Recent Tutoring Session Reviews
"We covered rotational motion, including rotational kinetics and dynamics. We also did problems on collisions (elastic and inelastic) in center of mass frame of reference as well as in a "regular" frame of reference."
"The student was working with concepts of torque and how to calculate it, and we broke the concepts down into the pieces that go into torque: a force, an offset "lever arm," and having some part of the force perpendicular to the offset."
"We did a brief overview of enthalpy and the different ways to calculate the enthalpy of reaction focusing mostly on Hess' law. The student was struggling a bit at first because she was trying to approach the problem inefficiently, but by the end of the session, she could do it easily. We also worked through a few multiple step stoichiometry problems and discussed how to best approach IB questions."
"In this session the student and I covered the chapter on Coulomb's Law in the review book. Several places he needed particular instruction on were trig identities, the small angle approximation, and complicated fraction algebra. As a physics concept, he understands Coulomb's law well, but he struggles with mathematical applications in the process of solving problems. We'll work on this in our next session."
"The student and I covered the review packet for the test. Looking at the past test, I could see that the teacher focuses more on the theory. For this particular unit, I do not think there will be difficult math problems that the student will not be able to solve. In fact, he is an intelligent student who can do well in math problems. Today, the difficult part was colloids. The review packet heavily focused on this particular topic. He said he will study that further. For this unit, the most important thing will be to memorize the material (theory mostly) in the review packet. The good thing is that most of the math equations are on the formula sheet he gets on the test. We will work on developing an efficient way for him to memorize materials."
"The student and I reviewed the concept of endothermic versus exothermic reactions, and how to calculate the enthalpy change of a reaction given a specific amount of reactant. We then learned about phase change along with distinguishing the difference between the determination of heat transfer from changing temperature versus heat transfer during a phase change. We did several practice problems, involving identifying the type of heat transfer, calculating the amount of heat transfer, checking unit consistency, and summing up each step to get the total amount of energy. We also discussed calorimetry and the transfer of heat between a system and its surrounding. Although this topic required more math, she was able to arrive at the correct answers. I plan to introduce entropy and Gibbs free energy in the next session and wrap up thermochemistry."
