Dose-Response in Context: A Backward Design, Inquiry Activity Workshop for College Transfer Students

The Workshops for Engineering and Science Transfers (WEST) program was designed to foster critical-thinking skills and develop a supportive community for new Science, Technology, Engineering, and Mathematics (STEM) community college transfer students at the University of California, Santa Cruz, with the ultimate goal of improving student retention and persistence in STEM. All learners in the program participate in inquiry activities devised to incorporate elements of backward design and equity and inclusion. Here we discuss our 2019 Toxicology WEST workshop activity, an in-depth exploration of dose-response relationships created to provide an overview of the field of toxicology and clarify common misconceptions. To reflect authentic research design, we had learners assume the roles of Environmental Protection Agency (EPA) scientists tasked with investigating the effects of environmental toxicants on the model organisms Caenorhabditis elegans and Daphnia magna. Learners were asked to design and conduct experiments to explore the dose-response relationship and report their results in a culminating poster symposium. We assessed learning by evaluating their performance on two tasks: an individual written response and a group poster presentation. Our activity gave learners an opportunity to practice experimental design, data analysis, and science communication before beginning UCSC STEM courses. Practicing these skills early is essential for student retention in STEM, as many students find the experimental process challenging. Here, we describe details of our inquiry workshop activity, reflect on the effectiveness of the activity and our assessment of student learning, and offer suggestions for facilitation and adaptation of our activity to additional educational contexts

Utilizing Equitable and Inclusive Design Principles to Promote STEM Identity of Community College Transfer Students

Research suggests that developing an identity as a person in STEM is necessary for learners from marginalized groups to persist in STEM education and careers. These learners may perceive that their race, gender, or other characteristics make it difficult for their peers and supervisors to recognize them as scientists or engineers, thus disrupting their ability to maintain successful degree progress and to pursue their STEM career aspirations. Here we discuss the specific ways we designed inquiry workshops to not only clarify difficult core STEM content, but to also promote learners’ competence, performance, and targeted recognition as scientists. Our workshops were designed for students interested in chemistry, climate science, physics, and toxicology at the University of California, Santa Cruz (UCSC), Workshops for Engineering & Science Transfers (WEST) 2019 program. In designing our workshops, we focused on promoting the scientific identities of our learners by incorporating authentic ways for students to receive recognition from both peers and instructional facilitators, as well as allowing students to tap into their own personal interests and values. Insights from our designed assessments for learners’ understanding of our content demonstrate the success of our initiatives and provide further areas of improvement. Our goals are to create inclusive workshops to support students from all backgrounds, with emphasis on underrepresented backgrounds (community college, first generation, students of color, women, and LGBTQ+ students, etc.) as well as support them in other contexts, such as when mentoring STEM students in academic laboratory settings
