Teacher Perceptions On Changing Instructional Practices In Mathematics With The Implementation Of The Common Core State Standards, Esther M. Underwood

Dissertations, Masters Theses, Capstones, and Culminating Projects

As schools across the U.S. begin to implement Common Core State Standards in Mathematics (CCSSM), teachers must shift their instructional practices from a traditional emphasis on procedures and algorithms to a conceptually based model in which students engage more meaningfully with mathematical concepts. The purpose of this study is to examine participants’ perspectives about the influence of CCSSM on their instructional practices, and the challenges they face in effectively implementing these changes. The literature reveals the need for professional development, standards aligned materials, and ongoing support of teachers in order for them to make substantial changes to their instructional approach. …

Investigating The Impact Of Reflexive Practices On College Students In A Science Laboratory Course, Chandrani Mishra

Dissertations

Emphasis on professional practices to develop students’ professionalism is currently a major focus of higher education. Studies have shown the benefits of reflexive practices in classroom to facilitate the development of students’ professional attitude or identity in some fields. Reflexive practices involve students in self-reflection where he/she reflects on his/her own actions. Little investigation about the benefits of reflexive practices in the development of students’ scientific identity in a science class led to my investigation. Development of a scientific identity of students and their overall interest and motivation in science is deemed essential for retaining students in STEM fields.

An Optimal Reinsurance Contract From Insurer's And Reinsurer's Viewpoints, Ali P. Bazaz, Amir T. Payandeh Najafabadi

Applications and Applied Mathematics: An International Journal (AAM)

This article constructs two classes of appropriate reinsurance contracts from both an insurer’s and a reinsurer’s viewpoints. The first class, say C; has been constructed by minimizing the conditional tail expectation, say CTE, of an insurer’s random risk. Then an optimal reinsurance contract has been obtained by estimating the reinsurance’s random risk, using the Bayesian estimation method while the second class of reinsurance contracts, say C*; is obtained by minimizing a convex combination of the CTE of both the insurer’s and reinsurer’s random risks. These two approaches consider both the insurer’s and reinsurer’s viewpoints to establish an optimal reinsurance contract. …

Seir Model Of Seasonal Epidemic Diseases Using Ham, Nirmala P. Ratchagar, S. P. Subramanian

Applications and Applied Mathematics: An International Journal (AAM)

SEIR mathematical model of childhood diseases measles, chickenpox, mumps, rubella incorporate seasonal variation in contact rates due to the increased mixing during school terms compared to school holidays. Driven by seasonality these diseases are characterized by annual oscillations with variable contact rate which is a periodic function of time in years. Homotopy Analysis Method (HAM) is considered in this paper to obtain a semi analytic approximate solution of non-linear simultaneous differential equations. Mathematica is used to carry out the computations. Results established through graphs show the validity and potential of HAM for amplitude of variation greater than zero. Also, when …

On The Stability Of A Pexiderized Functional Equation In Intuitionistic Fuzzy Banach Spaces, Nabin C. Kayal, Pratap Mondal, T. K. Samanta

Applications and Applied Mathematics: An International Journal (AAM)

During the last few decades several researchers have been devoted to establishing stability of different kinds of functional equations, differential equations, functional differential equations, fractional differential equations, etc. under different sufficient conditions in different spaces like Banach spaces, Banach modules, fuzzy Banach spaces etc. In this paper, we remain confined in the discussion of stability of functional equations in intuitionistic fuzzy Banach spaces. Ulam was the first person who introduced an open question concerning the stability of a group homomorphism in an international conference. Thereafter several researchers have replied and are still replying to this open question in different contexts. …

On Calculation Of Failure Probability For Structures Designed Based On Magnitudes Of Historical Event, Farzad Noubary, Reza Noubary

Applications and Applied Mathematics: An International Journal (AAM)

During their operational life, structures may be subject to various types of live load caused by events such as earthquakes, high speed winds, etc. Given the design life of a structure, the probability for a specific live load to cause a failure depends on the magnitude of the load structure it is designed to withstand (designed load). In this article, methods are developed for calculation of the failure probability for structures designed to withstand loads comparable to historical loads at the site of interest.

