An Interpretive Plan Guide For Wilderness Park In Lincoln, Nebraska, Rachel J. Ward
An Interpretive Plan Guide For Wilderness Park In Lincoln, Nebraska, Rachel J. Ward
Community and Regional Planning Program: Professional Projects
Wilderness Park, located in Lancaster County, Nebraska, is a public park of unique ecological and historical value to the city of Lincoln and to the surrounding region. The natural and historical features of the park present an opportunity to communicate environmental and historical topics that are relevant on local, national, and global levels, as well as inspire a lively sense of pride in the community. The problem is that many topics relevant to Wilderness Park are not currently being interpreted at the park, and that there are relatively few interpretive resources available to park visitors.
The purpose of this project …
An Inventory Of Student Recollections Of Their Past Misconceptions As A Tool For Improved Classroom Astronomy Instruction, Andrej Favia
An Inventory Of Student Recollections Of Their Past Misconceptions As A Tool For Improved Classroom Astronomy Instruction, Andrej Favia
Electronic Theses and Dissertations
My Ph.D. research is about examining the persistence of 215 common misconceptions in astronomy. Each misconception is based on an often commonlyheld incorrect belief by college students taking introductory astronomy. At the University of Maine, the course is taught in alternating semesters by Prof. Neil F. Comins and Prof. David J. Batuski.
In this dissertation, I examine the persistence of common astronomy misconceptions by the administration of a retrospective survey. The survey is a new instrument in that it permits the student to indicate either endorsement or rejection of each misconception at various stages in the student’s life. I analyze …
The Experiences Of Women In Post Graduate Physics And Astronomy Programs: The Roles Of Support, Career Goals, And Gendered Experiences, Ramón S. Barthelemy
The Experiences Of Women In Post Graduate Physics And Astronomy Programs: The Roles Of Support, Career Goals, And Gendered Experiences, Ramón S. Barthelemy
Dissertations
In physics and astronomy the low representation of women is obvious at every stage of the educational pathway from undergraduate students to full professors. These low numbers perpetuate themselves by failing to create new mentors to foster the next generation of women. Women and men also have different experiences as they traverse into physics and astronomy careers. Women often experience chilly climates, discrimination, and challenges coordinating the demands of young families with their careers. In the literature exploring this topic, little focus is put on the experiences of women graduate students in physics and no focus is put on women …
Student Application Of The Fundamental Theorem Of Calculus With Graphical Representations In Mathematics And Physics, Rabindra R. Bajracharya
Student Application Of The Fundamental Theorem Of Calculus With Graphical Representations In Mathematics And Physics, Rabindra R. Bajracharya
Electronic Theses and Dissertations
One mathematical concept frequently applied in physics is the Fundamental Theorem of Calculus (FTC). Mathematics education research on student understanding of the FTC indicates student difficulties with the FTC. Similarly, a few studies in physics education have implicitly indicated student difficulties with various facets of the FTC, such as with the definite integral and the area under the curve representation, in physics contexts. There has been no research on how students apply the FTC in graphically-based physics questions.
This study investigated student understanding of the FTC and its application to graphically-based problems. Our interest spans several aspects of the FTC: …
Weaving Experimental Skills Throughout The Introductory Laboratory, John Zwart
Weaving Experimental Skills Throughout The Introductory Laboratory, John Zwart
Faculty Work Comprehensive List
The laboratory portion of an introductory course sequence can be used to meet a wide variety of goals ranging from illustrating phenomena studied in class, to building intuition about how the physical world works, to confronting the unexpected. Helping students develop experimental skills is a crucial goal that needs to be addressed in lab, especially in light of the fact that most introductory textbooks do not specifically address this topic. Important skills that students should learn in lab include how to analyze data, how to communicate results and the art of designing an experiment. This presentation will discuss how we …

