perceived little value in exit tickets, which are generally designed to develop criticalmetacognitive skills and improved self-efficacy.These challenges are neither new nor unique to the current course. In fact, these are topics wellknown and widely discussed in the educational literature.13,15 It is the plan in future POGILimplementations to move the course towards a mastery driven rather than performance drivenassessment strategy. Specifically, the goal will be to reduce reliance on a few high stakes examby instead providing multiple paths, activities, and opportunities for students build self-efficacyand demonstrate mastery of the stated learning objectives. This approach is particularly attractivein a large format classroom, where managing make

The science classes that high school students,college freshman and sophomores take typically present collections of theories and laws usingtechniques that do not foster creativity, experimentation and curiosity. As a result, studentsincreasingly fail to pursue careers in Science Technology Engineering and Mathematics (STEM).For the past 10 years the number of high school seniors who plan on entering an engineeringcareer has dropped more than 35%.1 Additionally, attrition rates of engineering disciplines havebeen as high as 50%,2 and minority students have been shown to receive less than 8

Additionally, theproject provided students with an opportunity to practice their public speaking and presentationskills through the ‘poster session,’ an important aspect of their growth as a STEM engineeringgraduate.In the future, the instructors plan to explore pathways to have the material’s project centeredaround a societal cause (such as a local community-driven social project) or an actual case-studyproblem in collaboration with the local materials and manufacturing industries. The motivationbehind this approach is to give students a project assignment that will help the community
instruction on the “Introduction” section of the lab report. Instructions on Materials andMethods, Results, and Discussion were all one week apart, and occurred when studentssubmitted drafts for labs 2, 3, and 4, respectively. Focused instruction on references andappendix sections is part of the future implementation plan. The purpose of this strategy istwofold. First, focusing on one component of lab report at a time allows the students to bettergrasp the material. Moreover, receiving these instructions as they continuously write lab reportshelps them apply the received instructions more effectively.3.2. Reviewing Samples as a GroupThe focused instructional time was accompanied by reviewing samples of effective andineffective writing about the same

Spring 2016 semester, the author brainstormed variousalterations that can be done to the labs to further develop students’ understanding of conceptslearned in the course. A plan was put in motion to incorporate more laboratories to allowstudents more “hands-on” experiences. Additionally, it was decided to create a laboratoryhandbook, with pre-labs, for students to complete before performing laboratory testing. The goalwas to have the new labs and handbook ready for the Fall 2017 semester.Before the implementation of the VR enhanced laboratory experiments, students in AppliedStrength of Materials were taught how to perform the laboratory experiments via the“traditional” method. As can be seen in the flowchart in Figure 1, students were to print

The intent of thisstandard is to encourage businesses to minimize pollution during each step of a product’s lifecycle and plan for its reuse, in other words, from “cradle to cradle.”1,2,9Pedagogical FrameworkAn appropriate educational goal should be to make our students knowledgeable and sensitive tothe importance of environmental stewardship through the engineering and technologyassignments they are given. In order to achieve this goal the initial task must be to identify thedesired student learning objectives and then either find or develop appropriate modules thataddress them. Since ISO 14000 typically involves a variety of stakeholders throughout thecompany as well as the community, it provides an opportunity for meaningful

Once theseexperiments are introduced, we plan to collect student feed back and modify the experimentsaccordingly. The simplicity of the processing methodology presents an easy avenue for theintroduction into the undergraduate curriculum without any significant additional cost. Thevariation in the properties that is influenced by the processing methodologies presents anexcellent opportunity to educate the students on the process-property interactions and cross-dependencies in the material science and
, most students learnsome valuable lessons that can be applied in their other courses, such as varying reliability ofinformation available on the internet and cause-effect relationships (e.g., hardened 1040 steel isexpected to have an RC of 50, but an RC of 50 doesn’t necessarily mean it’s hardened 1040 steel).Summary and Future PlansFuture plans for the failure analysis project include group discussions of individual projects andpeer evaluation of presentations. Once lab facilities are upgraded to include projectors andmicroscope-mounted digital cameras, students will be able to present their materials to the classdirectly. This will allow discussion of various fracture surfaces and microstructures during lab.Additionally, students will

Formative assessment activities, including instructorfeedback, typically occupied at least one-half to two-thirds of each class period, with theremainder typically spent on “mini-lectures.” Students were asked to prepare for class by readingthe textbook and lecture notes and then taking a “preparation assessment” via BlackboardTM. Theopen-ended questions in these assessments were intended to reveal student misconceptions at aformative stage in the learning process. Fifty-minute class periods were then planned to bringthese misconceptions to the forefront. A feedback/voting technology called ClassroomPerformance SystemTM (CPS) was used to pose questions and problems to students and providethem with immediate feedback on

True or False?” This suggests that giving students the plots by themselves does notnecessarily transfer to an overall understanding of the mechanical properties. While this is notparticularly surprising, it is important to keep in mind when planning instruction, test questions,and so on for a course.Conclusion and Summary of FindingsWe reported here on student difficulties in understanding the mechanical properties of metals andon pilot instructional materials designed to help students overcome these difficulties. While weare not the first researchers to report students’ difficulties in understanding mechanical properties,our research adds to the exisitng literature on students

If there is something that is very complex then iy can be stretched another minute or two, but generally no longer than five minutes total. Our team is now working on expanding a database of brief videos that we can all pull from to clarify the ‘Muddiest Points’. These can be made right in the classroom with a student or teachers assistant as the lecturing person giving a PowerPoint explanation. If the video is focused and on point then this method is very effective. Another tool that the team is planning on incorporating into their JTF project is a Pencast.

