Cultivating scientific literacy and a sense of place through course‐based urban ecology research

Undergraduate research experiences have been shown to increase engagement, improve learning outcomes, and enhance career development for students in ecology. However, these opportunities may not be accessible to all students, and incorporating inquiry‐based research directly into undergraduate curricula may help overcome barriers to participation and improve representation and inclusion in the discipline. The shift to online instruction during the COVID‐19 pandemic has imposed even greater challenges for providing students with authentic research experiences, but the pandemic may also provide a unique opportunity for creative projects conducted remotely. In this paper, I describe a course‐based undergraduate research experience (CURE) designed for an upper‐level ecology course at California State University, Dominguez Hills during remote learning. The primary focus of student‐led research activities was to explore the potential impacts of the depopulation of campus during the pandemic on urban coyotes (Canis latrans), for which there were increased sightings reported during this time. Students conducted two research studies, including an evaluation of urban wildlife activity, behavior, and diversity using camera traps installed throughout campus and analysis of coyote diet using data from scat dissections. Students used the data they generated and information from literature reviews, class discussions, and meetings with experts to develop a coyote monitoring and management plan for our campus and create posters to educate the public. Using the campus as a living laboratory, I aimed to engage students in meaningful research while cultivating a sense of place, despite being online. Students’ research outcomes and responses to pre‐ and post‐course surveys highlight the benefits of projects that are anchored in place‐based education and emphasize the importance of ecological research for solving real‐world problems. CUREs focused on local urban ecosystems may be a powerful way for instructors to activate ecological knowledge and capitalize on the cultural strengths of students at urban universities.     

Science Classroom Inquiry (SCI) Simulations: A Novel Method to Scaffold Science Learning

Science education is progressively more focused on employing inquiry-based learning methods in the classroom and increasing scientific literacy among students. However, due to time and resource constraints, many classroom science activities and laboratory experiments focus on simple inquiry, with a step-by-step approach to reach predetermined outcomes. The science classroom inquiry (SCI) simulations were designed to give students real life, authentic science experiences within the confines of a typical classroom. The SCI simulations allow students to engage with a science problem in a meaningful, inquiry-based manner. Three discrete SCI simulations were created as website applications for use with middle school and high school students. For each simulation, students were tasked with solving a scientific problem through investigation and hypothesis testing. After completion of the simulation, 67% of students reported a change in how they perceived authentic science practices, specifically related to the complex and dynamic nature of scientific research and how scientists approach problems. Moreover, 80% of the students who did not report a change in how they viewed the practice of science indicated that the simulation confirmed or strengthened their prior understanding. Additionally, we found a statistically significant positive correlation between students’ self-reported changes in understanding of authentic science practices and the degree to which each simulation benefitted learning. Since SCI simulations were effective in promoting both student learning and student understanding of authentic science practices with both middle and high school students, we propose that SCI simulations are a valuable and versatile technology that can be used to educate and inspire a wide range of science students on the real-world complexities inherent in scientific study.     

Innovation in teaching and learning invertebrate zoology in remote and online classrooms

The COVID‐19 global pandemic caused instructors to pivot to remote and online teaching, an especially challenging task in hands‐on classes such as invertebrate biology. In this special 25th anniversary issue of Invertebrate Biology, the authors present a variety of clever and effective ways to help invertebrate biology instructors adapt to teaching in an online environment. Student‐centered research and learning are essential in all biology classes, and we explore scientific writing, field trips, do‐it‐yourself laboratories, and more. These techniques will be useful for classes of varying sizes and types, from non‐major undergraduates to graduate students, even after the pandemic is over. Innovation for teaching invertebrate biology online may help facilitate more inclusive courses that serve diverse students more equitably. Ideas for how to best move traditionally hands‐on laboratories into online or remote formats are currently also being informally discussed in a collaborative online space for instructors.     

Taking practical learning in STEM education home: Examples from do‐it‐yourself experiments in plant biology

Practical teaching can give authentic learning experiences and teach valuable skills for undergraduate students in the STEM disciplines. One of the main ways of giving students such experiences, laboratory teaching, is met with many challenges such as budget cuts, increased use of virtual learning, and currently the university lockdowns due to the COVID‐19 pandemic. We highlight how at‐home do‐it‐yourself (DIY) experiments can be a good way to include physical interaction with your study organism, system, or technique to give the students a practical, authentic learning experience. We hope that by outlining the benefits of a practical, at‐home, DIY experiment we can inspire more people to design these teaching activities in the current remote teaching situation and beyond. By contributing two examples in the field of plant biology we enrich the database on experiments to draw inspiration from for these teaching methods.     

