|China Town - Fong - January 30, 3009|
This week we introduced loops. When we first taught the class about programming, we told them to "program" a STOMPer to pick up something off the floor by telling them step by step what to do. This taught them the importance of giving specific instructions to the "robot". This week, we reminded them of this activity, and asked them to verbally "program" a STOMPer to eat a sandwich. We then pointed out that in order to make this "program", they had to tell the STOMPer to chew and swallow multiple times. When a series of actions must be repeated over and over, a loop can be used. We then showed them how to use loops on their computer programs. The activity for the day was to create a "remote control car" that would turn left when the touch sensor was pressed and turn right when the touch sensor was released. We left the activity open for interpretation, hoping that the kids would be able to figure out the best way to program on their own. They were then supposed to make their car maneuver through a slalom course.
We had some difficulties this week, since it was Chinese New Year. There was an assembly going on during the first two classes. Some kids decided they would rather do STOMP than finish watching the assembly, so we ended up with about half of Miss Fong's class and half of Mr. Ng's class working together. This will prove to be difficult next week, since only half of the students have learned loops. Also, many groups were able to make some sort of remote control car, but none of the groups could correctly maneuver through the slalom course. The activity wasn't really finished due to lack of time.
