One thing that I noticed I explained, but the article did not seem to have more emphasis on was "the units of measurement". This is notion is only part of the mathematical language that Bill used in the lesson. Other than Ann's understanding of the proportionality among the quantities, I believed that if Bill focused a little bit more on using the correct unit of measurements behind the values he stated could have possibly made a difference in Ann understanding what the quantities were that she was using in the mechanics. For example, instead of saying "you divided 100 by 10" maybe Bill could have said, you divided the total distance 100 ft by the speed of 50 ft/sec" in his discussions/explanations with Ann.

I made the same comment in my essay. I don't think the the units themselves would have made the biggest difference, but if Bill used them consistently and forced her to know where every quantity came from and what it represented, she may have had a chance of making some connections.

When watching the videos, I noticed that when Ann would pause in her explanations, Bill would frequently fill in those pauses with comments like “yeah”, “uh huh”, nodding, or other actions affirming what she was saying. I assume Bill was only doing this to show that he was listening, but it made Ann’s comments feel more like they were correct even if they were incorrect or incomplete. I think Bill having these kind of habits in conversation make it difficult for him to listen to Ann’s comments carefully and thoughtfully.