Student exam performance in flipped classroom sections is similar to that in active learning sections,and satisfaction with the flipped classroom hinges on attitudes toward learning from videos

ABSTRACT

The flipped classroom is a teaching innovation in which instructional content is delivered out of the classroom, often via videos, and the class period is used for application of the course material. While the popularity of the flipped classroom is growing exponentially, its benefits have not been extensively studied. In this study we compared three semesters of an undergraduate Genetics course that was non-flipped, but included a significant amount of active learning, to three semesters of a flipped course with the same content. Student exam performance was not statistically different between the active non-flipped and the flipped courses, suggesting that the benefits of the flipped environment may be similar to those achieved via active learning. We also examined student attitudes toward the flipped classroom, and found 56% of students were satisfied, 39% were dissatisfied, and 5% were neutral toward the flipped classroom. Our survey revealed that the clearest defining characteristic of dissatisfied students was not a dislike of classroom active learning activities. Rather, dissatisfied students disproportionately disliked, and had difficulty learning the course material, from videos.     

Online but not remote: Adapting field‐based ecology laboratories for online learning

Teaching ecology effectively and experientially has become more challenging for at least two reasons today. Most experiences of our students are urban, and we now face the near immediate and continuing need to deliver courses (either partially or wholly) online because of COVID‐19. Therefore, providing a learning experience that connects students to their environment within an ecological framework remains crucial and perhaps therapeutic to mental health. Here, we describe how prior to the pandemic we adapted our field‐based laboratories to include data collection, analysis, and interpretation, along with the development of a citizen‐science approach for online delivery. This design is simple to implement, does not require extensive work, and maintains the veracity of original learning outcomes. Collaboration online following field data collection in ecology courses within the context of cities offers further options to adapt to student experience levels, resource availability, and accessibility, as well as bringing instructors and students together to build an open well‐curated data set that can be used in ecology courses where no laboratories are available. Finally, it promotes an open collaboration among ecology instructors that can drive lasting conversations about ecology curriculum.     

Next-generation teaching: a template for bringing genomic and bioinformatic tools into the classroom

The recent increase in accessibility and scale of genetic data available through next-generation sequencing (NGS) technology has transformed biological inquiry. As a direct result, the application and analysis of NGS data has quickly become an important skill for future scientists. However, the steep learning curve for applying NGS technology to biological questions, including the complexity of sample preparation for sequencing and the analysis of large data sets, are deterrents to the integration of NGS into undergraduate education. Here, we present a course-based undergraduate research experience (CURE) designed to aid in overcoming these limitations through NGS investigations of prokaryotic diversity. Specifically, we use 16S rRNA sequencing to explore patterns of diversity stemming from student-directed hypothesis development. This CURE addresses three learning objectives: (1) it provides a forum for experimental design hypothesis generation, (2) it introduces modern genomic tools through a hands-on experience generating an NGS data-set, and (3) it provides students with an introductory experience in bioinformatics.     

Student‐led field studies of herbivory: Hands‐on experiences for remote (or in‐person) learning

Challenging students to independently design and implement experiments is a powerful way to teach the scientific method while engaging with STEM‐related course material. For ecology and organismal biology, such experiences often take the form of field work. The COVID‐19 pandemic presented formidable challenges for instructors of such courses: How can students conduct any experiments, much less ones of their own design, when they might not even have access to campus? Here we describe a student‐led field project exploring invertebrate herbivory in terrestrial plant systems. Designed to flexibly accommodate student groups working either in‐person, remotely, or both, the project would be suitable for invertebrate biology, plant biology, or general ecology courses at the college or high school level. We describe our implementation in two sections of a sophomore‐level course, provide specific advice based on our experiences, make suggestions for future improvements or adaptations, and provide all the written materials that instructors would need to implement this in their own teaching.     

Broadening the voice of science: Promoting scientific communication in the undergraduate classroom

Effective and accurate communication of scientific findings is essential. Unfortunately, scientists are not always well trained in how to best communicate their results with other scientists nor do all appreciate the importance of speaking with the public. Here, we provide an example of how the development of oral communication skills can be integrated with research experiences at the undergraduate level. We describe our experiences developing, running, and evaluating a course for undergraduates that complemented their existing undergraduate research experiences with instruction on the nature of science and intensive training on the development of science communication skills. Students delivered science talks, research monologues, and poster presentations about the ecological and evolutionary research in which they were involved. We evaluated the effectiveness of our approach using the CURE survey and a focus group. As expected, undergraduates reported strong benefits to communication skills and confidence. We provide guidance for college researchers, instructors, and administrators interested in motivating and equipping the next generation of scientists to be excellent science communicators.     

