Session 3e: Teaching Using Un Sustainable Development Goals, Donald Dosch, Sarah O'Leary-Driscoll, Crystal Randall

Professional Learning Day

This session will focus on how we are using the UN Sustainable Development Goals as guideposts for curriculum development in several of our different science classes. Students will join us to present some of their varied academic work, and share the importance of these activities in their education. Part of our discussion will focus on scaffolding the learning so that students are able to perform successfully in these contextual and issues-based activities. We will also build in time for participant discussion on current issues and ideas for incorporating them effectively into their own teaching.

Eight-Legged Encounters—Arachnids, Volunteers, And Art Help To Bridge The Gap Between Informal And Formal Science Learning, Eileen Hebets, Melissa Welch-Lazoritz, Pawl Tisdale, Patricia Wonch Hill

Eileen Hebets Publications

Increased integration and synergy between formal and informal learning environments is proposed to provide multiple benefits to science learners. In an effort to better bridge these two learning contexts, we developed an educational model that employs the charismatic nature of arachnids to engage the public of all ages in science learning; learning that aligns with the Next Generation Science Standards (NGSS Disciplinary Core Ideas associated with Biodiversity and Evolution). We created, implemented, and evaluated a family-focused, interactive science event—Eight-Legged Encounters (ELE)—which encompasses more than twenty modular activities. Volunteers facilitated participant involvement at each activity station and original …

Student, Instructor, And Observer Agreement Regarding Frequencies Of Scientific Teaching Practices Using The Measurement Instrument For Scientific Teaching-Observable (Misto), Mary F. Durham, Jennifer Knight, Emily K. Bremers, Jameson D. Defreece, Alex R. Paine, Brian A. Couch

School of Biological Sciences: Faculty Publications

Background: The Scientific Teaching (ST) pedagogical framework encompasses many of the best practices recommended in the literature and highlighted in national reports. Understanding the growth and impact of ST requires instruments to accurately measure the extent to which practitioners implement ST in their courses. Researchers have typically relied on students, instructors, or observers to document course teaching practices, but it remains unclear whether and how these perspectives differ from each other. To address this issue, we modified our previously published instrument to generate the Measurement Instrument for Scientific Teaching-Observable (MISTO), which can be completed by students, instructors, and observers, and …

What Types Of Instructional Shifts Do Students Experience? Investigating Active Learning In Science, Technology, Engineering, And Math Classes Across Key Transition Points From Middle School To The University Level, Kenneth Akiha, Emilie Brigham, Brain A. Couch, Justin Lewin, Marilyne Stains, Mackenzie R. Stetzer, Erin L. Vinson, Michelle K. Smith

School of Biological Sciences: Faculty Publications

Despite the need for a strong Science, Technology, Engineering, and Math (STEM) workforce, there is a high attrition rate for students who intend to complete undergraduate majors in these disciplines. Students who leave STEM degree programs often cite uninspiring instruction in introductory courses, including traditional lecturing, as a reason. While undergraduate courses play a critical role in STEM retention, little is understood about the instructional transitions students encounter upon moving from secondary to post-secondary STEM courses. This study compares classroom observation data collected using the Classroom Observation Protocol for Undergraduate STEM from over 450 middle school, high school, introductory-level university, …

Ecoevo-Maps: An Ecology And Evolution Assessment For Introductory Through Advanced Undergraduates, Mindi M. Summers, Brian A. Couch, Jennifer K. Knight, Sara E. Brownell, Alison J. Crowe, Katharine Semsar, Christian D. Wright, Michelle K. Smith

School of Biological Sciences: Faculty Publications

A new assessment tool, Ecology and Evolution–Measuring Achievement and Progression in Science or EcoEvo-MAPS, measures student thinking in ecology and evolution during an undergraduate course of study. EcoEvo-MAPS targets foundational concepts in ecology and evolution and uses a novel approach that asks students to evaluate a series of predictions, conclusions, or interpretations as likely or unlikely to be true given a specific scenario. We collected evidence of validity and reliability for EcoEvo-MAPS through an iterative process of faculty review, student interviews, and analyses of assessment data from more than 3000 students at 34 associate’s-, bachelor’s-, master’s-, and doctoral-granting institutions. The …

