Recent Tutoring Session Reviews
"Today student and I worked on Molarity and Molality problems. I was able to provide her with some quiz questions and exam questions specific to molarity, when a compound is weighed out and dissolved into a specific volume of solvent. I also reviewed % w/w, % w/v, and % v/v type problems and dilution problems. She seemed to show aptitude for Molarity problems and % concentration, but she stated that she would probably not be responsible for dilution problems on her next exam so we didn't cover these types of problems in great detail."
"Today, I met with student for the first time. We sat down and discussed his tutoring goals, and he mentioned that he has a test in the next 10 days for which he would like to prepare. He got a C on his last exam, so he's looking to improve his grade. When I arrived, he was working on problems about bonding principles. We continued with his assigned problems touching on topics including: Lewis structures, period trends in electronegativity, atomic size, and electron affinity, bond strength, extended octet, and resonance. Our next meeting is scheduled for tomorrow. We will continue with topics that will be tested in his upcoming quiz."
"We conducted practice with IUPAC system of nomenclature of compounds. I reviewed aspects of understanding the difference between ionic and covalent compounds to aid in the naming. Understanding aspects of the formulas and charges was also a focus in this short review exercise. I also completed some practice of stoichiometry and converting with moles, grams, and particles. In addition, we completed an overview of types of the 5 basic reactions to prepare for next session."
"We went through the student's review packet, covering topics on converting from moles to grams and vice versa using the molar mass, names of glassware and equipment in the lab, physical and chemical properties, elements vs compounds vs mixtures, models of the atoms, and electron configuration."
"Today the student and I reviewed some practice problems I gave her Wednesday. She did a great job setting up the problems correctly, and just had a little trouble with the math. She struggled mostly with generating chemical formulas, but we reviewed and she was doing much better by the end. For new content we reviewed naming of chemical compounds. She did a great job! She completed the exercise problems correctly, and I will give her some more practice problems for our session on Monday."
"During this session we focused on reviewing acid and base concepts for an upcoming quiz. The student seemed comfortable with nomenclature and writing reaction equations, so we did not spend much time on these concepts. We reviewed how to calculate pH, pOH, [H+], and [OH-] for strong acids and bases. He was a bit slow with these calculations at first, but gained confidence with practice. We also reviewed how to solve neutralization problems. He seemed to grasp the concepts as we walked through an example problem, but I advised him to do more problems on his own to prepare for the quiz. We also discussed how to calculate pH with weak acids and bases using equilibrium constants. He seemed confident with the ICE tables, but struggled a bit with the math involved in the equilibrium expression and quadratic equation. He was able to successfully complete a practice problem, but I advised him to once again practice this strategy more before his upcoming quiz."
