concludes. Thisnot only erodes the integrity of evaluation within an academic program, but also has seriousconsequences for the team as well: experience shows that simply having to cope with a non-performing team member can actually result in more stress and effort for the team than if thatteam member were not present at all. Ultimately, nothing erodes team morale faster thanworking overtime to make up for a poorly performing teammate, only to receive exactly thesame evaluation. Thus, development of reliable mechanisms for (a) quickly detecting anddealing with internal team problems, and (b) adjusting individual credit given for team productsbased on actual effort invested by each individual is crucial in any team project context

College credits have three utilities: (a)enhances the student’s college application, (b) makes college education more affordable, and (c) reducesthe course load in the initial year and allows the student to settle into college at a convenient pace.5,6 Atpresent there are a large number of introductory engineering programs, however, rarely are theseprograms ABET accredited and provide transferable college credits to high school students.
