On Being a Student
①What distinguishes a student? What makes the student stand out from the rest of the class? The four As : attitude, academic skills, awareness, and accomplishment, certainly are a large part of it, and a student who has them will be very likely to earn As.
②Attitude is primarily a genuine desire to learn, and the willingness to do hard intellectual work to achieve understanding. It is also shown by .how well you apply yourself even to subjects in which you have little interest,and how much you can achieve even when a professor' s style isn't to your liking.
③Academic skills include ability to read with comprehension, intelligent use of resources(including library resources), logical and mathematical skills, efficient study habits, and the ability to communicate clearly and fluently in speaking and writing.
④Awareness of what' s going on in the world around you, and the habit of intelligently relating it to your academic courses. For example, when taking a course in political science, you should relate what you are learning in class to what' s happening on the national and world political scene.When taking a science course, you should relate scientific principles to phenomena you observe in everyday life, and go out of your way to find applications and examples of science in the real world.
⑤Accomplishment is demonstrated by successful application of understanding. The evidence of that is : correct and confident application of what you've learned to new problems and challenges,clear and effective communication of your understanding through speaking and writing, and possession of a base of information, skills and understanding sufficient to allow you to continue your education outside of the classroom, throughout your life.
