There is broad interest within colleges and universities to provide courses that examine “The Big Questions” of human experience from a variety of perspectives. The study of the history of discoveries and insights that we have gained through the development of astrophysics and cosmology provides course options for students to use to explore ...
Matlab Based Algorithm To Find The Remaining State Of Charge, 2011 San Jose State University
Matlab Based Algorithm To Find The Remaining State Of Charge, Ishrat Khatoon, Bhaskar Saha, Kai Goebe
STAR (STEM Teacher and Researcher) Presentations
Li-ion batteries are one of the most common rechargeable batteries used in portable electronics, electric vehicles, military operations and aerospace applications such as electric air-crafts, spacecrafts, space rovers, robots, etc. Failure of these batteries could lead to reduced performance, operational impairment and even catastrophic failure, especially in aerospace systems. Monitoring the remaining state of charge (RSOC) of these batteries would greatly improve the reliability of the systems powered by them and will ultimately lengthen their lifetimes. NASA's Mars Global Surveyor spacecraft was lost due to battery failure. Hence, it is very important to find the RSOC of the batteries ...

With this in mind, the purpose of this research was to examine the effects of strategy instruction that involved the use of the concrete-representational-abstract teaching sequence on the addition with regrouping computation and word problem-solving skills of students with learning disabilities. This study involved the use of a multiple probe across participants design with two replications. The participants included nine second through sixth graders who had been identified as having a learning disability and were demonstrating mathematics difficulties. There were three females ...
Investigating Macroscopic, Submicroscopic, And Symbolic Connections In A College-Level General Chemistry Laboratory, 2011 University of Southern Mississippi
Investigating Macroscopic, Submicroscopic, And Symbolic Connections In A College-Level General Chemistry Laboratory, Felicia Culver Thadison
Explanations of chemical phenomena rely on understanding the behavior of submicroscopic particles. Because this level is “invisible,” it is described using symbols such as models, diagrams and equations. For this reason, students often view chemistry as a “difficult” subject. The laboratory offers a unique opportunity for the students to experience chemistry macroscopically as well as symbolically. The purpose of this investigation was to determine how chemistry lab students explained chemical phenomenon on the macroscopic, submicroscopic, and representational/symbolic level. The participants were undergraduate students enrolled in an introductory level general chemistry lab course. Students’ background information (gender, the number of ...

Factors That Contribute To Persistence And Retention Of Underrepresented Minority Undergraduate Students In Science, Technology, Engineering, And Mathematics (Stem), Sidney Kirk Mitchell
The objective of this research was to identify specific factors that contribute to underrepresented minority (African American, Hispanic, Native American) undergraduate students‟ success in STEM disciplines at a regional university during the 2007-2010 timeframe. As more underrepresented minority (URM) students complete STEM degrees, many will possess the skills to become part of the domestic human capital needed to meet U. S. workforce demands and enhance the nation‟s STEM innovation. According to Burke and Mattis (2007), the lack of URM students in STEM education and in the workforce is one of the major contributors to STEM shortages in the United ...
Does The Use Of A Graphing Calculator Tutorial Affect The Attitudes, Achievement, And Calculator Ability Of Non-Mathematics Majors In A Calculus Course?, 2011 University of Southern Mississippi
Does The Use Of A Graphing Calculator Tutorial Affect The Attitudes, Achievement, And Calculator Ability Of Non-Mathematics Majors In A Calculus Course?, Kari Michelle Everett
The use of graphing calculators in a mathematics classroom is becoming more common place. Teaching with technology has allowed for advancements in the rapidity with which students learn and the degree to which they retain the material taught. As a result, teachers have time to delve more deeply into mathematical topics that might otherwise have merely been touched upon.
This study shows the effects of a graphing calculator tutorial for non-mathematics major students taking calculus as a required course. Qualitative methods were used in order to provide information about the types of students taking a calculus course for nonmathematic students ...

A Mathematician Weighs In On The Evolution Debate, 2011 St. John Fisher College
A Mathematician Weighs In On The Evolution Debate, Kris H. Green
Journal of Humanistic Mathematics
There are a variety of reasons underlying the lack of public acceptance for the theory of evolution in the United States. An overlooked cause is related to problems with the mathematics curriculum in the K-12 setting. In this essay, we examine this relationship and propose changes to the mathematics curriculum that could improve mathematical thinking while also providing a basis for understanding theories, like evolution, that are poorly understood.