Identities And Motives Of Naturalist Development Program Attendees And Their Relation To Professional Careers, Jennifer A. Mraz

Dissertations

In recent years, there has been much concern over the decline of biologists who actually identify themselves to be naturalists, which negatively impacts the field of conservation and the study of biology as a whole. This could result in a decrease in individuals who participate in naturalist-like activities, such as informal environmental education and environmental volunteerism. The purpose of my study was to determine what discourse identities were held by naturalist development program participants, how these discourse identities related to their volunteer motives in environmental settings, and how discourse identity related to professional careers. I defined identity through the lens …

Teacher Participation And Motivation Inprofessional Development, Krystal A. Hill

Theses and Dissertations

Although professional development is accepted as important for making educational improvements, some have been unsuccessful due to how the teachers choose to participate, and the lack of motivation in teachers to attend or implement the suggested changes. A case study of secondary mathematics teachers in a required professional development is used to look at teachers' motivation and participation during the professional development. This study compared mathematics teachers' motivation to attend with ways of participating in order to determine how these influence a teacher's intent to change. It was found that certain aspects of motivation and participation does influence a teacher's …

Crystallographic Education In The 21st Century, Saulius Gražulis, Amy Alexis Sarjeant, Peter Moeck, Jennifer Stone-Sundberg, Trevor J. Snyder, Werner Kaminsky, Allen G. Oliver, Charlotte L. Stern, Louise N. Dawe, Denis A. Rychkov, Evgeniy A. Losev, Elena V. Boldyreva,, Joseph M. Tanski, Joel Bernstein, Wael M. Rabeh, Katherine A. Kantardjieff

Physics Faculty Publications and Presentations

There are many methods that can be used to incorporate concepts of crystallography into the learning experiences of students, whether they are in elementary school, at university or part of the public at large. It is not always critical that those who teach crystallography have immediate access to diffraction equipment to be able to introduce the concepts of symmetry, packing or molecular structure in an age- and audience-appropriate manner. Crystallography can be used as a tool for teaching general chemistry concepts as well as general research techniques without ever having a student determine a crystal structure. Thus, methods for younger …

Learning Support Effectiveness In Mathematics At A Tennessee University, Mark Dula

Electronic Theses and Dissertations

Every year thousands of students graduate from high school and move on to higher education, but many of them are not yet prepared for college level courses. The Tennessee Board of Regents does not currently allow 4-year institutions to teach courses that are below college level, so many institutions are using programs such as learning support courses to assist a growing population of underprepared students. The purpose of this study was to determine if the 1-term and 2-term retention rates for students with the same ACT mathematics subsection scores were different between students who took a regular section of Probability …

"Socratic Circles Are A Luxury": Exploring The Conceptualization Of A Dialogic Tool In Three Science Classrooms, Michelle Renee Copelin

Graduate Theses and Dissertations

Research has shown that dialogic instruction promotes learning in students. Secondary science has traditionally been taught from an authoritative stance, reinforced in recent years by testing policies requiring coverage. Socratic Circles are a framework for student-led dialogic discourse, which have been successfully used in English language arts and Social studies classrooms. The purpose of this research was to explore the implementation process of Socratic Circles in secondary science classes where they have been perceived to be more difficult. Focusing on two physical science classes and one chemistry class, this study described the nature and characteristics of Socratic Circles, teachers’ dispositions …

A Comparison Of Beliefs And Attitudes About Body Image, Eating And Weight Between Incarcerated And Non-~Incarcerated Females, Anne R. Lindsay

UNLV Theses, Dissertations, Professional Papers, and Capstones

Abstract

Incarceration and substance abuse are two of the largest public health issues in America. While the U.S. makes up only 5% of the world’s population, it accounts for 25% of its prisoners. Incarceration affects more than 2.2 million individuals who will eventually return to their families and communities with ongoing family, social and health issues. Women in prison are a particularly vulnerable and underserved population, generally of low education and socio-economic status and although they account for a small percent of the prison population, many are mothers of young children who are likely to become incarcerated themselves. Substance abuse …

Mathematical Interactions Between Teachers And Students In The Finnish Mathematics Classroom, Paula Jeffery Prestwich

