Recent Tutoring Session Reviews
"The student was assigned problems dealing with vectors and their components. Due to her grade level, the student would have had to undergo the daunting task of hand measuring and graphing the vectors to determine the horizontal and vertical components of the given resultant. Tonight I taught her how to use very basic trigonometry in terms of a right triangle to solve for the components of the resultant vector. We focused in on the background information of SOH-CAH-TOA and how the acronym relates to individual equations and the parts of the triangle. We then simplified this to state that Hcos0=x and Hsin0 = y (letting 0 be Theta). I explained that this was only good for vectors stemming from the x-axis. We then discussed the direction of the vector and how that decides the direction of the components. I also explained how to input this information into the calculator on her phone and the calculator at school. The student did remarkably well with this information and was very quickly and easily able to solve for the x and y components of the given resultant vectors. We completed all of her homework problems and then moved on to some additional practice problems. I feel confident that by the end of our session, she will be able to utilize this method on her own."
"We continued to study for the next test. We worked through some practice problems. The student did better today. We discussed some strategies to help speed up the problem solving processes. We also discussed a method for determining charge on individual capacitors."
"Went over nomenclature for carboxylic acid derivatives, how structure determines reactivity, stability of carboxylic acid derivative leaving groups after nucleophilic attack, reactions of acyl chlorides with alcohols and amines to form esters and amides."
"We covered molar masses and empirical formulas. The student was only struggling a little with remembering how to determine the empirical formula with mass of elements. His attitude was positive and we were able to get one lesson done."
"We covered more of what was on the homework, focusing on a variety of topics, including solubility, boiling point and freezing point changes, 100% dissolution of ions, osmotic pressure, the van't Hoff factor, and more."
"We covered more on electron configurations and periodic trends. When working with periodic trends, I helped the student out by taking a periodic table and drawing an arrow to go up and to the right. Above the periodic table, I wrote atomic size decreases, first ionization energy increases (IE 1), electron affinity increases, metallic character decreases, and electronegativity increases, as all of these change in this manner as you go up and to the right. I also explained electron configurations of charges. Using this information, I also helped her understand paramagnetism and diamagnetism. With her work of her other problem sets, I saw that she was setting up problems for ideal gas laws and heat exchange properly for her test on Friday."