However, the prerequisitecourse, Aerospace Structures I, is a required course for aerospace engineering degree studentsand provided to a fairly large number of students each semester (between 40 and 75 or so), andthe concept inventory exam might be used here each semester, to better modify and otherwisefine-tune it as an assessment tool.Availability of concept inventory examThe authors are happy to provide any educator with the latest

Approaches to Materials Science learning Materials science and engineering has grown considerably from its roots in experimentalmetallurgy and, recently, the main research breakthroughs have been driven by advances incomputational methods32. Thornton and Asta32 recently conducted a comprehensive survey about the state ofcomputational Materials Science in undergraduate and graduate courses at the 20 leadingprograms in the United States. While many universities are creating or planning to createComputational Materials Science courses, one striking conclusion from their work is that theprevailing mindset in most of those institutions is that one should learn modeling after learningthe science. In other words, computer modeling is regarded

He would be foolish to shave his head in hopes of a raise; the oldestengineers are paid the most, and are more likely to be bald.Students who write lengthy responses may tend to be smarter, harder working, more thoughtful,more literate; or perhaps they are simply better at planning their time. These characteristics leadto higher grades.Do Prerequisites Matter?A third indicator of success in 100Strength of Materials is the grade 80earned in the prerequisite class, StrengthStatics.

This courseplays the critical role of keeping students engaged in engineering while giving them experiencesthat have been shown to promote retention (see discussion below under “Utilization of BestPractices”).Each year of the curriculum has themes that we plan to emphasize. These are shown in Figure 2.In the first two years, we emphasize engineering basics and systems thinking. Two courses inthe sophomore year have been added to promote these themes and two existing laboratories wereadjusted. The two sophomore-level courses are Materials Selection for the Life Cycle, andNanotechnology, Biology, Ethics and Society. Both courses emphasize systems thinking, thefirst in the design process, the second through articulating

A challenge to educators isto increase the relevance of engineering core courses without spending an enormous amount oftime planning changes to enhance student engagement. As educators, we are aware of topics inthe core courses that are difficult for our students to learn, yet necessary for their development asengineers. Teaching styles that work with millennial students involve an instructor acting asfacilitator of learning. Providing directed active engagement within the educational environmentfrom the start of their experience will greatly assist the learning process of these students.The modules described in this paper were created to
the other integrated modules as a whole were collected, but not considered for thispaper. Because this module was developed while the class was being taught, certain logisticalissues could be avoided on subsequent iterations. For example, the placement of this module inthe course schedule could be more strategic. The low in-class attendance could be a result ofstudents attending conferences, the class occurring directly after an exam, and students beingaware that their instructor’s planned absence. Lastly, integration of feedback about theaccessibility case studies was elicited from professionals with expertise with the disabilitycommunity but not enough time was given to incorporate that feedback before the class wastaught. Future iterations
to understand the evolution ofstudents’ motivation. Most notably, the author plans to conduct a longitudinal study that repeatsthe survey for Study 2 at the conclusion of the Winter 2019 term so that the same cohort of studentsis evaluated at two times relative to the term. Additionally, the repeated study will allow for acloser comparison between the two groups of students (those enrolled during the Winter 2018 andWinter 2019 terms), to see if the student responses are still different at the same point in time.Alternatively, more qualitative information can be collected through short answer questions andfocus groups to elucidate students’ thought processes with regards to CMSE assignments. AsCMSE topics are added to the undergraduate
additional MatSEclasses into the SIIP program. In addition, we also have in place a mechanism for continuous re-vision and improvement of the existing computational modules through an end-of-year debriefand planning session, in which the SIIP faculty and teaching assistant conduct a “post mortem”of the computational modules. By identifying aspects of the material, delivery, and student re-sponses that were positive and successful, and those that were less so, the team identifies how andwhere to improve the material and its dissemination for the following year.The student surveys provide valuable information, but their utility as an assessment instrumentcan benefit from further improvement.

In 2017, student teams created bricks that depicted a scene, image ormemory of the University of Minnesota. The final change to Materials Processingthat occurred during the integration of CADand 3DP into the curriculum was the addition of lectures on the major additive manufacturingprocesses. Powder bed processes such as Selective Laser Melting (SLM) were discussed in thesame section of the course as traditional powder processing methods like compaction andsintering, for example. Since

The freshmen have only beenexposed to one module in MSE 182 rather than the two in MSE 201, which had previously beenthe first course with integrated computational tools in the MSE curriculum. We conclude thatexposure to the computational modules is fulfilling students’ desire for more computation in theirMSE classes, but that more modules are still desired. We are exploring whether modules can beadded to more MSE classes and plan to expand the number of modules in MSE 182 and MSE422, which currently only have one.6 ConclusionSince the survey of employers of MSE students by Thornton et. al. 1 , our department hasintegrated
