Recent Tutoring Session Reviews
"We worked on solving and graphing natural logs, logs, and exponents. In each section we went through the various types of issues and how they adjust the graph from the original problem."
"After a recent bad grade on a test, his teacher is allowing him to do a make up the test, so our goal for tonight was to review as many of his wrong answers as possible. The test covered a variety of geometry subjects, including graphing, transformations, and similar shapes. We quickly identified some issues with keeping the x- and y-axis straight, so we did some extra practice of graphing points. I introduced the idea of proportions, a word he has heard in class, but not yet explored a whole lot, for dealing with similar shapes. He was very confused on the whole topic, so we started from the beginning: we defined similar shapes, I created and completed some examples for him, and then we worked together on the test questions. I think it helped to put a name to the idea of proportions, as he seemed to grasp it pretty well. I gave him some suggestions for approaching various problems, such as breaking a problem apart into steps. I will continue to use that approach and others we introduce regularly, so that he can develop a routine."
"The student and I prepared for a quiz he is having tomorrow in his math class. We used a review sheet from his teacher as a guide. We started by going over composite and inverse functions. He did well on the quiz covering this area, but he wanted extra review since it was the first topic in the chapter. After a brief review he was able to use composition to determine if functions were inverse functions. We also reviewed how to write logarithmic equations in exponential form and how to write exponential equations in logarithmic form. I showed him the formulas for this and suggested that he practice writing them so he knows them for the quiz. We also reviewed the change of base formula and how to apply it, evaluating logarithms, and finding asymptotes. The student had some questions about graphing translations and we spent time discussing the different translations and how they impact the graph. We finished by discussing compound interest and radioactive half-lives. For the compound interest we started by reviewing the formulas. I suggested to him that he also write these out to make sure that he knows them. He completed the chart in the review for different rates of compounding and continuously compounding interest. The final problem on half-lives was something that he wasn't familiar with, but we were able to walk through it and he understood what he was being asked."
"The student needed help with Correlation and Regression to add to her exam prep. We covered both these topics and tried a few problems to prepare for the exam."
"We went over different types of distribution, z-tests, t-tests, binomial tests and probability. We are currently setting up her Statistics and Psychology tests for me to proctor in the upcoming weeks. She has practice problems to look over before our next session."
"We went over probability problems that covered sensitivity, specificity, geometric distribution, and the hypergeometric distribution. The student understood how to do the problems after he was shown."