Covariant Representations Of C*-Dynamical Systems Involving Compact Groups, 2011 University of Nebraska-Lincoln
Covariant Representations Of C*-Dynamical Systems Involving Compact Groups, Firuz Kamalov
Dissertations, Theses, and Student Research Papers in Mathematics
Given a C*-dynamical system (A, G, σ) the crossed product C*-algebra A x σG encodes the action of G on A. By the universal property of A x σG there exists a one to one correspondence between the set all covariant representations of the system (A, G, σ) and the set of all *-representations of A x σG. Therefore, the study of representations of A x σG is equivalent to that of covariant representations of (A, G, σ).
We study induced covariant representations of systems involving compact groups. We prove that every irreducible (resp ...

Embedding Lifelong Learning Skills Into A First-Year Engineering Course Through Introduction Of An Independent Research Project And Information Literacy Skills, Chris Plouff, Debbie Morrow
This paper reports on a work in progress to address ABET program outcome ‘i’ (“graduates have a recognition of the need for, and an ability to engage in, lifelong learning”) in the Bachelor of Science in Engineering programs (mid-size, undergraduate engineering program) at a large Master’s-granting university in the mid-western United States. One performance criterion used by the programs to assess program outcome ‘i’ is the ability to find, evaluate, and effectively use information independently. This concept is introduced in the first-year of the programs, and is reinforced in an intentional thread throughout the curriculum, culminating with the senior ...
How Student Positioning Can Lead To Failure In Inquiry-Based Classrooms, 2011 Brigham Young University - Provo
How Student Positioning Can Lead To Failure In Inquiry-Based Classrooms, Kelly Beatrice Campbell
Theses and Dissertations
In an effort to improve mathematics instruction, I studied how the positions students choose or are pressed to take on can lead to failure in an inquiry-based classroom. Positioning refers to the temporary roles that a student or a teacher can place each other in or take on in a given classroom environment. Since positions are constructed and maintained by language use, I drew from positioning theory and discourse theory for my theoretical framework. From analyzing transcripts of classroom episodes and interviews with the teacher and a student, I identified common positions that the teacher and the student took on ...
Parts Of The Whole: An Algebra Lesson, 2011 Dartmouth College
Parts Of The Whole: An Algebra Lesson, Dorothy Wallace
This column draws on research of Eon Harper to demonstrate how an understanding of his proposed stages of algebra acquisition would inform a systemic overhaul of algebra education. Harper's stages also explain why students may pass a series of algebra courses yet still be unable to make sense of calculus, as well as offering insight on what aspects of algebra support quantitative literacy.
Reducing Math Anxiety: Findings From Incorporating Service Learning Into A Quantitative Reasoning Course At Seattle University, Allison Henrich, Kristi Lee
How might one teach mathematics to math-anxious students and at the same time reduce their math anxiety? This paper describes what we found when we incorporated a service learning component into a quantitative reasoning course at Seattle University in Fall 2010 (20 students) and Spring 2011 (28 students). The course is taken primarily by humanities majors, many of whom would not take a course in math if they didn’t need to satisfy the university’s core requirement. For the service learning component, each student met with and tutored children at local schools for 1-2 hours per week (total about ...
Quantitative Reasoning In The Contemporary World, 3: Assessing Student Learning, 2011 Central Washington University
Quantitative Reasoning In The Contemporary World, 3: Assessing Student Learning, Stuart Boersma, Caren Diefenderfer, Shannon W. Dingman, Bernard L. Madison
In this third paper in a series describing the Quantitative Reasoning in the Contemporary World course, the authors provide an adaptation of the Association of American Colleges and Universities quantitative literacy VALUE rubric. Describing achievement levels in six core competencies (interpretation, representation, calculation, analysis/synthesis, and communication), the resulting Quantitative Literacy Assessment Rubric (QLAR) is applicable to grading student work and has exhibited a high degree of reliability in two separate scoring tests (97% and 88% respectively). The distribution of the six core competencies across the 24 case studies in the authors’ quantitative reasoning casebook shows that interpretation, calculation, and ...
Constructivist And Behaviorist Approaches: Development And Initial Evaluation Of A Teaching Practice Scale For Introductory Statistics At The College Level, Rossi A. Hassad
This study examined the teaching practices of 227 college instructors of introductory statistics from the health and behavioral sciences. Using primarily multidimensional scaling (MDS) techniques, a two-dimensional, 10-item teaching-practice scale, TISS (Teaching of Introductory Statistics Scale), was developed. The two dimensions (subscales) are characterized as constructivist and behaviorist; they are orthogonal. Criterion validity of the TISS was established in relation to instructors’ attitude toward teaching, and acceptable levels of reliability were obtained. A significantly higher level of behaviorist practice (less reform-oriented) was reported by instructors from the U.S., as well as instructors with academic degrees in mathematics and engineering ...
