Recent Tutoring Session Reviews
"We went over new material on the laws of reflection and refraction, and ray tracing/mirror/lens equations for convex and concave mirrors and lenses. We went through examples of drawing the rays for each type of system and using the formulas to determine image distance, height and magnification. A few things had to be clarified, but overall, she seems to have a good understanding of these new concepts. I suggested going through past quizzes/tests/homework and making sure she can set up solutions for each problem. Anything that she has trouble with, we will go over next time to review for her final exam."
"The student and I worked on lenses, including reflection, refraction, images, thin lenses, and ray diagrams. He seemed to have a pretty good understanding of these topics; he just needed a little bit of extra help to get him over the top. We spent a small amount of time going over the equations, mostly Snell's Law, and then went into working some examples. He had no problems understanding the math; nearly all of his were conceptual. We discussed determining real and virtual images, magnification, and how to use ray diagrams to solve problems. Nearly all of the problems required some use of the thin lenses equation, and a conceptual understanding of what the problem was asking. We worked through reflection, refraction, and critical angle questions with ease, and took a little more time figuring out the lenses problems. He also showed me his homework, which he had missed maybe 2 questions on as far as I could tell, and we worked through those problems together. He was very focused and determined throughout the session, and I would anticipate that his upcoming quiz over these topics will go pretty well."
"We reviewed for the upcoming test. We focused on diffuse vs smooth reflections and concave mirror reflections. The student had a good understanding of most of the material but needed further explanation of how to solve for image magnification and distance."
