An Integrated Approach To The Teaching Of Numerical Methods To Engineering Students, Garrett Keane, Michael Carr, Patrick Carroll

Conference papers

In Technological University Dublin, historically, numerical methods were taught to engineering students using a format of traditional mathematics lectures, to a large class group consisting of students from five different engineering disciplines, complemented by small class tutorials. Assessment was by a single, written exam only.

In order to improve the overall effectiveness of the students’ learning experience, it was deemed beneficial to also introduce practical computing classes in which the students would be required to apply the general mathematical methods covered in lectures to discipline-specific examples.

Three different practical computing assignments were devised for the students to undertake, and 20% …

Analogical Reasoning In The Engineering Design Process And Technology Education Applications, Jenny Daugherty, Nathan Mentzer

Publications

This synthesis paper discusses the research exploring analogical reasoning, the role of analogies in the engineering design process, and educational applications for analogical reasoning. Researchers have discovered that analogical reasoning is often a fundamental cognitive tool in design problem solving. Regarding the possible role of analogical reasoning in the context of technology education; analogies may be a useful tool to develop student’s design skills, teach abstract or complex concepts, and build students’ analogical reasoning skills for general problem solving. The positive and negative educational implications of analogical reasoning being explored by researchers are also discussed.

Temperature Dependence Of A Macrobending Edge Filter Based On A High-Bend Loss Fiber, Pengfei Wang, Ginu Rajan, Yuliya Semenova, Gerald Farrell

Articles

The temperature dependence of a macrobending bare fiber based edge filter is investigated both theoretically and experimentally. The fiber used is a high bend loss fiber, type 1060XP. The experimental results show a good agreement with the proposed theoretical model over a temperature range from 0 to 80oC. It is shown that the strong temperature dependence of a high-bend loss fiber has a significant influence on the performance of a fiber edge filter used in a wavelength measurement application. However it is also concluded that such a temperature dependent performance can be beneficially utilized in a fiber temperature sensing application.

2007 Fall Engr333/Biol354 Project Final Report, 2007 Fall Engr333, 2007 Fall Biol354

ENGR 333

The students of Calvin College’s Engineering 333 and Biology 354 classes were given the task of determining “What would it take to make Calvin College Carbon Neutral?” At first glance, it would not appear that classes on Advanced Thermal System Design and Investigations in Plant Ecology would have much in common. However, the biology and engineering students comprising these classes banded together to tackle the problem. Coming to a satisfactory conclusion would require:

• Creating an inventory of Green House Gas (GHG) emissions and sequestration potential
• Coming up with detailed solutions to achieve Carbon Neutrality
• Working out a practical schedule to …

2007 Fall Engr333/Biol354 Project Solutions Poster, 2007 Fall Engr333, 2007 Fall Biol354

ENGR 333

A carbon footprint is term which refers to the net amount of greenhouse gases produced to directly or indirectly by human activities and is usually expressed in terms of metric tons of carbon dioxide. The Calvin community places a strong emphasis on practicing good stewardship, including stewardship of Creation. Reducing Calvin’s carbon footprint is crucial because carbon dioxide is a major greenhouse gas and contributes heavily to global climate change. In a previous portion of this project, the carbon footprint of Calvin College was calculated to be about 66,400 MTCE (Metric Tons Carbon dioxide Emitted). The goal of this portion …

Relaxation Time, Diffusion, And Viscosity Analysis Of Model Asphalt Systems Using Molecular Simulation, Liqun Zhang, Michael L. Greenfield

Chemical, Biomolecular, and Materials Engineering Faculty Publications

Molecular dynamics simulation was used to calculate rotational relaxation time, diffusion coefficient, and zero-shear viscosity for a pure aromatic compound naphthalene and for aromatic and aliphatic components in model asphalt systems over a temperature range of 298–443 K. The model asphalt systems were chosen previously to represent real asphalt. Green–Kubo and Einstein methods were used to estimate viscosity at high temperature 443.15 K. Rotational relaxation times were calculated by nonlinear regression of orientation correlation functions to a modified Kohlrausch–Williams–Watts function. The Vogel–Fulcher–Tammann equation was used to analyze the temperature dependences of relaxation time, viscosity, and diffusion coefficient. The temperature dependences …

2007 Engr333/Biol354 Project Assignment, Matthew K. Heun

ENGR 333

The Fall 2007 semester ENGR333 project involved a collaboration with students in BIOL354, taught by my colleague Dave Warners. We asked our students “What would it take to make Calvin College carbon neutral?”

This project resulted in the first-ever carbon dioxide emissions and sequestration assessment of Calvin College, attached below.

The student presenters animated the pie charts, and an audible gasp filled the hall when the imbalance between carbon emissions and carbon sequestration became clear.

The students also studied potential routes to carbon neutrality, one of which was a green revolving fund.

This class project resulted in a co-authored publication …

The Theory Of Planned Behavior As A Model Of Academic Dishonesty In Engineering And Humanities Undergraduates, Trevor S. Harding, Mathew J. Mayhew, Cynthia J. Finelli, Donald D. Carpenter

Materials Engineering

This study examines the use of a modified form of the Theory of Planned Behavior in understanding the decisions of undergraduate students in engineering and humanities to engage in cheating. We surveyed 527 randomly selected students from three academic institutions. Results supported the use of the model in predicting ethical decision-making regarding cheating. In particular, the model demonstrated how certain variables (gender, discipline, high school cheating, education level, international student status, participation in Greek organizations or other clubs) and moral constructs related to intention to cheat, attitudes toward cheating, perceptions of norms with respect to cheating, and ultimately, cheating behaviors. …

Computer-Based Instruction For Engineering Education In The Developing World, Bradford G. Singley

Theses and Dissertations

Although civil engineers continually develop new ways to solve problems involving water, energy, infrastructure and environmental sustainability, these innovations can take years – or even decades – to reach developing countries. Computer-based instruction has the potential to dramatically decrease this lag time by improving engineering education in the developing world. This paper discusses the development of instructional simulations, based on the theory of model-centered instruction. These simulations can serve as self-paced learning modules, which can be accessed for free over the Internet. A pilot learning module was developed for the United Nations Educational Scientific and Cultural Organization (UNESCO) on the …

A Hybrid First Year Science Course For Engineering Students – Integrating Biology With Chemistry, David Harding, Pauline Schwartz, Jean Nocito-Gobel, Agamemnon Koutsospyros

Civil Engineering Faculty Publications

Biology is playing an increasingly important role in many engineering fields. With the typical engineering program already having a high credit hour requirement, the question becomes, how to best integrate biology concepts into a packed engineering curriculum. A typical biology course is not likely to introduce the important concepts of biology to engineering students. The solution here is to develop a hybrid course that integrates chemistry and biology. In the course, Chemistry with Applications to Biosystems, the concept is to develop a course that integrally links important concepts of chemistry and biology. The course focuses on the areas of biology …
