They enter intolearning more purposefully and with greater motivation. Knowles’ popularized a four-stepprocess for SDL: 1. Diagnose & formulate learning needs 2. Identify resources for learning 3.

Joseph Lowman in Mastering the Techniques of Teaching, statesthat “college classrooms are fundamentally dramatic arenas in which the teacher is the focalpoint, like the actor or orator on stage” 2. What better way to break the monotony of informationtransfer than a good story. Papadimitriou has recognized three main ways of using storytelling inthe teaching of a technical subject: (a) providing historical/biographical context to a subject, (b)illustrating a concept by a story, and (c) embedding educational material into a story 3. Thispaper provides examples of storytelling in a Materials Science class and student reactions to theclass. The paper is intended to serve as the starting point of an audience discussion during thepresentation

In restructuring the course, I decided toadd comparable emphasis on structure and processing of materials as it relates to testing andcharacterization of metallic materials.This paper describes the first three of the seven experiments that were developed focusing on: (1)Introductory Image Analysis and Brinell hardness testing, (2) Strengthening mechanisms and tensiletesting, and (3) Cold working and Rockwell hardness testing.

In fall of 2015, this wasconverted to an applied lab to better meet ABET Engineering Technology AccreditationCommission Student Outcome 3a [1]. The lab was modified to include input for anisotropicproperties. Coincidently, Zhang at the 2015 ASEE Annual Conference in a conference papertitled “Understanding Additive Manufacturing Part Performance Through Modeling andLaboratory Experiments.” [2] suggested having an applied lab for anisotropic
taught various models as explained below.Types of models: Structural models can be defined in a variety of ways. When building amodel, the most important question one should ask is, “What do I want from this model?”. DoI want to know when this model is going to fail? Do I want to demonstrate a behavior? Or is itsomething else? Based on the requirements, it is decided what type of models should be built.Some popular models are described below [1]: • Elastic Model: An elastic model usually is geometrically like the original but may be made of a different elastic material. This is a good model to study the elastic behavior but is not useful is predicting the plastic behavior. This model is usually built with plastics such as

Colleges anduniversities abruptly stopped in-person instruction and instead required remote teaching.Instructors’ challenges included preparing virtual lessons, learning videoconferencing software,and selecting appropriate graded assessments. At the same time, students’ learning routines weredisrupted as many returned home and were away from their peers; some students also lost thesafety net that the university provided, such as reliable food and shelter [1]. Furthermore, bothstudents and faculty were affected by limited internet connectivity and additional familyresponsibilities due to the

However,students benefit from intentional interactions with professionals in their area of study [1].Informational interviews, site visits [2], industry-sponsored projects [3], and adjunct instructorsfrom industry [4] all provide educational advantages within the context of an engineeringcurriculum. Each of these can require a great deal of time on the part of the industry liaison ornecessitate curricular changes. Another common tactic is to bring in a guest lecturer for a singleclass session to give a talk on her specialty or to tie class material to industry. This is a fairlycommon practice and relatively easy to schedule because one

The broader region includes two steel minimills, severalwire mills, automotive parts manufacturers, a pickup truck assembly plant, recreational vehiclemanufacturers, orthopedic implant manufacturers, defense plants, and many medical toolmanufacturers. In 2015, the university's chancellor heard from regional business leaders that theyneeded more employees with a knowledge of materials. This demand is supported byemployment data from the Bureau of Labor Statistics, which defines the “location quotient” ofan occupation as its share of local employment relative to that occupation's share of nationalemployment. The location quotient for materials engineers in Indiana is 1.49, or 49% higher thanthe national average. [2] Similarly
change at the atomic and molecular level.It is a central process in materials science and engineering (MatSE) as well as in chemistry,chemical engineering, molecular biology, and any other science dealing with atomic scalephenomena. Therefore, all students of atomic-scale sciences ideally should acquire a deepunderstanding of diffusion, but such understanding has proven difficult to achieve across age-groups and subjects [1]–[5]. One core reason for the difficulty is that it is not obvious how themacro-scale behavior—net movement of particles from regions of high concentration to regionsof low concentration—emerges from random-walk behavior at the submicro-scale. This leads to“levels-slippage” [6] in which a person assumes the behavior at the

All of the full documents are included at the end as appendices.Initial Exposure to Technical WritingJust before students begin working on their first lab report, I assign them a technical journalarticle to read [1] and a set of questions about the article to answer. The article is short (3.5pages including many graphs) and related to a topic that we are currently covering in lecture(solid state diffusion). The article I use was found with help from my university’s engineeringlibrarian. The students must answer questions related to both the content of the article (e.g. Whatis the diffusivity of copper when the carbon content is 0.6% and the

In recognition of this, considerations of social and environment context and factors arespecifically stated in ABET student outcomes 2 and 4 [1].Sustainability requires a balance between the competing interests of various stakeholders whichform a Triple Bottom Line [2]. These three aspects, sometimes called the ‘3 Ps’ are Economic(Profit), Environmental (Planet), and Social responsibility (People) [3] can be described as

Students will prepare case study reports, applying each ethical theory to the case.Students are then further asked to identify what could/should have been done differently. Studentsare encouraged to examine cases from all angles, as is common in ethical analysis.In Week 6, the students were given the creative writing assignment. This assignment is shown inFigure 1. This assignment was initially intimidating to students. However, all 18 students in theFall 2019 cohort scheduled a meeting with the faculty member in charge of the course within 1week of being given the assignment. There

The goal of the experiments is to help students determine howdifferences in concentrations of nano-sized particles, which are added to common materials, canchange physical properties. In this exercise, student teams will fabricate composite films filledwith different concentrations of carbon black in two different types of polymers: 1. latex-basedcomposite with poly (vinyl acetate), and 2. solution-based composite with poly(vinylpyrrolidone). The concentrations vary from about 2 wt% to 15 wt%. For mechanicalproperties, the students will determine the

Much of the content relies heavily on previous knowledge. This is wherethe students’ eportfolio or repository of information comes into its own. The basic resourcesneed for understanding the topics in second and third year MSE are grouped and available as anelectronic resource for all students to access. For example in the second and third year subjects,HES2281 and HES3281 topics associated with steels, polymers and ceramics experiments on
transition happens within a bounding temperature range.While standard tensile test as well as izod test on polymers are very useful and fundamental tomaterials testing, polymers behave in a unique fashion when pulled suddenly with an impactload, which mimics high strain rate. Impact testing explores an object's reaction to highdeformation rate or strain. An impact test is intended for determining the energy absorbed infracturing a test piece at high velocity/strain rate. There are 2 standard bending impact tests;Charpy and Izod. Figure 1 shows standard specimens for these tests. Figure 2 shows the level ofenergy absorbed by specimens of a particular material tested at different temperatures. STRIKE (a

The book project essentially evolved as a scholarly experiment designed to 1) addressopportunities and challenges faced over a decade of instructing students from diverse disciplines,and 2) create a cross-over instructional resource that emphasized the solid role of materialsscience in manufacturing for use chiefly by students of engineering studying manufacturingprocesses and materials science.
