Recent Tutoring Session Reviews
"In this session, I continued to help the student prepare for her Chemistry quiz that is tomorrow. Since her teacher mentioned that questions in a practice SAT II Chemistry book would be similar to those on the quiz, I had her go through relevant practice questions. After she completed each question, I reviewed her answer and used it as a means of probing her understanding or a jumping off point to supplement her knowledge."
"This was our first session, so we discussed what to expect out of tutoring sessions and what material she would like to cover. We then went over a quiz she had gotten back in class to make corrections."
"The student and I went over her last practice quiz covering the conversion of moles, molecules, atoms, and grams. She was having difficulty determining which conversion factor (Avogadro's number or molar mass) to use. I made a little study guide for her and explained the definitions of each conversion factor. This seemed to help clarify which conversion factor she should use, and how to use it. We also went through percent composition problem and determining the empirical and molecular formula. She understood all the steps to find the empirical formula, but initially couldn't figure how to find the molecular formula. Once she saw me go through an example, she understood how. The root of the problem seemed to be a lack of understanding of the definitions of a mole, a molecule, an atom, and a compound. I created a quick quiz that went through the definition of each of these so she could use it as a study guide."
"We reviewed for the student's AP chemistry test on Kinetics. We did a basic overview of rate law, rate determining step, half-life, and reaction mechanisms. I pulled up a study guide for her to look over and also gave her some additional practice problems. We did some practice problems with half life reaction mechanisms, and potential energy of reaction in the session."
"Discussed changes of state, the process names of going from different states. Explained concept of vapor pressure and adhesive and cohesive forces. Explained affects of temperature on these forces. compared properties of substances with respect to intermolecular forces. Went into detail about the concept of vapor pressure. Assisted the student in his Chem homework."
"We continued to go over homework problems from chemical equilibrium. The student is on track with the homework problems and has maintained good progress. She is able to tackle problems that combined multiple concepts and needs less guidance. Overall, great session."
"We went over the dipole moments, polar-non polar molecules and the VSEPR theory and Lewis Structures. Solved many questions related to these topics and practiced the materials. I saw her performance on the test and gave her some comments to improve. She had some problems on the dipole moments and the polarity and I gave her some practice problems and we worked on them together."
"Today we worked together on a new assignment concerning electronic configuration, atomic structure, and properties/trends of elements in the periodic table. Many of the topics/questions we worked were not yet covered in class, so I was able to give a few definitions and explanations of concepts such as effective nuclear charge and electron affinity. The students have another 10 days to complete the assignment, so we have planned on completing the assignment during our next session, during which I will also bring up some strategies for determining the electron configurations for tricky elements in the d-block."
"The student has a test tomorrow and we reviewed various concepts and problems in preparation for this exam. We covered chemical bonding, polarity, and energies of formation of binary compounds and well as the material we covered last week which included periodic trends."
"Today was our first session, so we discussed the student's current strengths and weaknesses in the class and began to review concepts already taught in anticipation of the final in a few weeks. I'm getting a good understanding of where she can improve, and I think a big piece is being able to articulate what's in her brain :). We discussed a general plan to prepare for the semester final and master new concepts as they're taught. We will meet next Sunday to review old tests, etc. and put together a specific strategy for exam prep."
"We covered the greatest positional probability, the difference between delta S of the surroundings vs delta S of the system and when to solve for the different variables based on the question stem and information provided. We then went through a series of old written response questions that were given in a packet form by the teacher. Then briefly went over a few multiple choice questions from an online test. The student has the content knowledge."
"Today we looked at an unknown identification experiment that the student did in her lab. Her experiment was to observe the solubilities of four known compounds in water, ethanol, hexane, hydrochloric acid, sodium hydroxide and apply those results to identify compounds of similar structures. It was a challenging process as many of the possible unknown compounds were similar in structure but the student definitely learned a lot about how bonding and structure affects solubility in compounds with known bonding and structure."
