In 1997, the F. W. Olin Foundation of New York established the Franklin W. Olin College of Engineering, Needham, MA, with the mission of creating an engineering school for the 21st century. Over the last five years, the college has transformed from an idea to a functioning entity that admitted its first freshman class in fall 2002. This paper describes the(More)
Helical ribbons with pitch angles of either 11 degrees or 54 degrees self-assemble in a wide variety of quaternary surfactant-phospholipid/fatty acid-sterol-water systems. By elastically deforming these helices, we examined their response to uniaxial forces. Under sufficient tension, a low pitch helix reversibly separates into a straight domain with a pitch(More)
Understanding personal learning goals and perceptions of engineering is critical in encouraging students’ interest in the field. This work defines engineering in terms of the students’ course-related learning outcomes (e.g., skills and knowledge) described in the latest version of the Accreditation Board of Engineering and Technology (ABET) Engineering(More)
The self-assembly of helical ribbons is examined in a variety of multicomponent enantiomerically pure systems that contain a bile salt or a nonionic detergent, a phosphatidylcholine or a fatty acid, and a steroid analog of cholesterol. In almost all systems, two different pitch types of helical ribbons are observed: high pitch, with a pitch angle of 54 +/-(More)
In this Work-in-Progress paper we examine students' situational motivation in introductory STEM courses through analysis of survey responses about students’ experiences in a required course at each of two large public institutions. The students in each course convey different perceptions of course relevance: learning-performance relevance and temporal(More)
