Recent Tutoring Session Reviews
"Today we reviewed all the topics that were going to be on the student's exam tomorrow. I assigned him some practice problems regarding solutions. We looked at molarity and I asked him to write the formula associated with molarity. He had a hard time remembering the equation but after we discussed it in more detail he was able to write it without my assistance. Next he completed solubility practice problems. He did well on these assignments. I assigned him some problems regarding naming ionic compounds. He did not do well with this concept, so we reviewed the basic foundation associated with naming. After giving him a simple way to remember the difference between naming ionic and covalent compounds the student seemed to have a good understanding. I also taught him how to identify and name polyatomic ions. We discussed colligative properties and I asked the student to explain his knowledge of each concept. He struggled with this task. I explained each property to him in a simple way so he could get a better understanding. I asked him later in our session to explain to me in his own words about colligative properties, boiling point elevation, freezing point depression, and vapor pressure lowering. Eventually he was able to do this task with ease. We also discussed solubility, solutes, and solvents. He was able to explain these concepts to me in a very concise manner."
"The student is beginning to learn about Thermodynamics. The homework review revolved around solving for Gibbs free energy given changes in enthalpy and entropy at standard conditions and at non-standard temperatures as well. She is able to do the math perfectly fine, but has not had time yet to really drill down the idea of spontaneous vs. non-spontaneous. I sent her a photo of a good chart that helps break apart over what ranges things are spontaneous and non-spontaneous according to their Gibbs energy, enthalpy, and entropy."
"We reviewed metabolism: exergonic vs endergonic, catabolic vs anabolic, entropy vs enthalpy, kinetic vs potential energy, concept of free energy remaining constant unless enthalpy increases or entropy decreases, feedback inhibition, enzyme specificity, allosteric binding, etc. The student demonstrates a strong understanding of basic concepts and terminology and should do well on the upcoming quiz."
"She and I started the session by covering the four big classes of macromolecules. Their structures and functions were covered and various other concepts, such as polymerization of nucleic acids and lipids was covered, as well. She has a good grasp of these concepts and seems to be prepared for her exam tomorrow."
"Study skills - defining terms used in question paying attention to questioning words, e.g. How? Describe, etc. I help the student grasp the overall topic, so as to be able to explain the concept."
"The student and I covered passive and active transportation, including the different types and characteristics between the two. Next, we addressed isotonic, hypotonic, and hypertonic solutions. We made sure he could draw out each different solution. We also addressed what happens to cells in these solutions, and the differences between the solutions relating to concentration gradients. We also discussed the components of a microscope and what each component functions to do. Lastly, we reviewed all of his old material pertaining to cell components and their functions for review. He felt confident with the material by the end of the session."
