Recent Tutoring Session Reviews
"In this session, we continued with chemical equilibria. We went over several problems that involved changes between initial conditions and equilibrium. The student was learning Le Chatelier's principle, so we went over several practice problems to explore this concept and its implications. At the end of the session, he also asked for some help with his calculus homework, so we went over applications of derivatives."
"The student and I first discussed the pre calculus homework from last week, which covered exponential and logarithmic functions, their graphs, and solutions to their equations. The student has a very good handle on exponential graphs and their basic vertical and horizontal transformations. The most challenging part was solving logarithmic equations by rewriting them as exponential ones, and then using basic properties of exponents. We reviewed the basic exponential properties for division, multiplication, and multiple exponentiation. We spent the rest of the session reviewing for his upcoming AP chemistry test this week. We went over galvanic cells and how to determine the cathode, anode, and direction of the equation. The student has improved in his ability to analyze redox reactions. He received a B on his math test last week."
"In this session, we continued to work on the diagnostic test and cover topics that the student is also learning in class. She had a specific question about the difference between bond polarity and molecular polarity. This continued into a conversation about molecular orbitals and hybridization. She notified me that she received a 98 on a dot structure assignment and an 80 on her last exam. I did not leave her with any extra practice after this session."
"We went over online practice problems that involved ph and acid base chemistry. Specifically we went over conjugate acid/base pairs, how to recognize them, and how to use this information for chemical equations. The student showed progress in her approach to many of the problems and applied many of the concepts discussed in previous tutoring sessions. Overall, great session and progress."
"For today's session we worked through the students' latest assignment concerning various topics within the realm of stoichiometry. We worked through problems of percent yield, balancing equations, and limiting reactants. Both students already seem to have a good grasp of the concepts and material and I only had to give some procedural guidance for solving some of the more complex multi-step problems."
"The student and I spent the majority of our session covering redox reactions. We wrote out rules and applied them to a few homework problems. We also briefly touched upon the major gas laws before our time was up."
"Today we worked through his homework problems on thermochemistry. Overall, he was very strong in his understanding of the concept, but he initially made mistakes when it came to signs and conversion between joules and kilojoules, so as the session progressed we became more careful of those. Probably his only issue was being unsure of the iterations of Hess's law, because when it came to summing reactions to get a final reaction coordinate, he was instead looking for "products" and "reactants" versus the net equation. I stressed that they were ultimately the same equation boiled down, but not to be used interchangeably (because they can't be!). I left him with the rest of his review sheet."
"Today we looked at the student's past tests, upcoming homework and lab reports. We covered dimensional analysis, molecular shapes, intermolecular attraction, hybrid bonding, and topics relating to acid-base neutralization, among other things."
"We conducted practice problems and classwork of determining the number of moles, grams, atoms and molecules of compounds. We utilized conversion factors, Avogadro's number and molar mass to achieve these values. In addition, there were some questions on wording and introductions to new concepts that were outside of the scope of the material. I plan to introduce acid nomenclature to the increase depth on knowledge of the material at our next session."
"We went over gas stoichiometry - how to calculate grams from liters and the mass of the reactants from a given volume. Additionally, we worked on the rate of diffusion and effusion - understanding how to use the formula and how to find both the rate and the mass from Graham's Law. She understands the material, but just needs help working through them. She has another assignment due this week that she will work on tonight and then we will review tomorrow. UPDATE: She received a 'B' on her last exam, so I am very proud of her growth!"
"We worked on her homework assignment. As we got to a question we discussed the concept to make sure she understood why she chose the answer. She seems to understand basic concepts, periodic trends, electromagnetic spectrum, things like that. I think she needs more help with the math side, including units, conversions, SI unit prefixes. We didn't get through the entire assignment, so I asked her to continue to work on it, and next Monday we will look at what's left and answer any questions that come up."
"The student and I reviewed thermochemistry again. It was the same topic we briefly covered last week. She handles the material well and has a good understanding of the concepts. She has no trouble with the mathematics."
