Recent Tutoring Session Reviews
"We spent the bulk of the session preparing for the student's upcoming test on covalent and ionic bonding/nomenclature/Lewis Structures. First I explained the difference between covalent and ionic bonding by reminding her about the trend in electronegativity across and up the periodic table, showing how atoms with similar electronegativity will share electrons and form covalent bonds, while those with big differences will transfer electrons and bond ionically. Then we worked on covalent nomenclature. We went through Lewis Structures quite methodically, and I had her count up the valence electrons of the constituent atoms before trying to draw the structure. After 4-5 practice problems she really was understanding the material, and I am confident she will do well on this part of the test. Next we talked about ionic nomenclature and Ionic Lewis Structures. We closed by discussing some math concepts, namely how to find the slope of a perpendicular line given the slope of a line."
"We covered topics on how to find pH, H+ concentration, molarity, and dilution. We went over and completed the two assignments the student had regarding these topics."
"I helped the student prepare for her test on solutions. We primarily focused on colligative properties, but reviewed everything listed on her study guide."
"Worked through a practice final exam. Reviewed topics from the course of the whole semester. Discussed likely subjects to be tested. Revisited growth factor pathways, citric acid cycle, fermentation, prokaryotic transcription/translation, driver vs. passenger mutations, and eukaryotic transcription."
"The student had an upcoming quiz on the initial 3 sections of her current chapter. We reviewed the key concepts and terms. Afterward, I quizzed her on several of them to make sure she had a firm grasp before we left."
"We reviewed transcription and translation in a cursory sense today to supplement what we reviewed last session. We then delved into greater detail regarding translation, and the steps of initiation, elongation, and termination. After this, we started to review the regulation of gene expression. We started to go over the trp and lac operons in E. coli."
