Graphics. During the five weeks where the laboratory consisted of the simulation experiments, the students were not required to attend the laboratory if they had completed the simulation at home prior to the lab time. If they chose not to attend lab, it was a requirement that they send me a copy of their completed simulation program. I could then verify that their solution met the design criteria. Several students were extremely pleased with this option because they lived 40 miles from campus and the lab was scheduled from 8:30 – 10:30 p.m. Some of the students worked on their design problems both at home and in the lab, some used only the scheduled lab period to

To circumventthis problem we have developed an experiment that usesvisible light, allowing students to directly observe theprocess and eliminating any hazards.

This includes understanding the purpose and objective of thelaboratory exercise, organizing and wiring the experimental set up, understanding whatmeasurements are required for the lab, and making a preliminary confirmation that theexperimental data taken, correctly agrees with the expected values.One week after the completion of the experiment, the Lead Engineer turns in a formal lab reportfor the laboratory exercise he or she supervises. If, over the course the laboratory term, theleadership rotates back to the original Lead Engineer, a second formal laboratory report
used for developing laboratory exercises is the wet/dry approach that combinessimulation (dry) of instrumentation circuits with a hands-on (wet) practical component. Thedepartment was already using the National Instruments LabVIEW simulation software forinstruction in its circuits, electronics, and test engineering laboratory course. It was thereforedetermined that this would be a good tool to use for developing the biomedical instrumentationlaboratory exercises. For the first set of laboratory exercises, a total of six experiments weredeveloped that led ultimately to the design and development of a crude ECG that could acquireECG signals that were then imported into LabVIEW and could be further analyzed using virtualinstruments (Vis) that are

In this simplified method, Excel worksheets are used to do the aforementionedmathematical procedure, and proved to be very effective and easy to use and understand byundergraduate students in OSU. The author used the same mathematical procedure in teachingthe advanced environmental control course in which the students showed real interest, improvedunderstanding of the subject, and appreciation of the results before hand. The use of a digitalcamera to document the model and the experiment is highly desired.3. ConclusionIn conclusion, this Daylighting Laboratory should be considered as a model to be adapted inother

The L-T-T concept has been implemented with success by educatorsfrom North Carolina A&T State University (Pai et. al. 1999). They designed a verticallyintegrated learning experience, where experienced (upper-level class) students can assist less-experienced (lower-level class) students how to use progressively more sophisticated softwarepackages throughout the curriculum. We would like to combine their experience to include thelearning through teaching component in our class and laboratory practice. Students will beasked to be involved in the laboratory preparation as well as participation in the actual teachingto

While emphasis is placedon the acquisition, analysis and reporting of data, the course relies heavily on experiments thatdemonstrate the interdisciplinary nature of instrumentation.The senior-level professors who teach the course have diverse backgrounds in electrical,computer, mechanical, and aeronautical engineering with significant instrumentation experiencein each
theoretical calculations for quality education, thevaluable role of simulation cannot be ignored [4]. First, the circuit simulation can provide astrong virtual laboratory environment for a practical experiment. Second, it is much faster tobuild or modify an electric circuit or system in simulation than in hardware. Third, with richcircuit analysis functionalities in most circuit simulation IT tools, analysis and design of anelectric/electronic circuit is very easy to perform in software simulation environment [5, 6]. However, it is critical to let students see the relation and comparison between hardwaremeasurement and software simulation in order for them to gain better understanding and strongerconfidence on using simulation IT tools for

Many programs have several four-credit engineering courses which include one labcredit hour, but the total lab time does not typically exceed four or five credit hours. This paperpresents integrated experiments as a way to make efficient use of scarce laboratory time.Integrated experiments are revisited in

In this presentation, we demonstrate our virtualexperiments and results of the assessment. We then recommend to what extent physicalexperiments can be replaced with virtual experiments without compromising student learning.IntroductionThe unit operations laboratory Texas Tech University is employed to reinforce to seniorchemical engineering students the basic chemical engineering principles associated with variouspieces of equipment. The unit operations laboratory is also used to familiarize the students withthe safety concerns regarding each piece of
LABORATORIES Modelling, simulation and visualization have been used by engineers to analyse physical phenomena and design complex engineering problems(1). The same methodology is now being extended as virtual laboratories to conduct laboratory experiments on computer screens with necessary hardware and software to link the computers to the physical experimental set up. Virtual laboratories can be classified as recreative or interactive or immersive or collaborative. The hierarchy of virtual laboratory development is shown in Fig. 1. Page 17.30.7 Immersive and

