will describe the development of an outreach activity for middle and high schoolstudents by Graduate Trainees, including initial approaches and revisions based on anecdotalobservations made from previously conducted workshops. Reflections from the Trainees willalso be included in an effort to understand how doctoral students with technical backgroundsdevelop pedagogically-sound materials that translate their research to new educational audiences.The primary goal of the developed workshop is to create an awareness of carbon nanotubes(CNTs) amongst participants and how their use in future applications within the field ofnanotechnology can benefit our society. The workshop provides a guided discussion viaPowerPoint presentation and hands-on

environmentfor students to study materials technology using the guided inquiry. The survey results in Q5-Q10 generally indicate positive perceptions of the active learning environment implemented bythe POGIL approaches, although there were the disagreements (1% to 3.8%) and neutralresponses (8% to 17.3%).Questions 6, 7, and 9 reflect the effectiveness of learning modules in class activities. Studentsfelt they already had a strong interest in learning course materials by the learning modules. InQuestion 6, a total of 93% of the students agreed and only 1% disagreed that the new POGILlearning modules helped them to improve conceptual development and enhance skills in study.The most neutral (17.3%) response was associated with Question 7 about how the

The groupdescriptions of renewable energy sources/energy related issues varied slightly, but some ofthe major corrosion problems are briefly summarized below.Solar Corrosive effects on solar panels Degradation of metallic reflective coatings and/or reflective substrate materials Corrosion associated with the metal connectorsWind Atmospheric, uniform and crevice corrosion of wind turbine blades Degradation of zinc or zinc/aluminum alloy coatings for corrosion protection Corrosion from extreme marine environments in offshore wind farmsBiofuels Stress corrosion cracking in pipelines

that instructors shouldpromote and facilitate student reflection so they become more metacognitive learners who candevelop their own expertise by defining learning goals and monitoring their own progress. Infocusing on the first principle, awareness of prior knowledge, it is critical to have an approach toreveal students' prior knowledge and understanding of a given topic in order to developimproved strategies for teaching that topic. In introductory materials science and engineeringcourses, one of the key topics to understanding the basis for the properties of materials is thetopic of crystal structures. An important aspect of instruction on crystal structures is for studentsto develop an ability to visualize two-dimensional projections of

. Figure 5: Aluminum Clamps with ABS Plastic iPod Holders mounted on an aluminum specimenExperimental Results and DiscussionIn measurements reported below, we kept the distance LG between the two clamps to beapproximately 4½” to achieve comparable precision in G measurements by both inclinometersand iPods. Figure 6 shows a plot of shear stress versus shear strain data points in the elastic rangewith least-square line fits to determine the shear modulus of 2024-T351 aluminum alloyspecimens. Since the inclinometer display changes by as much as 0.15 often, the horizontalerror bars for inclinometer data reflect this 0.15 uncertainty whereas the iPod data error barsreflect the Clinometer display resolution of 0.1.

(both design firms and ready-mixed concrete producers), more time to allow for a fieldplacement of the student project mixtures, and a student reflection session. The authors plan to pursue greater industry collaboration in future offerings of the course.The industry collaboration will be even more important in reviewing the technical report and oralpresentations as well as the potential for a field placement. The value in having industryinvolved in reviewing the technical reports and oral presentations is the feedback they canprovide. Individuals involved in the concrete industry can suggest modifications to the studentsin addition to commenting whether their design is “practical” would have the potential for beingused in the field
