I came to the class late,but did ok on the first 2 quizzes, which is a bit surprising. Overall Dr. Racket is a nice friend to play with. Sometimes I treat the tutorials like a game, a interaction with the computer.What I found fascinating is how can this crazy, random world is defined by only several numbers... Human imagination is the sky, the sky has no limits.
The difficulties emerge during the "hands-on" experiences. For some reason I kept making small, trivial mistakes which lead to an error in Dr. Racket. I could never write out my own functions without making mistakes... Sometimes it's very annoying to spend 30 minutes over one single function, just because I missed a "-" sign in between... I used multiple approaches to solve this problem. The most useful one, which requires more patience, is to check everything carefully, while comparing it with the "correct" ones from the websites. This is not a very efficient method comparing to working with a peer. Friends are always very keen to your mistakes... For no reason my S would always pin point out my mistakes. I need a little time to digest the knowledge on my own, while a little group work never hurts :).
I found binary number to be very fascinating but challenging at the same time... I was totally overwhelmed when my professor introduced this system... Everything makes no sense at all! But afterwards, I slowly understand the rules by tons of questions to S... He understands the thing pretty well, so he is like the teacher figure to me. Keeping asking "silly" questions is my only one to master the knowledge.
