Finally, it will examine the role of the virtual classroom in today’sclassroom and its potential for future use. The final objective of this paper is to convey results ofan experiment to determine whether a virtual classroom environment will improve proficiency inthe economic principles of engineering design and its design process.II.

paradigm proposed here combines the advantages of laboratory teaching (e.g., hands-on experience) with an effective teaching of scientific methods and problem solving [1]. Ofcourse, a primary benefit of this method is that students play an active role in tackling ab-stract concepts, which have not been traditionally conducive to such participation. Further-more, these exercises result in an improved competency of the students in using spreadsheetsfor engineering purposes, thus preparing them better for their future professional endeav-ors. [1] The novelty of the proposed technique resides in its objective to illustrate abstractconcepts. This is a departure from prior efforts to use spreadsheets, CFD, or software toolssuch as Mathcad in the engineering

Since afew students gave more than five, and some students gave less than five suggestions, the totalnumber of usable responses was 352 (an average of 4.96 per student).

IntroductionA collaborative environment exists when a design team can create a product or system by fluidlyintegrating each team member’s knowledge and good ideas into the evolving design. That theseteams require excellent resources and training goes without saying. The pinnacle of acollaborative environment is a design team that simultaneously addresses design, manufacturing,environmental impact, marketing and economic issues, just to name a few.

EducationMost of the majors within a university curriculum are taught within a conscious, historicalframework. This is true across the spectrum from the liberal arts through the sciences. The majorhistorical figures within each field are identified and celebrated along with their works. Eachstudent readily identifies himself or herself as one of a long line of people learning and possiblycontributing later to their field. It humanizes their major and their activities within it.Engineering has not placed as much emphasis upon an historical context for its subjects and theengineers who have come before. Some educators such as Billington (1) and Petroski (2) havemade significant contributions to this area. But for the most part, the incorporation of

The faculty member serves as a consultant on technical mattersbut more importantly provides direction and assistance in matters of teamwork.The faculty member assigned to each team has the following responsibilities: 1. Provide assistance in getting the resources necessary to do the task assigned. Resources include such things as additional electronics for sensors, access to labs, instruments, and work space in off hours, and repair of broken parts. 2. Provide clarification and guidance as to team responsibilities. 3. Act as a fair arbiter in personality disputes

Teachers and assistants were asked to help the students make sure theyknew what questions were asking, without suggesting an answer.The first part of the survey consisted of four questions: 1. Is science fun? 2. Is science something you use all the time? 3. How often do you use science (every day, every month, every week, one or two times a year)? 4. Are you good at science?The second part consisted of ten pictures, of which the students were asked to mark the ones theythought were scientists (see Figure 1).

tenure-and-promotion process has resulted in a tenured position, hopefully at a higheracademic rank, there may be a tendency to think “I’ve made it, now I can take a break”. Well, inthis author’s opinion, in the classroom is the wrong place to take a “break”. That’s why you gotinto the world of academia, to work hard and do well by and for your students! But the need fora break is real, and that is the purpose of a sabbatical leave.The need for a sabbatical leave has been documented in the literature (1). University facultytypically work long hours during the academic year and in many cases during the breaks and thesummer term. In addition most university faculty recognize that their ability to teach and/or doresearch in their chosen field is

IntroductionThe principal factors for improvement in the performance and reliability of products are thedevelopment of new materials, novel use of existing materials, better understanding of thestructure-property relationships, and incorporation of both mechanics and materials science inthe design of structures. It is proposed to develop a new course, at the junior level in mechanicalengineering, linking materials science, mechanics of materials, and design, based on the above-mentioned factors.In present engineering practice, structural components are designed by using the mechanicalbehavior of real

Currently Linux can be found in devices as small as a wristwatch [1] and as large asa Beowulf class supercomputer [2]. The popularity of Linux is based on three factors: - costs are lower because the software is free and it runs well on less expensive hardware. - it has more software, capabilities, and features than other operating systems. - the source code is open, so users can customize the operating system to meet their needs.This workshop will present the Linux operating system in general, and its current status in com-puting.

Theunderstanding is achieved through knowledge in three areas, (1) the behavior of the abioticcomponents, (2) the behavior of the biotic components, and (3) the relationships between thebiotic and abiotic components, and the resulting dynamic responses of the system. In ourprogram this is achieved through a combination of laboratory experiences and classroominstruction. In one of these laboratories, the emphasis is on the experimental design and practicalimplementation of systems with living components. The premise of the exercise is that, ifstudents truly understand the requirements of living creatures, they can keep those animals aliveand healthy.
