Three screensdisplay the content and instructor views at the front of the room and the distant students at theback of the room, as shown in figure 1. The instructor controls the camera views and contentimages from a control panel at the front of the room. A Blackboard website supports the course.The content storage tools for keeping the syllabus and course notes, the gradebook function,assessment and survey tools, and occasionally bulletin board and chat room features inBlackboard are used to enhance the in-class instruction.

solve future problems of a similar type. By recreating and inventing some simpleengineering problems that can be solved using models, instructors can introduce students to thisprocess to prepare for professional practice.Model Eliciting Activities (MEAs) are a way to make students think critically about open-endedproblems. To ensure that new MEAs are held to a high standard they are subject to six basicprinciples: model construction, reality, generalizability, self-assessment, model documentation,and effective prototype. 1.) Model Construction: Requires the development of a model or decision algorithm. 2.) Reality: It must be set to a relevant engineering application. 3.) Generalizability: The resulting model should apply to other similar

This paper will organize some of the best practices insports coaching and draw parallels that will enhance student learning in project based instruction. Thepaper discusses the parallels between the instructor and the coach and highlights three broad categoriesof techniques: 1) Practice and games, 2) Teamwork and individual performance, and 3) Individualfeedback for improvement. Some of these techniques have been used to successfully enhance learning ina senior design course in Industrial Engineering at Cal Poly. The insights in this article will open up arich area of

Figure 2 depicts an SDR system. In this case,the receiver front-end is merely a filter and gain stage while the software in the host computerreplaces the balance of the receiver after analog to digital conversion. As outlined in Figure 3,the USRP provides the analog to digital conversion and frequency down conversion. Figure 1.

Multidisciplinary Design Optimisation (MDO) is a very useful technique for solvingany multi-body dynamics problem [20]. MDO is a body of methods and techniques forperforming the optimization so as to balance the design considerations at the system and detaillevels.

Completed bridges are loaded until failure.Rules and Specifications:1. The bridge is to be built solely from spaghetti and five minute epoxy. Per three or four person team, the two bridges are to be as identical as possible with the ONLY exception being that one bridge can have epoxy at any location and the other bridge can only have epoxy up to 1.5 cm in any direction from the node. Disqualification will result if this is violated.2. The bridge shall be free-standing and must span two level surfaces which

The motor is attached to the free end of a light carbon rod, while the other end of the rodis connected to the shaft of a low-friction potentiometer. The potentiometer is fixed on a plasticstand at the proper height, so that the pendulum can swing freely (see Fig. 1).

The teams then apply basic aircraftparameters in order to calculate and verify the total aircraft performance. In the aerodynamics portion ofthe course, the teams research the airfoil that makes up the wing of their selected aircraft.
