This approach enables academic programs with limited funding toprovide a valuable hands-on experience in factory automation to students while they are inschool, rather than leaving it to be learned in the workplace. Two examples of laboratory projectsinvolving high and low degrees of hard

Each of the reverseosmosis units are compared to each other and to other water filtration techniques.The goal of this laboratory experiment is: · To introduce students to the RO technology · To familiarize them with the advantages and disadvantages of different size units, and to · Perform basic RO calculations in a real world application.Also, longer term experiments can be performed to demonstrate how efficiency reduces overtime, and TDS increases in the permeate stream to if the reverse osmosis units are not changed

A major task to develop a new teaching laboratory for the Electrical andElectronic Systems (EES) was undertaken during Spring 2000. This laboratory is used by fourcourses in the Electrical and Electronic Systems area: Circuit Analysis, Electronics, Sensors andTransducers and Motors and Power Distribution. Each of these courses has a laboratorycomponent. The

Figure 9Capture of switching transientsNewer power quality meters offer the student the opportunity to observe transient phenomena inaddition to harmonic analysis. Probably the most common power quality disturbance is the high-frequency ringing surge or transient that can occur with capacitor switching, lightning strikes, ortransmission line switching. Such a transient can easily be observed in the laboratory and byrepetitive operation, the student can observe how the transient varies with the time of the eventon the voltage waveform. Figure 10

These courses aremainly designed to compliment and enhance the traditional method of education in general andto provide students with a new and flexible method of learning in particular. The fact that theInternet/Web is currently being utilized extensively in distance-learning1 shows that educationalorganizations have made a strong commitment to distance learning through Internet and WorldWide Web.

experimentation, and finally, concrete experience(feeling). We believe students learn better when "hands-on" applications (activeexperimentation) are presented concurrently with classroom theory. Traditionally, students oftenwait between 1– 2 years to apply previously learned theory to an actual application in anexperimental laboratory setting. At the University of Kentucky, we offer an undergraduatecourse in the Chemical & Materials Engineering curriculum called "Heat and Mass Transfer".Recently, our department has been making a concerted effort to bring more experimentalapplications back into the classroom. One such experiment we are incorporating into theclassroom environment is the study of heat and mass transfer and how it applies to such a

Additionally, “class” means the face-to-face timespent with the teacher in charge.

Links to additional practice problems were provided for students whodid poorly on the tests. (We know of several faculty members who provide links to on-linecopies of their final exams.) Further assessment was conducted using standard testing proceduresin the classroom. In two other courses, we provided rubrics for assessing laboratory reports andtechnical reports.Evaluation from the instructional designer's perspective generally refers to evaluation of theinstruction (formative and summative). Formative evaluation is much more prevalent in trainingthan in education and often includes
