Recent Tutoring Session Reviews
"Reviewed/Finished covalent bond material in PPT_ChemicalBonds_14 and thoroughly discussed differences between ionic and covalent bonds; Went over WS_IonicBonds and finished WS_CovalentBonds together; The student improved in drawing molecular structures, and was able to expand that idea to drawing more complex molecules based on valence electrons (beginning discussion about formal and partial charges); Assigned WS_Unit03Review"
"The student did great today. He worked on an assignment for his science class where he had to write 15 multiple choice questions and five open ended questions, and provide the answers. We worked together to word questions differently and provide details in his answers. He listened attentively and completed the assignment. He's doing great."
"This session was on the day of the student's first lecture. I spent the first half of the session on the professor's PowerPoint, going through definitions and providing context and examples, particularly examples that professors use to stump students. The second half of the session was spent running dimensional analysis problems and giving an introduction to chemical properties. The student has a solid grasp on the material."
"I covered scale, angular position, concave lens, velocity, motion map, and graph. The student was struggling to interpret the graph a little bit. The student exhibited great attitude during the session. I showed the student how to use scale and study habit during classroom. The student had B on her first test. She appears to be a good student and is eager to learn. She paid attention and asked questions during the session."
"I covered the focus of the student's curriculum for the week and for the exam the following week. This entailed VSEPR theory, orbital shapes for covalent molecules, the differences in bond types, the octet rule, hybridization of orbitals, Lewis Structures, Arrhenius acid naming, ionic compound naming, and other related keywords and ideas. The student struggled most with visualizing the 3D geometry of the orbitals and being able to draw it on paper. By the end of the session, she could draw and identify orbital geometry while understanding the relation of electron geometry to bond angle ."
"I did a problem for the student that was basically a limiting reagent problem crossed with a precipitation reaction. I showed him how to balance the equation, calculate the moles of each ion from their volume and molarity, select one at random and calculate the amount of the other required to react with it. In this way, you determine which one is the limiting reagent. Once the limiting reagent is determined (if you didn't happen to luck out and pick it randomly) you determine the amount of the excess reagent that is consumed. That which is not consumed is the amount (moles) left in solution. Dividing that by the combined volume gives the final concentration of the other ions left in solution. I also showed him how to get the number of those ions in the solution by using Avogadro's number as a conversion factor."
