Assignment 0 Friday, August 30, 2013 In your mathematical careers, it will be increasingly more important for you to demonstrate good problem solving skills. The emphasis is shifting from being able to grind out rote calculations like you did in Algebra and Calculus, to being able to solve original problems. And part of problem solving is being able to explain to others how you solved the problem. For that reason, your homework will be graded on how much work you show, and how much you explain your reasoning. The following is a sample problem along with several different possible student responses. Each response is graded, and the grade for each is explained. 1. Find the distance between the points ( - 1 , 3) and (2 , - 1). Solution 1 : 16 Grade : 0 out of 5 points Explanation : The answer is incorrect, and no work is shown. Solution 2 : 5 Grade : 1 out of 5 points Explanation : Although the answer is correct, there is no indication by the student how he or she obtained the answer.
