Launch-Explore-Summarize In High School Calculus, Nate Mattis
Launch-Explore-Summarize In High School Calculus, Nate Mattis
Honors Theses
Current research on high school calculus instruction indicates that students often possess a procedural knowledge of differentiation and integration as opposed to a conceptual knowledge (Orton, 1983; Ferrini-Mundy & Graham, 1994). Given the prominence of traditional lecture and textbook-based calculus classes in the United States, students are not always given the opportunity to expand their conceptual knowledge of essential calculus concepts. This project introduces calculus students to a more active and communal method of teaching: Launch-Explore-Summarize (LES) (CMP, n.d.). This methodology places students at the center of their learning and emphasizes inquiry-based thinking during a class. Specifically, two LES lessons …

Evaluation Of The Influence Of Wording Changes And Course Type On Motivation Instrument Functioning In Chemistry, Regis Komperda, Kathryn N. Hosbein, Jack Barbera
Chemistry Faculty Publications and Presentations
Increased understanding of the importance of the affective domain in chemistry education research has led to the development and adaptation of instruments to measure chemistry-specific affective traits, including motivation. Many of these instruments are adapted from other fields by using the word ‘chemistry’ in place of other disciplines or more general ‘science’ wording. Psychometric evidence is then provided for the functioning of the new adapted instrument. When an instrument is adapted from general language to specific (e.g. replacing ‘science’ with ‘chemistry’), an opportunity exists to compare the functioning of the original instrument in the same context as the adapted instrument. …

Evaluation Of The Redesign Of A Stem Gatekeeper Course, General Chemistry I, Incorporating Active-Learning Strategies And Implementation Of A Student-Choice Model, Travis Rae Mcdowell
Doctoral Dissertations
"The first courses freshman university students typically enroll in are the introductory science and math, courses that bridge from and build upon their prior educational experiences. These introductory courses often have large enrollment lectures coupled with supplemental sessions to teach using traditional educational practices, which may operate counter to the attitudes and culture of the students who take them. To address this, the general chemistry faculty through collaboration with a team of educational specialists initiated a redesign of the general chemistry course, which primarily serves first-year undergraduates. The redesign efforts included changes such as reducing lecture time and placing emphasis …
Precise Energy Efficient Scheduling Of Mixed-Criticality Tasks & Sustainable Mixed-Criticality Scheduling, Sai Sruti
Masters Theses
"In this thesis, the imprecise mixed-criticality model (IMC) is extended to precise scheduling of tasks, and integrated with the dynamic voltage and frequency scaling (DVFS) technique to enable energy minimization. The challenge in precise scheduling of MC systems is to simultaneously guarantee the timing correctness for all tasks, hi and lo, under both pessimistic and optimistic (less pessimistic) assumptions. To the best of knowledge this is the first work to address the integration of DVFS energy conserving techniques with precise scheduling of lo-tasks of the MC model.
In this thesis, the utilization based schedulability tests and sufficient conditions for such …

Gender Fairness Within The Force Concept Inventory, Adrienne Traxler, Rachel Henderson, John Stewart, Gay Stewart, Alexis Papak, Rebecca Lindell
Faculty & Staff Scholarship
Research on the test structure of the Force Concept Inventory (FCI) has largely ignored gender, and research on FCI gender effects (often reported as “gender gaps”) has seldom interrogated the structure of the test. These rarely crossed streams of research leave open the possibility that the FCI may not be structurally valid across genders, particularly since many reported results come from calculus-based courses where 75% or more of the students are men. We examine the FCI considering both psychometrics and gender disaggregation (while acknowledging this as a binary simplification), and find several problematic questions whose removal decreases the apparent gender …

Can Addressing Language Skills For Fifth Grade Ells In A Multiplication Curriculum Help Address The Achievement Gap In Math? A Multiplication Workbook For Big Kids, Michelle Douglas
Master's Projects and Capstones
Currently, the state of California has 1,332,405 students from grades k-12 who speak a language other than English at home (Caledfacts, 2016). When I started my first year teaching fifth grade with 95% of my students being English language learners (ELLs), I was surprised to see an achievement gap of two to three years in my student’s reading and math skills. I found that my student’s developmental language and math skills contributed to a lack of engagement during math time. Upon further research, I found that these three factors play a role in the wide achievement gaps between ELLs and …

Improving The Problem With Problem Solving, Cole Thibert
Essential Studies UNDergraduate Showcase
As a prospective math educator who will be teaching in the near future, I was concerned with the idea of preparing my future students for college math courses. I decided to research the effects of teaching students how to appropriately use problem solving strategies in math. My research led me towards looking at the benefits of students becoming better problem solvers and how teachers can implement problem solving into their daily lessons.
When this implementation is successful, students can become more independent with their learning, they are able to work and persevere through challenging problems, and they have a greater …

