students to focus on surface details andspecific solution methods but miss the bigger picture or underlying concept. To draw an example Page 26.1618.3from math, students are taught in high school algebra to multiply a pair of binomials, e.g.(a+b)(c+d), using the “FOIL” method – First, Outer, Inner, Last. Most students fail to realize thatthis is a specific application of the distributive property of mathematics, and when faced with asmall variation, e.g. (a+b)(c+d+e), they are lost. In an engineering setting, a student may be veryadept at applying mesh analysis to find the currents in a branched resistive network, but thatsame student will often

[long pause] Person B: Because the rate that the water’s flowing through the pipes is going to provide a force on the [pauses, laughs]. So you have a pressure, you have a velocity, and you have an elevation head, but I don’t [pause]. Everything has to equal, so if you increase your velocity on one side, then that would have a lower pressure, but they’ll be [pause] I think it [pause] yeah, I honestly don’t know.

Moreover, as previously indicated, the implementation of an inductor-gyrator is preferred in lieu of an inductor. We implement the Chua’s diode schematic presentedby Ref. 7 and the inductor-gyrator presented by Ref. 5 as shown in Figure 2. In most literature,the instructions for building a

The Atmega328microcontroller allows the user to add multiple sensors and actuators to the robot. The robot alsohouses a Raspberry Pi, which acquires commands from the user via a network connection andsends serial commands to the on-board Arduino. See Figure 4(b) for the fully assembled leggedrobot. Once the server running on the Raspberry Pi receives the user’s C-code, it commands theArduino via UART serial communication protocol. Upon receiving serial messages relating tothe robot motion, the Arduino board executes the motion sequence to appropriately control theservo
math course that you have completed? Do you have an engineer in your family? When were you exposed to Civil Engineering? The figures below indicate the freshmen student's to the survey. It is clear from the resultsthat a majority of the students surveyed were mainly interested in structural engineering andindicated minimal understanding and/or knowledge of the other sub-fields within the CivilEngineering profession as shown in Figure A. In addition, most students became engineersbecause they liked the sciences or liked to construct things as shown in Figure B. Since manystudents are from first generation college families, they had limited opportunities to meet withother engineers, practitioners, or mentors. This was clearly
and that feedback given to students must beinterpreted by students themselves and internalized before it can impact on students’ learning andfurther study9-11. Guided reflective thinking can often be used to guide students through self-assessment activities. Guided reflective thinking is a systematic way of thinking about one’sactions and responses such that future actions and responses can be improved12. Dewey13 describesa reflective operation as having two essential elements “(a) a state of perplexity, hesitation, doubt;and (b) an act of search or investigation directed toward bringing to light further facts ….”. Otherestablished approaches for promoting reflective thinking include prompting students withquestions and worksheets to identify
operation point will be at the intersection of the power-voltage profile of theload and the PV array. If the operation point is at the maximum power point (MPP), maximumpower from the PV array will be achieved. However, since the MPP is irradiation dependent,installation of a power regulator and continuous MPP tracking control technique are essential. Figure 1: Electrical characteristics of a PV panel in different illumination. B. Energy Storage Systems Since renewable energy have intermittent characteristics, energy storage systems arenecessary for a high penetration of energy into a power system. Energy storages are also ofcritical importance in power systems to meet peak demands and to improve the reliability of thepower

Thus, the evolution of course structure has steadilymoved from lecture intensive with graded homeworks to incrementally broader adoption of thestudent-led example exercises with the final iteration including a flipped classroom.

This categorical dependence is shown for the 2012 cohortin Figure 2 below.

the simplicity to be built by students over the course offive semesters. The research is designed to test two hypotheses: 1. A long-term design project that integrates knowledge from multiple courses strengthens student knowledge retention. 2. A large-scale design project requiring tools from many courses improves student problem-solving and design skills.By integrating five semesters of the mechanical engineering curriculum into a cohesive whole,this project has the potential to transform the way undergraduate education is delivered. Beforeand after testing is being conducted to assess: a) Change in retention between courses and b)Change in student problem-solving and design skills.The centerpiece of the hybrid powertrain is

It is created through the design,facilitation, and direction of cognitive and social processes such that personally meaningful andeducationally worthwhile learning outcomes are realized. See Appendix B for a chart of courseactivities.Ensuring educationally worthwhile outcomes in engineering education requires usingpedagogical methods that are instructional themselves.

between the grades of Non-WRM majors and WRM department majors. However, given that the WRM students enrolled in the class in any semester vary from none to three compared to the high number of Non- WRM majors, it is statistically not viable to come to a definite conclusion about the performance difference between these groups. In the near future, the situation is expected to remain the same as the WRM department is comparatively smaller than other departments. b. From Figure 2, it can be seen that there was a definite increase in student enrollment in the post Fall 2009, after starting to implement Connect2U except for Fall 2013. While the class size was defined as 25, in some semesters, given the needs

growth and application of innovative thinking andbehavior in both student and practicing engineers has become a mantra across all typesof organizations (National Academy of Engineering, 2005; National Academy ofSciences, National Academy of Engineering, & Institute of Medicine, 2007; NationalGovernor's Association, 2007). However, societal confusion exists about the definitionof an innovation (Ferguson D. & Ohland M., 2012), the process of producing aninnovation, and the behavior required to be a successful innovator as an engineer(Ferguson D., Cawthorne J. , Ahn B., & Ohland M., 2013). The research question thatguided our investigations started with the engineering innovator interview study and thatcontinued through the Delphi study

switches are connected together via theswitch matrix on the bottom of the diagramThe OKCET laboratory has a need for a matrix capable of routing between a large number ofdevices with the possibility of expansion into the thousands. Another requirement is the ability toachieve multiple simultaneous connections for testing different pieces of equipment at the sametime. For these needs, in an A x B matrix, the number of rows, A, needs to be a smaller numberrepresenting the number of simultaneous connections allowed; whereas the number of columnsB, needs to be a larger number representing the number of devices that would be able to interfacewith each other.
