Low performance on three laboratory reports has led to instructional improvements,including additional focus in the lecture and detailed handouts. Subsequent assessment showscontinued improvement in skill levels from one laboratory report to the next, and from onesemester to the next.IntroductionTAC/ABET requires that engineering technology graduates have an ability to communicateeffectively (Criterion 3, Program Outcome g).1 The MET program at IPFW includes twocommunications courses and three English courses which develop students’ skills in

between autonomy and creativity in this particular classroom context. The aim hereis not to review the abundant body of literature that exists on the nature and nurture of creativity.Rather, this article seeks to (1) highlight a marked failure in traditional engineering educationalapproaches to offer learning environments that foster creativity, (2) emphasize the importance ofautonomy in the development of creativity, (3) provide an example of an introductory-levelmaterials science course that leverages student choice and control to promote engagement, self-motivation, and creative thinking, and (4) encourage engineering educators to considercurriculum design approaches that foster student creativity.Conceptualizations of CreativityThe
alsoconducted to reveal origins of MSE related misconceptions. Misconceptions that are present inundergraduate introductory MSE students were revealed using the Materials Concept Inventory(MCI). The misconceptions were linked to four distinct categories of K-12 misconceptions inphysical science and chemistry: 1) the nature of crystalline structure and unit cells, 2) therelationship between material characteristics and bonding, 3) material processing, and 4)saturation and super-saturation. These misconceptions were caused by deficiency, fragmentation,ontological, and pedagogical learning impediments. From the comparison and categorization ofthese misconceptions’ origins, we have made suggestions for developing effective misconceptioninterventions and

assessment survey wasdeveloped and administered to students at the end of the semester. The survey recorded thestudent’s perception of the activities relative to each other and their value with respect to thecourse outcomes. The results provided insight to the student’s favorites; what unique or personalopinions were formulated; which activities best enhanced learning; and student suggestions forimprovements.The objective of the Manufacturing Processes (IE314) course is to provide engineering studentswith basic information on materials and processing necessary to change stock materials intouseful, value-added products. The course learning objectives state that the student will beprovided with the tools to qualitatively describe: 1) the workings of a
faculty developmentliterature, “The Muddiest Point” assessment.1 Not surprisingly, the concepts students identifiedare topics that students have historically found difficult in this course (i.e. basis, true stress, errorfunction, slip, lever rule, and polymer structures). However, survey data show that studentsreported only two topics were difficult (i.e. basis and polymer structures). Surprisingly, surveyresults indicate that the majority of students responding found all of the screencasts helpfulregardless of whether they found a concept difficult or not. Other data suggest that the impact onstudent learning could be even greater, as both faculty and students learn to utilize this newresource. Addressing these concerns, in a second iteration of

Notice that the plan isdivided into inside and outside class activities, all of which are thoughtfully designed to addmeaning and content to the course. These activities (a) get students ready or prepared forclass, (b) give them opportunities to practice—with prompt feedback via the Wileyplusplatform—doing whatever it is you want them to learn to do, and (c) allow them to reflect ontheir learning. The objective is to produce a sequence of activities that build on each other. Oneparticular activity was the construction of a poster and presentation of a real life failure event,sample of which are shown in Figure 2. Another activity was for a pair of
insecuring high tech jobs particularly where the reengineering skills are essential.IntroductionThis paper presents a new short course (typical duration of about three weeks), which introducesboth seniors and first year graduate students from Mechanical, Civil, Architectural and Industrialengineering students a concept of reengineered materials. The course is typically divided intothree sessions (one session per week). Each session runs approximately three times in a week,with duration of fifty minutes each. The details of the three sessions are provided below:Session One - Overview of CompositesIn the first lecture of Session 1, students are introduced to composite materials. Students learnthat a composite material is made of two or more chemically
material properties of strength,hardness and ductility. The processes of work hardening at room temperature and annealing aretwo common manufacturing processes that typically change mechanical properties of metallicmaterials. Page 14.663.2Forming operations can be subdivided into hot work at elevated temperatures and cold work atroom temperature. Cold work materials not only change the material shape but also change’smicrostructure and mechanical properties.1 Dislocations move and get entangled at barriers toincrease strength and hardness. As the percent of cold work increases the material becomes sohard that it starts to crack because of low
-based programs and games. The creativity abilities andlearning methods associated with “hands-on” (kinesthesis) teaching methods have substantiallydecreased in recent years due to the availability and allure associated with computer based gamesand teaching programs. The application of kinesthetic learning methods are not as utilized asthey were in the past. Students no longer spend substantial amounts of time creating componentswith their hands, like previous generations, and this may be limiting their ability to comprehendmany metallurgical engineering concepts such as the fundamental concept that relates materialprocessing, microstructure, properties and performance. Figure 1 depicts the interconnectedrelationship between these metallurgical

Examples of the rapid prototyped (RP) links on the pattern board are shown inFigure 1Before testing, the students are given a second homework assignment where each of them has topredict where failure will occur, what the failure load will be and what it will cost to design, test,and manufacture the links. This activity requires them to use mechanics of materialsformulations to solve for the failure loads.DesignFigure 1 shows four of the designed links. One mistake that we made was to remind the studentsto put a draft angle on the edges of their designed
that the instructor hasa much larger scope for instruction than was suspected at the onset of this project and theevaluation system will change accordingly. The questions for these surveys mainlyfocused on students’ prior knowledge of iron and steel science and industry, as well astheir interest in them. Two questions given in the first survey were: Do you know of any steel plants in the area or in the U.S., and can you describe any of the products that they make? In 1-2 sentences, describe your impressions of the steel industry.Two questions from the second survey were: Did the presentation pique your interest in any particular area of ferrous materials engineering, e.g. processing, property testing, or
in recent years were taught by student instructors. Endof the academic quarter course evaluations indicated that the quality and depth of lab instructionvaried significantly across the lab sections.Our university is on quarter calendar system where each quarter is identified by a 5-digit code:first four digits indicate the beginning of the academic year and the last digit refers to the quarter(Fall = 1; Winter = 2; Spring = 3; Summer = 4). Table 1 lists the number of sections andinstructors involved during the last two academic years. Each lab section is limited to amaximum of 12 students although on a few occasions this policy has been violated toaccommodate students with schedule conflicts. Table 1: 0304-344L

The material can change from being fluid to solidalmost instantaneously, the rheology of the material reverting to its original state uponremoval of the field.“Response, which takes only milliseconds, is in the form of a progressive gelling thatis proportional to field strength. With no field present, the fluid flows as freely ashydraulic oil”.1 As a result, MR technology provides fast and infinitely variablecontrol of energy dissipation of industrial and automotive devices.2 This change ofstate has the potential to revolutionize the control aspects of vibration and theresponsiveness of hydraulic power transmission systems. “The application
