Much of the content relies heavily on previous knowledge. This is wherethe students’ eportfolio or repository of information comes into its own. The basic resourcesneed for understanding the topics in second and third year MSE are grouped and available as anelectronic resource for all students to access. For example in the second and third year subjects,HES2281 and HES3281 topics associated with steels, polymers and ceramics experiments on

transition happens within a bounding temperature range.While standard tensile test as well as izod test on polymers are very useful and fundamental tomaterials testing, polymers behave in a unique fashion when pulled suddenly with an impactload, which mimics high strain rate. Impact testing explores an object's reaction to highdeformation rate or strain. An impact test is intended for determining the energy absorbed infracturing a test piece at high velocity/strain rate. There are 2 standard bending impact tests;Charpy and Izod. Figure 1 shows standard specimens for these tests. Figure 2 shows the level ofenergy absorbed by specimens of a particular material tested at different temperatures. STRIKE (a

, 2008 Writing a Book on the Role of Materials Science in Manufacturing for Instruction and Research: Lessons LearnedAbstractIn 2006, the author and two colleagues published a materials science book that tried to integratebasic elements of processing science and manufacturing technology from a materials scientist’sviewpoint. The book project essentially evolved as a scholarly experiment designed to 1) addressopportunities and challenges faced over a decade of instructing students from diverse disciplines,and 2) create a cross-over instructional resource that emphasized the solid role of materialsscience in manufacturing for use chiefly by students of engineering studying manufacturingprocesses and materials science. The goal

Figure 1. Two alternative approaches (much simplified) to the teaching of materials.Students of Engineering can find this too remote from the goals that motivate them.Engineers make and manage things. They are interested in the uses and performanceof materials. To select materials successfully, they need a perspective of the world ofmaterials plus some understanding of the origin of materials’ properties and the waysin which they can be manipulated and selected to meet the

Inertia causes the coil to continue around untilcontact is reestablished and the process repeats itself. In other words, the motor revolvescontinuously.

It iswidely held that project based learning contains two essential components: (1) a drivingquestion or problem that serves to organize and drive activities, which taken as a wholeamounts to a meaningful project; and (2) a culminating product(s) or multiple representationsas a series of artifacts, personal communications, or consequential tasks that meaningfullyaddresses the driving question.1 In this project, the students were challenged to examine aeqoogtekcnn{"cxckncdng"Ðtgcf{-to-wugÑ"eqpetgvg

The goals ofthe course are: 1. To acquaint students with the design process and the creative challenge inherent in design engineering through the medium of individual design and construction projects. 2. To provide insight into what design engineers do.The course is a two credit course that consists of a one hour lecture and a three hour laboratory.Every semester the course is given. The

In this section, an introductorypolymerization laboratory where the students polymerized Nylon 6,6 and Poly-methylmethacrylate (PMMA) is followed by five laboratories focusing on rheology, surfaceenergy, viscosity, gel permeation chromatography (GPC), and mechanical properties.Based on our extensive experience 1-3 in working in vitro with microtubules (biopolymerstructures which self-assemble from the protein tubulin) we perceived an opportunity to design anovel laboratory focused on the illustration

of Learning Gains. Preliminaryanalysis of data from the MCI for a portion of the control group shows that there are significantgains in learning even in a traditional lecture class, and that the MCI appears to have some biasagainst women.IntroductionTraditional models of teaching are focused on the delivery of content. It is assumed that learningoccurs by the instructor telling the students the information. The problem with this approach isthat it does not match with the research on learning. The well-known cognitive model oflearning, developed in the field of psychology, describes the processes by which a learneracquires new information.1 Figure 1 illustrates this model. The key point to note in this model isthat information is actively