The associations between social-media use and academic performance among undergraduate students in biology

Recent studies have been conducted in regards to the use of social- media by students and how it can impact his/her academic performance. However, much of this research has been focused on how to use social-media websites in the classroom to facilitate student learning. Therefore, we aimed to address how the use of social-media can be either beneficial or detrimental to undergraduate students, with respect to their academic performance. We distributed a survey to 234 participants, all attending the same four-year university. Throughout the survey, the students self-reported their grade point average (GPA), study habits, and social-media use. We established that female students use social-media websites more often than their male peers, and using a Pearson’s correlation, we found that GPA negatively correlated with the number of social-media websites to which students subscribe (p < 0.05). Furthermore, we found that using more social-media websites correlated positively with the amount of time students spend using social-media platforms on a daily basis. Although previous studies indicate that social-media websites should be incorporated into the classroom, our results suggest that this addition may have negative effects on the study habits and academic performance of undergraduate students, particularly those within the field of biological sciences.     

Resolving spatial and temporal patterns of coral bleaching risk using image analysis: an active learning experience to improve climate change literacy in college students

Recent studies indicate poor understanding of the causes and consequences of climate change among college students. In an effort to improve climate change literacy, we have developed an authentic research experience for upper level undergraduate students focused on resolving spatial and temporal patterns of coral reef bleaching, an ecologically and economically important consequence of climate warming. In the research, students use a public archive of maps generated by the United States National Oceanographic and Atmospheric Association (NOAA) that use coloration to depict ocean areas experiencing above-average surface temperatures and where corals are at an increased risk of bleaching. Students are required to quantify the total area of coloration on individual maps using open-source image analysis software called Image J. By quantifying coloration (ie bleaching risk) over a large number of maps in a chronological sequence, students can test hypotheses regarding the relationship between ongoing climate warming and coral bleaching risk. Students are required to summarise their findings in a scientific journal-style report that incorporates graphical representations and statistical tests of their coral bleaching risk data. The research activity is cost-effective, repeatable, requires little specialised knowledge and addresses common programmatic learning outcomes that target scientific communication, quantitative reasoning and sustainability.     

Enhancing the learning of evolutionary anthropology skills by combining student‐active teaching with actual and virtual immersion of Master's students in fieldwork,laboratory practice,and dissemination

Higher education in evolutionary anthropology involves providing students with in‐depth knowledge of biological and cultural heritage sites and collections that are frequently inaccessible. Indeed, most sites, fossils, and archaeological remains can be visited or manipulated only rarely and solely by specialists with extensive experience. Owing to the development of 3D and medical imaging techniques, this fragile heritage is now more widely accessible, and in a dynamic way. However, exclusive adoption of virtual teaching and learning has a negative impact on student engagement and, naturally, on exchanges with instructors, and thus cannot be used without some reservations. In the ITAP (Immersion dans les Terrains de l’Anthropologie biologique et de la Préhistoire) project of the higher education STEP (Soutien à la Transformation et à l’Expérimentation Pédagogiques) transformation program at the University of Bordeaux, we combine student‐active teaching with Master''s students fully immersed in ongoing fieldwork, laboratory study, and dissemination of research results in order to develop more individually shaped learning curricula and to foster both professional and new interdisciplinary skills. Here, we present examples of experiments conducted in the ITAP project using both authentic and virtual collections of archaeological, experimental, and reference materials that help to break down the barriers between research activities and higher education, as well as providing a more general appraisal of the appropriate use of virtual tools in higher education by combining them with real‐life situations.     

Not Looking a Gift Horse in the Mouth: Exploring the Merits of a Student–Teacher–Scientist Partnership

One major emphasis of reform initiatives in science education is the importance of extended inquiry experiences for students through authentic collaborations with scientists. As such, unique partnerships have started to emerge between science and education in an ongoing effort to capture the interest and imaginations of students as they make sense of the world around them. One such partnership is called the student–teacher–scientist partnership, in which teachers and their students participate in and contribute to the research of scientists. This article explores a partnership between a 10th-grade biology teacher, her students, and practicing scientists who collaborated in the design, implementation and evaluation of a horse evolution unit. The primary goal of the collaborative activity was to involve teachers and students in a process of conceptual change as a means of eliminating common misconceptions implicit in horse evolution displays in museums in various parts of the country. The evidence-based lessons developed enhanced students’ understanding of concepts in macroevolution but also connected the science classroom with a community of scientists whose personalization of the horse evolution unit situated biological concepts and the learning experience within the context of real-world issues.     

Teacher candidates in the garden

Recent science education reform has led to an increased emphasis on engaging students in inquiry and science practices rather than having them simply memorize scientific facts. However, many teachers of elementary science may themselves have had more traditional science learning experiences, and may therefore be unsure about inquiry-based teaching methods. One way to enhance preservice teachers' comfort with and desire to teach science using a hands-on approach might be to engage them in science learning experiences alongside children during their educator preparation program. The purpose of this article is to share how one faculty member and a cooperating teacher from a partner school involve teacher candidates in working with children in the school's garden, allowing them to personally experience inquiry while witnessing firsthand the potential benefits to children of authentic science learning through garden based activities.     

