"The student and I continued our discussion on the principles of torque after she had gone over these concepts in class. Now that she was assigned homework problems, we were able to get more practice with various problems surrounding torque and rotational equilibrium. There was little problem setting up the problems given in her assignment so we moved pretty quickly through them. I helped her set up her problems correctly, and we discussed the concepts behind what is going on in each situation and how that would affect torque. Then she did the calculations. After finishing the majority of the assignment, the student began inputting her answers into the online assignment but was continually getting the wrong answers. As we revisited each problem one by one, nearly 95% of the problems were set up the right way, but the calculations were done wrong. I suggested that she do the problems in an all-at-once fashion on the calculator so that she limits calculator error by rounding or doing each operation separately and then adding/subtracting or multiplying them. When she re-did the problems by inputting the variables all at once, she got the correct answers. I'm glad that she understands how to do the problems, which is most important, but I asked that she do some practice using the calculator. The student is really grasping the concepts of torque so I assigned her a difficult challenge problem at the end of the session and asked her to set it up without actually solving it. I reminded her to set up the problems based on her conceptual knowledge of torque and then work through it nonetheless because most times those missing variables will cancel out anyway or will not be needed at all. Next session we will move onward to rotational motion, and I will revisit translational motion."
