Recent Tutoring Session Reviews
"I began by having the student tell me how he felt he was understanding the material for the chapter. For the most part, the math involved in calculating isotopes and atomic weight from isotopic abundance were quite easy, and the theory simple. We spent the time going over review questions from the back of the chapter, including delving into cations and anions, which the class had not covered yet. We spent time going over how and why certain elements "want" to have certain charges, which segued nicely into ionic bonding and ionic compounds. The student also wanted more clarification on the various types of chemical formulae, such as empirical vs structural. We touched briefly on alpha radiation and atomic radius (as they related to Rutherford's Gold Sheet), and a small bit on Lewis Dot structures and electron notation. We agreed to review the remainder of chapter 2 and if possible forge ahead into chapter 3 next time."
"The student and I worked on her organic Chemistry as per her request this session, taking a break from our MCAT work. We went over resonance, something the student had some trouble with on her recent quiz. She was a bit confused about the possibility of carbon taking on a negative/positive charge, but after going over this together she got the hang of this. We spent about an hour going over this concept because it can be a challenging one to understand and internalize so we did a number of practice problems to expose her to the many options that could be tested on her midterm. We then went over her class notes and some confusion she had over the application of thermodynamics to Newman projections as well as the Schrodinger equation in relation to probability distribution of electrons in orbital levels. We discussed why her teacher went over this and the depth of knowledge she will likely need for her exam. We will go over her quiz the next session, develop a schedule for her MCAT studies, and continue with either organic chemistry work or MCAT content."
"We covered a chapter of the textbook which covered resonance structures, hybridization of atomic orbitals, molecular orbital theory, valence bond theory, isomerism and basic nomenclature of alkanes."
"Today, we covered electric values. Specifically, the student was confused by all the different values introduced in class, and wanted help distinguishing them. Toward that end, I gave a short lecture culminating in a four-square view of electric force, electric work, electric field, and the voltage, which helped to cement the relationships between these values. She we began working her homework. She seemed to already know what to do, and just followed along this time showing more knowledge. The only trick she missed the first time was for the electric flux, that the angle between a perpendicular to the surface and the electric field is used. By just practicing a couple of times, she will have that down pat."
"Today's lesson consisted of review of material as pertaining to the student's online chemistry class. Subject matter included acid and bases, how to determine pH, equilibrium, and related constants, how to construct ICE tables, and how to determine Ph of salts. All questions were answered and various examples were performed. The student was able to identify and apply concepts relating to the material discussed. She will continue to perform practice problems and read text to further reinforce her knowledge and understanding of the material."
"Always wonderful to work with the student. She comes so prepared and ready to work. Today we went over entropy and enthalpy and Gibbs free energy. We talked about using logic to answer questions as well as numbers, watching for her common mistakes (unit conversions!), and general test taking and organizational skills. Next meeting is Thursday at 4."