Many Paths Toward Discovery: A Module For Teaching How Science Works, Rebecca M. Price, Kathryn E. Perez

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

Improving students' understanding of how science works requires explicit instruction. Here, we test the efficacy of a module based on two previously published activities (the "Cube Puzzle" and the case study "Asteroids and Dinosaurs") that teach how science works to college science majors. Students also use the How Science Works Flowchart from Understanding Science (http://undsci.berkeley. edu/) to reflect on these activities. To assess the efficacy of this module, we asked students to illustrate the process of science before and after the intervention. After the intervention, students' diagrams were significantly more complex and nonlinear. Students also incorporated more social aspects of …

A Teachable Unit On Soft Corals With Instructional Method Variances, Emily Breech

Honors Projects

The soft coral Sinularia flexibilis contains an aqueous alcohol extract that has shown antineoplastic activity against lymphocytic leukemia (Weinheimer and Matson, 1977). It also has other biological properties that work as antimicrobials, anti-inflammatory agents, and cytotoxicity activities (Kamel and Slattery, 2005). There is much research on the effects of flow rate on growth and morphology (Khalesi, Beeftink, & Wijffels, 2007) and the effects of light-dependency on growth rate (Khalesi, Beeftink, & Wijffels, 2009). The purpose of this student project was to further research on S. flexibilis, as well as incorporate that research into evaluating the effects of lecture-based teaching …

Examining The Understanding Of Inquiry-Based Learning And Teaching Among Undergraduate Teachers And Students, Maren Hudson

Electronic Theses and Dissertations

One of the main aims of inquiry is to engage students as active, not passive, participants in science. The purpose of this study is to describe science educators’ and students’ views about inquiry-based instruction in order to better understand and improve implementation of evidence-based teaching strategies. Inquiry-based techniques have been shown to improve student understanding of scientific concepts, yet, there continue to be challenges in implementing these techniques. This research project utilizes Q Methodology, a research method that captures both common and disparate measures of subjectivity, to identify commonalities and defining viewpoints about inquiry-based teaching and learning. Three significantly different …

Promoting Critical Thinking In General Biology Courses: The Case Of The White Widow Spider, Joseph S. Wilson

Journal on Empowering Teaching Excellence

It is generally accepted that critical thinking is an important and, likely, essential, component of success in college and beyond. Despite the unanimity, only a low percentage of students in the U.S. can demonstrate critical thinking proficiency on standardized exams. This phenomenon may result from instructors using a reductionist view of critical thinking and focusing on learning processes rather than on evaluation of intellectual resources. In general biology courses, I use a non-threatening, active-learning, group activities to promote critical thinking. For example, students are presented with an email from a member of the community and asked to formulate a response …

Walking As Ontological Shifter: Thoughts In The Key Of Life, Bibi (Silvina) Calderaro

Dissertations, Theses, and Capstone Projects

With walking as ontological shifter I pursue an alternative to the dominant modernist episteme that offers either/or onto-epistemologies of opposition and their reifying engagements. I propose this type of walking is an intentional turning towards a set of radical positions that, as integrative aesthetic and therapeutic practice, brings multiplicity and synchronicity to experience and being in an expanded sociality. This practice facilitates the conditions of possibility for recurring points of contact between the interiority perceived as ‘body’ and the exteriority perceived as ‘world.’ While making evident the self’s at once incoherence with it-self, it opens to a space beyond the …

Designing An Authentic Behavioral Research Experience In The Classroom Using Siamese Fighting Fish, Betta Splendens, Gianne Souza, Ronald M. Coleman

