A Collection Of Calculus Lesson Plans: Deriving The 'Why' Behind Derivatives, Kasey Brabec

Honors Theses

The traditional mathematics classroom is led with a focus on procedural understanding, with deep conceptual understanding considered to be unimportant or too difficult to teach within the allotted time. Both levels of understanding are important mathematical competencies, as it is rare for either of them to function well without accessibility to the other. The disparity between conceptual understanding and procedural understanding in the mathematics classroom is no larger than in courses like Calculus. This project is a collection of fifteen lesson plans constructed with an emphasis on conceptual understanding and the connectivity of Calculus. Each lesson plan’s overview contains the …

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 …

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, …

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

Honors Theses

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 …

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

Honors Theses

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 …

Evolution And Nature Of Science Instruction: A First-Person Account Of Changes In Evolution Instruction Throughout A Career, Lawrence C. Scharmann

Department of Teaching, Learning, and Teacher Education: Faculty Publications

In this article, I provide an analysis of my work (1985–present) with non-major biology students and science teacher candidates in developing strategies for teaching and enhancing learning with respect to evolutionary science. This first-person account describes changes in evolution instruction over the course of a career based on personal experiences, research-informed practices, and a critical collaboration with colleague Mike U. Smith. I assert four insights concerning the influence and efficacy of teaching nature of science (NOS) prior to the introduction of evolution within college courses for science non-majors and science teacher candidates. These insights are: (a) teach explicit NOS principles …

Reflections On Inquiry-Based Learning In A First-Year Algebra Classroom: Implications For Practitioners, Gregory P. Sand

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

This self-study examines the learning by the teacher and students in a first-year Algebra class in a medium sized Midwestern city. The author, a secondary mathematics teacher, overviews two problems of practice and outlines methodology used to study these problems within the standard curriculum of first-year Algebra taught using inquiry-based methodology. Three units of study, Inequalities, Exponents, and Parabolas are analyzed to identify the learning of students and the mathematical and pedagogical learning of the teacher. Emergent mathematical and pedagogical themes from the analysis chapters are discussed with implications for practice.

Assessing Student Comprehension In Introductory Biology: A Comparison Of Free-Response And Multiple-True/False Exam Formats, Macy A. Potts, Brian Couch, Joanna K. Hubbard

UCARE Research Products

Question format is an important consideration when designing instruments to gauge student comprehension. In many lecture-style courses, instructors must decide how to effectively test a large group of students. Two common types of question formats used for introductory biology exams are free-response (FR) and multiple-true/false (MTF). FR questions include a question prompt which students respond to with essay-style answers. Conversely, MTF questions include an opening question stem with accompanying statements to be marked as either true or false. The goal of this study was to determine the advantages and disadvantages of FR and MTF question formats for assessing student comprehension …

Effective Science Teachers’ Professional Development: A Multiple-Case Study Of District-Level Science Supervisors’ Perspectives, Chris J. Schaben

College of Education and Human Sciences: Dissertations, Theses, and Student Research

At its heart, science teachers’ professional development is about continual growth and improvement (Yager, 2005). Conducting research to understand what constitutes effective professional development is inherently complex (Hewson, 2007). The imperative to link research on professional development to student achievement (Fishman, Marx, Best, & Tal, 2003) increases complexity of research on the topic. These complexities require multiple research approaches and indicate that all stakeholders could provide insights to identify what constitutes effective professional development. District-level science supervisors’ voices are missing from the data on effective science teachers’ professional development and this provides a potential gap in the literature (Banilower, Heck, …

Changing Perceptions Of Science In Undergraduate Students: A Mixed Methods Case Study, Cindy S. Larson-Miller

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

The purpose of this bounded single-case study was to explore the understanding of the nature and process of science for undergraduate students at the University of Nebraska-Lincoln (UNL). The study investigated one professor’s methodology to explicitly teach undergraduate students about the nature and process of science, and documented their understanding and perception of science, both pre- and post-course.

Using a mixed method approach, data were collected to provide a better understanding of teaching the nature and process of science. Three main types of data were analyzed: the process of science (TPOS) assessment; survey questions, and the module curriculum.
