Research Problem: Climate change is one of the most important environmental, social, and economic issues of our time. The documented impacts of climate change are extensive. Climate change education can help students link this global issue to students’ everyday lives, foster a climate-literate public, and serve as motivation for action. Yet prior to instructional interventions, the first step in promoting conceptual change is to describe expert and novice conceptions or mental models of the topic (Treagust and Duit 2009). Published studies about students’ climate change knowledge primarily stem from the earth and atmospheric sciences, and focus on students’ knowledge of the mechanisms causing global warming and of the abiotic systems important to climate change. Limited research has documented undergraduate students’ knowledge about the biotic impacts of climate change. Our goal was to describe student/novice and instructor/expert conceptual knowledge of the biotic impacts of climate change. Research Design: We conducted interviews with 30 undergraduates and 10 instructors who are students or teaching in Introductory Biology or Ecology classes. Our semi-structured interview protocol probed participants’ conceptions of the mechanisms, outcomes and levels of impact that climate change has on the biological world. Participants were taken from varying institutions across the US (Baccalaureate, Master’s, and Doctoral). Analyses: Following transcription of all interviews, we used thematic coding analysis to describe novice and expert conceptions of the biotic impacts to climate change. We also compared across interview populations to describe how novice and expert conceptions compare. Contribution: Our findings contribute understanding of biology student and expert knowledge of the biotic impacts of climate change and contribute more broadly to the field of climate science where research on understanding of the biotic impacts of climate change is minimal. Our work will represent a novel perspective because most climate education research at the university-level has focused on earth and atmospheric science students. Further, this work is the first step in a larger project that aims to develop valid and reliable concept inventory related to biotic impacts of climate change – an instrument sorely needed to properly address improvements to climate change education.

Undergraduate student conceptions of climate change impacts on animals
Abstract Climate change is a critical environmental issue and is a recommended core concept in the Ecological Society of America’s 4‐Dimensional Ecology Education framework. Limited work describes K‐12 students’ conceptions of the biotic impacts of climate change, yet research is lacking to explore undergraduate students’ conceptions on this topic. Our goal was to describe undergraduate student conceptions of the biotic outcomes of climate change, and characterize how these student conceptions of animal responses to climate change align with accepted scientific ideas. We used an interpretive qualitative research design and interviewed 13 undergraduate students who were enrolled in either an introductory biology or general ecology course. Through two independent codings of the same dataset, we separately addressed each of our research goals. Prior to this study, we identified three general biotic outcomes from climate change, which were confirmed by outside experts: changes to an animal’s Growth and Survival, their Reproduction, or their Distribution. Our student interviewees as a whole mentioned all three of these outcomes, and most individuals mentioned all three in their responses. Additionally, we found that most student ideas were aligned with Scientific conceptions, while a third of student ideas contained some scientific conceptions but were incomplete. Only a small percent of conceptions voiced in our sample were identified as alternative conceptions that did not align with accepted scientific ideas. These findings are important for educators who teach climate change, as they suggest that undergraduate students come to our classes with productive resources; however, our findings also identify concepts where students may struggle or enter classrooms with a more incomplete understanding.

Recent work has shown that student trust in their instructor is a key moderator of STEM student buy-in to evidence-based teaching practices (EBTs), enhancing positive student outcomes such as performance, engagement, and persistence. Although trust in instructor has been previously operationalized in related settings, a systematic classification of how undergraduate STEM students perceive trustworthiness in their instructors remains to be developed. Moreover, previous operationalizations impose a structure that often includes distinct domains, such as cognitive and affective trust, that have yet to be empirically tested in the undergraduate STEM context. MethodsTo address this gap, we engage in a multi-step qualitative approach to unify existing definitions of trust from the literature and analyze structured interviews with 57 students enrolled in undergraduate STEM classes who were asked to describe a trusted instructor. Through thematic analysis, we propose that characteristics of a trustworthy instructor can be classified into three domains. We then assess the validity of the three-domain model both qualitatively and quantitatively. First, we examine student responses to determine how traits from different domains are mentioned together. Second, we use a process-model approach to instrument design that leverages our qualitative interview codebook to develop a survey that measures student trust. We performed an exploratory factor analysis on survey responses to quantitatively test the construct validity of our proposed three-domain trust model. Results and discussionWe identified 28 instructor traits that students perceived as trustworthy, categorized into cognitive, affective, and relational domains. Within student responses, we found that there was a high degree of interconnectedness between traits in the cognitive and relational domains. When we assessed the construct validity of the three-factor model using survey responses, we found that a three-factor model did not adequately capture the underlying latent structure. Our findings align with recent calls to both closely examine long-held assumptions of trust dimensionality and to develop context-specific trust measurements. The work presented here can inform the development of a reliable measure of student trust within undergraduate STEM student environments and ultimately improve our understanding of how instructors can best leverage the effectiveness of EBTs for positive student learning outcomes.more » « less

