Recent Tutoring Session Reviews
"In this session, we dealt with the concept of tension and compression in truss members. We determined how to prove the tension/compression - tension pulls away from the pin, and compression pushes on the pin. We then worked a problem in the book to solidify the concept and tried out a zero-force member problem from some materials that I gave to the student. He seems to have a very solid grasp on the tension/compression concept, and he will solidify that with his teacher as soon as he can."
"During this session, we studied for the student's test that is tomorrow. We reviewed the differences between elements, compounds, and mixtures. We also talked about the differences between homogenous and heterogeneous mixtures. Then, we reviewed phase changes and energy changes and how to model that on a heating curve. We covered a lot of material, but she understood most of it very well and after working through everything, she seemed very confident in her abilities to explain all of these concepts."
"The student was finishing a homework assignment that combined vectors with projectile motion. It gave us a chance to probe projectile motion, for what it means and how to work with it. We did problems with only horizontal velocity and with a launch at some angle above the horizontal. She seemed to take to the material readily and, with some more practice, should do fine with it in this class. On Monday, we covered Algebra II topics like polynomials functions and solving quadratic equations by factoring, completing the square, and the quadratic formula. Wednesday, we covered further problems with projectile motion. She needed more help with the idea of separating the horizontal and vertical directions, and on defining what was known and unknown. We used her homework problems to explore these topics, and it turned out well."
"Today we continued on with the second part of the review for chemistry. The review is based on a continuation of the topics we studied yesterday--quantums. We worked with electromagnetic rays, and I helped the student understand how to solve problems with the speed of light, wavelengths, and frequency. As always, he understood the concepts and how to solve the problems quickly. We also worked on concepts he's studied before--isotopes, how to find average atomic mass with isotopes, and their percentages, as well as the differences among protons, neutrons, electrons, mass number, and average atomic mass. At the end of the chemistry review, we went over all the concepts all over again, and I was confident that he knows how to do everything. For the remaining 20 minutes, we worked on his math homework, which was focused on using imaginary number i to solve problems."
"The student and I reviewed significant figures (counting leading, middle, and trailing zeros), rounding to match the number of required significant figures, and calculation of density-mass-volume. We went over converting between decimals and scientific notations, and applying significant rules in addition/subtraction (counting decimals) and in multiplication/division (counting significant figures). She comprehended the new materials well."
"The student and I covered nomenclature of acids, covalent compounds, and ionic compounds. I gave him several pages of notes on the mathboard to refer to before his test on Wednesday of next week. I also provided him with a page of polyatomic ions to memorize as well as a list of metals that can have various charges. He seemed to get a lot out of the session and to gain confidence as the session progressed. We have set an appointment for Tuesday, and encouraged him to schedule another session before that time and day so that he has more time to review before his test. I told him that if not, he should at least work on the problems on his own before we meet next. If he has completed them without difficulty, we can review practice problems that I will prepare."
