Ripped from the Headlines: Using Current Events and Deliberative Democracy to Improve Student Performance in and Perceptions of Nonmajors Biology Courses.

ABSTRACT: Despite the importance of scientific literacy, many foundational science courses are plagued by low student engagement and performance. In an attempt to improve student outcomes, an introductory biology course for nonscience majors was redesigned to present the course content within the framework of current events and deliberative democratic exercises. During each instructional unit of the redesigned course, students were presented with a highly publicized policy question rooted in biological principles and currently facing lawmakers. Working in diverse groups, students sought out the information that was needed to reach an educated, rationalized decision. This approach models civic engagement and demonstrates the real-life importance of science to nonscience majors. The outcomes from two semesters in which the redesign were taught were compared with sections of the course taught using traditional pedagogies. When compared with other versions of the same course, presenting the course content within a deliberative democratic framework proved to be superior for increasing students' knowledge gains and improving students' perceptions of biology and its relevance to their everyday lives. These findings establish deliberative democracy as an effective pedagogical strategy for nonmajors biology.

Encouraging Science Communication through Deliberative Pedagogy: A Study of a Gene Editing Deliberation in a Nonmajors Biology Course.

Project description:Deliberative pedagogy encourages productive science communication and learning through engagement and discussion of socio-scientific issues (SSI). This article examines a two-day deliberation module on gene editing that took place in an introductory nonmajors biology course, furthering research on integrating deliberative discussion into the biology classroom. The results demonstrate the benefits of a single, episodic deliberation in the classroom, which can positively encourage active discussion and critical awareness of connections between biology and real-world issues, thus contributing to the development of scientific citizenship. Additionally, the findings show that gene editing is an apt SSI topic for the deliberative process because it encourages productive communication practices of scientific citizenship, including discussion, perspective taking, questioning, and consideration of different types of evidence when coming to a decision.

Alternative Realities: Faculty and Student Perceptions of Instructional Practices in Laboratory Courses.

Project description:Curricular reform efforts depend on our ability to determine how courses are taught and how instructional practices affect student outcomes. In this study, we developed a 30-question survey on inquiry-based learning and assessment in undergraduate laboratory courses that was administered to 878 students in 54 courses (41 introductory level and 13 upper level) from 20 institutions (four community colleges, 11 liberal arts colleges, and five universities, of which four were minority-serving institutions). On the basis of an exploratory factor analysis, we defined five constructs: metacognition, feedback and assessment, scientific synthesis, science process skills, and instructor-directed teaching. Using our refined survey of 24 items, we compared student and faculty perceptions of instructional practices both across courses and across instructors. In general, faculty and student perceptions were not significantly related. Although mean perceptions were often similar, faculty perceptions were more variable than those of students, suggesting that faculty may have more nuanced views than students. In addition, student perceptions of some instructional practices were influenced by their previous experience in laboratory courses and their self-efficacy. As student outcomes, such as learning gains, are ultimately most important, future research should examine the degree to which faculty and student perceptions of instructional practices predict student outcomes in different contexts.

Community engagement for big epidemiology: deliberative democracy as a tool.

Project description:Public trust is critical in any project requiring significant public support, both in monetary terms and to encourage participation. The research community has widely recognized the centrality of public trust, garnered through community consultation, to the success of large-scale epidemiology. This paper examines the potential utility of the deliberative democracy methodology within the public health research setting. A deliberative democracy event was undertaken in Tasmania, Australia, as part of a wider program of community consultation regarding the potential development of a Tasmanian Biobank. Twenty-five Tasmanians of diverse backgrounds participated in two weekends of deliberation; involving elements of information gathering; discussion; identification of issues and formation of group resolutions. Participants demonstrated strong support for a Tasmanian Biobank and their deliberations resulted in specific proposals in relation to consent; privacy; return of results; governance; funding; and, commercialization and benefit sharing. They exhibited a high degree of satisfaction with the event, and confidence in the outcomes. Deliberative democracy methodology is a useful tool for community engagement that addresses some of the limitations of traditional consultation methods.

Student Learning Outcomes and Attitudes Using Three Methods of Group Formation in a Nonmajors Biology Class.

Project description:Group work is often a key component of student-centered pedagogies, but there is conflicting evidence about what types of groups provide the most benefit for undergraduate students. We investigated student learning outcomes and attitudes toward working in groups when students were assigned to groups using different methods in a large-enrollment, student-centered class. We were particularly interested in how students entering the class with different levels of competence in biology performed in homogeneous or heterogeneous groups, and what types of group compositions were formed using different methods of group formation. We found that low-competence students had higher learning outcomes when they were in heterogeneous groups, while mid- and high-competence students performed equally well in both group types. Students of all competence types had better attitudes toward group work in heterogeneous groups. The use of student demographic variables to preemptively form groups and allowing students to self-select their group mates both yielded heterogeneous competence groups. Students in the instructor-formed, demographic groups had higher learning outcomes compared with students allowed to self-select. Thus, heterogeneous groupings provided the most benefit for students in our nonmajors, large-enrollment class.

Student Anxiety and Perception of Difficulty Impact Performance and Persistence in Introductory Biology Courses.

