Recent Tutoring Session Reviews
"We covered more thermochemistry material specifically delta H of fusion, delta H of vaporization, and phase change energy calculations. We also did review problems involving q=mc(deltaT) which was covered last week. Some problems initially gave student A trouble because he was confused on how to start them. He made errors such as converting from grams to moles of water on problems where the conversion was not necessary. However, after some thinking, he was able to identify his mistakes and solve the problem correctly. Both the students seem to understand the concepts of thermochemistry well. Most of the errors were math-based, such as forgetting a negative sign or converting from J to kJ incorrectly. After we covered all the new material, we did more challenging, college-level problems concerning what was covered last week. They were able to solve these problems because they had a fundamental understanding of q reaction = -q lost. They have a test coming up this Friday, and the problems on the test are essentially the same types of problems they have been doing in their homework packets. I believe they are well-prepared in terms of knowing the concepts. If they pay close attention to detail during the calculations and re-check their work, they should do well."
"Yesterday, we worked with a new concept, the mole. We discussed and completed a packet and worksheet using mole-mass and mass-mass conversions. We also studied which types of organization varies in a chemical reaction (mole, molecule, volume) and what is conserved (mass, atoms). I then gave the student a quick preview of mole-mole calculations and stoichiometric real life applications."
"We reviewed upcoming test and quiz problems sets; reviewed concepts of PPM and mass percentages; identified ways to assist the student in understanding concepts of chemical concentrations; asked the student to identify weaknesses on last quiz; and made plans to more effectively link tutoring with quiz materials and dates tested."