Theses and Dissertations

The Finnish school system has figured prominently in the PISA international assessments for over 10 years. Many reasons are given for Finnish success yet few of them focus on what is happening in the mathematics classroom. This study addresses the question of “What does mathematics instruction in the Finnish mathematics classroom look like?” Eight Finnish mathematics classes, from 6th – 9th grade were recorded, translated, and analyzed using the Mathematical Quality of Instruction (MQI) 2013 video coding protocol. Other aspects and observations of these classes also are discussed. Although the study is small, this study gives a view into the …

Matched, Somewhat-Matched Or Mismatched? Predictors Of Degree-Job Match Among Stem Graduates, Taghreed Ahmed Alhaddab

Seton Hall University Dissertations and Theses (ETDs)

The current third-generation globalization caused structural, organizational and functional changes in the STEM workforce along with changes in human capital flow. The new globalization shift produced new world order causing the STEM workforce to adopt new frameworks, new skills, and new policy approaches to maintain economic strength and achieve growth and prosperity. Available data indicate that the U.S. secondary and postsecondary education system prepares and produce more than an adequate number of STEM graduates. The perceived crisis in the number of U.S. STEM graduates was not confirmed by any data or policy report. Thus, attention should not be caught simply …

Assessment Of Learning Gains In A Flipped Biochemistry Classroom, Deanna Dahlke Ojennus

Chemistry Faculty Scholarship

The flipped classroom has become an increasingly popular pedagogical approach to teaching and learning. In this study, learning gains were assessed in a flipped biochemistry course and compared to gains in a traditional lecture. Although measured learning gains were not significantly different between the two courses, student perception of learning gains did differ and indicates a higher level of satisfaction with the flipped lecture format.

Is Stem For All? Perspectives Of Black And Latino Students On Stem Motivation, Adrienne Coleman

Publications & Research

This presentation takes an intricate look at the factors that motivate gifted and talented Black and Latino students to engage in science, technology, engineering and mathematics(STEM). According to the literature, the U.S. workforce could employ as many as 140,000 additional Black and Latino college graduates in STEM fields annually if the gap in college completion by Blacks and Latinos closed to roughly match that of the White and Asian student graduation rates. Thus, the goal of this presentation is to inform administrators, educators, and programs of a 5-step motivation-based program that encourages Black and Latino students to engage in STEM.

Deaf Children’S Science Content Learning In Direct Instruction Versus Interpreted Instruction, Kim B. Kurz, Brenda Schick, Peter C. Hauser

Journal of Science Education for Students with Disabilities

This research study compared learning of 6-9th grade deaf students under two modes of educational delivery – interpreted vs. direct instruction using science lessons. Nineteen deaf students participated in the study in which they were taught six science lessons in American Sign Language. In one condition, the lessons were taught by a hearing teacher in English and were translated in ASL via a professional and certified interpreter. In the second condition, the lessons were taught to the students in ASL by a deaf teacher. All students saw three lessons delivered via an interpreter and three different lessons in direct ASL; …

What I Taught My Stem Instructor About Teaching: What A Deaf Student Hears That Others Cannot, Annemarie Ross, Randy K. Yerrick

Journal of Science Education for Students with Disabilities

Overall, science teaching at the university level has remained in a relatively static state. There is much research and debate among university faculty regarding the most effective methods of teaching science. But it remains largely rhetoric. The traditional lecture model in STEM higher education is limping along in its march toward inclusion and equity. The NGSS and Common Core reform efforts do little to help university science teachers to change their orientation from largely lecture-driven practice with laboratory supplements. While it is impossible to address all diverse student groups, the need for accommodations tend to be overlooked. As a Deaf …

Effect Of An Engineering Camp On Students’ Perceptions Of Engineering And Technology, Rebekah Hammack, Toni A. Ivey, Juliana Utley, Karen A. High

Journal of Pre-College Engineering Education Research (J-PEER)

