involves an industry-sponsored event where the entire student cohort participates in a robot competition.For a number of years, anecdotal evidence has suggested that the course sequence has significantpositive impacts on student experience throughout the curriculum. It has been postulated thatthis experience results in significant knowledge gain, reinforces their decision to pursue a careerin electrical engineering, and builds camaraderie amongst the student cohort. A study wasconducted to better understand these potential impacts. Part 1 of the study analyzed grades in theproject course sequence and compared them to another course sequence that also occurs in thefirst and second year of the curriculum. Part 2 was a survey in which students and

components are used to augment the courses in order to enhance students’mastery of the subject matter and its applications. Usually, the capstone design course at thesenior level allows students to synthesize what they learned and exercise their creative ability.The main goal is to facilitate an environment for students to walk through the entire designprocess from the formulation of ideas, through implementation, test and validation. There aremany reasons that might contribute to the difficulty faced by the students in their ability tosynthesize and be creative. Two specific contributing reasons that we identified and attemptedto address are (1) insufficient critical thinking exercises and (2) lack of self-motivated activitiesunlike the cook-book

example, a set of three PIs are defined for each SO, theevaluation effort will be at least three times more time consuming.To further improve the assessment model used, the traditional rubric-based assessment model isaugmented by classifying courses in the curriculum to three levels: introductory, reinforced, andmastery. It is customary for the traditional rubric-based assessment model to include only thecourses in the mastery level for the program outcomes assessment. The drawbacks of lookingonly at courses at the mastery level are: (1) lack of information needed at the lower level toidentify the root cause of the deficiency when the symptom occurs at the higher level courses; (2)lack of the mechanism to compute a clear indicator such as the

They also had not yet taken the Digital Systems Designcourse.Design Methodology The WIMP51 design was based on the available block diagram and instruction set7,shown below in Figures 1 and 2. Some additional state machine information, including the threemain states, in an instruction cycle, was also available7. In order to complete the design, in theallotted time, minor changes in the internal organization (missing ‘PSEN’ as seen in Figure 1)and the instruction set (Figure 3) had to be made.

-long senior design project. Theobjective of the design was to safely launch a small projectile at a muzzle velocity of 350 meters/secondfrom an approximately 1-meter long barrel using capacitor-based energy storage limited to a maximumof 450 VDC. The projectile needed to be fired into a catch to facilitate demonstrations inside a laboratoryenvironment. The project was also constrained by a $5,000 operating budget and access to parts availablein the laboratory. The three electrical engineering students and one systems engineering studentself-selected the project and decided how to divide tasks, structured and managed a schedule, plannedbudget use, and leveraged in-house machine shop capabilities.

of online solution manuals, ever more intelligent search engines,and repositories containing solutions from previous course offerings, the utility of traditionalhomework as a form of summative or formative assessment is increasingly unclear 1 . Traditionalhomework models reward correct answers, incentivizing students to consult online sources foranswers; studies have shown that 90% of students consult (questionably obtained) online solutionmanuals when completing homework 2,3 . While there are means to counteract this somewhat (e.g.,creating new problems or variations each course offering), it would seem that with the rampantuse of solution manuals by students, traditional graded homework assignments are an unreliableindicator of student

Reduce or eliminate homework plagiarism: this is achievable since the final homework grades are not going to assess how well the student attempted the homework but will assess how well they graded it and reflected on their mistakes. This will totally flip the homework from being an assessment tool to an active learning tool. 2. Improve the effectiveness of the homework within the learning process: this is achievable since homework is honestly attempted. In addition, the process of grading the homework requires a good grasp of the solution, which is only possible through outside-the- classroom learning. 3.

Educational research shows that when students passively receive contentknowledge from instructors in large lecture halls, meaningful learning seldom happens. On thecontrary, rote learning is the result of such traditional teachings.

ECE programs lose a good number ofstudents to other disciplines and programs due to its supposed ‘highly theoretical’ nature, and acommon misconception that ECE is exclusively about electricity and electric circuits. Manyundecided students are torn between their love for building gadgets, and their need to acquirehighly in-demand skills such as programming and creating applications.

Technological, economic, and social pressures are reshaping higher education, butthere is little consensus about the future. IEEE created a Curricula and Pedagogy Committee(CPC) and charged it with forecasting the future of ECE education and to makerecommendations regarding roles that IEEE will play in preparing for and crafting that future.To gather more information from members of the engineering education community, thecommittee conducted a global survey.

The choice of courses for course-embeddedassessment is guided by two principles: (1) each Student Outcomeis assessed with student work in a benchmark course, and (2) onlyrequired courses, not elective courses, in the curriculum areselected as benchmark courses.Assessment of a benchmark course is conducted with the followingin mind: (1) assessment of student work measures the extent towhich SOs are being attained, (2) it is not necessary to use all ofthe student work to assess an outcome, and (3) outcomesassessment is

This lack of formal prior knowledge hasthe potential to prevent students from being able to assimilate new material they come in contactwith when instructed about electric circuit concepts. Other impeding factors reported have beenthe influence of students’ prior misconceptions, the abstract nature of the content, inadequateinstructional strategies to provoke conceptual conflict and inadequate preparation of studentsfrom pre-requisite courses. However, a gap that still exists is the direct interaction between: (1)students’ prior knowledge, (2) the types of learning activities and (3) the design of the learningenvironment fueled by the decisions made by professors on how to teach circuit concepts.This

Because most students understandohm’s law, these modules allowed students to focus on understanding how to use the ADB.Students are able to quickly build the circuit as they were forced to familiarize themselves withboard connections and computer interface. Once the students are comfortable with the boards, theyare able to move on to modules that reinforce the concepts covered in class. By the third module,students

of asynchronous pipelineddigital circuit structures that are called self-timed [1]. The dynamic energy dissipation isreduced in this realization, relative to synchronous implementations, because circuit timing andcontrol is event driven and all clocks are generated locally. The performance of these circuitscan exceed synchronous realization because it is based on the average intrinsic timing of thecircuit instead of its worst case timing that is used to set the clock frequency in synchronoussystems. The circuit design process used to determine the device sizing in self-timed circuits istypically the same as that used for synchronous realizations [2, 3, 4].

IntroductionWhen one compares today’s students to those of earlier generations, the differences are striking.Yet the way most faculties teach electric circuits is essentially unchanged since the middle of thelast century [1]. Electric circuits courses are mostly taught through “analysis”. Too often, thefocus lies on writing and solving sets of simultaneous equations based on Kirchhoff’s voltageand current laws (KVL and KCL). In practice, this leads to a circuit methodology
