Recent Tutoring Session Reviews
"We went over the student's new material and talked about how to find moles and molecules from grams. She has been practicing dimensional analysis on her own so her ability to understand this part of her chemistry class came quickly to her. She also needed to find molecular weights of compounds and she was able to find that very easily. Her understanding of chemistry is getting much better than when I first started working with her."
"We focused on one main topic with the student today. This was the definition of molecular mass, and in particular, working with converting units. I started by giving a small lecture on how to convert from one unit to another. I then showed him several common conversion factors such as inches to feet, dozens and eggs, and finally what a mole represents. We then tried to do simple conversion problems such as asking if someone had 36 inches, how many feet would that equal to. He had no trouble figuring this out."
"We went over the student's previous quiz and exam. She did pretty well on her exam 90% and did well on the quiz. She knows the material pretty well but the questions are worded pretty oddly and it's often you have to find the "best" answer. So we reviewed the material and talked through how to decode them and find the best answer. We went over naming ionic compounds. She has a quiz next week so we did the review questions her teacher gave her. We also went over orbital hybrids."
"We reviewed topics from the chapter they just finished in class. The topics include using Avogadro's number, and stoichiometry - converting from moles to grams and vice versa. We also went over how to determine limiting reagents and finding molecular formulas."
"The student's final exam in the course was the following week, and his teacher had provided a study guide with a long list of questions and review topics, many of which were centered around atomic structure and properties. Since it was impossible to review all the topics on the list, and because he had already reviewed some of the topics recently, we chose some of the topics to review together, including atomic and molecular structure, electromagnetic radiation, and conversion factors. Because he had not done calculations using conversion factors for a while, we spent extra time on this topic, emphasizing the use of dimensional analysis. While he initially had some trouble with questions involving calculations, he soon grew more comfortable as he practiced a few. Timmy ended up earning an A- on his exam."
"We covered colligative properties (adding solutes to solvents) and worked through several assigned problems. The student has a good understanding of the concepts."