Creating Science Picture Books for an Authentic Audience

This article presents an authentic writing opportunity to help ninth-grade students use the writing process in a science classroom to write and illustrate picture books for fourth-grade students to demonstrate and share their understanding of a biology unit on cells. By creating a picture book, students experience the writing process, understand how to share their learning with an authentic audience, and create an artifact that demonstrates their understanding of content knowledge.     

Perspectives on facilitating dynamic ecology courses online using active learning

As education methodology has grown to incorporate online learning, disciplines with a field component, like ecology, may find themselves sidelined in this transition. In response to challenges posed by moving classes online, previous studies have assessed whether an online environment can be effective for student learning. This work has found that active learning structures, which maximize information processing and require critical thinking, best support student learning. All too commonly, online and active learning are perceived as mutually exclusive. We argue the success of online learning requires facilitating active learning in online spaces. To highlight this intersection in practice, we use a case study of an online, active, and synchronous ecology and conservation biology course from the College of Natural Sciences at Minerva Schools at KGI. We use our perspectives as curriculum designers, instructors, and students of this course to offer recommendations for creating active online ecology courses. Key components to effective course design and implementation are as follows: facilitating critical “thinking like a scientist”, integrating open‐ended assignments into class discussion, and creating active in‐class dialogues by minimizing lecturing. Based on our experience, we suggest that by employing active learning strategies, the future of ecology in higher education is not inhibited, but in fact supported, by opportunities for learning online.     

An at‐home laboratory in plant biology designed to engage students in the process of science

The COVID‐19 pandemic prompted a transition to remote delivery of courses that lack immersive hands‐on research experiences for undergraduate science students, resulting in a scientific research skills gap. In this report, we present an option for an inclusive and authentic, hands‐on research experience that all students can perform off‐campus. Biology students in a semester‐long (13 weeks) sophomore plant physiology course participated in an at‐home laboratory designed to study the impacts of nitrogen addition on growth rates and root nodulation by wild nitrogen‐fixing Rhizobia in Pisum sativum (Pea) plants. This undergraduate research experience, piloted in the fall semester of 2020 in a class with 90 students, was created to help participants learn and practice scientific research skills during the COVID‐19 pandemic. Specifically, the learning outcomes associated with this at‐home research experience were: (1) generate a testable hypothesis, (2) design an experiment to test the hypothesis, (3) explain the importance of biological replication, (4) perform meaningful statistical analyses using R, and (5) compose a research paper to effectively communicate findings to a general biology audience. Students were provided with an at‐home laboratory kit containing the required materials and reagents, which were chosen to be accessible and affordable in case students were unable to access our laboratory kit. Students were guided through all aspects of research, including hypothesis generation, data collection, and data analysis, with video tutorials and live virtual sessions. This at‐home laboratory provided students an opportunity to practice hands‐on research with the flexibility to collect and analyze their own data in a remote setting during the COVID‐19 pandemic. This, or similar laboratories, could also be used as part of distance learning biology courses.     

Video laboratories for the teaching and learning of professional ethics in exercise physiology curricula

Student researchers in physiology courses often interact with human subjects in classroom research but may be unfamiliar with the professional ethics of experimenter-subject interactions. This communication describes experiences related to an interactive video used in exercise science and general biology courses to help students become aware of, sensitive to, and comfortable with implementing professional ethics into their own thinking and behavior as researchers before entering the laboratory. The activity consisted of a filmed exercise physiology experiment complemented with interactive question sheets followed by small- and large-group discussion and culminating with individual student reflections. Student written responses from multiple courses indicated that students were able to 1) identify and consider the ethics of experimenter-subject interactions from the movie, 2) generalize broader ideas of professional ethics from those observations, and 3) consider their observations in terms of future experiments they would be conducting personally and how they should interact with human subjects. A majority of students indicated a positive reaction to the video and identified specific aspects they appreciated. It is hoped that this report will encourage other instructors to consider the use of interactive videos in the teaching and learning of professional ethics related to their courses.     

Lessons learned through listening to biology students during a transition to online learning in the wake of the COVID‐19 pandemic

During the Spring Semester of 2020, an outbreak of a novel coronavirus (SARS‐CoV‐2) and the illnesses it caused (COVID‐19) led to widespread cancelling of on‐campus instruction at colleges and universities in the United States and other countries around the world. Response to the pandemic in university settings included a rapid and unexpected shift to online learning for faculty and students. The transition to teaching and learning online posed many challenges, and the experiences of students during this crisis may inform future planning for distance learning experiences during the ongoing pandemic and beyond. Herein, we discuss the experiences of first‐ and second‐year university students enrolled in a biology seminar course as their classes migrated to online environments. Drawing on reported student experiences and prior research and resources, we discuss the ways we will adjust our own teaching for future iterations of the course while offering recommendations for instructors tasked with teaching in online environments.
