Recent Tutoring Session Reviews
"We started with thermochemistry, enthalpy and work. It was a little difficult to go over the practice problems because I couldn't see them the problems. However we will work that out before our next sessions"
"Today we were working on her final review for the trimester. She had a review packet that she had started, and we finished working through it together. I gave her some tips and tricks to help her remember some of the concepts that she needed to remember, and I think just going over it with someone helped her a lot. She seemed confident by the end of the session in her abilities to do well on the test."
"Today we completed their current homework assignment concerning periodic trends, electronic configuration, and related topics. Having completed more than half of the assignment during our previous session, we were able to take our time and reason through the remaining questions, which went very well. I stressed to both students the utility of memorizing the general trends of electronegativity, ionization energy, electron affinity, and atomic radius across the periodic table. I was also able to restate and clarify the definitions of a couple properties like electron affinity that were still a little hazy. We were entertained by a few "lateral thinking" questions presented on the assignment that asked for application of logic in the context of the question rather than assuming some sort of mathematical relationship. Overall, I feel they have a very good foundation for understanding these properties and are able to make reasoned conclusions."
"In this session, we reviewed chemical equilibria, acid-base equilibria, buffer solutions, and solubility equilibria for the student's test. He had a very good handle on most of this material, but we hadn't reviewed it in awhile. He did need some help with buffer solutions and some of the solubility equilibria. He was feeling confident after the session."
"We worked on the student's lab covering the heat of formation of several reactions. We went through the calculations and tried to determine heats of formation, q, and moles used in a solution. The lab did not have sufficient instruction for all of the steps, but we were able to determine some of them from previous work we had done with calorimetry."
"We covered more net ionic equations from the online problems he has assigned to him. The student was noticeably more comfortable with the topic, as before he had been hesitant leave a given component out of the equation. This time, he was a little more practiced and knew to identify the parts of the reaction that don't change. As far as knowing that, he had a solubility table to refer to, so he was also better at navigating that for necessary information. I left him with more ionic equations and solubility questions to review next time."
"We went over Gibb's free energy, entropy, and how they relate to the spontaneity of a reaction. We went over a handout given to her in class. She seems to be understanding the concepts. I have assigned her the rest of the practice problems in the worksheet given to her in class and I will give her more difficult practice problems from a textbook used in my university next session."
"The student worked on her two homework assignments that had to do with intermolecular forces and networks, one was a book assignment and the other was an old exam packet. She just needed a few explanation of concepts and after that she understood the material pretty well. I gave her a few links that explain surface tension and network solids pretty well, and the links also have charts to help her remember the differences in types of solids."
"We went over current homework that covered the relationships between wavelength, frequency, and speed of light as well as the photoelectric effect and Planck's equation. She was able to understand and apply this formula readily. I did a conceptual review at the end of the session to reinforce the homework problems and serve as a base for what she is currently doing in class, which is bonding. Next session will cover emission spectra and energy levels in preparation for a deeper understanding of quantum mechanics."
"In this session, the student and I went over Lewis structures of various compounds, and went through several lab reports to finalize calculations and conclusions. Some of the Lewis structures had tricks or monkey wrenches thrown in, but she did well in maneuvering these. She has been improving her grade, and we hope to have her grade up to a B before the end of the semester."
"The student and I went over equilibrium problems: working with Le Chatelier's principle, solubility, equilibrium constant, etc. He says calculus is easier to comprehend and apply the knowledge he's gained so far. At the moment, he needs help more with chemistry; therefore, we switched our focus to this subject now."
"First, the student took a practice test over naming ions and writing out their formula. I highlight all the ones she got wrong and some additional ions. I'd like her to study these ions and I will quiz her on them again on Sunday. After, we went over stoichiometry problems that involved using a reaction formula. I gave her tips for how to check if her answer made sense by keeping track of the units when completing the problem. I also showed her how to make a estimation of what the answer should be before completing the problem. That way if the math was done incorrectly it will be obvious. I can definitely see some improvements in her ability to think critically about the problems in this section! Once she nails down the names of ions, we should see some improvement in her grades. I have given her 'challenge problems' that she should work on that will further develop this skill."
