the course was upgraded. The resultsof students’ survey on laboratory experience showed positive feedbacks in working with theVEX robotic kits and the MPLAB programming environment. However, students raisedconcerns that the VEX robotic kits did not offer enough sufficiency to build their designedsystem (Question 1 in Table 3). The author is constantly improving the course content and thelaboratory using students’ feedback. More VEX parts were added to the kits during the summerof 2008 based on students’ feedback. The score for Question 1 in the survey in the fall of 2008shows a small improvement. More parts are planned to be added during the summer of 2009.AcknowledgementThis work was supported by 2007 Summer Instructional Development Grant
figure1 as their set of outcomes to be assessed, conclude that there is a strong tendencyfor the simulation labs to emphasize conceptual understanding. Here we plan to limit the scopeof our investigation to formative assessment of conceptual understanding while further limitingdiscussion to online electrical engineering/technology laboratories which we take to include electrooptical laboratories. Various researchers have discussed implementation of online electrical engineering and network-ing laboratories [3, 8, 13, 29, 31, 26, 45, 40] without detailing their assessment approaches. Mostresearchers who have reported the results of their assessments of such online labs have concludedthat the laboratories were most effective according to the
communication skillsthrough written reports, experimental data analyses and presentation of the results. It is expectedthat this equipment will allow us to enrich our curriculum with many research-quality tests,which will in turn enrich the potential scope of senior projects for our students.Providing Undergraduates Opportunities to Work in a Research EnvironmentAll experiments are planned to include the participation of undergraduate students in thedevelopment of laboratory content. Students are an important part of the curriculum revisionprocess at SFSU. This is especially true for development of the laboratory, which will be set upbased on educational objectives to maximum learning, promote student participation and helpmentor student development
. Thelaboratory course brings together undergraduates from two engineering departments (electricaland mechanical) with plans to include systems and computer science students in the near future.Laboratory Hardware/Software InterfaceTo concentrate fully on the actual control design task and allow students to gain experience withindustrial control development tools, a dSPACE DS1104 DSP board6 is chosen as the maininterface between the controlled system (process) and the host computer. One of the salientfeatures of the dSPACE DS 1104 DSP-board is the ease of building real-time applications. Inorder for students to access the I/O dSPACE DS 1104 DSP-board, a software interface to theboard is required. Here, the student has two options: 1) the student can

learning thematerial themselves, regular class periods and the weekly lab session that were devoted to thetopic of Nonlinear Equations as in Summer 2003 were cancelled. At the end of the week, as partof their graded homework assignment, students were asked to submit answers to 18 shortquestions (6 on each of the 3 subtopics of Background, Bisection Method, and Newton-RaphsonMethod) that were based on six levels of Bloom’s taxonomy. The reading assignments andproblem sets were the same as in Summer 2003.1 We were planning to implement the fourth modality in Summer 2005.

lecture.Not all technical courses in the discipline have a laboratory component, nor does TAC-ABET accreditation require it. Moreover, there is no fixed percentage that governs this.However, in keeping with the educational objectives and learning outcomes fortechnology programs, most institutions, accredited or not, deliver 40% of their courseswith a laboratory as part of it. It is this heavy “hands-on” experiential laboratorycomponent, that we believe is the primary barrier to a purely distance program in mosttechnology programs and EET/CET in particular.Scope of the ProblemTo quantify the size of the problem, we focused on the EET and CET programs at ourinstitution. Both are structured with 4-year course plans requiring 130 credits (39courses) to
difficultto creatively apply to practical engineering problems. Felder and Brent confirm this intuitionwith several studies that show students need repetitive practice with consistent feedback todevelop new skills (1). Simply showing students how to solve a particular problem doesn’tguarantee they can apply these concepts on their own. With these ideas in mind, the lab morphedfrom a traditional recitation to weekly programming challenges solved in a group setting. Thelaboratory and lecture now focus on the C++ and MATLAB languages with plans to alsoincorporate Python in future semesters. This paper details the changes to the laboratory portion of the course to use problem-based learning (PBL) and just-in-time teaching (JiTT) in a collaborative
meaningful as possible.The initial plan was to have one 3D printed jet engine, and have the students install their sensorsand actuators on to the same system. However, this proved challenging since both the teamswanted to choose a different method of actuation, and different configurations. Since the CADdesigns were ready, it was decided to 3D print another setup so that the groups could workindependently.The other challenge students faced was the time required to get the finished 3D printed parts. The3D prints usually have support material. The support material is removed by dissolving it in a hotchemical bath which took some considerable amount of time. Therefore, in order to reduce timeneeded to print all the parts, the students decided to

