the impact of gender for eachrace/ethnicity group? What is the impact of race/ethnicity for each gender group? This analysisexamines four main concept areas which measure student perceptions of their experiences,abilities and likelihood of leaving engineering: professor-student interactions, student-studentinteractions, self-confidence and risk of attrition.These questions are increasingly relevant as a result of expected demographic shifts in the USpopulation. The US Census Bureau projects that by 2050 all ethnic minority groups willcomprise 54 percent of the United States population.1 This will be a major shift from 2008 whenminorities made up one-third of the US population. Another demographic shift is related to thepercentage of women

be less effective forstudent learning. As Kenneth Kiewra of the University of Nebraska Lincoln has noted,“notetaking during lectures is occasionally no more effective than not recording notes . . .because of the often incomplete notetaking styles of college students”1 A better procedure,Kiewra suggests, is to “supply learners with a set of notes prepared by the instructor, rather thanhave them [students] record and review personal lecture notes. Under such conditions, studentswould not have to divide their attention during acquisition between listening and notetaking andcould subsequently review a far more complete set of notes than they would review typically.”1

Asnoted at the Summit on Women in Engineering 1, “we simply need people with the best mindsand skills, and many of those are women.” Furthermore, the literature suggests that a moreinclusive workforce is more innovative and more productive 2-4. In academia, the educationalbenefits of diversity are significant 5. Students with the most classroom experience withdiversity are more engaged in learning and self-report more gains in critical thinking, problemsolving and self-confidence 5.

How do we create that “sense of community” for commuter students as we have done so well with traditional on-campus students? 3. What type of learning environment would best benefit an urban

Thoughtstudents seem to be very interested in this topic, teaching public-key cryptography is somewhatchallenging since understanding the theory requires a high level of mathematical knowledge andskills.

At the same time, the authors note that “most people have very few direct, hands-onconnections to technology, except as finished consumer goods” and that this “lack ofengagement” is responsible, at least in part, for societal shortfalls in technological proficiency.Overwhelming evidence exists that students from all backgrounds have the capacity to becometechnologically literate, and that children of all ages can and do engage in complex reasoningabout the world 2, 3.

The representation and manipulation of knowledge is different in each of these channels. 2. Each channel has limited capacity. Each of these distinct channels has limited capacity to manipulate and retain knowledge. Too many spoken words and other sounds at any one time can overload the auditory channel. Too many images presented together can overload the visual channel. 3. Active processing provides learning. People learn when they actively process information presented on either channel.

Research SummaryNanorods have been widely investigated, and one significant application is in medicaldiagnostics4. Aspect ratio for a nanorod is defined as the length of the “fiber” divided by itsdiameter. It is believed that higher aspect ratio in the nanorod will contribute to theireffectiveness in protein separations when the nanorods are combined in a composite withhydrogels and then the composite is used in electrophoresis5. Electrophoresis is the movementof charged molecules (proteins) through the hydrogel driven by electrical current. In addition,balance of properties for the hydrogel composite is important, and nanorods
