Recent Tutoring Session Reviews
"We covered enthalpy and Hess' Law that the net energy of a chemical reaction, such a going from Cgraphite to Cdiamond does not change even though multiple steps are involved."
"We covered stoichiometry. We practiced a lot of calculations with mole ratios, chemical formulas and molar masses. We got into limiting reagents a bit, as well. This session was almost purely a math practicum, but that seems to be what was needed."
"This was a complete review of chapters 1, 2 and 3 through section 3.6. Another quiz was given and the student missed half of the questions. The quiz and other study materials, 4 handouts in total, were given to him in order to help him study. This included handouts with fill in the blank covering sections 1.2, 1.4, 2.4 and chapter 3 in general. Subsequently, checkpoint questions were solved and explained in all three chapters. For homework, I gave the student practice questions, and checkpoint questions for section 3.7, 4.1 and 4.2. Now that an examination is looming in the horizon, the student has two marked quizzes to assist him in this capacity. Another area that was reinforced today is the concept of the atomic mass unit and how it relates to the SI unit, the mole."
"We worked on multi-step conversions. We used dimensional analysis to keep track of the units. In addition, we worked on identifying how many significant figures to use in the answer, and how to convert the answer to scientific notation. By the end of the problem set, the student was able to complete the problem from start to finish correctly, understand how the dimensional analysis worked, and knew how to identify the significant figures."
"The student and I worked on her Chemistry assignment, involving evaluating the atomic size/radius of atoms, cations, and anions; explaining the change in the atomic radius across a period/group based on the addition of protons and shells; defining the nuclear effective charge and emphasizing the shielding effect across a group of atoms; and identifying isoelectronic species and comparing their size. She understood the materials and was able to solve the problems by herself. We spent the last 35 minutes on SAT math, in which we discussed special triangles - a new topic for her. We worked on a few examples, and I will check her understanding in the next session. I also assigned a math section in her SAT book for her to practice."
"1. Test preparation. We worked through the student's study guide. 2. She was great today. She seemed to grasp the information very quickly."
