we share some of the quotes we heard from the students: “I am still very cognizant of my accent. I always fear that I make grammatical mistakes as I talk. Like very often I make the mistake of using a plural verb for a singular noun. It’s hard. It doesn’t come naturally to me. I know it might be a small mistake, but I have that in my mind all the time. When I talk, I constantly remind myself to check my verbs - did I use that little ‘s’ at the end of the verb or not?. I fear what if I don’t get it correct during the presentations. Are reviewers going to doubt my capabilities? I am more confident in front of my advisor or others who believe I know my work and I am good at it. But when it comes

While boys are socialized to continue in high school math, evenif they may dislike it, because they know it will be required for a jobthey know they will need, girls are socialized to consider math unfemi-nine, unnecessary and too difficult. Unfortunately they are often sup-ported in this attitude, not only by their peers, but also by theirparents, teachers and counselors.The organizers wish to encourage these girls to think about their fu-ture, not necessarily in terms of a specific occupation, but in termsof today s statistics (3): 1More than half the women in this country are in the workforce.Women work an average of 25 years.80% of working women are employed in

The objectives of such acourse are typically to increase the students understanding of what engineering is, provide somebackground knowledge and experiences that will serve as a foundation for the material they willlearn over the next 4 years, and to encourage the student s interested in the field of engineering.Typically the culmination of these classes takes the form of a design project. The format of thedesign projects can vary, and this paper will discuss two very different formats that the authorhas used thus far in the Introduction to Civil Engineering course at the University of MinnesotaDuluth (UMD).
