a complex series of skills on the part of the students includingskills in mathematical modeling, idea generation, experimental design, and written and oralpresentation. The capstone design process requires the students to generate design concepts andspecifications in response to real-world, open ended problems that may be ambiguous andinvolve a number of systems and a large degree of uncertainty.1 Given the difficulty in teachingthese design thinking skills, Dym et. al. discussed a number of methods for approaching designeducation with the idea of providing continuous improvement in the pedagogy. One of theirsuggestions was to attempt to bring design thinking into all parts of the engineering curriculum,starting with cornerstone design

A set of six guiding principles fordesigning lab exercises are presented. The principles are illustrated in the context of anundergraduate laboratory course in Digital Signal Processing where the pedagogy has evolvedover four years. Changes to the labs were driven by the desire to motivate students’ engagement,improve

instructors. This publication provides quick, easy tounderstand guidance on each of the five phases of the ADDIE model. 1. Analysis – the audience is identified during the analysis phase. The essential outcomes of the training are identified in this phase, sometimes in conjunction with the participant, but more importantly the employer. During a metrology trainer session held in Mexico in 2012, several metrology instructors expressed frustration with the diversity of student knowledge level and level of experience of students attending their courses. A quick review of their metrology course descriptions resulted in identifying an audience that was much broader than they ideally wanted in each course. 2. Design

To provide students a more coherent and cohesive view, we created and are delivering amulticourse curriculum-integrated engineering project that permeates and unifies five requiredclasses within our undergraduate curriculum: 1) Freshman Design, 2) Dynamics, 3) NumericalMethods, 4) Fluid Mechanics, and 5) Thermodynamics

A progressive refinement of studentexperimental design abilities was embedded throughout the three course series (Figure 1). Withrespect to the cognitive apprenticeship model, in the sophomore-level course there was a majoremphasis on modeling and a minor emphasis on scaffolding to provide a strong framework forstudents to build their experimental design skills. In the junior-level and senior-level coursesthere was more emphasis placed on the scaffolding and coaching elements of

The purpose of thissystem is to provide a unified educational platform with which students can experience a widerange of serial-manipulator configurations without the need of multiple hardware setups.1. IntroductionA broad spectrum of approaches has recently been suggested by educators to effectively exposestudents to the field of robotics. A traditional approach is to have students interact with thephysical systems, and perform tasks and experiments designed to teach them the fundamentalaspects of robotics, both for robotic manipulation [1] and mobile robotics [2]. A shortcoming ofinteracting with the hardware, however, is that students only get

10 groups. A more ideal ratio is one to five. • Provide a fall-back for students who do not complete the lab during class. Allow them to complete the lab during TA office hours or open lab hours. This fall-back removes the panic that some students feel while trying to complete the lab during the 50 minute period. • Assign course credit to the lab to motivate students to come to class and to participate fully in the lab.

more, while coming reasonably close to their desired  Q . In their second design( f o = 7.23 kHz and Q = 2) , students typically come very close to meeting the desired resonantfrequency and  Q specifications on the first try. This creates a teachable moment as studentsreflect on their failure in design #1, and their success in meeting specifications in design #2.First our students calculate a parameter we call “ G ”, which is the gain-bandwidth product of theop-amp relative to the desired resonant frequency. Using this calculated value G , they employgraphical techniques early in the design process to predict how much the closed-loop transferfunction pole locations will shift from the desired locations because of a finite value for G

, engineering design processes were represented as a flowchart, such as theone shown in Figure 1. Although some researchers argued that important factors, e.g. teamworkand communication, were missed in the flowchart approach, Mosborg et al13 found in their studythat most of participating practicing engineers basically agreed with the model shown in Figure1. Thus, the flowchart in Figure 1 remained in this approach and the activities in the proposedproject were grouped based on this six-stage design procedure.The project proposed in this approach was course-related. Hereby, its topic should be within thescope of the course contents. For many years, control-related topics have been included inundergraduate engineering curriculums. Traditionally, they

for the first DSP course or the combined ASP and DSPcourse, it is not necessary that we list it as an additional prerequisite.C. Software RequirementTo design, analyze, and simulate the DSP algorithms, MATLAB programming is required; thisrequirement was enforced in the previous signal processing course. In addition, MultiSIM will beused to verify different filter design.As a summary, the DSP course needs the prerequisites as listed below: 1. Analog signal processing 2. MATLAB programming and MultiSIM simulation.III. Course Content and the Associated Real-Time ProjectWe have divided the course content into two portions. First, the DSP fundamentals were covered,such as the sampling theorem, the z-transform and z-transfer functions, the

Technology (MET) program. Most students are juniors entering the core sequenceof classes in the major. Many of the students in this fall quarter thermodynamics class will betogether on graduation day, and they come together for the first time in this class. Thoughstudents may have touched on many thermodynamics topics in Physics and Chemistry classes,this is their first engineering thermodynamics class. The current lab activities have evolved fromthose that were developed in the late 1980s and outlined in a paper by Kaminski (1) in 1995.In order to keep students interested and engaged, efforts have been made to make the activitiesrelevant to everyday life experiences. In some of these labs they must make and state engineeringassumptions to complete
