scanners, barcode decoders, and network controllers (see Figure 1). The networkcontroller controls up to two networks of 31 barcode decoders. Each of the 31 barcode decoderscan control two handheld barcode scanners. This means that up to 124 handheld scanners can becontrolled by one network controller. Figure 1. Barcode Network StructureAs a barcode is scanned by the handheld scanners, the data is transmitted from the scanner to thedecoder. The barcode decoder interprets the barcode signal and stores it in local memory. Thedata remains in the decoder module until the network controller polls that decoder. When the Page

We askedthem to select and rank the top three instructor characteristics they believe to be the mostimportant for improving student learning. The ten characteristics they were asked to chose fromare shown in Table 1 (plus an option to suggest additional items). These ten items were chosenafter reviewing current literature on effective teaching (e.g., Wankat & Oreovicz, 1993; Prichard& Sawyer, 1994) and student academic success. Data were collected over a period of 18 months(from Spring semester, 1998, to Fall semester, 1999). (While the order of items in the actualsurveys were varied randomly over the course of the data collection, all data are reported usingthe

The goal is to form Engineers with good skills more creative, more critics and moreattempt to the quick transformations in every aspect of professional life integrated to the newconnected and global world. This experience has showed good results and has also brought upthe changes in the way of seeing the Engineer as an agent of Science and Technologydevelopment for the well fare of humanity.I.

join the workforce.In order to address the increasing demand for a skilled workforce, a process was needed for thedevelopment and dissemination of a technology-based education curriculum that is both readilyaccessible and responsive to innovation and industry needs. As a result, a coalition of five two-year technical colleges in Tennessee with representatives from four-year universities, secondaryschools, business and industry, and government institutions in Tennessee, Kentucky, andAlabama was formed (Figure 1). A grant proposal titled “The South-East AdvancedTechnological Education Consortium, SEATEC” was submitted to NSF for funding. The grantwas funded for three years with the following goals:1. To provide national leadership for the
groups by age/grade level. All activities could be completed ina one-hour to one and one half-hour period. The activities were selected so as to challenge, butnot discourage, children at a particular level and also to expose to them to an engineeringconcept through a hands-on activity. Background for the engineering concepts was presented atthe start of each activity. Activities were also selected which required the students to worktogether in teams.Activities In the youngest age group (kindergarten and 1st graders), students worked in teams ofthree. Three activities were conducted with this age group: the egg-drop competition [1], strawtowers [1], and aluminum foil boats [1] . The egg-drop competition has been used at a variety
dilemmas are non-existent and that the means-end principle and utilitarian principle willdominate ethical considerations. Second, the Bounded Rationality model tends to be less idealistic, and to consider thelimitations of day-to-day decision-making. It reflects individual tendencies to conduct limitedsearches for alternatives, to make choices under situations of inadequate information or control,and to (satisfice) select the less than best solution. Satisficing is the practice of selecting anacceptable goal, which might be easier to identify, less controversial, and otherwise safer thanthe best possible solution, very often, the manager's view of being reasonable to achieve. Thebounded rationality process reflects the human tendencies to 1
University offers a Masters ofEngineering Management (MEM) degree as its core product. In the fall of 1998 the faculty recognizedthat the MEM curriculum should be examined to ensure relevancy to existing conditions. Industrial basechanges in the southeast Virginia region, faculty personnel turnover, administrative pressures toincrease enrollment, and other environmental changes highlighted the need to critically examine theMEM curriculum.The curriculum redesign effort adopted an outcomes based methodology in which the curricular topicswere to be directly tied to desired outcomes. Through a series of facilitated meetings the facultydeveloped MEM program objectives and associated goals. These are summarized in Table 1-ProgramObjectives and Goals
that immobilizes whole mechanism is equal to its mobility.The Gruebler’s and Kutzbach’s formulas for the mobility of a plane mechanism and found inmajority of textbooks on kinematics, [1], [2], [3], although they are known to producemisleading results.The second task of the designer is to formulate geometric conditions (parallel axes, tighttolerances on some dimensions, etc.) to make assembly possible. The geometric conditionsimposed in this stage on the links of the mechanism are also known as the redundantconstraints. An example of a system with redundant constraints is a four-leg table placed on awarped floor. To avoid shaking of the table one of its legs must have a strictly defined length.Unfortunately, parts are machined with errors. If
].Fundamental Cognitive Capacities According to Bandura human cognitive capacities that can predict individual’sperformance include ability to use symbols, learning through observation, planning, self-regulation, and self-reflection [1]. A brief description of each of these human cognitivecapacities follows. Ability to Use Symbols. By the use of symbols, humans transform immediate visualexperiences into internal cognitive models that in turn serve as guides for their actions. Throughsymbolizing, people also ascribe meaning, form and duration to their past experiences. Learning Through Observations. Learning can also occur indirectly by observing otherpeople’s behavior and its outcomes. Individuals’ capacity to learn by observation
Internet domain (TCP/IP and UDP/IP), and the Xerox NS domain communicationprotocols [1]. The socket API enables students to learn about the socket system calls, the socketaddress structure, potential byte order differences between architectures and protocols, and the byte-stream oriented nature of TCP and how to deal with it in their applications. Much of this is hiddenfrom view as a result of the abstraction provided by Java’s java.net package. While this would be aplus in developing substantial distributed systems it takes away information which is important inthe context of a Data Communications course.Simulations have been shown to be useful in the academic environment [2,3] and allow students tocomprehend networks at a deeper level than is
the community service program in which the participants areenrolled; and includes structured times for the students and participants to reflect on the serviceexperience. 1”The technical definition of Service Learning as an Instructional Method according to the Codeof Federal Regulations is a methodology:i. under which students learn and develop through active participation in thoughtfully organized service experiences that meet actual community needs and that are coordinated in collaboration with school and community;ii. that is integrated into the students academic curriculum or provides structured time for a student to think, talk, or write about what the students did or saw during the actual service activity
which students engage inactivities that address human and community needs together with structuredopportunities intentionally designed to promote student learning and development” [1].These structured activities must provide opportunities for students to reflect on meaningand significance of the service-learning projects they have undertaken. It is alsoimportant that in doing so they take into consideration the perspectives of those forwhom they have provided service.While relatively new in engineering, service-learning is well established in thehumanities and social science disciplines, and in disciplines where clinical experienceforms part of student learning.

