performed are second semester junior year and either semester senior year. The students are first given lectures on fracture mechanics, metals, alloys, and composites. They should have already had a laboratory experiment on metallography and sample preparation. A video on the deterioration of restorative materials in the oral environment is used as a backdrop for the experiments. Objectives The objectives of these experiments are to show that the area of biomaterials, especially dental materials (natural and synthetic), contain all of the elements of good and bad design, with the caveat that a person’s health is directly involved. The students learn the
of the materials-related emphasis of the curriculum of theDepartment of Mechanical Engineering at Northern Illinois University. These courses are offered eachsemester and average 30 students per semester. Until recently, none of these courses included a laboratory inwhich students could gain direct, hands-on experience into the behavior of materials. The lack of anundergraduate laboratory specifically focused on introducing the undergraduate mechanical engineeringstudent to the world of materials was viewed as a weakness in our curriculum by the author. Moreover, in theopinion of industry, there is an immediate need for engineers conversant in the fundamental principles ofmaterial behavior best reinforced by direct, hands-on laboratory
Session 1626 Implementing A Sophomore-Level Materials, Manufacturing & Design Laboratory Edmund Tsang and Andrew Wilhelm Mechanical Engineering Department, University of South Alabama, Mobile, Alabama 36688ABSTRACT A one-credit hour, sophomore-level laboratory course was implemented in Fall Quarter, 1995 tointegrate materials, manufacturing and design. The course meets once a week for three hours, and is team-taught by two faculty members, one with background in materials science and the other with background inmanufacturing and design. Course activities aim to create a discovery-oriented learning

duringthe process of idealization?” Recently, this pedagogy has also been int.mchmd into engineering courses. Regan et al. [6]described four laboratory experiments using edible materials. In an attempt to construct an efficient curriculum, Giorgetti[7] combined theory and laboratory experiment into a single course on fluid mechanics. Dvorak [8] discussed integrationof a simple experiment in heat transfer with analytical solution and computer simulation. More nxentl y, authors of thispaper presented a new teaching methodology using home experiments [9]. Our approach integrates simple homeexperiments with lecture courses to develop interes~ understanding and appreciation for theory. In this paper fourteenhome experiments that can be readily adopted
Session 3268 Integration of Manufacturing Design Applications in FE–Based Applied Mechanics Courses Mansur Rastani North Carolina A&T State UniversityABSTRACT Many mechanical engineering disciplines are implementing numerical methods of designingmechanical and or structural components within junior or senior–level courses utilizing a technique such as finiteelement analysis (FEA). However, the classical examples and case problems studied in these courses do notusually provide the students
explore methods of implementing cooperative learning ina large-enrollment, sophomore-level basic mechanics course. Time in class- was generally allocated as follows:questions on past homework, 5 minutes; lecture on new material, 10 minutes; example problem, 15 minutes; andcollaborative group quiz, 20 minutes. To facilitate this schedule, brief lecture summaries and group quizzes weredeveloped for each class period. Lecture summaries minimize the time students need to copy class notes andpermit the instructor to focus attention on known areas of weakness. Group quizzes allow students to “actively”reinforce the material presented so that they can identify any “gaps” in their understanding and seek immediateassistance from group members and/or the

anticipated that upperclassmajors in electrical engineering, mechanical engineering and in chemistry and physics will find the coursecontent complementary to their required core curricula.Anticipated BenefitsIt is anticipated that the two-quarter course sequence described here will enhance significantly the exposure ofundergraduate students to important areas within the field of materials processing. The concurrent exposureto research results and industrial practice in the five areas cited is expected to spawn increased student interestin this important area of materials technology. Thus, potential for career paths in materials processing shouldincrease - consistent with the manpower needs identified in the NRC report (1).Exporting the CoursesA

ways concept maps can be usedin the mechanical engineering curriculum. They can be used to help students understand the structure of thecurriculum, the relationship between courses, and the material within a course. The reaction of students to theuse of concept maps has been enthusiastically positive. Introduction The process for obtaining higher levels of learning is the same for any discipline 1. The phases of alearning hierarchy are shown in Figure 1. A student must first learn the terminology and facts which make upthe basic language of a discipline. After learning the facts and terminology the student is able to combine themto understand concepts. The more concepts a student possesses
design experience is developed and integrated throughout the curriculum"1. A new curriculum, which provides greater flexibility to upper division students to meet their diverseinterests and which enhances the design experience for lower division students, was implemented in Fall,1995 as a result of that effort. A new, four-credit hour "Introduction to Mechanical Engineering" replaced aone-credit hour course in the old curriculum so substantial design and curriculum integration can beimplemented; this course was taught for the first time in Winter Quarter, 1996. Other lower-divisioncurriculum ehancements include three new courses: (a) a one-credit hour, sophomore-level laboratory courseintegrating materials, manufacturing and design was

Analysis was to be done with concepts learned in mechanics of materials courses.Numerical analysis approaches were optional. Various plastics design texts were assigned [2,3]. Students wereencouraged to also refer to design manuals [4,5]. To simplify the analysis, the plastic was treated as a linearelastic material below the yield stress. Design optimization of was not expected or required. Experience
