Development Of A Problem-Based Learning Matrix For Data Collection, Shannon M. Sipes Dec 2016

Development Of A Problem-Based Learning Matrix For Data Collection, Shannon M. Sipes

Interdisciplinary Journal of Problem-Based Learning

Few of the papers published in journals and conference proceedings on problem-based learning (PBL) are empirical studies, and most of these use self-report as the measure of PBL (Beddoes, Jesiek, & Borrego, 2010). The current study provides a theoretically derived matrix for coding and classifying PBL that was objectively applied to official curriculum documentation in a content analysis. The results for the level of problem-based learning in two engineering program curricula are presented. By introducing such a matrix, this study offers a tool that can be applied by other scholars examining PBL, creating consistency in methodology, definitions, and language among scholars.


Conceptual Understanding Of Threshold Concepts Of Electrical Phenomena: Mental Models Of Senior Undergraduates In Electrical Engineering, Mark T. Carnes Dec 2016

Conceptual Understanding Of Threshold Concepts Of Electrical Phenomena: Mental Models Of Senior Undergraduates In Electrical Engineering, Mark T. Carnes

Open Access Dissertations

Every field of study has a set of domain-specific concepts that anyone who desires to work in that field must know and understand. Most students who pursue university degrees in engineering trust that their education is designed to provide them with this knowledge. But does it? In electrical engineering (EE), conceptual understanding of electrical phenomena has rarely been addressed. Even though the presumed goal of instructors and students alike is to learn the concepts of electrical phenomena well enough to be able to use the concepts to design useful things, it is difficult to determine whether this goal is being ...


Race, Class And Gender In Engineering Education: A Quantitative Investigation Of First Year Enrollment, Canek Moises Luna Phillips Dec 2016

Race, Class And Gender In Engineering Education: A Quantitative Investigation Of First Year Enrollment, Canek Moises Luna Phillips

Open Access Dissertations

Research explanations for the disparity across both race and gender in engineering education has typically relied on a deficit model, whereby women and people of color lack the requisite knowledge or psychological characteristics that Whites and men have to become engineers in sufficient numbers. Instead of using a deficit model approach to explain gender and race disparity, in the three studies conducted for this dissertation, I approach gender and race disparity as the result of processes of segregation linked to the historic and on-going perpetuation of systemic sources of oppression in the United States. In the first study, I investigate ...


Carbon Nanotube Thermal Interfaces And Related Applications, Stephen L. Hodson Dec 2016

Carbon Nanotube Thermal Interfaces And Related Applications, Stephen L. Hodson

Open Access Dissertations

The development of thermal interface materials (TIMs) is necessitated by the temperature drop across interfacing materials arising from macro and microscopic irregularities of their surfaces that constricts heat through small contact regions as well as mismatches in their thermal properties. Similar to other types of TIMs, CNT TIMs alleviate the thermal resistance across the interface by thermally bridging two materials together with cylindrical, high-aspect ratio, and nominally vertical conducting elements. Within the community of TIM engineers, the vision driving the development of CNT TIMs was born from measurements that revealed impressively high thermal conductivities of individual CNTs. This vision was ...


The Association Between Tolerance For Ambiguity And Fear Of Negative Evaluation: A Study Of Engineering Technology Capstone Courses, Sergey I. Dubikovsky Dec 2016

The Association Between Tolerance For Ambiguity And Fear Of Negative Evaluation: A Study Of Engineering Technology Capstone Courses, Sergey I. Dubikovsky

Open Access Dissertations

For many students in engineering and engineering technology programs in the US, senior capstone design courses require students to form a team, define a problem, and find a feasible technical solution to address this problem. Students must integrate the knowledge and skills acquired during their studies at the college or university level. These truly integrative design activities do not have a single “correct” solution. Instead, there is an array of solutions, many of which could be used to achieve the final result. This ambiguity can cause students to experience anxiety during the projects.

This study examined the main topics: • To ...


