Recent Tutoring Session Reviews
"For today's session with the student, I conducted an overall preview of their next unit, chemical equilibrium. I began by describing the law of mass action and equilibrium constant expression, the dynamism of chemical equilibria and how it relates to thermodynamic equilibrium. We discussed the difference between K and Q, the reaction quotient, and how to predict the direction a reaction will take place based on a momentary Q value compared to K. I described how to calculate a K value based on pressure for gaseous systems, as well as the relationship of K and Kp. I also focused on giving a clear definition of Le Chatelier's principle and how it applies to predicting the movement of reactions and shifting of equilibrium based on various stresses imposed on a system already at equilibrium. We concluded by answering several conceptual practice problems to solidify some understanding. We will have an assignment to work on more calculation based problems at our next session."
"The student and I covered the Fourier transform in its forms. We mainly focused on understanding the different forms and notation that needs to be used. The session went well."
"The student was working on problems of gas laws and thermodynamics, and I think that he had some good insights into how to set up the problems and some good questions about why we were doing certain things. We covered the ideal gas law, Boyles' law, Graham's law, and Dalton's law. He picked up the computations quite well once the problem was set up, and seemed to have a good handle on some of the material by the end."
"We went over several calculus- and vector-based energy conservation problems. We also worked on a few kinematic/force analysis lab problems. The student knows his stuff pretty well. He is largely self-taught, so he just needed some informed explanations of some concepts to fill in gaps and help to tie ideas together."
"We went over solubility compounds, Hess' Law, equilibrium equations, and some calculations. The student is struggling in problem-solving, but he has a great attitude toward the material that was reviewed. Some calculation strategies were taught as well."
"We went over some basic properties of circuits. We started with a bunch of problems where we straightforwardly applied V=IR, and talked about the units on all of the relevant quantities. We spent most of the lesson focusing on how to treat resistors in series and in parallel: finding both the equivalent resistance and discussing how current is split in parallel paths. We noted that each resistor in a series will cause a voltage drop, and that the entire current will cross each resistor. In contrast, when resistors are in parallel, we will see the same drop in voltage across each resistor, but the current will divide itself among the paths according to their equivalent resistance."