The Magnetopause: Bringing Space Physics Into A Junior Lab, Jim Crumley, Ari Palczewski,, Stephen Kaster
The Magnetopause: Bringing Space Physics Into A Junior Lab, Jim Crumley, Ari Palczewski,, Stephen Kaster
MapCores Faculty Publications
Undergraduate students often have minimal exposure to many subfields
of physics which are active areas of research. Space physics
is an area that is particularly difficult to expose students to since
it builds off of another area that most undergraduates see little of,
plasma physics. The magnetopause is convenient entry point
into space physics, since it can be modeled as a pressure balance, which is
a concept familiar from introductory physics. We use the Earth's
magnetopause as the basis for a lab for junior physics majors. In
the lab students analyze results from a NASA MHD simulation and
data from …
The Discipline Of History And The “Modern Consensus In The Historiography Of Mathematics”, Michael N. Fried
The Discipline Of History And The “Modern Consensus In The Historiography Of Mathematics”, Michael N. Fried
Journal of Humanistic Mathematics
Teachers and students of mathematics often view history of mathematics as just mathematics as they know it, but in another form. This view is based on a misunderstanding of the nature of history of mathematics and the kind of knowledge it attempts to acquire. Unfortunately, it can also lead to a deep sense of disappointment with the history of mathematics itself, and, ultimately, a misunderstanding of the historical nature of mathematics. This kind of misunderstanding and the disappointment following from it--both raised to the level of resentment--run through the paper "A Critique of the Modern Consensus in the Historiography of …
How Do They Know It Is A Parallelogram? Analysing Geometric Discourse At Van Hiele Level 3, Sasha Wang, Margaret Kinzel
How Do They Know It Is A Parallelogram? Analysing Geometric Discourse At Van Hiele Level 3, Sasha Wang, Margaret Kinzel
Mathematics Faculty Publications and Presentations
In this article, we introduce Sfard's discursive framework and use it to investigate prospective teachers' geometric discourse in the context of quadrilaterals. In particular, we focus on describing and analysing two participants' use of mathematical words and substantiation routines related to parallelograms and their properties at van Hiele level 3 thinking. Our findings suggest that a single van Hiele level of thinking encompasses a range of complexity of reasoning and differences in discourse and thus a deeper investigation of students' mathematical thinking within assigned van Hiele levels is warranted.

Student's Objectives And Achievement Strategies For Laborataory Work, Taylor M. Owings
Open Access Theses
In this study, we look at students' objectives and strategies for completing their objectives for undergraduate labs. Students across two universities and three levels of chemistry were surveyed at the beginning of the semester in the fall of 2012 using an open ended survey to identify the goals students had for the course. The students responses were coded and used to create a survey that went out to the same courses at the end of the fall semester. Using data from the fall of 2012, the survey was modified and data was collected in the fall of 2013 at one …
Effective Geoscience Pedagogy At The Undergraduate Level, Kelsey Warden
Effective Geoscience Pedagogy At The Undergraduate Level, Kelsey Warden
Open Access Theses
This investigation used constructivist pedagogical methods within the framework of an introductory level undergraduate geoscience course to gauge both the changes in attitude and cognition of students. Pedagogy was modified in the laboratory setting, but maintained in the lecture setting and homework. Curriculum was also maintained in the lecture, but was changed in the laboratory to emphasize the large concepts and systems stressed in Earth Science Literacy Principles. Student understanding of these concepts and systems was strengthened by factual knowledge, but recall and memorization were not the goal of the laboratory instruction. The overall goal of the study was to …

Information systems students continue to struggle to successfully complete computer programming classes. Learning how to program is difficult, and failure and attrition rates in college level programming classes remain at an unacceptably high rate. Since many IS students take a programming course as part of their program of study, IS educators should better understand why IS students tend to achieve low success rates in programming courses and what can be done to improve success rates. Little research to date has addressed potential reasons for student failure in programming principles courses. Many educators simply assume that high failure rates are acceptable …
Investigating The Proposed Affordances And Limitations Of The Substance Metaphor For Energy, Lisa Goodhew
Investigating The Proposed Affordances And Limitations Of The Substance Metaphor For Energy, Lisa Goodhew
Honors Projects
This study explores the instructional advantages and disadvantages of representing energy as a material substance; this is done in the context of a computer simulation that illustrates processes of energy transfer and transformation. These affordances and limitations have been proposed in science education literature as extensions of the substance metaphor itself, but there is little empirical evidence to support them. This study is intended to provide preliminary empirical evidence for these affordances and limitations. We examine data from eight interviews conducted with students from Seattle Pacific University’s introductory physics classes as they used the simulation. We explore the hypotheses that …