examples of how to incorporate service-learning into a variety of engineering courses. Page 5.543.1What is service-learning?Service-learning has been defined as “a form of experiential education in which students engagein activities that address human and community needs together with structured opportunitiesintentionally designed to promote student learning and development. Reciprocity and reflectionare key concepts of service-learning.” 1 Service-learning has a two-fold focus: learning for thestudent and service to the community.In engineering terms, service-learning is akin to a design problem: integrate the subject matter ofa credit-bearing

Thus, in an integratedassessment plan course level assessments should feed into the overall programassessment.The faculty and administration of the engineering programs at Saginaw Valley StateUniversity (SVSU) have developed a Manual of Assessment4 as the initial step inimplementing a suitable departmental assessment program. This manual lists sixMechanical Engineering Program Objectives that are linked to and measured by twelveProgram Outcomes. Six different methods to assess these twelve outcomes are describedin the manual and are listed in Table 1 below. These six methods are representative ofapproaches to program assessment that are being used at a number of

solve for theunknown displacements at each of the nodes. They then solve this system of equations using anumerical method which is efficient for large numbers of equations. All of this they do with aninexpensive scientific calculator. As the final step they calculate the stress in each structuralmember.1. IntroductionFinite element analysis (FEA) software can produce color stress contour plots representing thestress at thousands of points within a machine part with dozens of forces applied. A studentstudying stress analysis for the first time can beneficially be exposed to the terminology andprogression of calculations used to calculate the stresses in the elements of an FEA model.Terms involved in FEA analysis include: nodes, local and global
Session 2793 Simple way of teaching transistor amplifiers Bogdan M. Wilamowski University of WyomingAbstract For small signal analysis a simple change from commonly used tranconductance gm totransresistance rm=1/gm leads to a significant simplification of all equations. Moreover theseequations are much easier to memorize since they have a form of resistor ratio for CE (CS) andCB (CG) configurations and the form or resistor divider for CC (CD) configuration. With presented approach most of students are able to read diagrams and to understand theeffect of each