Undergraduate biology educators strive to understand how to best teach students the concepts of climate change. The root of this understanding is the establishment of what students know about climate change. This research aims to describe undergraduate biology students’ conceptions of climate change and their argument practices and associated cognitive biases in how they think about the topic. We used qualitative conception interviews to obtain data from 26 American biology undergraduate students who predicted how climate change would affect a forested ecosystem after an average of 1° increase in Fahrenheit (0.5°C change) over 25 years. Through deductive coding, we found the majority of students’ predictions agreed with expert ideas. However, the students used various argument strategies (i.e., Reasoning and Cognitive Biases) in defending their choices, including Ecological Explanations, Observations, Anchoring, and Contrast Effects.more » « less

Climate change is a major concern to undergraduate students. Understanding climate change relies on an understanding of polar regions. However, courses on polar regions are rare at undergraduate institutions. Polar ENgagement through GUided INquiry (PENGUIN) modules were designed to give students experience with polar research in a variety of standard courses, including physics, computer science, physical chemistry, and economics, through using course-specific and computational tools to analyze polar data. Here, we present a new PENGUIN module taught in a statistics class, in which students apply statistical tools to ice core data to reconstruct past temperature records. Quantitative student responses on pre- and post-surveys were collected in a quasi-experimental context to assess student knowledge gains for a test group of 91 students and a control group of 73 students (who did not complete the module). Test-group students made statistically significant increases of 25 to 46% on all six statistics questions, with a normalized gain of 56%. By contrast, control group statistics knowledge gains ranged from −4 to 25%, with statistically significant increases for only three questions and a normalized gain of 22%. For polar research questions, the test group demonstrated increases in correct responses to polar research questions (11 to 31%), with statistically significant improvements (p < .05) of 22-31% on 3 of 6 polar research questions. These findings support the conclusion that PENGUIN modules can successfully teach course concepts while increasing polar literacy.more » « less

Wessner, David R (Ed.)ABSTRACT Calls to increase undergraduate involvement in research have led to a significant increase in student participation via course-based undergraduate research experiences (CUREs). These CUREs provide students an authentic research experience, which often involves dissemination of research by public speaking. For instance, the First-year Research Immersion (FRI) program at Binghamton University is a three-semester CURE sequence that prepares students for scientific research and effective communication of their findings. After one semester of research, students from the FRI program are tasked with presenting their research to hundreds of faculty members, staff, friends, and family at the annual FRI poster session. However, our students, and undergraduates in general, report high anxiety and fear around public speaking such as this. To better prepare our students for public speaking at a research poster session, we developed a workshop that includes a novel role-play activity to mimic a fast-paced poster session or conference in order to address students' fears and increase confidence levels. The role-play activity gives students iterative practice such that they are prepared for the realities of a poster session including variation of poster attendees. During the activity, students switch roles between presenter and audience member. In the role of an audience member, students are given Pokèmon-like role-playing cards that explain the traits and abilities of various types of poster-goers that students might come across (faculty in and out of discipline, staff, family, friends, etc.). Students improvise and enact their card-assigned role as they engage with their classmates who are practicing their poster presentations. To assess student outcomes, students were given three surveys: pre-activity, post-activity, and post-poster presentation. Immediately following the activity, 64% of students reported the highest level of confidence, and following the poster session, 93% of students reported extreme confidence in their poster presentation abilities. These data show that this role-play activity can help address student confidence and better prepare students to communicate their research.more » « less
