Recent Tutoring Session Reviews
"Tonight we went over lab seven which was developing a Poisson Model of data used in an earlier lab. We were able to discuss the output and how to interpret the model validation."
"The student is currently learning conservation of energy in collisions. We worked on an inelastic collision problem that required a long derivation of an equation from the conservation of momentum and conservation of kinetic energy. Though it did take up a lot of time, I felt like it was an important thing to do together, so that he has an idea how to approach something like this in the future. We finished the assigned homework that he had. I think he has a good understanding on this material."
"Today's session was used to finish up the student's ecology unit. We discussed K versus r selection in animals as well as the important differences between exponential and logistic growth in populations. We also looked at how life tables, survivorship curves, and reproductive tables, can provide insight into how populations reproduce and maintain population numbers. The session finished by looking at how human beings have managed to increase in number with the rise of the industrial age, and how our growth will likely continue. She did a great job understanding the material, so I was able to test her understanding of the equations provided to explain population growth. She was able to show me how the portions of the logistic equation translate directly to population growth. I feel she will have no problem with her test tomorrow covering ecology and population dynamics. We plan to meet up next week in order to cover the new material covered in class."
"Went over electromagnetic forces and potential between charges. The student has a good understanding of the material and will have a solid understanding with more repetition. I gave a couple problem solving/test taking strategies: "always start with the simple equation and add in what's given from the problem.""
"Worked on the Henderson-Hasselbalch Equation, preparing buffered solutions, buffer capacity, finding concentrations of component species of a buffer at different pH."
"We covered topic 3 of Chemistry SL. This included : - All trends in the periodic table. - Properties of groups and periods in the periodic table. - Reactions of elements with waste or oxygen. The student seems to understand the material reviewed. He can solve all of the practice problems successfully. Additional practice materials for both Paper 1 and Paper 2 and the study guide will be sent before the next lesson."
"The student and I discussed population dynamics, carrying capacity of natural systems, and human populations. I think that the student is bright and wants to reinforce the concepts she reads about and learns in class in more colloquial terms."
"We covered the energy transfer between photosynthesis and cellular respiration via glycolysis, the Krebs cycle, and electron transport chain. Also, the necessary ingredients for making ATP, which electron carrier molecules are reduced and which are oxidized."
"The student and I mainly discussed the problems she's been having with the course thus far. We also went over some practice multiple choice questions in anticipation of the AP exam. She is a very intelligent and motivated student, and I am glad to report that her interest in environmental science extends beyond the course."
"We went over scientific experiments such as SDS-PAGE gels and ion exchange columns. The student was very confident with the material. We went over it and she followed along great."
"We covered basics of ecology, including concepts of natural selection, founder effect, and bottleneck effect. We also went over some Hardy-Weinberg problems."
"Today, we covered the basics of periodic law and atomic structure. We focused mainly on electron configuration predictions, using the periodic table as a guide. The student was struggling with keeping the pattern of how the electron energy levels filled straight. The strategy we used to handle this particular material is based on the visual structure of the periodic table, specifically how the elements are already organized in the order in which their electron shells fill. By the end of the session, he was able to figure out the valence electron configuration of any element on the periodic table, provided he followed the pattern we outlined. He will need a little more practice before the method will become rote memory, but he made a big step towards that today."
