Table 1 shows the percentage of students needing to repeatStrength due to low grades, along with the repeat rate in all other MET courses. 1 Based on a 20%mean repeat rate, Strength is apparently the hardest course in the curriculum. The table does notinclude students who withdrew from courses because of low grades. When withdrawals areincluded, the repeat rate in Strength runs between 18% and 35%.

harmonic loadings is employed for this purpose.Proportional loading is defined as any state of time varying stress where the orientation of theprincipal stress axes does not change with respect to the axis of the shaft. Non-proportionalloading is defined as any state of time varying stress where the orientation of the principal axes Page 23.678.2changes with respect to the shaft axis. The students study the “proportionality” of loadings usingMohr’s circle for four specific cases for a shaft under combined bending and torsion, which are: 1. Time harmonic bending moment and time harmonic torsion that are in phase. 2. Time harmonic bending

One way that this needfor energy curricula is being addressed is through programs in energy storage for stationary andvehicular applications2-5.The School of Engineering at Grand Valley State University is preparing students to compete forjobs in the advanced energy storage (AES) field by developing a three-course certificate inadvanced energy6. To complete this certificate, students may choose three of the following fourcourses: 1) Electrochemistry, 2) Alternative Energy Systems and Applications, 3) Materials forEnergy Storage, and 4) Electric/Hybrid Vehicle Battery Systems. This certificate is available toundergraduate engineering students earning a Bachelor of Science in Engineering (B.S.E

passivecontent reception.1 2 A common theme of these “flipped classroom” approaches is that studentscomplete activities before class focused on content delivery—assigned readings or watching pre-recorded lectures, for instance—freeing the instructor to spend class time working with studentsin various ways that emphasize active participation.3From an instructor’s point of view, the flipped classroom is appealing because it provides astimulating classroom environment. Such perceptions, however, cannot show whether such achange in methodology is actually more effective than traditional lectures. In the fall of 2011 theresearch team embarked on the present study designed to provide both quantitative data onstudent learning gains and student perceptions of

- presentations.IntroductionPOGIL is the acronym for Process Oriented Guided Inquiry Learning and was developed at the Franklinand Marshall College to teach general chemistry [1]. Research results in the area of cognitive science onhow people learn are the basis of POGIL [2]. This basis consists of 1) formation of a cooperative learningenvironment where students become interdependent and supportive of one another in understanding classmaterial 2) questions that provoke students to think about new class material based upon previousknowledge that they may have. This is called “Guided Inquiry.” It is significant as it providesopportunities for students to integrate new information with old and resolve misconceptions that they mayhave and finally 3) students think about their

A task that provides some hurdles considering these words came inthe wake of growing concern for the lack of students pursuing degrees and careers in STEM (Science,Technology, Engineering and Math) related fields. According to the National Center for EducationalStatistics, students who perform at or above the proficiency level in 8th grade science is fewer than 1 outof

In addition, discussion of sustainability inevitably involvesmultiple disciplines, so the discussion is enhanced with multiple perspectives.Sustainability Education for Materials EngineersTo evaluate the educational needs related to sustainability, The Metals, Minerals and MaterialsSociety (TMS) included questions on the topic in a recent member survey1. One portion of thissurvey asked respondents to rank the desired and actual proficiencies on several sustainability-related topics. The results, which are summarized in Table 1, show that the most important topicis energy use and efficiency, followed by recycling/reuse, life cycle analysis and corporate socialresponsibility. In all cases, the desired proficiency is lower than

activity that used material selection as the primary driver fordevice performance. This is the ‘bridge’ that we focused on, allowing a general ‘design’ activitybe applicable to multiple disciplines.Another challenge concerned the assessment of design skills. Based on previous work3 a metricwas selected. The metric is termed “RADD”, and has been used each quarter for over five years.The metric targets four areas: 1)Requirements, 2)Analysis, 3)Design, and 4)Drawings (RADD).The metric has been adapted for use in assessing different media. For example, the initial usewas to assess documents such as engineering proposals. Then the metric was modified to assesspresentations, such as Design Reviews. For this effort, we chose to create a RADD metric

Student's choices, persistence,and effort to learning contexts independently and in groups are affected by their motivational andaffective beliefs1. Previous studies have shown that two points govern student motivation: 1) thedegree to which students believe they can complete a task (self-efficacy) and 2) the value thestudents place on the learning task2 . More specifically, college students must also perceiveadded benefit their personal futures3,5. The degree

The article raised concerns about the safety of polycarbonate babybottles, and recommends that parents dispose of them as a precaution.Additionally, for the current work the authors experience in developing case studies developed thefollowing loose guidelines to give the students: 1. tell a story that has a beginning, background, a middle, and a conclusion. 2. trigger your peers interest. 3. have real characters to identify so that the student can role play one of those characters. It helps bring out the subjectivity of decisions and how credibility of a person

surface. Crystal orientation changes of between 1 to 10 degrees create very thin(nanometer wide) regions called low angle grain boundaries (LAGBs), and where they occur,they separate a crystal into subgrains, or crystallites. High angle grain boundaries (HAGBs), withmisorientation between 10 to 15 degrees, are a discrete change of crystal orientation. Theseregions are defined as the demarcation between grains. Grain boundaries render a material apoly-crystal. The long-range collection of grains, grain boundaries and other defects in a materialsample are collectively termed “microstructure”.It may confuse novice learners that HAGBs and LAGBs may each be detected or imaged bysome characterization techniques and not by others. For example, optical
