“…Engineers and educators of engineers have been challenged to adhere to these goals in the 21st century (Duffell, 1997;Hill, 2000;Henry, 2002;Miller, 2002;Steinemann, 2003). Engineering educators have recognized that engineers must become more aware of their impacts in terms of global development and sustainability (Crofton, 2000;Carratto and Haryoff, 2003;Steinemann, 2003;Holtzapple and Reece, 2005). At the same time, engineers must also face constraints or limitations imposed by budget, time, personnel, material properties and availability, and manufacturability (Miller, 2002;Holtzapple and Reece, 2005).…”