activities related to3D printing as common elements of the engineering design process in general, and rapidprototyping in particular. ABS and PLA 3D-printing materials were regarded as environmentallyresponsible products. Community involvement and appreciation of the sustainability efforts inthe department’s 3D-printing lab were unintended positive results.With further improvements of the desktop recycling system, new opportunities may arise. Forexample, the sustainable 3D-printing lab may accept 3D-printed recyclable materials from othereducational institutions in the area. Also, commercial applications could be developed to helprecycling efforts in 3D-printing shops and makerspaces. Further research is planned to includerecyclability

Students from electricalbackgrounds have gained CAD and fabrication skills, while students from mechanicalbackgrounds have gained experience in wiring and sensors.

dynamics, a major part of ME240. The DCI comprises29 multiple-choice questions that map onto 14 of the most misunderstood concepts. The four i-Newton demonstrations included in this study were designed to reveal multiple DCI concepts.We also hypothesized that the i-Newton demonstrations would increase students’ self efficacy,defined as a person’s beliefs of how well they can complete and execute a plan or goal11, 12.Instilling a strong self-efficacy comes from increasing one’s knowledge and positive experiencesassociated with the outcome11, so it is logical to expect that having a stronger understanding ofthe fundamental concepts may improve self efficacy Previous studies have examined self-efficacy in undergraduate students in regards to
materials engineering classes with therefinements discussed above.Finally, the research group has begun evaluating long term retention. A small group of upperyear students volunteered to complete the Concept Inventory. Students currently in their fourthyear of engineering would not have completed this particular laboratory experiment; rather theywould have learned the concept of crystal structures with 2D materials from lecture slides andtextbooks, etc. Those in third and second year engineering would have completed thisexperiment. The research group plans to continue delivering the MCI to these students annuallyto gather whether completing this lab in first year engineering leads to increased conceptretention. As of now, the sample size is too
to build the circuits with thecomplete schematics provided. More design components are planned in the future in order tochallenge the students and provide more active learning experience. In the second project, theblock diagram of the triangle waveform generator will be provided, but the detailed circuitdesign and part value need to be figured out by the students.ConclusionsThis paper presents the implementation of two hands-on circuit building projects in anElectronics course in a crowded general engineering curriculum. The students independentlycompleted the two sequential projects outside of class time. While it was observed to bechallenging for the students and the learning experience can be further improved, the assessmentresults show
limitation is due tothe small packet size used to transmit data. This was an acceptable level of performance for thetensile test experiments, but the software will need to be modified if higher sampling rates arerequired. Finally, the novelty of the TabletPCs initially distracted some students from the actualtest. Fortunately this was only a temporary problem.In the future we plan to modify the TabletPC software to make it easier to use with otherexperiments in other university departments. The mechanical engineering department iscurrently in the process of instrumenting a four cycle engine. We will be using the wireless dataacquisition system on this lab to allow student to monitor various parameters such as engine

