Recent Tutoring Session Reviews
"During this session we returned to concepts covered during the last session. We covered moles, molar mass and Avogadro's number, and any calculations involving this subjects during the first part of the session. During the rest of the session we covered percent composition and empirical formulas. I left him with some extra practice to reinforce the concepts covered and also suggested starting to make flashcards containing important information that needs to be memorized."
"We did a review of electro-chemistry basics including standard redox potentials. We went over a practice AP exam test paper, covering galvanic cells, and electrolysis. I provided the student with a few good reference sites especially oxidation number methodology."
"We went over her chapter 12 homework with acid-base reactions and titrations. The student was struggling the most with titrations, which is expected because she just started that topic."
"In preparation for the test scheduled for Monday, this session focused on acid-base chemistry. Emphasis was placed on strong acid/strong base, weak acid/strong base, and weak base/strong acid titrations, as well as equivalence points, half-titration points and buffer systems. True to form, the student took to the material very well."
"The focus of this session was regulation of gene expression within viruses and bacterial cells. Specifically, we worked on dissecting how operons (i.e. lac operon and trp operon) function within the cell along with how viruses switch between lysogenic and lytic phases. Before our session, the student required extra focus with understanding what an operon was and what it did for the cell, but it made much more sense to him once we put it in the context of what cells need under certain environmental contexts (e.g. low glucose and high lactose; too much tryptophan). One of the student's strengths is that he is able to identify specific issues he is having problems with, which means I am able to better address his misunderstandings. Not only that, but he is always eager to overcome the challenges of understanding new material. This is always a plus when working with students. Although I did not leave him extra practice, he will be going over the material on his own again to solidify his understanding."
"We focused on understanding NMR and synthesis problems. We worked on understanding how to use the reactions learned throughout the semester in order to solve synthesis problems. We also worked on understanding how to use NMR along with other techniques to solve NMR problems."
