enough rise time, so a simple switch is constructed from touching the W1 wire to theRS lead to create a step excitation. A long coaxial cable was utilized to allow the voltage ringing,which is due to the low oscilloscope bandwidth, to die out and reach steady state in betweenroundtrips of a transient. Figure 2a shows the oscilloscope capture of a transient on an open-circuit load ( RL ). An input voltage divider is apparent (2.5V transient launched on thecable), and the cable is shown to have a roundtrip delay of approximately 200ns, after which thereflected wave reaches the source and changes the input conditions. Calculations from themeasured voltages indicate an impedance of Zin Zo 50 before the reflected wave reachesthe source, and

Felder and Silverman4 argue that though students allhave different learning styles, and a small number of techniques can meet the needs of moststudents. They recommend using material that emphasizes practical problem solving andfundamental understanding. They also discuss the importance of reflective learning (along withactive learning). The author’s initial vision was to bring a can crusher to class and let thestudents answer some questions about mechanical advantage, thus extending familiar contentfrom their Statics course (drawing free-body diagrams, balancing forces and moments) to an ideathat was brand new

This indicates a need to analyze networks starting attheir emergence and onwards. Effectiveness of any network and the definition of effectivenessare, in addition, context specific, and so too should be the approach for evaluating networkeffectiveness30. This more progressive approach, when combined with social network

In the research memos, the lead researcher also reflected on theseinterpretations, noting her own thoughts, feeling, and preconceptions about the phenomena beingstudied.After all of the 20 interviews were completed, the researcher defined an initial set of conceptsusing the memos from the interviews as well as the transcriptions.

choices; so when we see students whoare not motivated to learn, a reasonable first hypothesis is that their task value motivation is low.This is a hypothesis shared by much of the engineering community. A very commonpresumption regarding students’ low learning motivation is that they simply don’t know thatengineers have use for writing skills, that “real” engineers write; and if only they did, surely theywould apply themselves in their writing classes. We can see some fleeting evidence of this kindof unmotivated student in qualitative data. For example, in case studies and interviewsengineering students have reported that they don’t see writing as important 1, or they viewwriting as incidental to the real work of engineering, reflecting cultural
. The greater the specificity of the task and theclearer the expectations, the more likely students will accomplish it and/or meet the expectations21, 22 . These objectives can serve as study guides for exams, as was done in this course22.Format of the 2015 CourseThe course was scheduled for 75-minute lecture periods on Monday and Wednesday, with a 110-minute lab period on Friday afternoon. This change was important, as it allowed for betterdistribution of classroom activities and more time for student reflection and learning betweenperiods. The instructor also adopted a different textbook23 with more narrative, and the studentevaluations reflected high satisfaction with this book. However, it was necessary to supplementwith more updated
homework assignments, midterm and final exams,and a final project. The final project required students to propose an electromagnetics-relatedproblem they would like to explore computationally, develop a computational model for theirproblem using MATLAB or a similar software package, and present their results in the form of ascientific journal paper. Example problems included finding a way to reduce lossy reflections offsolar cells and determining the maximum distance a railgun can launch a projectile.The professor perceived a few problems in this previous version of EENG 386. Students wouldfrequently clamor to see more example problems and applications during class time. While aclear attempt was made to devote time to these aspects of the course

Thesoftware allowed the teams to program the robots, collect the data, plot a graph and come upwith a hypothesis about the time the robot would require to traverse an arbitrary distancespecified by the faculty and/or an undergraduate student leader. The teams who did the mostaccurate predictions won prizes. After the competition ended time was allotted to reflect on theexercise and the lessons learned.In the last part of the orientation, students watched some highlights from videos related to robotapplications previously collected by the faculty and the undergraduate students planning theorientation. A magazine article15 related to humans and robots interaction was provided as areading. Freshman engaged

Groups would meet not only on their own out of class to complete a courseassignment, but additionally in-class to apply the concepts they learned in the online modules.For example, groups would spend time on plan reading exercises and the instructor was able tospend time providing feedback to each group.4.3 Data gathering and analysis. Data was gathered through a reflective journal kept by theinstructor and a survey administered quarter into the semester and towards the end (AppendixA). 4.3.a Instructor notes: Given the new approach to teaching the instructor kept weeklynotes about the

These experiences are often positive, especially when students have the opportunity tosolve novel but challenging problems, navigate their own processes, critically reflect on theirexperiences, and receive appropriate levels of support and scaffolding. This study furtherexplores the role of scaffolding on innovation and non-innovative projects through the lens ofVygotsky’s theory of proximal development. Ten engineering seniors participated in

In addition, theysubmitted pre- and post-surveys, a curriculum vita, teaching, research and service philosophies,questions for panels, course segment reflections, and e-portfolios. By the end of this seminar,students were expected to (a) describe realities of the academic job market, (b) articulate theirprofessional aspirations and competencies, and (c) develop materials to compete for and succeedin the academic job market.This seminar and its evaluation emphasize development of doctoral students’ understanding offaculty

For example, recent modifications to the ABETEAC criteria specific for civil engineering programs seemed to reflect consensus that ethicseducation may have been insufficient.8 In order to provide greater clarity to understanding thescope of both micro- and macro- ethics education, a national study was conducted. © American Society for

These kinesthetic/tactile activities can be directly connected to deeper thinking aboutthe how and why of the results.14,15 This type of activity reflects a fundamental aspect of theengineering modeling process where an engineer observes a physical phenomenon, e.g.mechanical behavior of a material, and develops ways to quantify the behavior to use in apredictive manner in the future. It is important to note that in this paper we use the termkinesthetic learning or hands-on activities to mean a physical activity that is meant to teach aconcept and develop a deeper understanding of the material, not just the performance of a skill orobservation of a phenomenon.The scope of this paper focuses on the conceptual

