"In calculus, we practiced taking derivatives using implicit differentiation. We also practiced using implicit differentiation to find the second derivative of a function. We talked about how to simplify a second derivative using the first derivative function. In physics, we practiced drawing all of the forces acting on an object. We went through finding the vertical and horizontal components of a force vector using the angle and magnitude. We practiced setting up the sum of the forces in the x- and y-directions for an object with a net acceleration. We went through the elevator problem for finding the acceleration as it starts to move. We talked about how to choose a direction to draw the acceleration, and how the sign of our answer will tell if the acceleration is in that direction or the opposite direction. The student is doing well drawing force diagrams and determining all of the forces acting on an object. He is also doing better using implicit differentiation."
"In our first session, we worked on scientific notation for his math class. This ranged from a simple moving of the decimal point to a problem combining 3 numbers in scientific notation within a fraction, which required multiplication, division, and adding and subtracting powers of 10. Although some of the questions he had to answer were tricky, he seems to have a pretty good grasp of scientific notation. He is a bit stronger now than at the beginning of the hour."
"In our last session we worked on the student's English packet and finished the assignment for the due date. We moved on to his multiplication worksheet and completed one of the sides. He showed me a quiz that he has an opportunity to correct in order to get points back , we plan to work on this quiz. He did a really good job slowing down and writing neatly and clearly in our last session."
"In preparation for this session, I had a packet of benchmark problems for the student's grade level. We worked through a good assortment of problems: boxplot, probability, fractions and operations, word problems, ratios and proportions, and sample sets. She worked through the session well. She has good intuitive sense in seeing the solution path, but needs to write down and set up problems. As soon as she does, she's very able to process through to the answer. The key is to write it out."
"In the beginning we were changing trinomials into the perfect square of binomial. Next we were changing standard form of quadratic function into the vertex using this technique. After that we stated the coordinates of the vertex. We solved the applied problems and identified the equation of quadratic function in standard form using given graph. Next we review how to solve the quadratic equation with complex roots using quadratic formula. Moreover, we calculated a power of i. Next we solved the applied problem on maximum of the quadratic function. We calculated maximum using vertex formulas and a function formula."
"In the session, we focused primarily on confidence intervals. Specifically, we calculated confidence intervals around a mean using t and z. We covered how confidence intervals are affected as sample size increases, CI level increases, and margins of error increase/decrease. We also briefly discussed a group project that the student has. In the project, the instructor would like for students to use pre-existing data (e.g., census data, other archival data) to examine some relationships. I offered some suggestions along the lines of the healthcare topic that his group was focusing on."
