Education in IndiaIntroductionQuality of engineering education, which is essential for the economic growth of the nation, hasemerged as a factor of paramount importance in India, today. This has led to several discussionson reforms in teaching-learning processes in engineering classrooms 1, 2.In particular, laboratory courses form an integral part of the degree programs in engineering.Concepts taught through lectures are often complemented by laboratory experiments which arecritical to enable learners to further develop their knowledge and skills. Student participation,however, in these laboratory based courses has been largely disappointing. It is often times ateacher’s experience that students are either not very interested in their laboratory
of devices, including high-aspect-ratioand high-density laminated magnetic cores and multi-layered windings for advanced micro-magnetic generators, as developed by Arnold, et al.1 For these types of devices, the magneticand electrical properties of the materials are most critical for performance, however, since thesedevices involve micro-rotating machinery, the mechanical properties of the materials are alsocritical for operation and durability. For these reasons, Neodymium Iron Boron (NdFeB) is usedas the permanent magnet material of choice, whereas electrodeposited nickel-iron (Ni80Fe20) isused as the back iron material as well as to fill the cavities between the silicon and the permanentmagnet, and to laminate the permanent magnet inside
level during the experiment. For each of the courses, laboratory sessions were heldonce a week, and each session was 1 hour and 50 minutes long. The survey included questionsabout the following topics: • the student’s frustration level during the experiment • perception of the duration of the laboratory session • primary causes of their frustration (equipment or troubleshooting issues, difficulty with theoretical concepts, lack of support from the instructor, confusing lab document, difficulty working with partner, or outside distractions) • whether there were any pre-lab exercises, and whether these were helpful • whether the instructor’s introduction was too brief or too prolonged • confidence level
, as shown in Table 1, to measure students’ performance.The rubric identifies six pertinent abilities that students must develop during their studies in themechanical engineering program. They are the abilities to identify objectives, to use appropriatetools and methods, to conduct experiments safely, to collect sufficient data and apply statisticalanalysis, to evaluate results for validation of objectives, and to formulate an experiment toevaluate an engineering problem. There are four levels of achievement criteria that each studentmust display. The program aims that every senior in the program meets or exceeds criteria 3. Inorder to attain the goal, the program has been requiring that each mechanical engineeringlaboratory course contains an
in laboratory courses come to physical lab sessions withoutadequate preparation, often not knowing even the main objective of the experiment. This isdespite instructions to students to review the details of experiments from the lab book providedto all students in the course. Due to their highly visual and immersive nature VR labs areexpected to remedy this situation and improve students’ preparedness for the physical labsessions. Students’ exposure to an experiment in both physical and virtual domains is expected toreinforce students’ learning. Since majority of current engineering students are technology savvyvisual learners [1], the highly visual nature of the VR labs is also expected to make students’ labexperience engaging and exciting
(without doing the calculations) and keep itinteresting?” The solution presented here is, “The addition of hands-on experiments thatreinforce the concepts and examples presented in class.” It is the goal of many teachers to weave hands-on experiences into the traditional lectureformat. It has been shown, that among other benefits, hands-on learning helps studentsremember what they are being taught [2-5]. It was clear (at least to me) that what the “Design ofExperiments” class needed was “EXPERIMENTS!” This sentiment is echoed in a paper byWilliam G. Hunter [1] , a noted statistical text book author. Hunter stated that students get plentyof practice analyzing data through homework, but little or no practice designing a realisticexperiment

Metrology is an extremely broad field, but may be generally divided into threemain subfields: (1) Scientific or fundamental metrology, (2) Applied or industrial metrology,and (3) Legal metrology. Scientific or fundamental metrology concerns the establishment ofquantity systems, unit systems, units of measurement; the development of new measurementmethods and techniques; realization of measurement standards; and the transfer of traceabilityfrom these standards to users in society. Applied or industrial metrology concerns theapplication of measurement science to manufacturing, construction

This program takes the accelerometer values from the phone and basedon the amount of axial tilt sends the corresponding 7 bit command to the Bluetoothmodule on the robot. Simple commands are then issued to the servo microcontroller fromthe Bluetooth module. This hierarchy allows easy and efficient changes in theimplementation of the command scheme without requiring a redesign of the entire servofirmware package.

illustrative applications, finally giving students practice insolving problems along similar lines. The aspect of ‘how’ is given importance while the questionof ‘why’ is undermined or neglected. What practical problems can they be used to solve, andwhy should the students care about any of it? Leading educational theorists agree that thisapproach is not always successful in fostering understanding, synthesis, eventual application ofknowledge, and the ability to use information. A well-established precept of educationalpsychology is that people are most strongly motivated to learn things they clearly perceive aneed to know.1, 2 A preferable alternative is inductive teaching and learning.

Four prerequisite courses are brieflydescribed before focusing on the project based capstone course. These four coursesprovide the students with the technical skill sets needed to succeed in the senior levelcapstone course. Accomplishments and outcomes from the student perspective, theUniversity perspective, and the industry perspective will also be shared.Our advancing world of computer integration, process control, industrial automation, andtelecommunications requires technical problem solvers and knowledgeable decisionmakers. “The activities of problem solving and decision making are closelyintertwined”,1 and both skills can

In his paper, entitled “Tell me, I’ll forget; showme, I’ll remember, involve me, I’ll understand;” Eastlake states, “Engineering without labs is adifferent discipline. If we cut out labs we might as well rename our degrees AppliedMathematics.”1 Although there isn’t much discussion about removing labs from engineeringeducation, this statement does help emphasize the importance of laboratory experiences inengineering curricula as a key method for promoting student learning. Also, many students

In addition to assigning numerical values (on a scale from 1 to 6) for theirresponses to the survey statements, students were asked to respond with short, writtenstatements.A similar rating of survey statements such as: “I am familiar with the engineering designprocess” (average values of 3.67 and 3.89) and “My partner came up with many ideas on how tobuild the racer” (average values of 4.78 and 4.60) suggests that the two groups had similarbackgrounds about the engineering design process and that internal group interaction weresimilar, respectively.Stronger agreement was found in the control group for the statements

With this development, our experimental packagedelivered to off-campus students was expanded to include the original components pack plus anadditional “HELP” kit.26 The HELP kit (figure 1) contained essential, but low-cost testequipment required in any electronics workshop: Page 25.1386.3 A battery-powered audio signal generator (Digitech QT-2302).27 A two-channel PC-USB oscilloscope and accessories (PoScope).28 A
, so that the pendulum can swing freely (see Fig. 1). A 2-inpropeller (model U-80) is attached to the motor shaft to produce a thrust force in order to controlthe angular position of the pendulum. The portability of the kit is enhanced by an innovativedesign allowing the kit to be shipped in a flat 2-in-thick box as shown in Fig. 1(left). A fastener-free design allows the kit to be assembled into its operating condition by interlocking threeacrylic plates which interlock when rotated by 45 degrees with respect to the base plate as shownin Figure 1(right). A self-calibrating step during the initialization allows the system toautomatically find the vertical position (origin of the coordinate system). A custom designedcircuit board produces the

The meeting was held at BTEC and had two important outcomes: 1) a generalagreement that a collaboration between ECU and the Capstone Center in the area ofbioprocessing and biomanufacturing would be beneficial 2) that it would be beneficial to furtherplanning for ECU faculty to attend at least one of the Capstone Center courses in order todevelop a better understanding of the format, content, and delivery of the current CapstoneCenter course offerings. Following up on the initial meeting, an ECU faculty member attendeda 2-day course titled “High Performance Liquid Chromatography”.
