theperformance.Figure 6 shows a similar comparison study of the same samples in the small tube. For the low-cost tube, the absorption measured is significantly higher than empty reference tube. This isattributed to the rougher surface finish the schedule 40 PVC pipes use that causes disturbance inplaner wave. For higher performing samples i.e. fiberglass and cotton shoddy, the agreement inperformance is acceptable.We believe the tube is very useful for instructional purpose as well as conducting relativecomparisons among various acoustic materials in order to rank order the test materials withoutrequirement of expensive laboratory testing or similar test practices. It appears that the relativerank ordering is the same for results from the reference tube as

These learning objectives are: calculate fluid thrust forces, calculateaerodynamic forces, solve pipe flow problems, select a pump for a system, select a flowmeter fora system, write a computer program to solve transient fluids problems, write a professionalquality lab report, acquire and analyze laboratory data, and be a valuable member of team thatsuccessfully completes a project. The learning objectives can be mapped to ABET studentoutcomes. In this implementation of Standards-Based Grading, all assessments are done on apass-fail basis.

PIV Background PIV is a proven [11], minimally intrusive, flow visualization and measurement techniquewhich employs a digital imager, a high power laser, laser sheet optics, and a fluid of interestseeded using neutrally buoyant “seeding” particles (Figure 1). In many ways, PIV is uniquelysuited for education in that it allows qualitative and quantitative observation of actual flows inreal time. However, laboratory grade PIV systems are traditionally expensive and requireexperienced users for safe and accurate measurement of flow fields. The high cost of these PIVsystems stems from the individual costs of high

Byconducting the project in phases throughout the semester, it applies the “guidance, practice, andfeedback” [4] requirement for effective learning experiences.While searching the literature, the author could not find a similar scheme that focused itsapproach on achieving sizing expertise by “conditionalizing” the learning experience with anexisting machine. However, there were other noteworthy approaches which are summarizedbelow.Pierce, et al. [9] presented a comprehensive design experience that consisted of designing severalcomponents of a ski lift system. The machine design course included a laboratory, which is nottypical in mechanical engineering curricula

[5] described progress on development ofConcept Inventory assessment instruments, which could be used by instructors to judge theadequacy of their instruction, and upon inclusion of data segregated by how content wasmanaged and delivered, to identify effective practices, and relate specific teaching techniques tostudent learning across multiple subjects. These subjects included thermodynamics; solidmechanics; signals and processing; electromagnetics; fluid mechanics; heat transfer, and more[5]. In discussing development of Concept Inventory assessment instruments related to thesubject thermal and transport phenomena (e.g. thermodynamics

Accelerometers that are embedded in the sensorswere used to identify any additional movements by the participants and were used as criteria todetermine potential outliers in the data as described by others [28].Each electrodermal sensor recorded the electrical conductivity of the skin (in microSiemens, µS)at a frequency of 4Hz (period is 1/4 of a second) at a low electrical current of 1100mAh(Empatica, Boston, MA) during the laboratory session. Each participant was in the session for anaverage span of two hours, which yielded approximately 28,800 data points per participant.

The strain signals pass through the Wheatstonebridges and amplifiers shown in Figure 12. The signals output from CH0 and CH1ports as shownin Figure 11. As shown in Figure 12, the data acquisition module contains a screw terminalinput, Wheatstone bridge, amplifier, and BNC output for each channel. The module is poweredby a laboratory DC supply or four internal AA batteries. All the components are mounted on apanel of perfboard and placed in a recycled computer power supply case. Integrating theelectrical components into such module minimizes electromagnetic interference and short circuitoccurrence. The analog signals

According to Hurtado et al.[1], these undergraduate research opportunities have further facilitated the decision of pursuingSTEM careers and Ph.D. studies post-graduation [5].However, experiencing success, such as procuring an internship position, joining an undergraduateresearch laboratory, or being able to attend graduate school, highly depends on maintaining acompetitive grade-point average (GPA).

0.002% uncertainty. To somestudents, this appears to be a reasonable if not a preferred representation of the final answer. Inan engineering thermodynamics course, this concept is more difficult for students since propertyvalues reported in tables often are specified at 6 significant digits, which can be interpreted as1/500000 or 0.0002% uncertainty. Having property values in thermodynamic tables expressed to6 significant digits, contributes to the students’ perception that more digits are better.Students are expected to learn to estimate uncertainties in laboratory measurements and be ableto propagate these to final reported measurement values. This is expected in ABET1 outcome (b)describing the “ability to design and conduct experiments

This approach aligns with many of the personal effectiveness techniques.While there are multiple uses of the Four Pillars of Manufacturing Knowledge, for the purposesof this paper, the focus is on fostering ongoing dialog among faculty in mechanical engineeringand mechanical engineering technology programs whose graduates often work in manufacturingengineering functions of product-producing industries. Such dialog will help to
deal of debugging. Gragson tells arepresentative story of a chemistry laboratory class that was modified in an effort to promotegeneral improvement in student writing skills by offering extended instruction on report writingand better writing feedback on graded reports.9 To meet these goals, the number of projectreports was reduced from 10 to 4, and the instructors created from scratch a writing manual foruse in the course. An elaborate peer-review process was also implemented, along with a systemfor assuring that students actually performed their peer-reviewing tasks. This paper judgesstudent performance to be satisfactory, but large questions remain open; student retention of thewriting lessons was not assessed in subsequent classes or in
larger range of materials than traditional mechanics of materials courses.Evaluation of the redesign is preliminary at this stage.

The students were also asked to verify and report their obtained values against thosereported in the literature as much as possible. Additionally, the students were also asked toidentify the sources of error in their experimental model that would have resulted in deviations(if any) of their calculated friction coefficient values. Majority of the students (greater than 90%)were able to report values and reflect upon their results and the deviations they observed.Considering that this is not a controlled laboratory experiment where all the equipment andparameters are strictly controlled, the simple experimental models built by the students workedquite well to
