Recent Tutoring Session Reviews
"This was our first meeting in a few weeks. Student has been doing very well in physics and typically scores very much above average on her quizzes and exams. She recently had difficulty with a test on optics, but that is because she was so worried about ray diagrams that she spent a majority of her study time on that skill and not others. She performed very well on the ray diagram section of the test. We reviewed her test and spent a good amount of time on a Snell's law problem. She understood the corrections that needed to be made and still ended with a 92 average for the marking period. The electrostatic unit of the class went very well for her, and now the class is being introduced to the fundamentals of circuits. We had a general discussion about the basic concepts she will have to be familiar with in these chapters, such as Ohm's law, circuit elements (resistors, batteries, capacitors), in series and in parallel circuit elements, and current. We also discussed the mechanism of how batteries power circuits and the basics of Kirchhoff's laws. I did not want to get overly ahead but we had a productive discussion that will allow her to understand the concepts as they are introduced to her in class."
"We did review problems for the student's upcoming final exam. Topics included magnetism, magnetic flux, lenses, mirrors, reflection, and refraction."
"We reviewed the student's Chapter 19 review assignment (Magnetism/Magnetic Field). We also reviewed Precalculus chapter 13.3 homework (Probability)."
"We covered RL, RC, and RLC circuits. We went over three basic problems I had designed. Solving for the total current in an RL circuit, considered the contribution to the electrical impedance by inductors and capacitors. We also covered the currents, charges and voltages for a RC circuit at various moments, directly after a switch is closed, after the capacitor is charged, directly after opening the switch again. We also looked at a RC circuit charging and discharging."
"We built one of the student's labs, a coil of wire that will spin like a motor in an external permanent magnetic field when current is run through it. She still needs to twist a couple wires together, but then it will be ready for testing. Tomorrow we will meet again to work through the questions and start building the next lab, testing the strength of an electromagnet. The student is fully engaged with the project and taking thorough lab notes, so I think she has a good understanding of how it works. We talked about magnetic motors last time, in the context of a demonstration of this lab, so the lab questions next week will be a review of material she has seen. I think it will go very smoothly."
"In geometry today, we started talking about volumes of 3D figures: cylinders and prisms. In biology, we talked about plant-like protists (algae). We discussed how they store food, their pigmentation, reproduction, uses, cell wall composition, etc."