STAR Program Research Presentations

Recently there have been major shifts in biology education towards emphasizing the teaching of the scientific process to more closely reflect actual scientific practices. Authentic research experiences require the development of many higher order cognitive skills. Creating an authentic research experience that appropriately scaffolds the development of these complex skills while engaging individual student motivation remains challenging in classroom settings. Some common challenges include limited time available for working with large numbers of students, cramped working areas, and limited funding and materials resources. Using the Siamese Fighting Fish, Betta splendens, we have created an economically viable authentic animal behavioral …

Creating A Learning Community In The Sciences, Bart De Stasio, Beth De Stasio, Brian Piasecki

Diversity Conference 2017

Science is a collaborative discipline that is best learned through discussion, experimentation and group activity. But several groups of students—particularly students of color, first generation college students and some international students— are often marginalized in our classrooms, labs and are left out of study groups. Their voices aren’t heard, their points of view and interpretations aren’t always appreciated and the learning of these students is thwarted. To address these issues, we have been involved in forming and designing two groups that have been functioning for the past two years: LEDS (Lawrentians Enhancing Diversity in the Sciences) and BioCore, a supplementary …

How Do Former Undergraduate Mentors Evaluate Their Mentoring Experience 3-Years Post-Mentoring: A Phenomenological Study, Kari L. Nelson, Christine E. Cutucache

The Qualitative Report

This phenomenological study involves a unique, longitudinal assessment of the lived experiences of former undergraduate mentors (n=7) in light of their current experiences (i.e., career or advanced schooling). The objective of a phenomenological study is to engage in in-depth probing of a representative number of participants. Specifically, we followed up with graduates of the Nebraska STEM 4U (NE STEM 4U) intervention 3 years post-program, with the overall goal of describing the mentors’ experiences using the lens of their current experiences. This type of longitudinal perspective of mentoring is greatly lacking in the current literature. At the time of the interviews, …

Parts Of The Whole: Why I Teach This Subject This Way, Dorothy Wallace

Numeracy

The importance of mathematics to biology is illustrated by search data from Google Scholar. I argue that a pedagogical approach based on student research projects is likely to improve retention and foster critical thinking about mathematical modeling, as well as reinforce quantitative reasoning and the appreciation of calculus as a tool. The usual features of a course (e.g., the instructor, assessment, text, etc.) are shown to have very different purposes in a research-based course.

Effectiveness Of The Flipped Classroom Model In Anatomy And Physiology Laboratory Courses At A Hispanic Serving Institution, Gerardo Sanchez

Theses and Dissertations

A flipped laboratory model involves significant preparation by the students on lab material prior to entry to the laboratory. This allows laboratory time to be focused on active learning through experiments. The aim of this study was to observe changes in student performance through the transition from a traditional laboratory format, to a flipped format. The data showed that for both Anatomy and Physiology (I and II) laboratories a more normal distribution of grades was observed once labs were flipped and lecture grade averages increased. Chi square and analysis of variance tests showed grade changes to a statistically significant degree, …

How Question Types Reveal Student Thinking: An Experimental Comparison Of Multiple-True-False And Free-Response Formats, Joanna K. Hubbard, Macy A. Potts, Brian A. Couch

School of Biological Sciences: Faculty Publications

Assessments represent an important component of undergraduate courses because they affect how students interact with course content and gauge student achievement of course objectives. To make decisions on assessment design, instructors must understand the affordances and limitations of available question formats. Here, we use a crossover experimental design to identify differences in how multiple-true-false (MTF) and free-response (FR) exam questions reveal student thinking regarding specific conceptions. We report that correct response rates correlate across the two formats but that a higher percentage of students provide correct responses for MTF questions. We find that MTF questions reveal a high prevalence of …

Approaching Undergraduate Research With Students Who Are Deaf And Hard-Of-Hearing, Austin U. Gehret, Jessica W. Trussell, Lea V. Michel