From the sixth to the tenth week, students had time to work on the implementation of their projects. 5. During the eighth week, one group gave a public presentation of its project to a group of visiting students and their families during one of the school’s scheduled events for new prospective students, the “school’s recruiting, preview weekends”. From the
engineeringcurricula, concerns over the low resource efficiency often dominate such that some laboratorystudies are withdrawn from the teaching plan. Such decisions, it is argued, will be detrimentalto the undergraduates learning experience. Page 12.1568.2This paper demonstrates two approaches to redress the issue. In the first example technologyis developed to better support the resource efficiency whereas in the second exampletechnology and students are used to better support the development of the educationaleffectiveness of the laboratory experience.Example 1.

through independent discovery. This is an innovative approach tointegrating technology into the teaching/learning process for laboratory oriented courses and canchange our fundamental approach to laboratory environments.Redesigning the Laboratory CoursesThis was an introduction for both the students and the faculty to this method. But this methodhas the potential to completely revolutionize the laboratory courses. We are redesigning andrewriting the experiments such that each group of students can perform a separate module of theexperiment independently. For example, we are planning to include an experiment that aims todesign the load for a motor. This is possible because the physical machine hardware in thislaboratory uses an active load which

experiments on various systems level concepts such as amplification,analog filtering and modulation. Detailed information about the course and the hardwarelaboratory can be found in the proceedings of this conference in another paper by the first authorof this paper.To assess our success in several key areas, carefully planned student surveys were conducted andspecific assessment questions were included in the exams. First and foremost, these studiesindicated that spending three hours in the laboratory every week is not sufficient for thebeginning students to master the modern bench-top measurement instruments. We saw thatstudents' struggles with the instruments (especially during the first half of the semester) couldresult in frustration in the
adjacent space (open plan design), the model becomes bigger (or much bigger) in size and harder to build and to handle. 4. When students use a glass type that may modify the light distribution inside the space modeled, a sample of that glass type should be used. This is especially important with the use of Plexigls, or any other diffusing glass type.6. ConclusionImplementation of the laboratory-oriented testing as a design-assisting tool for daylightingsystems (in buildings) is a successful example of evidence-based design. Testing physicalmodels under the appropriate design sky condition in a fully-controlled laboratory setting assuresthe accuracy of the results; since this method takes into account all of the design

Based on the students’ feedback received in fall 2012, theinvestigators improved the Power Point presentations and standard operating procedures (SOPs),and further made some adjustments on laboratory planning and scheduling. As a result, theratings were improved in fall 2013.Figure 5 displays the histogram showing the class ratings of each laboratory module obtained infall 2013. Eight out of the twelve labs for Q2-Q4 were rated around 9.5 out of 10 manifesting thestudents’ true interest and good experiences with the novel, high-quality nanolab course.

The instructorfeedback is carefully calibrated to engage the students in identifying the gaps in their currentdesign and to direct their thinking on how they can address those gaps rather than simplycorrecting errors in the students’ approach. The team must have its design approved (typicallyafter a revision) before they are allowed to run experiments in the virtual laboratory.

This process is punctuated by aTeam Update Meeting (TUM
taxonomy firm, we drafted multiple versions of the taxonomy. The sixth/currentversion of the taxonomy includes 14 categories and five levels of organization for the 452 terms. Nextsteps involve validating and finalizing the taxonomy and disseminating it.We are hopeful that the taxonomy will be used broadly. Researchers and community members will beable to use the taxonomy to situate individual research initiatives in the broader field, see connectionswith others, and plan future work. Journal editors will be able to use the taxonomy to organize relatedresearch areas and to create a reviewer database. Funding agencies will be able to use the taxonomy toclassify research portfolios, identify areas for capacity building, frame solicitations, and
the traits they claim to be seeking. Overall, theseresults may assist the engineering profession in its transition into the future by highlighting waysin which universities and companies, classrooms and office spaces, and students andprofessionals can adjust to meet the growing global challenges and create more preparedengineers of the future. Our poster presentation will summarize the project objectives, methods,and findings to date, including the pilot survey data, and it will share our plans for disseminationof the findings and future research.AcknowledgementsThis material is based in part upon work supported by the National Science Foundation Researchin Engineering Education program under Grant No. 1129178.