By introducing electronic assembly, analysis, andrework, in the context of making sound and music, we aimed to inspire students to connect theirinterests, hobbies, and passions with their chosen field of study, even if they are traditionallyisolated practices11. We hoped to draw a diverse audience that reflected the varying perspectiveson these practices, and encouraged high school outreach and pre-college involvement.

identity are allowed to naturally separate themselves in this picture of theexperiences of the individuals. For example, students may be traditionally identified as comingfrom one or more underrepresented groups in engineering and, hence, assumed (wrongly) tohave some “different” attitudes about engineering, without attention to the diversity within suchgroups. Instead, the TDA approach allows for the “normative” or popular attitudinal clusters tobe first identified in the data, and then traditionally underrepresented individuals will appearwithin these attitudinal clusters in a way that is faithful to each individual's response (e.g., atraditionally underrepresented student who reflects dominant attitudes towards engineering willappear in that
concepts inNewtonian mechanics.Acceleration is a concept of crucial importance, which is connected to velocity and force inkinematics and dynamics, respectively. However, this concept is rarely used directly in everydaylife, and there is a lack of vocabulary to describe it. In the specifications of automobiles,acceleration is not listed directly; instead, it is described in the acceleration time from 0 to 60mph. This example reflects the definition of acceleration, which connects the two relatedparameters: the change of velocity and the time interval. With the unit converted, students canfind the acceleration easily from the provided time interval.The concepts of centripetal acceleration and force are a little challenging for most students
studied innovative teaching methodology inthe past forty years. Though, the definition of experiential learning has changed quite some overthe years, the main motivation stayed the same since was first defined by Dewey (1971):“thestudent learns by doing”. Therefore, if the students are immersed in an environment where theyare mentored to reflect, collaborate, and assess (Qualters, 2010), learning may then become alifelong process. According to Kolb and Kolb (2005), experiential theory allows students toapproach learning as a holistic process of adapting to the world. Hence, they, not only comprehendinformation more effectively, but also take active roles in creating further knowledge throughsynergistic interactions with their environment.One

Some students responded that they have changed theirphone usage because of what they learned in the class and as a consequence increased theirproductivity and sleep time. Other students reflected on how their projects have made them muchmore mindful of their personal contribution to their project topic, such as waste disposal.

Semi-structured interviews (n=20 total) were conducted at the beginning and end ofthe school year to identify and characterize teachers’ perceptions of engineering design,expectations and reflections of task implementation, and challenges they experienced throughoutthe year. Analysis and interpretation of teacher interviews involved the use of grounded theory.18During this process, members of the research team focused on identifying indicators of conceptsand categories that fit the data.

However, she also chose to provide one-on-one mentoring to a fellow teacher from herschool by meeting with her and explaining the pedagogies associated with the program. Thatsame teacher, BF, decided to apply to the program, was accepted, and now serves as an advocateof program pedagogies throughout Felicity-Franklin.BF made a tremendous impact on one particular science teacher in her rural school throughprofessional development. She mentored “Holly” through the process of creating andimplementing two engineering design challenge units and reflected upon the experience: My first

Two of the clinicalprojects, Otolaryngology and Anesthesiology & Pharmacy, were more experimental-focusedproject than design focused project. By experimental focused project we mean the projectrequired more experimental design and analysis rather than the building of a prototype.

The honors students on theseprojects, five of the eight students, were tasked with writing the new research manifesto as theirhonor

These categories relate to People, Experiences,Technology, and Other Influences. The “Family” section of the People category distinguishesbetween simply mentioning a family member and mentioning that a family member is anengineer or does related
who do not get facultyinput on homework solutions, may not ever be taught how to present an understandable technicalsolution. There is no doubt that online teaching tools are beneficial and that students perceptionsand interactions are positive.[2] Some students, at the moment of the interview, state that theyprefer online homework systems. However, these students are NOT surveyed at a later date andasked to reflect on their freshman learning experiences. Although many studies have investigated the use of online homework systems in math [3],science [4–6], or engineering [3,7–10] courses, few have assessed the ability of a student to present alogical solution during the course. Authors in these studies usually correlate homework grades

In describing how she would identifywhat needs to be and can be done related to a particular problem, Olivia referred to “whateveryone would say to do” (a literature search, in this case), which highlights again an emphasison what others might do in a given situation, but is also a rather simple answer that seems tosuggest a straightforward, “correct” way to address a problem.Category 2.

Through the dedicated curriculum, the theorycourses were specifically designed to accommodate students from different undergraduatedegrees and real-world experiences. The project courses, tightly integrated with the theorycourses, accommodate the variety of directions the students may take. The dedicated space andassociated 3D printing technologies were designed and continue to evolve to support thecurriculum. And the dedicated faculty are aware of the many moving parts of the program,allowing for “real time” adjustments to reflect what is happening in technical and businessarenas.What

The necessary deductive-style teaching of accepted engineering design steps Designettes in Capstone: Characterizing the Impact of Early Design Experiences in Capstone Education with Emphasis on Designette Project Choiceshould be balanced with the inductive learning of the students. The challenge lies in allowingthe experiences of the students’ inductive learning to occur with enough time to reflect and buildtheir cognitive framework.Finally, a look at the Kolb cycle (Figure 1) and its application to the design curriculum andcapstone program could be informative. The Kolb model is characterized by a cycle that beginswith concrete experience, proceeds
