In the seniorcourse the satisfactory completion of a project proposed by a “client” (industry orfaculty) is the primary focus of the assessment process. Approximately 80% of theindividual course grade is associated with the project, but not all students on a given teamreceive the same grade for their team project since some of the activities associated withthe team project are assigned directly to individuals for which they receive individualgrades.

First, it wasdecided that the module should focus on one type of smart actuator, the piezoactuator. Thepiezoactuator was chosen because the collaborators had extensive experience with modelingand control of piezoactuators in their own research9. Future work will focus on developingmodules for other smart actuators, such as shape

As such, if one is able to see the satellite at 23,000miles from any location on earth, it will appear to be a standstill object. Types of Satellites: There are three basic types of satellites:1 Geostationary Earth Orbit (GEO) Satellite2 Medium Earth Orbit (MEO) Satellite3 Low Earth Orbit (LEO) Satellite The GEO satellite is the furthest from Earth, located at 35,786 km or 22,300 miles in orbit. A GEO satellite is geostationary in that it rotates at the same speed as the Earth. At that elevation, only a few GEOs are needed to scan the entire globe. Because of their high altitudes

Efforts to improve the curricula and practices of engineering education include morecollaborative and socially based pedagogies (e.g., design thinking, problem-based learning, andcooperative learning), as well as more experiences based in the workplace, e.g., ABET’sprofessional skills and the attributes of the Engineer of 20204, 5, 6.These efforts haverecommended significant revisions to engineering curricula by expanding the content ofengineering from its traditional focus on the application of math and science to broader, sociallyand design-based curricula.

At least one student voiced concern about using the rubric for evaluation purposes, particularly if the scores are peer assessments. We have not yet used the peer rubric scores when considering final grades (although we have used the project advisor rubric scores). When the rubric was designed, we thought of it being most useful in two ways: (1) as a formative assessment and instructional tool, clearly spelling out the characteristics and attributes that were important

Since 2000, the requirement to include ethics as partof an accredited degree has crystallized.1 However, now that more engineering curricula aretaking ethics seriously, the question of what rightly belongs in an engineer’s ethics education isdeservedly garnering more attention.