He joined the Department of Engineering Technology at Texas Southern University (TSU) as an Assistant Professor in the fall of 2006. He initiated the Virtual and Remote Laboratory (VR-Lab) at TSU in 2008. With the support of NSF HBCU-UP, CCLI and IEECI programs, a state of the art virtual and remote laboratory has been established. Now, the VR-Lab website is being served as portal for students to conduct various virtual and remote experiments. Page 22.1663.1

Constructivist learning theory asserts thatknowledge is not simply transmitted from teacher to student, but is actively constructed by themind of the learner through experiences. 3,4.Hands-on projects and problems with practical purpose tend to help students learn best 5.Laboratory based projects are the best vehicle for demonstrating many aspects of engineeringproblem solving situations. But in most cases, laboratory environments are set up as “exercises”which have very clear, predetermined outcomes. This is done to reinforce lecture material that ispresented in related courses 6.

State-of-the-art surface water purification includesseveral other techniques including reverse osmosis, membrane filtration, cartridge filtration, ionexchange, electrodialysis, aeration, and softening. On the other hands, students could attempt tobuild a solar powered treatment system. Such a project would certainly produce studententhusiasm. It should be noted that many universities incorporate newer surface water treatmenttechnologies into their laboratory experiments. This paper does not exclude these technologiesas an alternative to water treatment.Experimental SystemFigure 2 shows the system that was designed and built for this project.

But scholarsknow little about what actually happens during students’ research experiences that creates thesedesirable outcomes. We hypothesize that a crucial factor in students’ learning and developmentof engineering identity is how they are socialized into a research community. Our study draws ontheories from the fields of education and science and technology studies, such as expertise,identity formation, and situated learning in communities of practice. To investigate learning inlabs, we conducted participant observation in two engineering laboratories in a medium-sizedpublic research university for one academic year, which included attending meetings,interviewing lab

The primary elements of this laboratory are establishing acomprehensive facility in an interdisciplinary, team-oriented environment, and developing alaboratory curriculum based on hands-on experience. The key hardware element of suchcapability is an embeddable dSPACE digital signal processor (DSP) that can be connected tovarious sensors and actuators, depending upon the system objectives. The key software used inthe laboratory exercises is based on MATLAB/Simulink environment. The MATLAB/Simulinkenvironment is used to build the control algorithms, allowing the students to design, and testtheir controllers without being distracted by software implementation issues. The controllers arefirst designed in Simulink. Then, the Real-Time

An experimentaldesign is created with the intent of allowing undergraduate students to repeat a modified form ofthis experiment as an active-learning laboratory assignment for a Mechanics of Materials course,with copies of the test pieces with the most representative orientation changes being given tostudents for testing. An alternate version of the lab is presented which would allow students todevelop their own test pieces in a competition format.

It uses DOS laboratorywhich contains fourteen PC/ATs running under MINIX 1.5 (with networking kernel). This paperdescribes the course, the laboratory set-up, and the experiences in using the laboratory.Introduction Since the mid 1980s, two major advances in computer technology have been evident. First,powerful microprocessors (16, 32 and even 64 bit) with computing power of earlier mainframesare abundant. Secondly, a larger number of these can be connected together through high speednetworks which allow data transfer at 10 to 100 million bits per second. These have lead to increasing

These features provide a valuable toolfor a wide range of campus environments. The manual can be adapted by two- or four- yearprograms, and utilized with or without expensive laboratory equipment. The laboratorydescriptions include detailed photography of equipment, as well as quality video and sound clipsof the experiments and their application. In addition, multiple sets of data are included with eachexperiment. These data sets can be used in lieu of performing the

ConclusionsAn innovative first-year engineering laboratory in which students design and build simplephysical models of systems while emulating methods followed by practicing engineers has beendeveloped at the University of San Diego. This project helps students develop several keyengineering skills early in the curriculum and provides an entertaining yet challenging learningenvironment that also helps retain engineering students. Students were very enthusiastic aboutthe project. All of the students reported that the project improved their skills in open-endedproblem-solving and provided experience with engineering practice. Despite the amount ofwork required, students unanimously recommended that the project be continued. Since

Priorstudies have largely viewed the use of worked examples as an intervention to support learning,with the metrics of the study related to pre-/post- gains in understanding or ability. We areinterested in the details of how students use worked examples to solve problems, and there existsa gap in our current understanding of this facet of worked-example instruction. This gap in theliterature inspires the broader research we are conducting, as well as the specific researchquestions considered in this paper: • RQ1: what are the necessary components of a laboratory experiment designed to probe student usage of worked examples in support of problem solving?