Students' Explanations In Complex Learning Of Disciplinary Programming, Camilo Vieira Dec 2016

Students' Explanations In Complex Learning Of Disciplinary Programming, Camilo Vieira

Open Access Dissertations

Computational Science and Engineering (CSE) has been denominated as the third pillar of science and as a set of important skills to solve the problems of a global society. Along with the theoretical and the experimental approaches, computation offers a third alternative to solve complex problems that require processing large amounts of data, or representing complex phenomena that are not easy to experiment with. Despite the relevance of CSE, current professionals and scientists are not well prepared to take advantage of this set of tools and methods. Computation is usually taught in an isolated way from engineering disciplines, and therefore ...


Detangling The Interrelationships Between Self-Regulation And Ill-Structured Problem Solving In Problem-Based Learning, Xun Ge, Victor Law, Kun Huang Oct 2016

Detangling The Interrelationships Between Self-Regulation And Ill-Structured Problem Solving In Problem-Based Learning, Xun Ge, Victor Law, Kun Huang

Interdisciplinary Journal of Problem-Based Learning

One of the goals for problem-based learning (PBL) is to promote self-regulation. Although self-regulation has been studied extensively, its interrelationships with ill-structured problem solving have been unclear. In order to clarify the interrelationships, this article proposes a conceptual framework illustrating the iterative processes among problem-solving stages (i.e., problem representation and solution generation) and self-regulation phases (i.e., planning, execution, and reflection). The dynamics of the interrelationships are further illustrated with three ill-structured problem-solving examples in different domains (i.e., information problem solving, historical inquiry, and science inquiry). The proposed framework contributes to research and practice by providing a new ...


A Study Of Applications Of 3d Animation For Emergency Medicine Pedagogy, Huilong Zheng Aug 2016

A Study Of Applications Of 3d Animation For Emergency Medicine Pedagogy, Huilong Zheng

Open Access Theses

There is ample precedent for the use of 3D animation in education, though little research on specific applications in the field of medicine. An experiment was carried out to assess the suitability of 3D animation for educational purposes in emergency medicine courses. Two groups of experimental participants were assessed on their ability to respond to three emergency medical situations in simulated test scenarios. Both groups received equivalent information on how to treat the three different medical emergencies. The control group received the information in traditional lecture format. The experimental group instead received the information from a set of 3D animations ...

Methods To Facilitate Community Participation In Humanitarian Engineering Projects: Laying The Foundation For A Learning Platform, Andrea Mazzurco

Open Access Dissertations

Humanitarian engineering (HE) is a new interdisciplinary field that is rapidly emerging worldwide. Many not-for-profit organizations such as Engineers Without Borders, Practical Action, and International Development Enterprise have been flourishing with the goal of providing technological solutions to those who need them the most. In engineering programs across the U.S., HE, service-learning, community engagement, and similar programs are gaining popularity because they offer an efficient way to meet ABET accreditation criteria, while also teaching valuable technical and professional skills to engineering students. However, the cultural, social, and political differences among communities and engineers often add degrees of difficulty that ...


Development Of First-Year Engineering Teams' Mathematical Models Through Linked Modeling And Simulation Projects, Kelsey Joy Rodgers Aug 2016

Development Of First-Year Engineering Teams' Mathematical Models Through Linked Modeling And Simulation Projects, Kelsey Joy Rodgers

Open Access Dissertations

The development and use of mathematical models and simulations underlies much of the work of engineers. Mathematical models describe a situation or system through mathematics, quantification, and pattern identification. Simulations enable users to interact with models through manipulation of input variables and visualization of model outputs. Although modeling skills are fundamental, they are rarely explicitly taught in engineering. Model-eliciting activities (MEAs) represent a pedagogical approach used in engineering to teach students mathematical modeling skills through the development of a model to solve an authentic problem.

This study is an investigation into the impact of linking a MEA and a simulation-building ...

