Recent Tutoring Session Reviews
"We covered reaction rates, rate law, rate order, activation energy, and the factors influencing reaction rates. The student's class started using reaction rate lab data in order to determine rate order. He was able to quickly learn the basics of working these types of problems. Both of them felt comfortable with the material overall both mathematically and conceptually. With a little more practice, they should be able to work the problems faster and not second guess what they are trying to solve for. They have a test on Thursday over this material, and I believe they will be well-prepared. I was informed that they are doing extremely well in their class."
"The student wanted to look at finding the equilibrium amounts of a reaction once it has reached equilibrium. We talked about setting it up. The best approach that I always suggest is to write down the initial amounts for both reactants and products, the change in x and the final amounts. The final amounts are calculated by using the equilibrium constant and plugging in the initial amounts +/- x. Once x is determined the final amounts can be shown. We practiced setting up and solving several of these problems. His only difficulty was that about half way through our session he was not subtracting the change from the original to find the final concentration. During our last couple minutes I asked him how he was doing with the trig functions and making changes appropriately for the equation when he needed to graph it. He indicated that he felt comfortable with the topic information at that time."
"Conducted a review of types of reactions and activation energy factors. Explained more in depth about how a catalyst works within a reaction. Completed practice with chemical equations going from words to formulas and equations. In addition, we completed strategies and steps for understanding diatomic molecules, correct balancing techniques, and formula development with charge assessments."
"Today we went through his acids and bases worksheet. I gave him an outline of how the different formulas for acids and bases work together, and showed him how to bridge from hydrogen concentration to pH. He did well, and was very thorough in writing down his solutions so that he could use it to study from in the future. We also previewed the topic he is starting next (titration) so that he is a little bit ahead."
"Today we reviewed epidemiological concepts related to biological interaction (additive effect modification) and survival analysis. We talked about how to properly interpret and present hazard ratios and the log-rank test. We will also review concepts to prepare for the final exam. I will send practice problems to help reinforce topics that the student may be struggling with."
"We covered Newton's 2nd and 3rd laws and how they apply to systems undergoing acceleration and not undergoing acceleration, with and without friction. The student told me that he understands the concepts but needs help explaining his work."
