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

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

Honors 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 ...

The Impacts Of Family Stem Events For Young Children On Parents' Perceptions In A Rural Remote School, Cheyenne Jeffers Aug 2019

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

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

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 Aug 2019

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

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

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

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

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 21st 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 for upper elementary students. This research action utilized a qualitative approach and was conducted using a combination of student interviews, assessments, and student self-reflections, and instructor observation notes ...


Hands-On, Guided Inquiry Science Investigation And Science Vocabulary Acquisition In A Rural Elementary School, Jennifer Mulder Aug 2019

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

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

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 ...


Traffic Noise And Sexual Selection: Studies Of Anthropogenic Impact On Bird Songs And Undergraduate Student Reasoning Of Evolutionary Mechanisms, Sarah Spier Aug 2019

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

Dissertations & Theses in Natural Resources

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 ...

Why Domain-Specific Science Knowledge Matters In Teacher Certification: Focusing On Evidence For Effective Science Teaching., Elizabeth B. Lewis, Lyrica Lucas, Amy Tankersley, Elizabeth Hasseler

Faculty Publications: Department of Teaching, Learning and Teacher Education

The landscape of teacher preparation is complex. From a research perspective, how to prepare teachers presents as a multilevel, multivariable puzzle. For decades, federal and state policymakers, educational researchers, and administrators, along with teacher education institutions, school districts, and other stakeholders have tried to determine and measure the key malleable factors that result in effective teaching (NRC, 2010).

Periodically, state departments of education review secondary science teaching endorsement policy guidelines. As revisions occur, teacher educators in higher education and district administrators need to engage in a multidisciplinary discussion about:

1. the ways in which strong domain-specific science content knowledge contributes ...


Establishing Enhanced Learning Outcomes In Science For First Generational Undergraduate College Students, Marianna Burks Apr 2019

Establishing Enhanced Learning Outcomes In Science For First Generational Undergraduate College Students, Marianna Burks

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

First-generation students represent an increasing percentage of the demographic for college and university enrollment at both the undergraduate and graduate levels. Since 2001, results from the National Center for Education Statistics Longitudinal Study, indicates ‘higher percentages of first-generations college students attended public postsecondary institutions-76 vs. 72%’ (Redford & Hoyer, 2017). There is insufficient research, however, concerning how first-generation students’ needs are different, even unique, from those students who are second- generation and beyond attending college (National Center for Educational Statistics, 2017). Since this increase of students enrolling in post-secondary education, ‘understanding the needs of first-generation students is imperative more now than ...


Student Perceptions Of Reasons For Lecture And Active Learning, Calan Koch Mar 2019

Student Perceptions Of Reasons For Lecture And Active Learning, Calan Koch

Honors Theses, University of Nebraska-Lincoln

With perceived student resistance to active learning in the classroom, instructors are hesitant to implement such methods into their classroom structure despite how effective they may be. This research seeks to understand student perceptions related to the transition to higher prevalence of active learning techniques. We aimed to find answers to how students perceive the ideal classroom to be structured, what reasons they perceive for lecture and active learning components, and possible explanations to concerns of groupwork during class time. We analyzed 64 interviews with undergraduate biology students at the University of Nebraska- Lincoln, developed coding rubrics from commonly found ...

How Do Teachers Use Comics To Promote Engagement, Equity, And Diversity In Science Classrooms?, Camilla Matuk, Talia Hurwich, Amy Spiegel, Judy Diamond Jan 2019

How Do Teachers Use Comics To Promote Engagement, Equity, And Diversity In Science Classrooms?, Camilla Matuk, Talia Hurwich, Amy Spiegel, Judy Diamond

World of Viruses

Equitable learning opportunities are critical to the goals of science education. However, major curriculum standards are vague on how to achieve equity goals, and educators must often develop their own resources and strategies to achieve equity goals. This study examines how educators used a comic book series designed to interest youth in virology as a way to make science more broadly appealing to their diverse students. We begin with the notion of Pedagogical Design Capacity, which describes a dynamic relationship between teachers and their tools and the ability for teachers to perceive and leverage affordances of artifacts as tools in ...

Student Understanding Of Dna Structure–Function Relationships Improves From Using 3d Learning Modules With Dynamic 3d Printed Models, Michelle E. Howell, Christine S. Booth, Sharmin M. Sikich, Tomáš Helikar, Rebecca Roston, Brain A. Couch, Karin Van Dijk

Biochemistry -- Faculty Publications

Understanding the relationship between molecular structure and function represents an important goal of undergraduate life sciences. Although evidence suggests that handling physical models supports gains in student understanding of structure–function relationships, such models have not been widely implemented in biochemistry classrooms. Three-dimensional (3D) printing represents an emerging cost-effective means of producing molecular models to help students investigate structure–function concepts. We developed three interactive learning modules with dynamic 3D printed models to help biochemistry students visualize biomolecular structures and address particular misconceptions. These modules targeted specific learning objectives related to DNA and RNA structure, transcription factor-DNA interactions, and DNA ...