I first walked through the doors of Morrill Hall on the main or City Campus of the University of Nebraska on a day late in August of 1962 and thought that I had entered paleontology heaven. Morrill Hall then housed the University of Nebraska State Museum (UNSM). most of the Geology Department, and some other parts of university units. I was a new graduate student hoping to pursue research in invertebrate paleontology in the Department of Geology and was on my way to see the department chairman for the first time. When I entered the building I walked through a …
Chemistry Graduate Teaching Assistants: A Comparison Of The Classroom Discourse Within Expository And Problem-Based Learning Laboratories, Kelley M. Current
Chemistry Graduate Teaching Assistants: A Comparison Of The Classroom Discourse Within Expository And Problem-Based Learning Laboratories, Kelley M. Current
Masters Theses
Graduate Teaching Assistants (GTAs) commonly function as instructors within undergraduate chemistry laboratories. This study sought to explore and describe GTA classroom discourse within two distinct instructional modes, using discourse analysis as the theoretical framework. Theclassroom discourse within a series of verification style labs was comparedto the classroom discourse produced within a set of Problem-Based Learning (PBL) labs. The results suggest three primary findings: (1) the apparent relationship between the instructional mode and form of GTA classroom discourse, (2) the patterns in classroom discourse observed within a given instructional mode repeat, irrespective of content, and (3) the classroom discourse observed within …

The Real-Time Instructor Observing Tool For Future Teachers, Cassandra Paul
Faculty Publications
Current educational research shows that students achieve higher learning gains in science classrooms when interactive techniques are used. As a result, we are seeing more high schools and institutions of higher education adopt interactive courses. Unfortunately, it's difficult for future teachers to envision interactive science courses because their experience as students has been dominated by traditional lecture. New educators need to know what interactive science classrooms look like, so that they can model this experience in their own classrooms. The Real-time Instructor Observing Tool (RIOT), a computer application that allows an observer to quickly categorize classroom interactions, can help with …

Students seem to struggle with transferring prior knowledge if the new problem they are given is in a different form from the way they learned the material. The process of transfer can be identified by four components: 1) recognizing the similarity between the old and new contexts; 2) identifying the potential of a certain skill or concept that has worked in the past, to give solutions to new problematic situations; 3) mental testing of the application of the potential solution; and 4) an attempt to apply the skill or concept to a new context (Georghiades 2000). These four components are …

Using A Spreadsheet To Solve The SchröDinger Equations For The Energies Of The Ground Electronic State And The Two Lowest Excited States Of H2, Yingbin Ge, Robert C. Rittenhouse, Jacob C. Buchanan, Benjamin Livingston
All Faculty Scholarship for the College of the Sciences
We have designed an exercise suitable for a lab or project in an undergraduate physical chemistry course that creates a Microsoft Excel spreadsheet to calculate the energy of the S0 ground electronic state and the S1 and T1 excited states of H2. The spreadsheet calculations circumvent the construction and diagonalization of the Fock matrix and thus can be accomplished by any undergraduate chemistry student with basic calculus skills. The wave functions of the S0, S1, and T1 states of H2 are constructed from the symmetry-adapted bonding and antibonding molecular …

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
In secondary math classrooms there has been a movement toward discovery and problem solving based instruction. This type of instruction requires teachers to teach on what is often considered a higher level of cognition and allows students to discover more ideas and concepts on their own as opposed to traditional lecture style. Teachers with well thought-out examples, questions, and activities provide students with tools to solve problems on their own requiring students to make mathematical discoveries and connections. These skills not only benefit students in their math class but are analytical skills students can use throughout their lives.

Calculator Usage In Secondary Level Classrooms: The Ongoing Debate, Nicole Plummer
Honors College Theses
With technology becoming more prevalent every day, it is imperative that students gain enough experience with different technological tools in order to be successful in the “real-world”. This thesis will discuss the debate and overall support for an increased usage of calculators as tools in the secondary level classroom. When the idea of calculators in the classroom first came to life, many educators were very apprehensive and quite hesitant of this change. Unfortunately, more than 40 years later, there is still hesitation for their usage; and rightfully so. While there are plenty of advantages of calculator use in the classroom, …

The research and development (R&D) processes influence the economic development of a company, because in an industry that is changing fast, firms must continually revise their projects and range of products. Therefore in order to determine the specific costs of research and development activity we have to highlight the efforts and effects of these activities and to calculate some indicators of economic efficiency. In the cost calculation process in R & D we have emphasized the identification of the components of cost and the duration of the R & D processes, as a component of the R&D cost, that is …
