Z-FE C-AL C-FE -0.005 T i me ( s) Figure 4: Thermal Distortion CurvesClosing RemarksThe proposed apparatus and protocol provide the foundry engineer with a process control toolthat generates data that more closely represents the thermo-mechanical behavior of a sand/bindersystem during the metal casting process. Recalling that we are pursuing near-net shapes, the dataprovided by the developed apparatus will allow the practitioner to qualitatively – at this point –compare expected performance of the cores/molds.There have been great experiences provided by this project to several capstone design groups.The students have benefited from the
faculty toinnovate techniques at low-cost or no-cost basis.At KSU-S, the MET program offers both the associate and bachelor degrees. These programs arebased on 2 + 2 concept. Students enroll in associate programs and after completion, somecontinue in the bachelors program. The MET program has a heavy emphasis on hands-onexperience integrated into several courses. Our current MET program provides a mix of designand manufacturing related courses. The footstone project is introduced in MET 117 MechanicalDetailing and MET 125 Computer Numerical Control (CNC) Machine Processes. The project isa common assignment in both courses. These are offered as freshman second semester courses inthe associates program. During the first semester students acquire
is apparent that instructional goals for students to be lifelong learnersequipped with science literacy, information fluency and communication skill are met bystudents learning experiences.The cross-curricular endeavors have amplified teaching effectiveness of each unit andhave strengthened the collegial communication. The collaborators have learned fromeach other’s reflections to make the assignment a meaningful learning experience notonly for students but also for themselves. With respect and understanding for eachother’s role in student learning, the collaborators demonstrate their ability to engage inlifelong learning and foster students to be lifelong learners.1 Elmborg J.; Hook S.

ofinformation. Within the educational community, the web is increasingly used both as a learningtool to support formal training and as a means of delivering online learning. The main objectiveof any educational program is to disseminate knowledge and it remains constant throughout thecycle, whereas the delivery system changes with respect to time. The modern developments inInternet started with Arpanet. In the early part of the 90’s, Gophers, a menu based informationsystem with “text only version” was introduced. Later, Mosaic was evolved as a viableinformation system with both text and a graphics version. The technology has exponentiallygrown into the modern Netscape, Internet Explorer and other search engines. Web-BasedInstructional tools have been

Portfolio Assignment: Scientific Paper AnalysisStudents were instructed to select an article on a current biotechnology topic thatinterested them from a secondary source (newspaper, popular magazine, website, etc).Then, find the original sources cited in the paper, examine the primary source(s), andcompare to the secondary article. In addition, the students were instructed to consider thefollowing questions in their report: • Why did you select the original article—what piqued your interest? • What is the relevant background information & the

cohort of students don’t miss out on important concepts thatthey will need in later courses. In the previous curriculum, adjustment to fall courses would havebeen made for future students, but without the studio courses it was more difficult to addressweaknesses for the students that had already completed that semester.We expect that many challenges, both known and unknown, will need to be worked through. Weplan to collect data and document the implementation to produce a four-year longitudinal studyof this new curriculum. Our hope is that others contemplating similar curriculum revisions canbenefit from what is presented here in this paper and may have suggestions for implementationof this curriculum.References 1.

But in theworkforce, graduates will need to understand how to choose a given motor for a particularapplication. This means answering questions such as: Which type of motor is the most appropriate for the given application? At what speed(s) should be motor be operating? What torque is required for the application? What environmental issues need to be considered in selecting the motor?An initial foray into motor selection was briefly discussed as part of a larger discussion involvingworking with industrial partners [10].
