Recent Tutoring Session Reviews
"Today the student and I looked at an especially long, difficult, and abstract problem set that he had just been assigned. The topic was electron configuration/orbitals. For such a complicated topic he learned remarkably quickly and was able to identify characteristics of s, p, d, and f orbitals by the end of the session. He also mastered finding wavelength, frequency, and energy of a photon. It went really well!"
"We reviewed chapter material for his upcoming test. We spent most of our time applying Hess's Law. The student found it challenging to choose the order of adding equations and also to manipulate them so that the correct compounds were on the reactant and product sides. He practiced strategies that involved isolating the compounds that only occurred in one of the given reactions and then multiplying the reaction by the appropriate constant in order to make the coefficients match. He also worked a few problems on standard enthalpy of formation using the standard enthalpies given in the appendix. The student said that he would review the problems that we discussed tonight. I wrote down several example problems for him to review."
"Today we reviewed some topics that will be on the student's test, such as enthalpy, entropy, and Gibbs free energy. She ran into a few challenging problems. Once we discussed the problem, it flowed nicely. She has a good grasp on the subjects and should do well on her test."
"The student had started covering thermodynamics. Her teacher had provided her with a practice packet with questions in multiple choice and free response formats; they were encouraged to work the former questions without a calculator. We reviewed the meanings and interpretations of enthalpy, entropy and Gibbs free energy, and worked through many problems that involved applying these concepts and calculating specific values. Although she had learned Hess' Law before and practiced it with me, she did not remember how it worked. Before long she was back up to speed and getting correct answers with little trouble."
"The student and I discussed topics that his class has not covered yet since he recently took the test and does not have the results back yet. We covered topics about general physics relevant to his future lessons in chemistry, such as wavelength, frequency, Coulomb's law, and electron orbital models and theories. We also briefly covered trig functions and the unit circle since those concepts will most likely be covered soon in his calculus class. We discussed differentiation and integration of trig functions. He picked up on most topics I discussed pretty quickly. In the next session we will review any mistakes he made on his test on electrochemistry and balancing redox reactions."
"We went over reaction energetics. We also covered topics including catalysts, rate laws, and how to determine the orders of reagents from a reaction rate experiment. We also covered rate-determining steps in multi-step reactions. We ended with a summary of the upcoming class material involving equilibrium and Le Chatelier's Principle. The student seemed to understand the material even better than usual."
"Today was our first meeting. We discussed his weaknesses and then the things he would like to work on prior to the exam in May. Today we went over the Gas Laws and how to calculate using them. We also touched briefly on the K value, which he appears to be getting."
"Today we went over the study guide for his upcoming test. The test will be on molarity, molality, percent composition, and changes in BP/FP. He understood the differences between molarity and molality and when to use each equation. He had a little difficulty with the mass percent equation because the mass of the solution was not the same as the mass of solvent. However, he eventually understood the difference between the two and was able to find the correct answers to those questions. He didn't struggle with any of the material."
"Today was our second session. The student and I worked on stoichiometry in chemistry. We learned how to figure out using moles, molecules, Avogadro's number, and mass. We learned how to find the limiting reagent and figure how the percent yield. We discussed the meaning of standard temperature and pressure. We first worked on her online notes, and then completed a worksheet. After that we completed an online quiz. The student is doing really well and learning quite a lot."
"Studied for chemistry exam. Went over practice problems involving light years, wavelength, and frequency. Also did organic chemistry problems involving creating isomers, naming compounds, and learning functional groups. Student is very well prepared for the exam and has been doing a lot of practice problems."
"The student and I went over how to read phase change graphs and understanding what enthalpy is. She got it very easily and how to find specific heat came easily to her as well. She was able to get all the answers to her homework easily and the extra worksheet she had she did easily with little help. She has improved greatly throughout the year and is a very good chemistry student."
"The student will be taking Chemistry II in the summer. Using the book as a guide for topics, I decided to give her an overview of the concepts she will learn. Today we reviewed basic concepts (periodic trends, etc.) and covered intermolecular forces, properties of gases, and the ideal gas law."
