The challenge in engineering education is to take advantage of the positiveeffects and understand and deal with the negative effects.The authors have been actively using technology to enhance engineering education and haveobserved that students often develop an expectation that learning should be easy and primarilythe responsibility of the teacher. Students, however, that make use of the new teaching tools (on-line lecture notes, simulation and modeling programs, etc.) achieve greater academic successthan would otherwise have been attainable. It is clear that students who achieve academicsuccess are the students who really learned. But who are the students that are learning in thisnew technically advanced learning environment?