The entire program is based on an industrial model and has threeconverging goals: 1. create a team-building environment 2. develop a unique prototype using the team 3. teach the principles of good software engineering practicesCreating a Team-Building Environment:The individual teams were chosen at random. In an industrial setting, team members generally do Page 5.548.2not have the opportunity to choose the members of their teams and the random selection processused in the class better simulates what happens in industry and eliminates having friends workingwith friends. Each team had to organize
embraced "Service-Learning"2-5. Integration of"Service-Learning" within academic disciplines that emphasize on "technical" and "scientific"skills such as Engineering and Physics are rare. References 6-8 are among the very few reportedendeavors. The emerging trends in "outcome" based engineering education facilitated byEngineering Criteria 2000 (EC2000) developed by the Accreditation Board of Engineering andTechnology (ABET) demands a holistic blend of "soft" and "technical" skills. It also calls for asynchronized effort among faculty, staff and administration to incorporate a continuousimprovement cycle in academia. Figure 1 shows the " Continuous Improvement Cycle in EC2000 ". As illustrated in the figure, EC2000 consists of two loops. The first

The partners are given 2 weeks to complete programming assignments 2 through 5. For the design projects the partners are given 4 weeks from assignment to completion. While ashared report is expected for the first design report, the report for the final project must becompleted on an individual basis.III.

Some of the laboratory exercises requiredthe students to construct their own circuit element.The following experiment description is an example:EE 211 Lab Exercise 7February 5, 1999The sketch below shows a cross-sectional view of a simple transformer. In this lab you willconstruct a simple transformer from: 1) a two inch length of 1/2 inch plastic pipe; 2) two 1/2inch plastic pipe unions for the ends; 3) 45 ft. of #28 AWG magnet wire; 4) 15 ft. of #28AWG magnet wire; 5) a two inch length of steel rod. Superglue and sandpaper will be used inthe construction process.First, use superglue to glue the unions onto the ends of the plastic pipe. This will provide a formon

Page 5.552.1tools often operate on several different platforms such as UNIX, DOS, Windows 95, WindowsNT, or on Macintosh. Another limitation is that the required design software must be installedand a license purchased for each computer where software is used. Only one user interfacehandled by a network browser would be required [1]. Furthermore instead of purchasing thesoftware license for each computer EDA tools can be used on a pay per use basis. Similar trendexists in electronic publishing where the reader pays per access to the material instead ofpurchasing journals, books, or abstracts.II.

Below are included specificactivities with comments and suggestions for the first week.(1) Go over the syllabus. The syllabus reflects the organizational characteristics of the class. Unclear rules and requirements can come back to haunt you. Put in grade information (how many points for homework, exam, etc.) and tentative test dates. State your policy on late work and make-up exams. State your policy on office hours and provide contact information such as office number, phone number, and e-mail address. Provide information on

Page 5.555.1There is nothing magical about teamwork in engineering. For example, some types of teamsincrease the quality of life and facilitateaccomplishments. Other types of teamshinder productive work and createdisharmony and dissatisfaction. To useteamwork effectively, you must know whatis and what is not an effective group.There are many types of teams that can beused in engineering. Cooperative groupsare just one of them. When you choose touse (or are asked or required to use)groups, you must ask yourself “What typeof group am I involved in”? The followingchecklist may be helpful in answering thatquestion (See Figure 1).1. Pseudo Group: Members areassigned to work together but they have nointerest in doing so. They believe they
of an experience,Dewey refers to reflection on experience as a learning loop that runs back and forth between theexperience and the relationships being inferred5. The concept of the learning loop has gainedpopularity through the work of Kolb6 and his four stage experiential learning model: 1)experience; 2) reflection; 3) generalising or theorising; and 4) planning. Therefore, the idealexperiential learner will be able to 1) involve themselves in new experiences without bias; 2) reflect upon experiences from multiple perspectives; 3) integrate their observations into logically sound theories; and 4) use these theories in decision making and problem solving.This kind of practice is precisely what is being
