Page 12.1283.4Feedback was sought from both students and instructors. The university Human SubjectsReview Committee supported a group, oral interaction. Thus the instructors recorded studentresponses during the activity. The instructors also pooled group data for the Temperature vs.inverse delta time curves. Finally, the instructors reflected on other aspects of the activity.NSF MatEd: The MatEd Program requested activities to support their concept inventory. So theywere

Page 12.1037.6It is an intensive and challenging program. Two students (out of 25 Microelectronic Engineeringstudents) enrolled in this program in it debut. Texas Instruments supported the first student topursue research on aluminum alloy films for micro mirror applications. The student investigatedoptical visible reflection coefficient of aluminum films alloyed with chromium, copper andtitanium, and developed universal dielectric function model4. He was subsequently hired byTexas Instruments on graduation. The second student investigated and developed nickelmonosilicide process at RIT and joined IBM on graduation. Success of these students promptedinterest and enrollment doubled in 2005. The assessment of the program is carried out through

, thestudents were quite used to using the whiteboards to sketch out plans and ideas, as well asdiscussing pros and cons with each other. Since there were so few students in the class,there also appeared to be a fair amount of accountability to contribute in some way. Evenwhen the students divided into 3 different display projects, the students still relied oneach other for feedback and help.While the final designs seemed to be quite simple at first, there turned out to be a varietyof challenges that had to be overcome. The “real world” aspects to the projects and theneed and desire to have the displays actually work impacted the students, as revealed intheir reflection assignments and end of the quarter survey.Metallic TrampolineThe “atomic trampoline

3.4 3.7Scores: 1-Poor, 2-Fair, 3-Good, 4-Very Good, 5-ExcellentThe scores reflect the mean values for the entire class and indicate their level of confidencewith 1 being Poor and 5 Excellent at their ability to apply the design attributes tounstructured problems. In the areas of planning, idea generation, feasibility analysis anditeration it appears that both the freshman and juniors, who have experience with PBLdesign activities, feel more confident in their abilities. Overall the juniors, who have hadthe most experience with applying the design method, demonstrate the highest levels ofconfidence across all of the attributes.The survey data for the freshman cohort is still being analyzed to see if there are anystatistical

broader impacts of engineering, enhances systems thinking, reflects sustainable engineeringpractices, and helps prepare students to make an impact in the global community. Project-basedlearning approaches that emphasize student learning rather than instructor teaching may be a keyto successful development of “global engineers.” Evaluations of project-based courses showincreases in student motivation, problem-solving ability, communication and teaming skills,knowledge retention, and capacity for self-directed learning. Despite these reported benefits,curriculum-wide implementations of project-based learning are rare, probably partly due to thetraditional emphasis on technical content acquisition in upper-level courses and a lack of clearmethods

monitoring of the free- and bound-water rotationspectrum in hydrating portland cement over the frequency range 10 kHz to 8 GHz from initialmixing to several weeks cure, using broadband Time-Domain-Reflectometry (TDR) DielectricSpectroscopy and an embedded capacitance sensor. The result is an improved understanding ofthe hydration process from a molecular dynamics standpoint, and a foundation for using TDRspectroscopy as a powerful tool for investigating the hydration process in cementitious materials.In addition, the ability to interrogate the sensor in the time domain and extract information fromthe direct reflected transient can provide a novel and robust cure-monitoring method usable inthe field.The teaching component consists of integrating

It is seen that the companies thatsponsor Kettering University students represent a diverse cross section of U.S. industries. Thechanges that have been taking place in these industries, their need and the challenges faced bythem are immediately reflected in Kettering University’s classrooms as the students bringvaluable experience after 24 weeks of work experience per year with their corporate sponsor.This composite materials course will fill a gap between our current curriculum and the need fromour corporate sponsors, and provide our students with hands-on design and application skills incomposite materials.2.

Theprimary goals of the program were to develop a new formulation for the writing assignments thatwas more reflective of and appropriate for real-life engineering situations, to clarify the iterativecommunication loop between student and teacher regarding the effectiveness of the writing, andto create an evaluation process that would promote consistency among multiple instructors.The writing assignments were reformulated in the form of contextual assignments, modeled onreal-world settings in industry, and covering a range of

which is what I like. I like the pre-quizzes because that means that I actually have to read the chapter before taking them.”Another supplementary tool is the external links section of Blackboard. Each topic covered inthe course has links associated and the students are encouraged through extra credit, or in-classquestions to visit those sites. The classroom experience involves board lecture, team quiz-bowltype questions and partner work. At times PowerPoint slides are used to supplement theinstructor’s board lecture and this also serves to keep the learning activities varied.

, 17% chose saturated,and 8% did not respond. The responses on the three parts of Question III as 75%, 92%, and 81%correct are moderately good scores that reflect good, but not complete understanding of theconcepts of unsaturated, saturated, and supersaturated on the phase diagram. The scores werelower than for posttest Questions I and II, which indicates that there was not full conceptualtransfer from the solution understanding in chemistry classes, supplemented by instruction in thematerials engineering class, to the new context of phase diagrams. Additional probing, possiblywith interviews or focus groups, will be necessary to better understand student thinking todevelop more effective teaching on the subject of phase diagrams.Summary and
