Recent Tutoring Session Reviews
"This session we worked on chemistry because the student said she is doing well in algebra this week. She worked on her lab homework. The task was using mole ratios to determine the amount of product formed from a reaction with a given amount of reagent. She didn't understand the concept of the problem when we first started. She has used similar formulas in the last few weeks so I believe the issue was more in the wording of the problem. As soon as she understood the context and completed a few problems it went a lot more smoothly."
"Tonight we covered vapor pressure, energies of solution, and factors that affect solubility. We reviewed Le Chatelier's (LC) principle and solution composition (molarity, molality, and normality). I advised the student to complete the quizzes on LC principle, as this topic is heavily tested on the MCAT."
"For this session, we did practice problems involving percentage composition, empirical formula, and obtaining molecular formula from empirical formula. I offered the student strategies for solving these types of problems. The student has made great improvements in his ability and confidence to tackle chemistry problems."
"In this session, we covered the significance and numerical values of the four quantum numbers and their relation to electron configurations. The student then applied that knowledge successfully to practice problems. The blackboard work we did in this session seemed to significantly improve his understanding of how quantum numbers relate to electron energy and position. The combination of visual presentation (diagrams and writing) and auditory presentation (talking through the process) considerably helps with his comprehension."
"We went over how to draw Lewis dot structures. I went over the step by step processes on how to draw the structures for certain molecules. I followed up with some practice molecules that I asked him to do himself on the whiteboard, and I pointed out any mistakes he made along the way."
"This session we worked on preparing the student for her test tomorrow. We spent the whole time solving problems of empirical and molecular formulas. By the end of the session, she was solving the problems completely without any guidance, which was a real improvement from when we started the session."
