"The student has a test tomorrow, so we spent this session reviewing. He and I worked through some of the problems that his teacher assigned from the review session in the book as well as some other worksheets. We began by reviewing how to calculate an estimated bond length for a specific bond in a molecule using Lewis structures. Then we used Lewis structures and enthalpies of formation to determine bonds broken and bonds formed in a balanced reaction in order to calculate the total heat of formation for the reaction. We looked at some really tricky Lewis structures. In our last chunk of time, we revisited a section that we worked on last time, which was lattice energy. As always, the student knows he can email me or text me for quick questions anytime. Overall, the session went really well up. Good luck on your test tomorrow!"
"Today we compared and contrasted correlation and linear regressions. In order to make sure the student understood these concepts, I went through her class PowerPoint presentation on correlations. As we discussed the significance of each slide, I asked her questions to make sure she was grasping the material. She seemed to have a good understanding on the use of correlations and what signifies a negative or positive correlation. I also answered questions she had about when to use the t-test statistic and z- test statistic when dealing with correlations. I used her textbook to guide our discussion and explained the examples the book used to clarify any confusion. After explaining these concepts in a simplified fashion, the student was able to grasp these concepts quickly and relate them to other resources she had reviewed. Next, I provided her with an exercise/worksheet that tested her ability to determine whether a scatter plot displayed a positive, negative, or no correlation. She had some difficulty with drawing her best fit line, but after I explained the correct way to draw the line in relation to the plots, she began to answer the questions correctly. She also had to provide the correct value of r for each scatter plot. After I explained the range of values and how to correctly write these values, she provided the correct answer for each scatter plot. We also briefly reviewed her PowerPoint presentation on simple linear regression. I also gave some supplemental notes for her to use in addition to her class notes. After we discussed content material, I answered questions she had about her class assignments. I provided some guidance on where to locate the material to assist with the assignments. I was pleased to know that she did well on her previous assignments, and her professor noticed a difference in her performance."
