Posters As An Effective Assessment Tool For A Capstone Course, David Gosselin, Doug Golick

Department of Entomology: Faculty Publications

A rubric was developed to assess student posters as a mechanism to evaluate learning outcomes for a senior capstone course. The analytic rubric allows for the efficient and systematic collection of data from posters by students who worked across a variety of disciplines including the physical, biological, Earth sciences, social science, and the humanities. The rubric effectively addressed a fundamental assumption and requirement put forth during rubric development, that is, it needs to be relatively easy to use without training while at the same time producing consistent results across evaluators. The overall Chronbach’s alpha of 0.80 across semesters indicates acceptable …

Multiple True-False Questions Reveal More Thoroughly The Complexity Of Student Thinking Than Multiple-Choice Questions: A Bayesian Item Response Model Comparison, Chad Brassil, Brian A. Couch

School of Biological Sciences: Faculty Publications

Background: Within undergraduate science courses, instructors often assess student thinking using closed-ended question formats, such as multiple-choice (MC) and multiple-true-false (MTF), where students provide answers with respect to predetermined response options. While MC and MTF questions both consist of a question stem followed by a series of options, MC questions require students to select just one answer, whereas MTF questions enable students to evaluate each option as either true or false. We employed an experimental design in which identical questions were posed to students in either format and used Bayesian item response modeling to understand how responses in each …

Innovative Teaching Knowledge Stays With Users, A. Kelly Lane, Jacob D. Mcalpin, Brittnee Earl, Stephanie Feola, Jennifer E. Lewis, Karl Mertens, Susan E. Shadle, John Svoretz, John P. Ziker, Brian A. Couch, Luanna B. Prevost, Marilyne Stains

School of Biological Sciences: Faculty Publications

Programs seeking to transform undergraduate science, technology, engineering, and mathematics courses often strive for participating faculty to share their knowledge of innovative teaching practices with other faculty in their home departments. Here, we provide interview, survey, and social network analyses revealing that faculty who use innovative teaching practices preferentially talk to each other, suggesting that greater steps are needed for information about innovative practices to reach faculty more broadly.

Benefits Of A College Stem Faculty Development Initiative: Instructors Report Increased And Sustained Implementation Of Research-Based Instructional Strategies, Mary F. Durham, Oriana R. Aragón, Meghan E. Bathgate, Aiyanan Bobrownicki, Andrew J. Cavanagh, Xinnian Chen, William M. Trochim, Jonathan K. Waterhouse, Maek J. Graham, Brian A. Couch

School of Biological Sciences: Faculty Publications

The Summer Institutes on Scientific Teaching (SI) is a faculty development workshop in which science, technology, engineering, and mathematics (STEM) instructors, particularly from biology, are trained in the Scientific Teaching (ST) pedagogy. While participants have generally reported positive experiences, we aimed to assess how the SI affected participants’ teaching practices. Building on a previously developed taxonomy of ST practices, we surveyed SI participants from the 2004–2014 SI classes regarding specific ST practices. Participants’ self-reported use and implementation of ST practices increased immediately after SI attendance as well as over a longer time frame, suggesting that implementation persisted and even increased …

Examining The Role Of Spatial Skills And Mathematics Motivation On Middle School Mathematics Achievement, Kinnari Atit, Jason R. Power, Norma Veurink, David H. Uttal, Sheryl Sorby, Grace Panther, Camille Msall, Logan Fiorella, Martha Carr

Department of Civil and Environmental Engineering: Faculty Publications

Background: Spatial skills and mathematical ability have been repeatedly identified as critical for achievement in Science, Technology, Engineering, and Mathematics (STEM). Previous studies have identified correlations between spatial skills and mathematical achievement; however, questions remain regarding improvements in non-spatial areas associated with STEM achievement. The current study examined whether competency in spatial skills could be related to individuals’ motivation for mathematics. Measures of spatial skills and mathematics motivation were completed by 1056 seventh grade students.

Results: Using hierarchical linear modeling, spatial skills and math motivation were examined relative to students’ performance on a state standardized mathematics subtest. Results indicate that …

The Impact Of Active Learning In A Speech-Language Pathology Swallowing And Dysphagia Course, Rebecca H. Affoo, Justin L. Bruner, Angela M. Dietsch, Ciara Nellenbach, Theresa M. Jones, Mark E. Lehman

Department of Special Education and Communication Disorders: Faculty Publications

The signature pedagogy in Speech-Language Pathology (SLP) higher education programs has been criticized for its instructor-centric lecture format and emphasis on the lower tiers of Bloom’s taxonomy (simply memorizing knowledge) at the expense of helping students develop the clinical problem-solving skills required for a lifetime of practice and learning. The purpose of this study was to examine the responses of a cohort of graduate speech-language pathology students to an active learning-oriented swallowing and dysphagia course design. A potential relationship between student perceptions of the active learning pedagogy and academic performance was also explored. The results suggest that active learning positively …

