Recent Tutoring Session Reviews
"Today the student and I focused on reviewing for her upcoming test. We especially focused on mole-to-mole ratios, writing chemical equations, unit conversions, and word problems. She is doing much better about catching her own mistakes as well as determining how to go about solving a problem. She did struggle a little bit with following the units at first, but became much better as we went along. She is a very enthusiastic learner and I have no doubts she will be able to master this quite soon."
"For our first session, we worked on some pre-lab questions and a homework sheet. We discussed the concepts of intermolecular forces and thermochemistry. More specifically, the energy required to heat or cool a substance as well as the energy required for a state change. Student appeared to pick up the material quickly, and has a strong grasp on unit analysis and calculations. We worked on a strategy for approaching the thermochemistry problems, which entails making a diagram. He really liked this method and I believe it will help him greatly when approaching these types of problems."
"We covered most thermodynamics and a little bit of kinetics. She has her test next month and she said these are the areas that she wants help in. For thermo, we went a little bit into La Chatelier's Principles and the basic concept of enthalpy, entropy, and Gibbs. She understood everything for the most part. She had a practice test that she wanted to go over these types of problems. I made her work out most of the problems which she knew how to do. I think she gained a lot more confidence after we did that."
"Today the student and I worked on matrix addition, determinant, and exponential of matrices. She needs to work on linear algebra, so we will do that next session."
"Today we covered rotational motion. The examples included motion of binary stars, motion of a car on an incline, motion of a rollercoaster car in a loop. The strategy was always to evaluate the net force which is a sum of all forces acting on the object of interest that is rotating, and then equal that force to the mv^2/r where v is the velocity and r is the radius of rotation. Another interesting problem was a plane making a turn in a given horizontal radius. There is a difference in which force of lift acts compared to the normal force on an incline. The problems with the incline required us to position our point of view such that we are looking straight into the car as the car is driving toward us. Student is doing an excellent job staying ahead of the class. Student is fast in understanding, execution, and is systematic in his approach of evaluating the forces, and breaking them down into components."
"We reviewed significant figures and accuracy vs. precision. His goal is to work more quickly through the problems."
