Undergraduate Engineering Students' Understanding Of Heat, Temperature, And Radiation, Katharyn Nottis, Michael Prince, Margot Vigeant, Sarah Nelson, Kathryn Hartsock

Michael J. Prince

Difficulty understanding heat and temperature concepts has been recognized in engineering education. Confusion has been shown to persist after instruction. The purpose of this study was to determine whether undergraduate engineering students’ knowledge of four heat transfer concept areas significantly changed with instruction and whether this varied by major and GPA. Two hundred twenty-eight undergraduate engineering students from six institutions were assessed prior to and after instruction. Results showed significant improvement in most concept areas but mean scores were below mastery. Previously documented misconceptions persisted after instruction. Significant differences were found by major and GPA. Suggestions for future research provided.

Addressing Misconceptions About Heat Transfer In Undergraduate Chemical Engineering Instruction, Katharyn E. K. Nottis, Michael J. Prince, Margot A. Vigeant

Michael J. Prince

Understanding heat, energy and temperature can be difficult. Misconceptions about heat transfer have been found to persist, even after instruction. New instructional methods are needed to address them. This pilot study examined whether researcher-developed, inquiry-based activities could increase conceptual understanding of heat transfer. Twenty-two undergraduate chemical engineering students were assessed before and after instruction with inquiry-based activities. Participants had significantly higher scores on the post-test. An examination of assessment questions revealed substantial improvement on questions closely related to activities. However, participants had difficulty applying concepts in new and related contexts. Educational implications and suggestions for future research will be discussed.

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 ...

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

Dissertations

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 ...

Investigating Macroscopic, Submicroscopic, And Symbolic Connections In A College-Level General Chemistry Laboratory, Felicia Culver Thadison 2011 University of Southern Mississippi

Investigating Macroscopic, Submicroscopic, And Symbolic Connections In A College-Level General Chemistry Laboratory, Felicia Culver Thadison

Dissertations

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 ...

A Mathematician Weighs In On The Evolution Debate, Kris H. Green 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, Firuz Kamalov 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

Chris Plouff

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, Kelly Beatrice Campbell 2011 Brigham Young University - Provo

How Student Positioning Can Lead To Failure In Inquiry-Based Classrooms, Kelly Beatrice Campbell

All 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 ...
