Pedagogical Best PracticesAbstractThe pedagogy of laboratory courses has been well discussed in the literature, but the extent towhich these best practices are incorporated into laboratory experiment design varies wildly. AtNortheastern University, various capstone design teams over the years have been tasked withdesigning new experimental apparatus for the undergraduate teaching laboratories along withappropriate lab handouts and other instructional material. In many cases, the students involved inthese projects have taken the lab class for which they are designing the experiment and havereported negative experiences, and therefore are motivated to try to improve the class for futurestudents. Student designed labs have the potential to reduce burden

Born from the predictions anddiscoveries of many scientists like Feynman, Eigler and Zsigmondy, nanotechnology deals indimensions from 1 to 100 nanometers [5]. A size that can be difficult to conceptualize. Tohelp students with this task a laboratory experiment was designed as of an associate levelcourse in nanotechnology. This experiment merges three common experiments into a singleexercise to help students comprehend the physical size of nanoparticles, and introduce tothem a few unique properties these particles may possess.3

Following thevision, we have designed a virtual venturimeter experiment module as part of the proposedthermo-fluids virtual lab which permits students to perform the experiments interactively bymanipulating an e-valve on the computer screen. A special feature of the module is the hands-onexperience which is often missing for distance learning students who passively view video or CD-ROM of previously recorded physical experiments. The collaborative work environment,generally encountered in laboratories is not included in the present study but will be reported in afuture publication.Methodology Page 8.925.3

Session 2653 An Engineering Laboratory Experience for a Freshman Engineering Class Craig W. Somerton, Craig J. Gunn Michigan State UniversityIntroductionEngineering laboratory experiences are different from science laboratory experiences in that theyare more focused on problem solving rather than discovery. Hence, it would seem important tointroduce freshmen engineering majors to this difference by giving them an exposure to anengineering laboratory.

. For example according to the Power Supply Design guideissued by Server System Infrastructure forum, the active PFC is a requirement for Server SystemInfrastructure (SSI) compliance: “The power supply modules shall incorporate universal powerinput with active power factor correction, which shall reduce line harmonics in accordancewith … standards.”11 Due to the increasing importance of active PFC, there is then the need toeducate future electrical engineers to understand the operation and benefits of active PFC. At CalPoly, we have addressed this issue by having one laboratory experiment on boost-converteractive PFC in the second course of our power electronics series. This paper illustrates the contentof the lab experiment as well as the
compressive strength reinforce topics discussed inclass lectures. Teaching aids and laboratory experiments are an effective method ofdemonstrating important concepts and can be used to enhance the learning of structuralmaterials.IntroductionMany civil engineering curriculums require at least one course in materials and materials testing.These classes provide students the basic knowledge and understanding of the production,properties, testing, and behavior of common structural materials. A large emphasis is placed onconcrete, steel, and wood due to their wide use and availability in the design and construction ofstructures. This paper presents teaching aids and laboratory experiments that have been used bythe authors in their respective classes. These
accommodate for students that are visual learners,auditory learners, and kinesthetic learners. It is a fact that the students learn better whenthey participate in the learning process, instead of just playing a passive roll. Usingpresent technology, there is the possibility to visualize the abstract calculus concepts byperforming virtual experiments that will permit the active participation of the student inthe learning process. This paper presents two virtual electronic laboratory experiments tobe used as an aid in the visualization of two of the main calculus concepts: Integrationand Differentiation. These experiments were designed using electronic simulationsoftware and contain, as main elements: operational amplifiers, resistances, andcapacitors
applications.Preparations were made for the new nanotechnology laboratory course including procuringlaboratory space, ordering some of the equipment and supplies, and performing preliminarytesting of some of the experiments. Two undergraduate students performed preliminary testingof the silver nanoparticle synthesis experiments during 2014. The preliminary experiments werebased on an existing technique for creating silver nanoprisms5, and were designed to use one labperiod to synthesize the silver nanoprisms and characterize them using spectrophotometry and asecond lab period to characterize the particles using a transmission electron microscope (TEM).Nanotechnology ModulesA nanotechnology module was developed for the split level technical elective ECE 4283-01

laboratory exercises in education leads tothe supposition that the combination of the two can be a highly effective teaching method.However, this combination is not widely reported. Indeed, only one reference was found thatspecifically dealt with using a computer application to both conduct a laboratory experiment andinteract with the laboratory hardware. D’Souza, Scott, and Stone11 describe “. . a computercontrolled vibration laboratory that is inherently safe and does not need an instructor. Thelaboratory is controlled through the computer which protects both it and the student. Results arecollected and analysed by the computer. Most importantly the laboratory has been designed tobehave in a different manner from the theoretical models developed
understanding and learning outcomes.In conclusion, following the development and implementation of the interaction in the laboratoryclassroom, valuable insights have emerged. These insights highlight the effectiveness of VRinteraction in actively engaging students in the exploration of complex concepts within agamified-like environment. Both Instructional Designers and Programmers acknowledged thecapability of Unreal Engine to enhance and complement the laboratory learning experience. Theintroduction of the VR application as a supplementary resource significantly increased studentengagement. Students were not only prompted to critically assess the interaction's alignment withexperimental insights but also encouraged to express their opinions on the
accomplished in a “web-ring”. Each institution provides specificexperiment(s), for which laboratory equipment is shared together with experimental data andprotocols. The bandwidth and number of users from each institution is “paid” in proportion totheir contribution in terms of equipment and accessibility time. This is very good for overseascooperation since the time differential favors extended use during periods when the homeinstitution students are otherwise asleep. The diversity of electrical engineering topics taughtand practically performed can be extended in this way.4.

To address these issues, there are a number of initiatives that have been made to provideexperimentation facilities over the Internet 3, 4, 5, 6, 7, 8, 9. None of these facilities are designed todeliver a laboratory course that is a part of a regular educational program. In addition to these,all these suffer from one or more of the three main drawbacks. These are: a) complexity indevelopment; b) higher cost; and c) single server can provide access to only one experiment at apoint in time. Although the Internet-based laboratory facilities have a number of potentialbenefits, these drawbacks hinder the process of gaining their popularity. The paper will describe the