Journal of Science Education for Students with Disabilities

An undergraduate research experience can provide a unique opportunity for students to learn and grow as scientists; when positive, this experience is often transformative and motivates students to pursue science, technology, engineering and mathematics (STEM) graduate degrees or careers. Conversely, negative research experiences can sour a student’s opinion of research, propagate misconceptions of graduate school, and lead to attrition from STEM fields. Negative research experiences can be equally devastating for faculty mentors and may result in reluctance to mentor future research students. Using a mentoring approach that has traditionally translated to positive research experiences for hearing students may not be …

Inclusive Teaching Strategies: An Evaluation Of Course Structure And Summative Assessment In Introductory Biology, Oluwaseun O. Agboola

Electronic Theses and Dissertations

Several active learning strategies have been used when increasing the structure of a course as increasing course structure has been known to improve student learning in introductory STEM courses. Much has been studied on the value of frequent formative assessment; however, few studies have evaluated the effective modes of delivering summative assessment. This study examines the use of summative assessment as an inclusive teaching practice to improve first generation college student success in introductory biology and also uses faculty surveys to find out how instructors structure their introductory biology course and why they are structured that way. Final exams were …

Implementation Of A Biology Summer Bridge Program For First-Year Biology Majors, Madelyn Aittama

Honors Theses

Students are entering higher education at an escalated rate, but many are unprepared for the rigorous coursework that lies ahead of them. As nationwide programs are continuously being implemented throughout high schools to better prepare students for college life, many students are still not equipped with the skills necessary to succeed in obtaining a bachelor’s degree. Many students feel discouraged and inadequate when they perform below their academic expectations, and for a large portion of students pursuing higher education, this results in discontinuing their education. While retention rates amongst STEM (science, technology, engineering and mathematics) students are particularly low, the …

Each To Their Own Cure: Faculty Who Teach Course-Based Undergraduate Research Experiences Report Why You Too Should Teach A Cure, Erin E. Shortlidge, Gita Bangera, Sara Brownell

Biology Faculty Publications and Presentations

Course-based undergraduate research experiences (CUREs) meet national recommendations for integrating research experiences into life science curricula. As such, CUREs have grown in popularity and many research studies have focused on student outcomes from CUREs. Institutional change literature highlights that understanding faculty is also key to new pedagogies succeeding. To begin to understand faculty perspectives on CUREs, we conducted semi-structured interviews with 61 faculty who teach CUREs regarding why they teach CUREs, what the outcomes are, and how they would discuss a CURE with a colleague. Using grounded theory, participant responses were coded and categorized as tangible or intangible, related to …

Rolling Circle Mutagenesis Of Gst-Mcherry To Understand Mutation, Gene Expression, And Regulation, Jessica Cole, Amanda Ferguson, Verónica A. Segarra, Susan Walsh

Biology Faculty Publications and Presentations

Undergraduates are often familiar with textbook examples of human mutations that affect coding regions and the subsequent disorders, but they may struggle with understanding the implications of mutations in the regulatory regions of genes. We have designed a laboratory sequence that will allow students to explore the effect random mutagenesis can have on protein function, expression, and ultimately phenotype. Students design and perform a safe and time-efficient random mutagenesis experiment using error-prone rolling circular amplification of a plasmid expressing the inducible fusion protein glutathione S-transferase (GST)-mCherry. Mutagenized and wild-type control plasmid DNA, respectively, are then purified and transformed into bacteria …

Taxonomy, Ecology, And Behavior Of The Kleptoplastic Sea Slug Elysia Papillosa, William Alan Gowacki

USF Tampa Graduate Theses and Dissertations

Sacoglossan sea slugs are one of the best known examples of specialist herbivores in the marine environment and can be found strongly associated with their algal hosts and food sources. Perhaps the most intriguing characteristic of many sacoglossans is their ability to sequester functional chloroplasts from their algal food sources in a process called kleptoplasty. Despite this, there continues to be issues regarding taxonomic identification of species. In turn, the ecological characteristics of many of these slugs, such as algal host and food source preference, as well as their behavioral aspects, have received little attention. A prime example of these …
