Recent Tutoring Session Reviews
"During this session we first reviewed how to calculate the total energy required to change the temperature and physical state of a substance. We worked on energy problems from an assignment sheet and used the diagram method we had discussed last week to map out and complete the problem. We also discussed the concepts behind his homework assignment, which covered intermolecular forces and their effect on solubility. The student should receive a grade for his quiz by next session, when we can review how the diagram strategy went during an evaluation setting."
"Today we reviewed several practice chemistry questions which mostly consisted of open answer questions. The topics covered included calculating and interpreting densities of liquids and objects, explaining/designing experiments, and particle energy in different states (solid, liquid, and gas). The student seemed confident with the material but would benefit from practicing more open answer questions which require more critical thinking skills rather than just a one or two word answer. Overall, he was positive and motivated throughout the session."
"We finished discussing endothermic and exothermic reactions today, and covered specific heat through the formula q = m C delta T. The student was already very well versed in using this formula, and with some Socratic prompting, demonstrated strong understanding of the concepts it represents. I alternated between assigning problems in which he used the formula to identify temperature changes and unknown metals, and conceptual questions such as "One way to identify a pure gold coin as opposed to fake or impure gold is to rub it briskly in the palm of your hands. Real gold will become slightly soft. Knowing this, does gold have an unusually high or an unusually low specific heat?" (Low, because even the small amount of heat you can generate in the palm of your hand can heat a piece of gold enough to melt it slightly). He did extremely well with today's concepts."
