Dictionaries define hurdling as jumping over a hurdle in a race. Obviously, Webster never made the track team. “A good hurdler never jumps,” the experts tell us. ‘‘He tries to duplicate the movements of sprinting. The head stays level. It’s never higher over the hurdle than it is between them.” A level head helps overcome any obstacle. Take bearing problems. They’re best approached by a person with training, determination and the ability to think things through. Are you such a person? When you run up against a tough problem, are you able to take it in stride? And do you like the excitement of rugged competition, and the rewards that come from winning?

Does one attempt to teach decision-making, require students to memorize basic principles and facts, instill in the students a method of thinking or attacking a problem, or teach design? These are difficult decisions, but ones that must be made. Equally important, however, is the manner in which the material is presented. This can be seen from the fact that most students either like or dislike a course mostly on the basis of the performance of their instructor. Some instructors, professors, and TA’s, are not concerned with this. Unfortunately this hurts our College of Engineering because we believe that there is a direct correlation between liking a course and learning the material presented in that course. Our College of Engineering, which is fortunate to have on its staff many exceptional engineering minds and leaders in their fields, is among the best in the country.
