Hands-on ability is considered an important characteristic of practicalingenuity2. Two of the ABET criteria address hands-on skills: ability to design and conductexperiments and interpret data (criteria b); and ability to use the techniques, skills, and modernengineering tools necessary for engineering practice (criteria k)3. Employers value hands-onability and routinely ask recruits about hands-on experiences outside of classes4. A “tinkeringdeficit” has also been identified that puts females
Industry–Student Partnerships in Development and Sharing of Educational Content Involving LabVIEWAbstractThe biomedical engineering (BME) students at our university often need hardware and softwarefor data acquisition, automation and data analysis for their instrumentation laboratory classes andopen-ended design projects every semester. We have teamed with the Education Division atNational Instruments to form a collaborative partnership for the necessary resources and to createteaching material to facilitate students with their design projects. National Instruments havedonated NI ELVIS system instrumentation equipment during the 2007–2008 academic year aswell as continuous support to help students with their learning objectives

Students use MATLAB and Simulinksoftware tools together with personal low-cost SDR hardware, allowing them to conductexperiments and investigations outside the traditional undergraduate laboratory setting. Througha balanced pedagogical approach involving in class experimentation and outside of classprojects, the laboratory modules are designed to ensure strong understanding of foundationaltopics while simultaneously engaging and motivating students through investigation of real-world wireless communication signals and systems.Details of the course approach, structure, and

These activities were utilized and all studentscompleted all of the
students experience in bioreactor design and characterization. The goal of the projectis to design and characterize a batch enzyme reactor to convert cellobiose to glucose. The classproject is divided into two parts: experimental and modeling. For the experimental part, studentsutilize a temperature-controlled bioreactor to measure the product formation from the enzymaticbreakdown of cellobiose to glucose. For the modeling part, the students develop a mathematicalmodel to predict the conversion of cellobiose to glucose in the bioreactor. They have one, three-hour laboratory period to collect data from the reactor. The students then compare theirmathematical models to experimental data from the bioreactor and determine if the model isacceptable or
. It is also an important ABET Learning Outcome. Student technical writtenand oral communication are embedded in courses spanning the undergraduate experience,traditionally leaving the basic writing skills to be addressed in composition or English courses. Arecent restructuring of the University’s core curriculum heightened not only the practice ofwriting across the curriculum but emphasized the practice of writing in the discipline. Toaccommodate the new core curriculum, it was necessary for each engineering program at theUniversity to redesign one of its courses to be designated writing intensive.The Mechanical Engineering curriculum at the University of New Haven, even prior to the newcore, included a sequence of 3 laboratory courses, each
Switching Regulator OperationIntroductionAt the University of Virginia, we have experienced increased student interest in alternate andrenewable energy topics in Electrical and Computer Engineering over the past five years. Thishas presented a challenge, as we currently only offer a single "Electromagnetic EnergyConversion" course, which is in a lecture format with a required associated laboratory section.To address this challenge, we have been systematically phasing out older topics, i.e., D.C.motors, and adding course content relevant to photovoltaics and wind energy production, i.e.,microgrids [1]. This has necessitated a redesign of some of our laboratory experiences andrequired us to reconsider the most efficient way to transmit a breadth of
and analysis of filter circuits. A missing element is the laboratory experience of thevoltage addition of phasors. Before introducing this experiment to our Fundamentalscoursework, students at the University of Virginia would never see this concept without takingour course in Electromagnetic Energy Conversion in which they would deal with polyphasesystems. We also realized that having a lab bench accessory that would produce phase-shiftedsinusoids could be employed as a teaching tool for reinforcing concepts in superposition andoperational amplifier circuits, as well as phasor analysis.Our design is shown in Figure 7. Note that it is also a very compact design and that the pins matewith the solderless breadboard such that power and ground are

Implicit in a teacher’s performance in the classroom are mental models of the contentknowledge being taught, its enactment in the real world, and how that enactment might beframed for teaching21 (pedagogical content knowledge22, metastrategic knowledge23, andpedagogical design capacity24). While a teacher is obligated to provide a set of experiences thatlead students to key understandings and skills associated with a given curriculum, the teacher isnot obligated to articulate for herself or disclose to others the mental model(s) that led to herparticular enactment of curriculum in the classroom. Indeed, the teacher might not be aware ofthe mental model(s) that underpin her assumptions about content and procedural choices made inlearning and

This is particularly true for engineering technologystudents, since hands-on experience is a critical component of their education.Seamless integration of classroom and laboratory experiences through modeling, simulation andvirtual laboratories will improve students’ analysis, design, and troubleshooting capabilities.Their overall learning will be significantly improved and laboratory time spent will be drasticallyreduced.1.2.

Students prescribed a “challenge” water based upon the potentialuse of the devices for Army soldiers under austere conditions and they designed an initiallaboratory evaluation of the devices. Their constraints as they designed the laboratory evaluationincluded their resources (i.e., time, people available, instrumentation and equipment availability)and safety as they considered the evaluation of multiple contaminants across the physical,chemical (organic and inorganic), and microbiological realms. The student teams prepared alaboratory evaluation report of their findings.From this experience, the students gained an appreciation for the capabilities of the

InstructionMotivationUndergraduate engineering programs seek to train students in the process skills of engineering,which include designing hypotheses, identifying and synthesizing relevant literature, interpretingand analyzing data, and presenting findings [1]. While engineering educators routinely reportthat engineering process skills are critical, many report difficulty teaching students these skillsdue to time constraints [2]. Librarians, who specialize in the organization of information anddata, are well-equipped to help biomedical engineering (BME) educators address some of thesegaps in their students’ learning [3]. This project sought to determine whether integrating aspecialized information literacy curriculum into a BME laboratory course sequence couldimprove
