty, peers, and community partners during a poster symposium. Each student team completes a research project and teaching activity proposal, conducts research and develops a teaching activity, and writes a research paper and lesson plan in the format of a professional manuscript. Teams use mentor feedback and their reflections on drafts and practice sessions to improve the research proposal and paper, teaching lesson plan, delivery of the teaching activity, and poster presentation.

That’s How the Kangaroo Bounces
A Biological Case Study to Teach Energy Concepts
Journal of College Science Teaching—September/October 2022 (Volume 52, Issue 1)
By Erin M. Craig, Sydney Galbreath, Timothy Sorey, and Derek Ricketson
A growing number of Introductory Physics for Life Sciences courses have been developed to prepare biology, premedicine, and pre-health majors for cross-disciplinary connections between physical principles and biological systems. Many students find it challenging to apply idealized algebra-based general physics to more complex biological systems. A novel biological case study was developed to teach undergraduates to expand their energy transformation analysis of a simple system—a bouncing ball—to a more complex biological system of a kangaroo hopping. Similar to a ball, kangaroos transform elastic potential energy into kinetic energy to power their “bouncing.” Unlike the bouncing ball, kangaroos gain additional potential energy through metabolic processes. Students follow a sequence of guided tutorials that facilitate small-group learning as they evaluate quantitative data from video analysis with metabolic energy expenditures from literature to synthesize a real-world understanding of energy transformations. In this article, we describe learning progressions, practical tips for teaching, and lessons learned in this activity covering energy transformations.

Teaching and Learning About Global Climate Change Online
Journal of College Science Teaching—September/October 2022 (Volume 52, Issue 1)
By Emily van Zee, Elizabeth Gire, Kelby T. Hahn, and Mackenzie Belden
Sessions of our laboratory-based physics course have been “meeting” synchronously online instead of on campus due to the pandemic. Shifting to remote instruction prompted us to create online versions of the course. In the unit on global climate change, for example, we continued engaging students in documenting their initial and evolving ideas; exploring the greenhouse effect; examining evidence of increasing global temperatures, rising sea levels, and melting glaciers; modeling causes of rising sea levels; considering ways individuals, communities, states, nations, and international organizations are taking action; and making connections to education policies such as the Next Generation Science Standards. Key aspects of this course have been creating opportunities for formative assessment and fostering a sense of community.

Catalyzing the Advancement of Diversity, Equity, and Inclusion in Chemical Education
Journal of College Science Teaching—September/October 2022 (Volume 52, Issue 1)
By Reginald Rogers and Todd Pagano
Only a relatively small number of students from underrepresented groups enter the field of chemistry, complete their degrees, and enter the workforce. There are ethical and practical concerns when we lose out on diversifying the chemical sciences and benefitting from the greater contributions of thinkers from diverse backgrounds working together in the classroom and workplace. The principles of diversity, equity, and inclusion are critical for resolving the current imbalance. Continuous reflection by faculty is an essential component for the improvement process, as are understanding value and embracing change. Strategies for making students feel a sense of belonging in a course, research laboratory, and discipline include ensuring the educational climate is safe, accessible, and respectful; making the learning experience relatable and providing access to role models; and providing research experiences and exposure to the field. While the focus of this Point of View is on chemical education, the conversation and best practices are applicable and extend to teaching and mentoring in other fields of science.
