In fact, Salomon (1993) andSchrage (1990) explicate that interactive or cooperative communities provide a richerenvironment in which to share and develop ideas and engage in learning, than do more didacticinstructional environments. When members of a classroom possess and practice all three ofHymes constructs, cooperative learning communities can exist and thrive.The task of becoming an asynchronous studentProblems.

With the explosion of Internet Access and the need to have more students to access theuniversity facilities, distance learning becomes very effective teaching tool for some engineeringsubjects. One of the difficulties of conducting distance learning of engineering courses is howstudents can conduct experiments remotely in an effective way. With new Internet DevelopmentSoftware and LabView program from National Instrument, the distance learning laboratorybecomes a reality. We will discuss the requirements on both hardware and software for distancelearning laboratory course. We will also use one project, DC Motor Speed and Torque Controlusing Single Phase Controlled Rectifier Circuit, to demonstrate that students

orperiodic table phase);(4) isolation and test of phenomena, with implied reproducibility by independent observers;(5) quantification (classical physics phase).Even the first of these is commonly acknowledged as "science" when applied to a traditional areaof study (e.g. biology). Many areas of science cannot reach the final "quantification" stage inwhich mathematical relationships are formulated. Engineering design, the process of designing,is obviously such an area, but this observation must be qualified by the connections to otherknowledge. Designing as an area of scientific investigation, codification of knowledge andtheorizing can, in parts, not even reach stage 4, because the human element is not strictlyreproducible – humans are idiosyncratic

As aresult, engineering technology programs at the two- and four-year level have added controlcourses and laboratories to prepare the graduates for the systems awaiting them in industry.Building a controls laboratory that uses standard industrial control elements is costly anddemands allocation of a large laboratory area. Traditionally, process control laboratories inschools used large system trainers to teach the control of material level, flow, temperature, andpressure. While the performance of these systems is satisfactory, problems occur when theselarge systems are used in introductory control theory laboratories. The problems include:• The high trainer cost prohibits the purchase of multiple student stations.• The small

systems [1]. The basic concepts of three-phasepower are taught to a wide variety of engineers in either a general circuits course or a classdedicated to energy conversion and power systems. The systems used as examples when teaching power systems typically involve dangerouslyhigh voltages and currents. For obvious reasons of safety and logistics, it is not practical to havestudents work with actual power systems. Power demonstration stations that allow students towork with relatively low voltages (hundreds of volts) in a laboratory setting are available. Withthese stations, students can build and experiment with motors and other three-phase loads.However, these demonstration stations are usually large (the size of a lab bench), expensive

The sand-binder mixtures selected for this study demonstrate the capability of thedeveloped tester to deal with diverse combinations. The distinctive results obtained confirm thatthe tester is a valuable tool that can aid the foundry engineer in predicting the behavior of coreand mold material in thermo-mechanical applications, thus helping in dimensional control. It isour belief that this collaboration has been a successful one based on the interest in the prototypeTDT shown by foundry practitioners and binder manufacturers.IntroductionBecause of the

Construction industry has adopted new inspection programs withseveral NDT techniques, many of which initiated in the research units of universities, and were thentransferred to the industry for use and further development. However, in most cases, they did notinfiltrate the classrooms. As a result, engineering graduates are not properly trained to utilize NDTequipments. Other countries have placed a greater emphasis on NDT in their education system [6].Similar efforts exist in the U.S., but are rare.
