Outline l l l Design Context Senior Design Options Sample Projects Self-Evaluation Panel Discussion

Definition – Senior Design Course A Senior Design Course must provide students with a major multi-disciplinary design experience based on the knowledge and skills acquired in earlier course work. The design project must be team-based and must incorporate engineering design standards and realistic constraints that include most of the following considerations: economic; environmental; sustainability; manufacturability; ethical; health and safety; social; and political. The experience must also reinforce the students’ understanding of ethical and professional responsibility and their ability to communicate effectively.

Definition – Major Design Experience A major design experience is one that involves at least three (3) credit hours of coursework with 100% engineering design content and involves most of the following elements of the design process: l the establishment of objectives and criteria l synthesis l analysis l construction l testing l evaluation

Senior Design Learning Outcomes A student who successfully fulfills the course requirements will have demonstrated: 1. an ability to apply knowledge obtained in earlier coursework and to obtain new knowledge necessary to design and test a system, component, or process to meet desired needs. 2. an understanding of the engineering design process. 3. an ability to function on an interdisciplinary team. 4. an awareness of professional and ethical responsibility. 5. effective communication skills, both oral and written. 6. Successful demonstration of all five learning outcomes is required to receive a passing grade.
