Recent Tutoring Session Reviews
"This was my first session with the student. We briefly went over her current standing in the class; how assessments are given in the class, relative proportion of the course grade given to homework and tests, and frequency of assessments. After our review of her overall situation, the student and I spent the remainder of the session doing her current homework in preparation for her test on Friday. We reviewed discrete probability distributions, binomial distributions, geometric distributions and briefly the Poisson distribution. The student struggled initially with understanding what concepts like the mean/expected value of a probability distribution represents, but after repetition and using multiple approaches to explain the material to her she did much better. While the concepts are not immediately intuitive to her, I am optimistic about the student's capability to do well in the class moving forward."
"Worked on problems that use the t-test to compare a pair of sample means from samples with a small (<30) number of individuals, then reviewed an in-class problem on a t-test with paired samples and discussed the difference between the two types of problems. Then reviewed the probability quiz to identify problem areas and examine where time is lost during testing."
"We worked on a handout on standard deviation and normal distributions. The student did not know what a standard deviation was or how it was calculated, and was uncertain about the nature of normal distributions, so we began by reviewing both. I explained that the standard deviation is used to represent the amount of variability in a set of data, and is the square root of the average squared distance to the mean of a data set. We used the fact that standard deviations separate normal distributions into known portions (e.g., the fact that 34% of data points in a normal distribution lie within one standard deviation of the mean) to calculate the probability that a given data point will lie between two particular values. Half of the handout did not require a calculator, and the student moved through those questions reasonably well once he understood what a standard deviation was and how it related to the normal distribution. He also wanted to understand the purpose of standard deviations, and I explained how they are used in scientific research to calculate the effect size of an effect that is being studied experimentally."
"Today we practiced solving 2x2 systems of equations, and we discussed different methods such as the graph method, the substitution method and the elimination method. The student picks things up very quickly, and with practice should be able to excel at algebra."
"The student and I went over working with negatives and substituting values for variables. He works well and is excellent with the mental math. We also went over science vocabulary. He is really improving on his previous issue of dealing with negative numbers."
"We worked out how to find equations for tangent and perpendicular lines to curves and did examples of the power, product and quotient rule. The student and I also discussed her calculus homework assignment."