From Mechanic To Designer: Evolving Perceptions Of Elementary Students Over Three Years Of Engineering Instruction, Anastasia M. Rynearson

Open Access Dissertations

Due in part to increasing state standards that require engineering in K-12 curricula and the Next Generation Science Standards’ incorporation of engineering outcomes, inclusion of engineering into elementary classrooms is on the rise. Teacher development and experiences in learning about and implementing engineering have been studied, but elementary students’ experiences when learning about engineering have not been explored.

The purpose of this study is to address the question: How do elementary students’ knowledge of, attitudes toward, and overall conceptions of engineering evolve over three years of engineering instruction?

This study follows seven elementary school students through three years of engineering ...


Promoting Teaming Metacognition, Lee Kemp Rynearson Aug 2016

Promoting Teaming Metacognition, Lee Kemp Rynearson

Open Access Dissertations

Improving students’ capacity to effectively perform teaming skills is a crucial outcome for engineering education, and has been the subject of considerable prior and ongoing research. Based upon review of research on teaming, it was hypothesized that greater awareness of appropriate opportunities to use teaming skills in authentic contexts would lead to greater teaming skills employment over time. Further, it was hypothesized that greater psychological safety in student teams would lead to more students choosing to employ appropriate teaming skills over time. An intervention to achieve such increases could therefore be expected to promote student teaming skills performance improvement. Seeking ...


Exploratory Study Of Students' Representational Fluency And Competence Of Electric Circuits, William Fernando Sandchez Cossio Aug 2016

Exploratory Study Of Students' Representational Fluency And Competence Of Electric Circuits, William Fernando Sandchez Cossio

Open Access Theses

Electric circuits are extensively used in today’s devices as computers, phones, cameras and others. This makes them a crucial topic in engineering because almost every engineering branch could be related of used them at different levels. Even though their importance, students often struggle during the learning process of circuit analysis topics. Additionally, other very important abilities for engineering students are the capacities to create, use, express and think about models and representations of technical concepts; and the capacities to translate and map from one representation to another. These abilities are known as representational competence and representational fluency respectively.

The ...


Why This Flip Wasn't A Flop: What The Numbers Don't Tell You About Flipped Classes, Heather Noel Fedesco, Troy Cary Jun 2016

Why This Flip Wasn't A Flop: What The Numbers Don't Tell You About Flipped Classes, Heather Noel Fedesco, Troy Cary

IMPACT Publications

This paper details the conversion of a large, required Civil Engineering fluid mechanics course into a more student-centered, active learning-oriented course through the flipping of one lecture per week. In the flipped class, students collaboratively solve homework problems in groups while receiving “expert” feedback from instructors and TAs. To offset the lost lectures, some course material that has been delivered in traditional lectures has been placed online in the form of short videos and textbook readings, with low-stakes quizzes for assessment.

Student learning gains were quantitatively assessed by comparing quiz and final exam scores for three semesters (1 pre-flip and ...


Professional Development For The Integration Of Engineering In High School Stem Classrooms, Jonathan E. Singer, Julia M. Ross, Yvette Jackson-Lee Jun 2016

Professional Development For The Integration Of Engineering In High School Stem Classrooms, Jonathan E. Singer, Julia M. Ross, Yvette Jackson-Lee

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

Science, Technology, Engineering, and Mathematics (STEM) education in the U.S. is in transition. The recently published A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas as well as the Next Generation Science Standards are responsive to this call and clearly articulate a vision that includes engineering practices as key components. This shift presents significant challenges to school districts owing to a stark lack of research-based engineering-focused instructional materials and corresponding teacher professional development. The purpose of this study was to investigate the impact of a professional development program on high school STEM teachers’ ability to enact ...

Mining Big Data To Create A Tool For Empirical Observation Of Continuous Safety Improvement In A Construction Company - A Progressive Case Study In The Lean Environment, Nicolas J. Michuda

Open Access Theses

In any iterative process, without a system of measurement, controlled improvement cannot be recorded. This is especially true in the construction industry, where error occurs, often with fatal repercussions. As part of a process to facilitate the establishment of this metric, an entirely new application was created. The goal of this application is to measure the causal factors that lead to incidents, which will allow the user and administration to track the circumstances and types of incidents. This enables the company to focus on these problem areas and improve through training. By analyzing these incident trends over time, the company ...