Farlie-Gumbel-Morgenstern Family: Equivalence Of Uncorrelation And Independence, G. Barmalzan, F. Vali
Applications and Applied Mathematics: An International Journal (AAM)
Considering the characteristics of the bivariate normal distribution, in which uncorrelation of two random variables is equivalent to their independence, it is interesting to verify this problem in other distributions. In other words, whether the multivariate normal distribution is the only distribution in which uncorrelation is equivalent to independence. In this paper, we answer to this question and establish generalized Farlie-Gumbel-Morgenstern (FGM) family is another family of distributions under which uncorrelation is equivalent to independence.

Ldentifying And Characterizing Cognitive Factors Significant To Practicing And Learning Meteorology, Peggy M. Mcneal
Ldentifying And Characterizing Cognitive Factors Significant To Practicing And Learning Meteorology, Peggy M. Mcneal
Dissertations
To see the world as a meteorologist, one must understand and interpret atmospheric processes through representations depicted on two-dimensional weather charts and maps that encode large amounts of spatial and numerical data. This is a cognitively demanding and spatially challenging task, especially for students with burgeoning levels of meteorology knowledge, who lack the expertise of practiced meteorologists that read such charts and maps with ease. With little prior work informing meteorology and meteorology education through a cognitive science lens, this study surveys the literature and follows models of discipline-based education and cognitive science research to identify the discrete intelligence factors …

Examining The Relationships Between Gender Role Congruity, Identity, And The Choice To Persist For Women In Undergraduate Physics Majors, Bronwen Bares Pelaez
FIU Electronic Theses and Dissertations
Persistent gender disparity limits the available contributors to advancing some science, technology, engineering, and math (STEM) fields. While higher education can be an influential time-point for ensuring adequate participation, many physics programs across the U.S. have few women in classroom or lab settings. Prior research indicates that these women face considerable barriers. For university students, faculty, and administration to appropriately address these issues, it is important to understand the experiences of women as they navigate male-dominated STEM fields.
This explanatory sequential mixed methods study explored undergraduate female physics majors’ experiences with their male-dominated academic and research spaces in the U.S. …

Apathy And Concern Over The Future Habitability Of Earth: An Introductory College Assignment Of Forecasting Co2 In The Earth’S Atmosphere, Benjamin J. Burger
Apathy And Concern Over The Future Habitability Of Earth: An Introductory College Assignment Of Forecasting Co2 In The Earth’S Atmosphere, Benjamin J. Burger
Journal on Empowering Teaching Excellence
Non-science, first year regional undergraduate students from rural Utah communities participated in an online introductory geology course and were asked to forecast the rise of CO2 in the Earth’s atmosphere. The majority of students predicted catastrophic rise to 5,000-ppm sometime over the next 3,100 years, resulting in an atmosphere nearly uninhabitable to human life. However, the level of concern the students exhibited in their answers was not directly proportional with their timing in their forecasted rise of CO2. This study showcases the importance of presenting students with actual data and using data to develop student forecasted models. …

2017 Academic High Altitude Conference
The goal of Bluegrass Community and Technical College’s (BCTC) Eclipse Outreach Ambassador Project was to get students across the Bluegrass excited and educated about the 2017 total solar eclipse. Several years ago the BalloonSat Project was started to provide hands-on earth and atmospheric science experiences to BCTC students. In linking the two initiatives, we allowed BCTC BalloonSat team members to continue learning to design, build, test, fly and retrieve balloon-borne payloads while using a novel method by which to engage local elementary and middle school students in learning more about and anticipating the upcoming eclipse. Eclipse practice flights carried payloads …

Experiences With Scala Across The College-Level Curriculum, Konstantin Läufer, George K. Thiruvathukal, Mark C. Lewis
Konstantin Läufer
Various hybrid-functional languages, designed to balance compile-time error detection, conciseness, and performance, have emerged. Scala, e.g., is interoperable with Java and has become an early leader in adoption, especially in the start-up and open-source spaces. As educators, we have recognized Scala’s value as a teaching language across the CS curriculum. In CS1, the read-eval-print loop and simple, uniform syntax aid programming in the small. In CS2, higher-order methods allow concise, efficient manipulation of collections. In a programming languages course, advanced constructs facilitate the separation of concerns, program representation and interpretation, and concurrent programming. In advanced applied courses, language mechanisms and …
