Optimizing Engineering Materials Laboratory Time with TechnologyBySteven M. Cramer, Nancy Ciezki, Hussain Bahia, Carole Kraakand Carole SchrammUniversity of Wisconsin-MadisonAbstractThe background of engineering students has changed over the years, resulting in newchallenges in teaching hands-on laboratories. Engineering design involves visualization.This visualization spans the spectrum from understanding how pieces of a structure fittogether to having a first hand knowledge of how material deforms, flows or fracturesunder different loads. Engineering laboratories provide critical hands-on experiencesthat build visualization skills at the same time that material or structure behaviors aredemonstrated. But engineering laboratory time is

The background of theearly engineering students in materials science was grossly inadequate. Therefore, they wereprovided some basics on materials in the lecture classes.

. Science, technology, engineering and mathematics (STEM) education in America is not yetachieving satisfactory results with traditionally underrepresented minority students. The high attrition rateof African Americans from the STEM pipeline has been identified as a greater barrier to increasedrepresentation than their attraction to non-quantitative fields. Critical thinking skills and self-directedinquiry are two areas that if enhanced at the entry level of science and engineering education, couldpossibly increase motivation for STEM careers for minority students when other barriers are addressed.There is a need within the curriculum for a process focused on how to effectively deliver the fundamentalidea of the material to help the students learn