Parent Involvement And Its Influence On Children’S Stem Learning: A Review Of The Research, Julie Thomas, Juliana Utley, Soo-Young Hong, Hunkar Korkmaz, Gwen Nugent

Department of Child, Youth, and Family Studies: Faculty Publications

A growing understanding that parents and teachers can effectively collaborate to help children succeed in school has led worldwide policymakers and school leaders to begin deliberate actions to increase parents’ participation in school life. For example, the Chilean Education Minister recently encouraged contracts between parents, schools, and the state to increase parental involvement. The Australian government has formed a Research Alliance for Children and Youth to develop and promote understanding of parent involvement (i.e., what it is, why it matters, how it influences learning) and to build evidence about what works. From a sociological perspective, a school’s organizational boundaries are …

A Mixed-Methods Study Of Entomology Incorporation In U.S. Secondary Science Instruction, Erin M. Ingram

Department of Entomology: Dissertations, Theses, and Student Research

To encourage understanding and appreciation of insects, entomology education advocates have supported and encouraged K-12 teachers to integrate insects and insect-related content into formal science instruction. However, research examining how and why science teachers incorporate entomology into secondary science courses is limited.

A sequential explanatory mixed-methods research study was conducted to address this gap. The study was conducted in two phases. During the first phase, quantitative survey research was conducted with a representative sample of 254 U.S. secondary life science teachers. During the subsequent qualitative phase, follow-up interviews were conducted with a purposeful sample of 18 survey participants and an …

“What Will I Experience In My College Stem Courses?” An Investigation Of Student Predictions About Instructional Practices In Introductory Courses, Clara L. Meaders, Emma S. Toth, A. K. Lane, J. Kenny Shuman, Brian A. Couch, Marilyne Stains, Mackenzie R. Stetzer, Erin Vinson, Michelle K. Smith

School of Biological Sciences: Faculty Publications

The instructional practices used in introductory college courses often differ dramatically from those used in high school courses, and dissatisfaction with these practices is cited by students as a prominent reason for leaving science, technology, engineering, and mathematics (STEM) majors. To better characterize the transition to college course work, we investigated the extent to which incoming expectations of course activities differ based on student demographic characteristics, as well as how these expectations align with what students will experience. We surveyed more than 1500 undergraduate students in large introductory STEM courses at three research-intensive institutions during the first week of classes …

Stem Opportunities - High School 2019, Huey-Xian Kelly Wong, Madeleine Rauhauser, Annie Morgan Nelson

Honors Program: Expanded Learning Clubs

This publication details the lesson plan for the “Opportunities in STEM” club for the summer of 2019. This club began out of a desire to educate high school students about the opportunities and careers available in the science, technology, engineering, and mathematics fields. Often, students feel that the prospect of entering a STEM field is daunting and out of their grasp. What it means to be a scientist is often unclear, and students never consider opportunities out of the fear of the unknown, particularly when science is associated with complexity and difficulty. This lesson plan integrates experiments with a wealth …

Investigating How Faculty Social Networks And Peer Influence Relate To Knowledge And Use Of Evidence-Based Teaching Practices, A. K. Lane, John Skvoretz, J. P. Ziker, Brian A. Couch, B. Earl, J. E. Lewis, J. D. Mcalpin, L. B. Prevost, S. E. Shadle, Marilyn Stains

School of Biological Sciences: Faculty Publications

Background: Calls for science education reform have been made for decades in the USA. The recent call to produce one million new science, technology, engineering, and math (STEM) graduates over 10 years highlights the need to employ evidence-based instructional practices (EBIPs) in undergraduate STEM classes to create engaging and effective learning environments. EBIPs are teaching strategies that have been empirically demonstrated to positively impact student learning, attitudes, and achievement in STEM disciplines. However, the mechanisms and processes by which faculty learn about and choose to implement EBIPs remain unclear. To explore this problem area, we used social network analysis …

Traffic Noise And Sexual Selection: Studies Of Anthropogenic Impact On Bird Songs And Undergraduate Student Reasoning Of Evolutionary Mechanisms, Sarah Spier

School of Natural Resources: Dissertations, Theses, and Student Research

Humans have transformed much of the natural landscape and are continuing to do so at an accelerated rate, compromising natural areas that serve as important habitat for many species. Roads impact much of the environment as they fragment habitat and introduce traffic noise into the acoustic environment, deferentially affecting wildlife in roadside habitat. I explored how traffic noise affects the detection of birds based on whether their vocalizations were masked by traffic noise. Masked species detection was not affected by an increase in traffic noise amplitude, while there was a negative effect of traffic noise amplitude on unmasked species detection, …

