Recent Tutoring Session Reviews
"In our previous session, the student worked on molecular formulas, and calculating the yield of reactions in his Honors Chemistry class, and how to identify holes, asymptotes, and intercepts in rational functions. During our session we started out by going over the Pre-Calculus homework, dealing with factoring out rational expressions. With very little assistance, he was able to do several of the homework problems. We then switched to the Honors Chemistry homework, dealing limiting reagent problems, which I had taught him on Wednesday. He breezed through the problems, making a few basic errors, but improved over time. The concept that the student struggled most with was remembering the conversion ratio for mass to moles using the molar mass, the proportion with regards to mols is always 1. Sometimes he gets a bit excited and combines it with the proportion in the reaction, but he has gotten much better at avoiding the mistake, especially in this session. Although there were no new scores or grades to note progress, it was apparent from observing the student work that he had improved, able to notice trends and to how to best take advantage of that knowledge. I believe that he will do well in following class periods for both of the subjects."
"The student and I went over chemical equations, covering chapters 5 and 6 of his textbook. Specifically, we went over how to balance a formula unit equation, how to write complete ionic and net ionic equations and how to determine the oxidation states of each atom in the equations. We covered displacement reactions, metathesis reactions, redox reactions and acid-base reactions. The student understands how to balance equations well and I gave him a good strategy of how to approach more complicated-appearing equations. He struggled a bit with writing complete ionic and net ionic equations and determining oxidation states, so we focused on those topics towards the end of the session. The student has a chemical equations quiz coming up this Tuesday and is hoping this will boost him up to the grade he is shooting for. I encouraged him to continue the practice problems from the book and to email me with any questions he may have before his next quiz."
"We reviewed for her upcoming exam. We went over the addition reactions to alkenes and alkynes. We worked through two practice exams and I saw her develop a lot more confidence in her electron movement. I feel very strongly that she know the material very well but sometimes gets hung up on her hesitation. I encouraged her to practice drawing out the reactions that we went over. She felt a lot more confident about this exam than her previous ones and I look forward to seeing how she did. We discussed mass spectroscopy, infrared spectroscopy, and nuclear magnetic resonance. These are slightly different than the past material we have gone over and they described the physical measurements that allow us to determine the organic structures that we have been learning about. We worked through suggested problems out of the back of the book and developed strategic ways to interpret the numbers and the structures that make up the graphs in front of us. We additionally discussed radical reactions and I gave her a basic overview before her lecture on Wednesday. I again saw a lot more confidence in her arrow movements and consistently saw her face light up when she understood how to complete the problem with the correct answer. We plan to meet again this Thursday to discuss her exam and begin preparing for the final next Wednesday."
