While listening to Heather try to explain the phases of the moon and the seasons and watching her diagram and use 3-D models, I had a hard time pinpointing where she went off the facts until she arrived at the figure-8 orbit of the sun. I realized then that she was clearly misinformed, but I had been with her up until a point. Had I stopped listening, assuming that since she had been identified by the teacher as one of the smarter students, she was going to be the one student who breezed through the explanation?
I thought it was interesting that everyone in the class, teacher included, had stopped listening. They may have been hearing, but they weren't processing. The teacher wasn't processing that some students really didn't "see." The students weren't owning up to the fact that they still didn't completely understand. And some of the students looked like they literally couldn't see the model in the classroom - it was blocked by their classmates' heads.
I was unclear on the chronology of the video. Did the teacher go back and reteach the same concepts using the 3-D model after seeing the footage of her students? She recognized with the second video of Heather that when Heather was able to hold models of the sun, the earth, and the moon she could better explain the concepts. Did that influence the teacher to use the 3-D models herself?
Three things jumped out at me from the Khan video. First, that one student had identified that he or she was "listening but I wasn't really paying utmost attention" to the video about the juggling balls. That seems to be the crux of this problem. Good for him/her, I guess, for at least being self-aware enough to recognize his lack of attention. Secondly, I was struck by the 5 things that happened after students watched the videos - especially #3, which was "They don't recognize that what was presented differs from what they were already thinking." Which again, I think, goes back to active listening.
The third thing was that at some point during the Khan video, the narrator mentioned that students couldn't remember what they had just watched minutes earlier, even when they knew they would be interviewed. And I wondered, when the students watched the juggling balls video for the first time, did they watch it all together as a group? Did they have the ability to pause it? Could they all see it? Was there also a written transcript of the video that they could read/review during the video? The student speaking in the video that the students watched was British or Australian, perhaps (I'm not good at identifying accents). Were the students watching also of the same nationality? Did they have a hard time paying attention because of a language barrier, however slight?
These videos support, for me, a few ideas about education:
+ Students have different learning styles. The more ways the same information can be presented, the better. Using 3-D models with live teacher time with one-on-one instructor/student time with multimedia with text would probably be ideal, though probably unrealistic in terms of school budgets.
+ Personal accountability is key and it needs to be okay to say either "I don't understand" or "I was wrong." Heather realized that her figure-8 orbit was wrong, and she was able to voice that, and move forward. In the Khan video, the student who knew he wasn't paying attention was right, but he also thought that he already understood what was being said, which he didn't. Even the guys at the end of the "explain the seasons" video realized that they had said the wrong thing - that the earth takes a year, not a day, to travel around the sun.
+ Active listening is hard and distractions are everywhere. If students are given the power to control the speed of information presented, would they use it? Would it make a difference?
The usage of new media in US and global education is valid and can be powerful. I don't think it can or should replace the interaction between a live instructor and a student. Even if the live instructor begins to serve as more of a guide, directing students to different avenues for obtaining information, I think it is imperative to have someone who checks in with you, making sure that you "see."

PS - I watched the Khan video all the way through, pausing it to write down bits to remember. Then I went back and watched a portion again. And now I'm thinking about the arc of the basketball and the multiple choice answer to the question. I remember that I picked "b," but even watching the explanation video seconds later, I couldn't remember what "b" was! And I immediately was unable to recognize whether the explanation offered was suggesting that I had chosen the right answer or whether the explanation offered new information that conflicted with the choice I had made. Add to that the fact that I thought Heather's explanation of indirect rays made a lot of sense, and it has become clear to me that I need some rudimentary science review!