Learning The Language Of Academic Engineering: Sociocognitive Writing In Graduate Students, Catherine G. P. Berdanier Mar 2016

Learning The Language Of Academic Engineering: Sociocognitive Writing In Graduate Students, Catherine G. P. Berdanier

Open Access Dissertations

Although engineering graduate programs rarely require academic writing courses, the indicators of merit in academic engineering, such as journal publications, successful grants, and doctoral milestones (e.g. theses, dissertations) are based in effective written argumentation and disciplinary discourse. Further, graduate student attrition averages 57% across all disciplines, with some studies classifying up to 50% of these students as “ABD” (All But Dissertation.) In engineering disciplines specifically, graduate attrition rates across the U.S. average 36% (both Master’s and PhD students), according to the Council of Graduate Schools. The lack of socialization is generally noted as a main reason for ...

Modernizing The Current Afghan Engineering Education System: Challenges And Opportunities, Khalilullah Mayar

Open Access Theses

Having an effective engineering education system in place can play a crucial role in the development and reconstruction process of a war-ravaged country, such as Afghanistan, where tens of billions of dollars of international aid has been spent in the past 14 years for that process, including higher education. Unfortunately, at this point, the Afghan engineering education system is not yet financially self-sufficient nor can it address the education requirements of today’s job market. This thesis aimed to identify the major challenges still faced by Afghanistan and to provide a comprehensive list of recommendations and priorities that can make ...


Peer Evaluation Of Team Member Effectiveness As A Formative Educational Intervention, Nathan Mentzer, Dawn Laux, Angelika Zissimopoulos, K. Andrew R. Richards Jan 2016

Peer Evaluation Of Team Member Effectiveness As A Formative Educational Intervention, Nathan Mentzer, Dawn Laux, Angelika Zissimopoulos, K. Andrew R. Richards

IMPACT Publications

Peer evaluation of team member effectiveness is often used to complement cooperative learning in the classroom, by holding students accountable for their team contributions. Drawing on the tenants of self-determination theory, this study investigated the impacts of formative peer evaluation in university level team-based design projects. The hypothesis was that the introduction of formative peer evaluation cycles would result in a more student-centered learning climate, increased competence, reduced doubt, and improved student learning. Two semesters were compared in this quasi-experimental study where results of peer evaluation became modifiers to students’ grades in the final project. In only one of the ...

Evenhouse, Mariana Tafur, Charles Morton Krousgrill, Craig Zywicki, Angelika N. Zissimopoulos, David B. Nelson, Jennifer Deboer, Jeffrey F. Rhoads, Edward J. Berger

Freeform Publications

The Dynamics Concept Inventory (DCI) is a validated assessment tool commonly used to evaluate student growth within core, gateway-level mechanics courses. This research explored the evaluative use of this tool within the context of Freeform – an emergent course system that buttresses active class meetings with blended and collaborative virtual learning environments, themselves founded upon extensive multimedia content and interactive forums – at Purdue University. The paper specifically considers a number of related issues including: (i) the thoughtful development (via expert content validation) and statistical reliability of an abbreviated DCI instrument, which is more amenable to in-class implementation than the much longer ...


A Standards-Based Grading Model To Predict Students' Success In A First-Year Engineering Course, Farshid Marbouti Jan 2016

A Standards-Based Grading Model To Predict Students' Success In A First-Year Engineering Course, Farshid Marbouti

Open Access Dissertations

Using predictive modeling methods, it is possible to identify at-risk students early in the semester and inform both the instructors and the students. While some universities have started to use standards-based grading, which has educational advantages over common score-based grading, at–risk prediction models have not been adapted to reap the benefits of standards-based grading. In this study, seven prediction models were compared to identify at-risk students in a course that used standards-based grading. When identifying at-risk students, it is important to minimize false negative (i.e., type II) errors while not increasing false positive (i.e., type I) errors ...