Hands-On, Guided Inquiry Science Investigation And Science Vocabulary Acquisition In A Rural Elementary School, Jennifer Mulder

Department of Teaching, Learning, and Teacher Education: Theses and Other Student Research

Much research has been done to show how inquiry science instruction and inquiry student investigation provide students with hands-on experiences to effectively learn science content in the classroom. Additionally, many methods to efficaciously teach students vocabulary has been thoroughly investigated. However, not much research has been done to study what effect hands-on, guided inquiry science investigation has on student content vocabulary acquisition. Within one rural classroom, fourth graders engaged in hands-on, guided inquiry investigation, and then vocabulary words were explicitly taught and discussed. After that, students practiced the vocabulary words in a variety of ways in pairs and as a …

The Impacts Of Family Stem Events For Young Children On Parents' Perceptions In A Rural Remote School, Cheyenne Jeffers

Department of Teaching, Learning, and Teacher Education: Theses and Other Student Research

STEM education is an interdisciplinary approach to creating learning experiences, preparing the children of today to become the workforce and global citizens of a digital tomorrow. Young children are natural explorers of their world, participating in STEM learning through real world experiences. Public and parental misconceptions are hurdles to implementing STEM learning with young children. Many believe young children are not capable of participating in STEM learning and should be taught foundational skills first. On the contrary, STEM learning should be a priority in the educational environment of young children, most beneficially combining efforts at home as well as at …

Improving Kindergartener’S Initiative To Problem Solve Through Integrated Stem, Jessica Walston

Department of Teaching, Learning, and Teacher Education: Theses and Other Student Research

Many teachers are familiar with students who are scared to try to solve a problem and instead look to adults for specific answers. Students need to be prepared to solve problems independently and collaboratively. One of the necessary skills to solve a problem is to first try, or take initiative. The purpose of this action research was to identify Kindergarten students’ initial initiative to problem solve by formal evaluation of student learning-related skills, taken from the Cooper-Farran Behavioral Rating Scale (1991). In this study, students were provided opportunities to take the initiative to problem solve through a series of integrated …

Strategies That Promote Elementary Student Stem Engagement, Jennifer Bauer

Department of Teaching, Learning, and Teacher Education: Theses and Other Student Research

Collaboration, creativity, persistence, and critical thinking are all skills encompassed when integrating STEM into today’s classrooms. Empowering students in STEM related areas is essential for students’ future success in the 21^st century and educators must prepare citizens for these types of creative skills (Cook & Bush, 2018). Integrating STEM disciplines through project-based learning and providing real-world situations to solve problems enhances student engagement and achievement in STEM concepts (Cook & Bush, 2018; Hall & Miro, 2016). The topic defined in this research plan focuses on instructional strategies that make STEM more meaningful to science curriculum, as well as engaging …

Meeting The Vision Of The Ngss: Critical Factors Of Effective Science Teaching (Poster), Elizabeth B. Lewis, Lyrica L. Lucas, Amy Tankersley, Elizabeth Hasseler, Brandon Helding

Department of Teaching, Learning, and Teacher Education: Presentations

With new national science education standards, we must understand how to prepare science teachers capable of advancing reform initiatives. In a 3-year longitudinal study we adopted a multi-method approach to investigate beginning science teachers’ instructional practices. We analyzed transcripts, observed science lessons, and documented weeks of lessons. Using this large dataset we posed research questions about the use of NGSS scientific practices in teachers’ science lessons (Project #1) and classroom diversity as it relates to teachers’ use of inquiry (Project #2). In order to expand our coding capability of science teaching data for use in our structural equation modelling efforts …

Comparing Nebraskan And Finnish Education Policy And Its Impacts On Mathematics Teaching, Elizabeth Tyler

Honors Program: Senior Projects (Public)

For two decades, Finland has been in the education spotlight as they consistently receive high international exam scores while spending less money, less time teaching, and putting students through fewer hours of school. This study aims to investigate the related policy that may help explain these seemingly paradoxical findings in the education sector. More specifically, this study examines how related policy impacts math teachers in their day to day work. This research includes an extensive literature review that explores several facets of the education system in both Nebraska and Finland in order to better understand existing policies. This background is …

Workforce Development Through Online Experiential Learning For Stem Education, Arefeh Mohammadi, Kevin Grosskopf, John Killingsworth

Durham School of Architectural Engineering and Construction: Faculty Publications

The U.S. workforce is increasingly comprised of older adults, women, and minorities who lack basic skills and are unable to acquire these skills through traditional educational and training programs. New approaches are needed to provide effective training to the adult learner and flexible support for nontraditional students who must balance work-life demands with limited educational opportunities. Contextualized teaching and learning (CTL) is a form of experiential learning that blends both basic skills and occupational training together in environments that allow students to relate subject matter to real-world situations. Virtual CTL environments can be created to better engage students, provide immediate …
