Assessment has been done through the use of pre- and post-tutorial quizzes, studentopinion surveys, and demographic surveys of student learning styles. Furthermore, theimplementation of a design project that involves an application of the knowledge gained from thetutorials is also discussed.Introduction The finite element (FE) method is a widely used tool in industry for analyzing engineering problems. The most basic FE theory and applications are offered primarily as a graduate- level course, or in some cases, as an upper-level

The catapult arm, withattached strain gages, will be loaded with a known force, and the strain recorded. From this dataset of static loading, we will determine a modulus of elasticity for the wood, which may be afunction of the load.  Figure 5. Initial Strain Gage Setup.

We place six teachingbenches with two set of experimental setups, as shown in the Fig. 2 below. The students will bein two groups (group A and group B) and switch experiments every two weeks.The following objectives were achieved with the laboratory expansion and upgrade: 1. Increase enrollment from 9 to 18 students per laboratory section. It is estimated that the EE department’s $60k expansion cost will be repaid in less than 3 years by reducing teaching hour demands for the course. 2.

By taking the device apart the students can see the role of each sub-part and how it interacts with the other components. Functional Analysis helps students to transfer their understanding to other devices that utilize similar elements or core technologies. b) Labs should be done individually. Each student
