A Study On The Micro Electro-Discharge Machining Of Aerospace Materials, Mychal-Drew Moses 2015 Western Kentucky University

A Study On The Micro Electro-Discharge Machining Of Aerospace Materials, Mychal-Drew Moses

Masters Theses & Specialist Projects

Electrical Discharge Machining (EDM) is a non-traditional machining process that uses hundreds of thousands of minute electrical sparks per second to machine any electrically conductive material, no matter the hardness or how delicate it is. EDM allows a much greater range of design possibilities, unconstrained from the traditional machining processes, in which material is removed mechanically by either rotating the cutting tool or the work piece. Shapes that were impossible to machine by any other method, such as deep, precision, square holes and slots with sharp inside corners, are readily produced. It provides accurate geometries in high- aspect ratio holes ...

An Investigation Of The Impact Of A Flipped Classroom Instructional Approach On High School Students' Content Knowledge And Attitudes Toward The Learning Environment, Matthew R. Bell

All Theses and Dissertations

The idea of the “flipped classroom” is a relatively new concept in education that has become increasingly popular. Instructors who flip their classrooms reverse the roles of school work and homework by recording video lectures for students to watch before coming to class. Students then work on their homework in the classroom while the instructor is present to help them. Very little research has been done on the effectiveness of the flipped classroom to determine if students can perform better on exams by learning in a flipped classroom environment, especially for high school demographics. The purpose of this research is ...

Perceptions Of Agricultural College Students On The Relationship Between Quality And Safety In Agricultural Work Environments, Sai K. Ramaswamy, Gretchen A. Mosher 2015 Iowa State University

Perceptions Of Agricultural College Students On The Relationship Between Quality And Safety In Agricultural Work Environments, Sai K. Ramaswamy, Gretchen A. Mosher

Agricultural and Biosystems Engineering Publications

Agriculture is a high-hazard industry that employs a large number of young workers below the age of 25. Recent studies have documented a strong positive correlation between quality management in agriculture and occupational safety as perceived by agricultural workers. Younger workers have been found to be at higher risk for occupational injuries and fatalities in agriculture. Furthermore, college students in agriculture have minimal exposure to safety and quality management principles in their coursework and thus may not be aware that the two concepts are associated. Little research has studied how young workers perceive the relationship between safety and quality and ...

A Highly Adaptive And Cost Effective Second Generation Incubator (Sgi) Towards Educational, Research And Clinical Processes, Yassir H. Al-Sayagh

Biological Systems Engineering--Dissertations, Theses, and Student Research

Today´s rising demand for more reliable and affordable alternatives to organ transplant has led to a growing market for in vitro tissue culture systems. The main objective of tissue engineering as a whole is to employ human tissue equivalents for commercial use. The state-of-the-art processes for producing these so called tissue models are still very expensive, difficult to produce and time-consuming.

To engineer tissues, in vitro, a three-dimensional support structure commonly termed scaffold is needed. Stem cells are then added to the scaffold. In order for tissue to materialize, the scaffold and the cells must be incubated (cultured) at ...

Multiple Learning Strategies And Assessments Used In An Online Technology, Society & Ethics Course, Byron Garry 2014 South Dakota State University

Multiple Learning Strategies And Assessments Used In An Online Technology, Society & Ethics Course, Byron Garry

2014 ASEE North Midwest Section Conference

The author of this article has taught Electronics Engineering Technology courses for 20+ years, mostly in a classroom face-to-face setting. The assessment of student learning depends mostly on the evaluation of how well the students have learned the theory-based, numerically-involved, and hands-on applications of each course’s content. For the past three summers, the author has also taught an on-line course entitled Technology, Society & Ethics. This kind of course calls for an emphasis on discussion and student writing, which requires a very different style of teaching and assessment than the instructor had used in the past. As a preparation for teaching the course for the first time, the learning outcomes of the course were developed before the specific teaching style and assessment process were chosen. Suskie1 says that for good assessment, the instructor at the start needs to “develop clearly articulated written statements of expected learning outcomes”, that is, what will the students know and be able to do by the end of the course.

For the course, the Student Learning Outcomes statements must meet the requirements of three different entities: ABET, the university’s General Education requirements, and the student evaluation of teaching process the university uses, which comes from the IDEA Center2. The IDEA Center has developed a list of twelve Learning Objectives (‘Objective’ as used by IDEA means the same as ‘Outcome’) that the course instructor can choose from, as the focus of the student’s evaluation of the learning the students achieved in the course. The course instructor chose three objectives to focus on: Learning how to find and use resources for answering questions or solving problems; Developing a clearer understanding of, and a commitment to, personal values; and Acquiring an interest in learning more by asking my own questions and seeking answers. Educational research highlighted by the IDEA Center and others show ...

Building An Engineering Honors Curriculum: Collegiate Consistency With Individual Flexibility, Amy Brewster, Robert Kirby, Art Spisak, Holly Blosser Yoder

2014 ASEE North Midwest Section Conference

Recently, Honors at Iowa developed a curriculum that all student members must complete to graduate with University Honors. The curriculum has two primary components; the first is building knowledge through course work and the second is the application of knowledge through hands on learning experiences. Because, however, the engineering undergraduate curriculum is more structured and sequential in nature than the curriculum of the other undergraduate colleges, a distinct honors engineering curriculum was developed collaboratively between the College of Engineering and the University Honors Program. This engineering-specific honors curriculum maintained the key features of course work and experience-based learning valued by ...

Understanding Engineering Students' Perceptions And Knowledge About Sustainable Development And Sustainability, B. Sharma, B. Steward, S. K. Ong, F. E. Miguez

2014 ASEE North Midwest Section Conference

The Sustainable Engineering and International Development course was first offered to engineering majors at the Iowa State University (ISU) in 2005. The course is focused on describing, discussing and comparing the key concepts of sustainability, sustainable development and sustainable engineering. In 2005, sustainability was not a major part of the engineering curricula and students had little to no knowledge about these concepts. Nine years later, sustainability has become an integral part of our daily lives. In this study, we wanted to understand student perceptions, knowledge, and understanding of sustainability, sustainable development and its implementation across various engineering systems. The assessment ...