Project description:Students respond to classroom activities and achievement outcomes with a variety of emotions that can impact student success. One emotion students experience is anxiety, which can negatively impact student performance and persistence. This study investigated what types of classroom anxiety were related to student performance in the course and persistence in the major. Students in introductory biology classes self-reported their general class, test, communication, and social anxiety; perceived course difficulty; intention to stay in the major; and demographic variables. Final course grades were acquired from instructors. An increase in perception of course difficulty from the beginning to the end of the semester was significantly associated with lower final course grades (N = 337), particularly for females, non-Caucasians, and students who took fewer Advanced Placement (AP) courses. An increase in communication anxiety slightly increased performance. Higher general class anxiety at the beginning of the semester was associated with intention to leave the major (N = 122) at the end of the semester, particularly for females. Females, freshmen, and those with fewer AP courses reported higher general class anxiety and perceived course difficulty. Future research should identify which factors differentially impact student anxiety levels and perceived difficulty and explore coping strategies for students.

"Co-construction" in deliberative democracy: lessons from the French Citizens' Convention for Climate.

Project description:Launched in 2019, the French Citizens' Convention for Climate (CCC) tasked 150 randomly chosen citizens with proposing fair and effective measures to fight climate change. This was to be fulfilled through an "innovative co-construction procedure", involving some unspecified external input alongside that from the citizens. Did inputs from the steering bodies undermine the citizens' accountability for the output? Did co-construction help the output resonate with the general public, as is expected from a citizens' assembly? To answer these questions, we build on our unique experience in observing the CCC proceedings and documenting them with qualitative and quantitative data. We find that the steering bodies' input, albeit significant, did not impair the citizens' agency, creativity, and freedom of choice. While succeeding in creating consensus among the citizens who were involved, this co-constructive approach, however, failed to generate significant support among the broader public. These results call for a strengthening of the commitment structure that determines how follow-up on the proposals from a citizens' assembly should be conducted.

Don't Joke About Me: Student Identities and Perceptions of Instructor Humor in College Science Courses.

Project description:Humor is a popular tool used by instructors to engage students. However, some instructor jokes may be perceived as less funny and more offensive by particular groups of students. Previous studies have shown that student gender impacts student perception of instructor humor; however, to our knowledge no studies have explored whether there are differences in how other identity groups interpret instructor humor. In this study, we surveyed 1,637 students across 25 different college science courses at a research-intensive institution in the Southwest United States. Students evaluated a set of topics that science instructors might joke about in class as to whether they were funny and offensive. Using binary logistic regression, we analyzed whether students of different identities, including race/ethnicity, political affiliation, LGBTQ+ status, religious affiliation, and native language, differentially perceived joke topics to be funny and offensive if told by an instructor in class. We identified that topics which tended to be perceived by students as funny rather than offensive were generally less likely to be perceived as funny to non-native English language speakers compared with native English speakers. We also found that students were more likely to be offended by jokes about their own identity group. This work identifies potentially humorous topics that instructors should avoid because they could be offensive to groups of students. This study also highlights topics that tend to be perceived as funny to most students, which indicates that instructors who joke about such topics may be universally benefitting college science students.

Active learning not associated with student learning in a random sample of college biology courses.

Project description:Previous research has suggested that adding active learning to traditional college science lectures substantially improves student learning. However, this research predominantly studied courses taught by science education researchers, who are likely to have exceptional teaching expertise. The present study investigated introductory biology courses randomly selected from a list of prominent colleges and universities to include instructors representing a broader population. We examined the relationship between active learning and student learning in the subject area of natural selection. We found no association between student learning gains and the use of active-learning instruction. Although active learning has the potential to substantially improve student learning, this research suggests that active learning, as used by typical college biology instructors, is not associated with greater learning gains. We contend that most instructors lack the rich and nuanced understanding of teaching and learning that science education researchers have developed. Therefore, active learning as designed and implemented by typical college biology instructors may superficially resemble active learning used by education researchers, but lacks the constructivist elements necessary for improving learning.

A Call to Develop Course-Based Undergraduate Research Experiences (CUREs) for Nonmajors Courses.

Project description:Course-based undergraduate research experiences (CUREs) for non-science majors (nonmajors) are potentially distinct from CUREs for developing scientists in their goals, learning objectives, and assessment strategies. While national calls to improve science, technology, engineering, and mathematics education have led to an increase in research revealing the positive effects of CUREs for science majors, less work has specifically examined whether nonmajors are impacted in the same way. To address this gap in our understanding, a working group focused on nonmajors CUREs was convened to discuss the following questions: 1) What are our laboratory-learning goals for nonmajors? 2) What are our research priorities to determine best practices for nonmajors CUREs? 3) How can we collaborate to define and disseminate best practices for nonmajors in CUREs? We defined three broad student outcomes of prime importance to the nonmajors CURE: improvement of scientific literacy skills, proscience attitudes, and evidence-based decision making. We evaluated the state of knowledge of best practices for nonmajors, and identified research priorities for the future. The report that follows is a summary of the conclusions and future directions from our discussion.

Active learning and student-centered pedagogy improve student attitudes and performance in introductory biology.

Project description:We describe the development and implementation of an instructional design that focused on bringing multiple forms of active learning and student-centered pedagogies to a one-semester, undergraduate introductory biology course for both majors and nonmajors. Our course redesign consisted of three major elements: 1) reordering the presentation of the course content in an attempt to teach specific content within the context of broad conceptual themes, 2) incorporating active and problem-based learning into every lecture, and 3) adopting strategies to create a more student-centered learning environment. Assessment of our instructional design consisted of a student survey and comparison of final exam performance across 3 years-1 year before our course redesign was implemented (2006) and during two successive years of implementation (2007 and 2008). The course restructuring led to significant improvement of self-reported student engagement and satisfaction and increased academic performance. We discuss the successes and ongoing challenges of our course restructuring and consider issues relevant to institutional change.
