students. To accomplishthis, the team partitioned the initial concept of one learning module into the development of twolearning modules: (1) a tutorial learning module that will provide the student with foundationalknowledge of PCB technology and the resources available on the web, and with a proceduraltemplate for developing a PCB board; and (2) a laboratory learning module designed to replacetwo standard experiments on operational amplifiers (op-amps) which we believe are taken by allengineering students in the lower division.The development of each of the learning modules will be discussed below. The plan is tointegrate these learning modules into the lower division electrical engineering service coursetaken by all engineering majors. The

others appeared to be transcribed “after the fact”. We attempted to address these issues by evaluating each student’s lab notebook tear-out sheets several times throughout the semester (on a total of four different occasions). While this rather significant effort on the our part lead to notable improvements in the lab notebooks relative to previous offerings, there is still room for improvement especially for team members charged with software development, who generally kept the “worst” notebooks. The fundamental problem appears to be getting students to: (a) appreciate the value of a good lab notebook, and (b) take it seriously.1

This programmability allows the user tochange functionality an unlimited number of times to fit the desired application. For theMicroprocessors course, the FPGA is used to instantiate a soft-core processor.The Altera DE2 (Figure 1) was selected as the FPGA development board for updating theMicroprocessors course. With a complete set of tools, a large selection of standard devices, andthe ability to be reconfigured, the Altera DE2 has all the features necessary for prototyping andaddressing numerous protocols. The Altera DE2 integrates industry-standard development anddebugging tools (Eclipse IDE, GCC compiler and GDB debugger) that the

It could also be seen that the students’ interest in the course improved.1. OverviewComputer System Architecture, [1] written by M. Morris Mano, has been the most widely usedteaching material for training and understanding computer operation since its publication. Thisteaching material provides an understanding of computer operation, assembly language andassemblers, and enhances ability in hardware design and software programming.However, it is very difficult for students to learn this subject through theoretical lectures

activitiesconsidered to be important contributors to student retention. Swail2 also notes thatresearch opportunities are very beneficial to science and engineering students. Studyingreal-world applications of classroom concepts improves the student’s educationalexperience and preparedness for the job market. Faculty-student contact beyond theclassroom is also cited as helping to build student motivation and providing positivefuture impact on educational and career decisions2. Grabowski3 also identifies successfactors in undergraduate research that include 1) cross-disciplinary projects, 2) value bothto students and to faculty, 3) close faculty mentoring, and 4) authentic rather thanexperiential activities.

. This is especially important when learningprogramming. However learning PLC programming is different from learning general purposeprogramming because equipment interfacing and control is involved.Unfortunately, educational institutions often lack the resources needed to help students tobecome proficient with PLC programming. For example, a Manufacturing Automation andRobotics course typically uses programmable logic controllers, sensors, robots, and machinevision systems in teaching automated manufacturing system design. However, students’ learningis hindered by obstacles such as:• High faculty-to-student ratios: For example, the ratio for Manufacturing Automation and Robotics at one major university is 1:36 for lectures and 1:18 for each

conceptualthreads from the required curriculum and strengthens their DSP programming skills with a seriesof mini-projects1.The choice of computational platform for mini-projects and in-class demonstrations is a keydesign decision for the course. Richard Hamming once said “the purpose of computing is insight,not numbers,” and students gain manifold insights when they interact with a signal processingsystem of their own creation. The choice of a development environment for optimum studentlearning revolves around two critical issues: (1) the total time required to transform a conceptinto a working system, and (2) the degree to which the system is interactive. Frustration resultswhen the development process takes too long or is too complicated. In addition

Introduction“We need to work to support ourselves and we want a life, therefore time for study is scarce”depicts the typical full-time student characteristics in ACU, Australia. Part-time students, withages varying between 25 and 50, have one or more of the following responsibilities: • a demanding job; • family; and • the need to improve their career potential.The scarcity of time for study is witnessed by the aforementioned student characterization and assuch, it is desirable to design courses which

The overall length of the antenna is about 5 feet long. Whilethe antenna was designed by electronic and computer engineering technology (ECET)students, mechanical engineering technology (MET) students took charge of building itunder the supervision of their MET instructor. The structure was built by spot weldinglaser-cut pieces of sheet metal. ECET students made experimental measurements toverify the predicted gain and functionality.Motivation:The design of the large Cantenna (Figure 1) was taken up by students as a classproject for the Communication Circuit Design (ECET 420) course.

The paper discusses virtualinstrumentation-based interfaces for real-time control and display of electric machinedrives. This approach will lead to the flexibility of applying this setup as a platform tostudy electric drives as well as the LabVIEW-based (from National Instruments, Inc.)experimentation design.In this lab, the machine drive is implemented using a distributed real-time simulationsystem from Opal-RT 1 with machines and power electronics drive board as hardware-in-the-loop (HIL).

Examples of these include texts on general circuit analysis 1, generalelectronics 2,3, communication systems 4,5, power electronics 6, and photovoltaic systems 7.There are also textbooks intended as primers or introductions to PSpice itself 8,9,10,11. Publishersoften support web sites that provide worked-out examples from the textbooks.However, it is often easier to create one’s own additional PSpice examples rather than to siftthrough the mountain of available resources. This was the genesis of the PSpice Archive of theUniversity of Texas at Tyler. The collection began as an ad hoc effort to

Many of the modules can also be runcompletely on the host computer's sound card. Modules have been developed for examiningdifferent aspects of topics such as sampling, aliasing, and filtering, while working with data thathas been captured and processed in real-time. Students are able to interact with the hardware anddata through GUIs, thus obviating the need to first develop real-time programming skills. Thispaper will describe these modules and how they are designed to be used both in lectures and aspart of homework assignments.1. IntroductionRecent advances in embedded

, there seemed to be a huge disconnect. There was noticeable knowledge lossover the summer break. It is well documented that knowledge retention decays over time9.Therefore, in the feedback discussions, faculty brainstormed ideas for refreshing the memories ofthe junior level students. The first key change at the course level of the junior microelectronicswas the requirement of summer homework. It was believed that students who did their summerhomework, would have better knowledge retention. Thus, over the summer, students wererequired to do homework problems similar to those shown in Figure 1 and to bring thoseproblems with them to the first class of the microelectronics course.
