Recent Tutoring Session Reviews
"In this session, we covered topics on Lewis dot structures from a worksheet that her teacher provided in class."
"The student was concerned about a lower than expected grade on her recent test - she mentioned that she had problems with the stoichiometry of redox reactions. Unfortunately, she didn't have the test back yet, so I told her we would go over it during the next session. During this session, we mostly talked about gas laws. We worked through many problems using the Ideal Gas Law and other gas law equations. The student did very well on these problems and seems to have a good grasp on the method for solving them."
"This was my first session with the student and we covered ideal gas laws and gas pressures. The student seems to understand the concepts pretty well. When I walked her through the first problem or two she is quickly able to do follow up problems on her own. We are permanently moving our sessions to Mondays at 4pm."
"The student and I reviewed homework in preparation for a quiz or test that he will either have this week or next week. The student has no difficulty assigning oxidation numbers correctly, and he is able to correctly identify the oxidizing agent, the reducing agent, the oxidized reactant, and the reduced reactant in redox reactions. We discussed the basic structure of an electrochemical cell and how redox reactions result in the flow of electrons. We also discussed important differences in electric potential and electrical current."
"The student just had a quiz in class. We reviewed similar questions that were covered, but from the text book. The student seemed to be grasping the main concepts, and we went over some specific concepts for clarity."
"Went over the Lewis dot structure and certain exceptions to the octet rule. We drew some structures to represent the exceptions and drew resonance structures for certain molecules that share double bonds with neighboring atoms. The student understood what covalent bonding meant with respect to the octet rule and how that would affect the Lewis dot structure. We also went over some electron configuration problems just to touch up on some basics"
"In this session, we went over the student's test. He scored at 71% (C), which was an improvement over previous test scores, but was still not an acceptable grade to him. Most of his mistakes were minor errors: forgetting to convert units, minor math mistakes, and a few minor gaps in comprehension. We briefly discussed the next section that he will be covering in class, thermochemistry."
"Today, we jumped right into the material, and went over information you can pull from the periodic table: periodic trends, electron configurations, Lewis structures, and bonding. The student seems to be a very intelligent girl, and she learned the material we covered by critically thinking about the problem, and logically explaining the answer. She has a practice book to work out some practice problems."
"Chapters 1, 2 and 3. Covered basic chemistry principles like structure of atoms, covalent/ionic bonds, stoichiometry. She had a test the next day. She is going to solve a practice test after the session. No concerns."
"I helped the student out with a few problems she had concerning the material that she was just tested on. I then introduced to her the major concepts of thermodynamics, which was the next topic she was going to cover in class."
"At this session, the student and I went over dipole moments, Lewis structures, and polarity. We worked through homework packets from her class. She picked up the concepts really quickly and shows great potential in chemistry."
"Today was spent continuing review for the student's Chemistry test tomorrow. The focus was redox reactions in basic solutions (which are the most complicated form she expects to encounter) as well as calculating ion concentrations as a result of various aqueous reactions. After a few clarifying points on the latter in context of her practice test we worked in our last session, she seemed to relieved to finally understand. After that, we worked a few more examples of balancing redox reactions in basic solution, which she was able to complete without any significant trouble, even correcting herself when she realized she had lost her place. I'm confident she will do well on her exam given that she has covered the rest of her bases."
