satisfaction. CPI is one of the results of applicationof statistical process control, which originated in Bell Telephone Laboratories in 1924 byDr. Walter Shewhart1. ABET evaluation criteria espoused application of continuousimprovement philosophies to Engineering Education with the Engineering Criteria 2000published in 19962 and continue to propagate the application with the current standards3.The practice has become so ingrained in American industry that in May 2006, all USDepartment of Defense (DoD) activities were required to implement CPI and theContinuous Process Improvement Transformation Guidebook was published4. Thepersonnel conducting this study were trained in CPI through DoD activities and broughtthat experience into the educational

all students to completely work all the emporiumassignment problems, students are given an opportunity to return later in the same or the nextday to complete the unfinished problems in what we call post-emporium sessions.2. Encourage Active LearningActivities in the emporium focus principally on solving problems towards deeper understandingof the course contents. Students work assignment problems on paper and submit their resultsonline for a prompt feedback. While the same set of problems is assigned to all students, thenumbers in each problem are algorithmically assigned (different) to encourage students to workon their own problems, although peer interaction is allowed and indeed encouraged.Hands-on laboratory activities with physical

numerical methods werecompared with the corresponding closed form solutions.INTRODUCTIONThis study constitutes a laboratory component of the strength of materials courses taught to bothengineering and engineering technology students. It is important that engineering students learnthe detrimental effects of stress raisers such as notches, holes, and sharp corners in machinemembers. Such discontinuities can cause a large rise in stress above the nominal value. Thistopic is introduced in the strength of materials course in the design of a stepped shaft withkeyways subjected to bending, torsion, as well as axial loads. The nominal axial stress, thebending stress, and the shear stress due to torsion in the shaft are each multiplied by thecorresponding

quiz require the student to consider a concept in connection with a situation reflective ofactual practice so that the relevant concepts allow solution of real problems. Page 15.1007.7Group problems – In engineering school, we learn in much the same way that we practice aftergraduation, in groups. In study groups and laboratory work, students don’t learn in isolation.Group learning exposes students to a variety of individuals and viewpoints, and enables them toask questions in a relatively safe environment. A small group in the classroom is one form of a“circle of trust.” [10] In the revised statics course, students usually are asked to

Page 15.1331.3ball [31. A frame-by-frame study of the pictures of bouncing tennis balls obtained using high-speedcameras (2000 frames per second) in our laboratory demonstrated that this process consists of fourseparate and distinct phases: initial contact, deformation of the original shape, restitution andrecovery of the shape of the ball, and separation and takeoff.Phase 1: Contact. Initial contact between the ball and the surface occurs at one point.Phase 2: Deformation. Although the lowest point on the ball has been forced to stop movingduring initial contact, other parts of the ball continue to move downward. Consequently, a periodof continued contact is observed during which the ball is in contact with the surface over an areathat
