I think some difficulties are finding games that will entertain the kids but are still good for observing. For example with catching and throwing it was challenging to find a way that they wouldn’t just be throwing it to win the game but to really be showing the steps in a throw including the step with the opposite foot and hip rotation. I also think it’s difficult to get the older kids to play games because they seem to just want to do what they want to do. I also think another difficult challenge is that some of the kids know that if they don’t want to do something they don’t have to. Therefore it’s harder to get them to really focus on what you want them to do. I think that when observing the catching and throwing it was hard to see the kids step as they were throwing.
