alloys and a number of high performance carbon reinforced composites. Farag (2002)has listed some of the general (not specific to connecting rod) material performance requirementsand has related possible modes of failure with the material properties. He states that thecatastrophic fracture due to impact loading is resisted by the high fracture toughness, which is arigid material requirement and should be used for initial screening of materials. He also statesthat the local and the global buckling are resisted by high elastic modulus, and is a soft materialrequirement.Ashby, Shercliff and Cebon (2008) have looked at the shaping of a steel connecting rod and havearrived at the short list of processes as (a) die casting, (b) forging and machining

into curriculum. At this point in the discussion, manymainstream faculty metaphorically throw their hands up and say, “I do not have the time tochange everything, including all of my teaching and testing methods.” We claim that eachprofessor does not have to re-invent the wheel. In fact, by a limited literature search many topicsnow have active learning templates that are easy to follow and integrate.Two diverse student populations from two geographically distant campuses were surveyed.Faculty from two different universities, a mid-size HBCU population, University A and a largestate school, University B, implemented the following three easy-to-employ active learningtechniques: 1) Process Oriented class worksheets, 2) Concept-in-Context

Central Washington University (CWU)AbstractOur traditional casting course features both lecture and laboratory venues. However it is notedthat many students have never interacted with foundry equipment, and there is a significantlearning curve associated with the ability of a student to execute basic green sand foundryoperations.