Students’ knowledge about a profession influences their future decisions about careers. Research indicates that students tend to hold stereotypical views of engineers, which would hinder engineering as a career choice. The purpose of this study was to measure how participating in a week long engineering summer camp affected middle school students’ (N519) attitudes towards engineering and their conceptions of engineering and technology. Results indicate that participation in the programs had a positive impact on the students’ understandings of what technology is and the work engineers do. Although the results indicate a positive impact on participants, it is not clear which …

USF Tampa Graduate Theses and Dissertations

The present study had two main objectives. The first was to determine the degree of understanding of climate change, sea level and sea level rise among middle school students. Combining open-ended questions with likert-scaled questions, we identified student conceptions on these topics in 86 students from 7^th and 8^th grades during 2012 and 2013 before and after implementing a Curriculum Unit (CU). Additional information was obtained by adding drawings to the open-ended questions during the second year to gauge how student conceptions varied from a verbal and a visual perspective. Misconceptions were identified both pre- and post-CU among …

Assessing Student Perceptions Of Indigenous Science Co-Educators, Interest In Stem, And Identity As A Scientist: A Pilot Study, Sarah Alkholy, Fidji Gendron, Tanya Dahms, Maria Pontes Ferreira

Nutrition and Food Science Faculty Research Publications

Minorities are underrepresented in the science, technology, engineering, and mathematics (STEM) workforce, post-secondary STEM education, and show high academic attrition rates. Academic performance and retention improve when culturally relevant support is provided. The interface of Western science and Indigenous science provides an opportunity for bridging this divide. We hypothesized that there would be regional (U.S.A. vs. Canada) differences amongst post-secondary students regarding these variables: perceptions of traditional Elders as STEM co-educators; interest in STEM; and self-identity as a scientist. We conducted a short-term longitudinal pilot study of an interdisciplinary, multi-institutional, and cross-cultural STEM course in the spring of 2013. This …

Inquiry-Based Experiments For Large-Scale Introduction To Pcr And Eestriction Enzyme Digests, Kelly E. Johanson, Terry J. Watt

Faculty and Staff Publications

Polymerase chain reaction and restriction endonuclease digest are important techniques that should be included in all Biochemistry and Molecular Biology laboratory curriculums. These techniques are frequently taught at an advanced level, requiring many hours of student and faculty time. Here we present two inquiry-based experiments that are designed for introductory laboratory courses and combine both techniques. In both approaches, students must determine the identity of an unknown DNA sequence, either a gene sequence or a primer sequence, based on a combination of PCR product size and restriction digest pattern. The experimental design is flexible, and can be adapted based on …

The Implications Of Teacher Performance Assessment And The Impact On Teacher Decision Making, Renee Rice Moran

ETSU Faculty Works

The issue of teacher accountability has been a part of the educational conversation for three decades, but only recently has this conversation been translated into policy as states begin directly tying teacher evaluation scores in part to student achievement on standardized tests. This qualitative study focuses on a group of teachers who are participating in this new form of evaluation (containing both qualitative and quantitative elements including test scores and lesson observations) and examines how they perceived the process. In particular, the study looks at how their personal reactions to a high-stakes evaluation impacted their instructional decision making in their …

How Science Teachers Balance Religion And Evolution In The Science Classroom: A Case Study Of Science Classes In A Florida Public School District, Pierre Willems

Doctoral Dissertations and Projects

The purpose of this case study was to research how science teachers balance both religion and evolution in the science classroom with as little controversy as possible. In this study I attempted to provide some insight on how teachers are currently teaching evolution in their science classes in light of the religious beliefs of the students as well as their own. The case study was conducted in a school district in Florida where I attempted to answer the following questions: (a) How do science teachers in the Florida School District (FSD) approach the religion–evolution issue in preparing students for a …

Academic And Peer Status In The Mathematical Life Stories Of Students, Carol Ann Wise

Theses and Dissertations

Mathematics students often define themselves by their grades, test scores, how they compare to other people, how comfortable they feel in mathematics class, and so on. These experiences are all part of a student's mathematical life story. Students assume positions with particular rights and duties for themselves and for the actors in the stories they tell. Those positions reflect certain types and levels of status. Those types and levels of status have been shown to either inhibit or open a student's access to learning mathematics. Thus, a student's status in mathematics education is an issue of equity. Mathematics educators and …
