So, here's what I think today. If you are going to teach objects at all, then you should teach them right from the beginning, or pretty much forget about it. And the objects should not remotely be abstract data types. Every effort should be made to model things that are more interesting than data (that's pretty much everything in the universe! -- so there is quite a large selection to choose from). If your OOP system shows too much mechanism for beginners, then use it to reshape itself to show beginners what they need to see: a nice combination of simplicity and power. If your object system doesn't readily allow this reshaping, then you should abandon it and find one that does (why teach something that is ultimately not sound?). BTW, this is a good way for students, especially grad students, to learn deep ideas about language and systems. They should be readily be helping to make forms of the language for the beginning classes. | 역시 스케일이커

I am astounded that folks who teach Squeak in college haven't done a lot more to make an introductory environment that gets beginners quickly into the many media objects in Squeak. This would be analogous to what we did with the etoys for children, but with more range. | apparatus, 스캣폴딩

현재 학문이 가지는 큰 문제가 현실에 도움이 되는 접근이 부족하다인데, 위와 통하는군! 학문을 오랫동안(?) '잘' 공부하면 대부분의 현실에 도움이 된다. 그런데 '잘' 공부하기 까지가 힘들다;;; 철학, 수학, 대부분의 학문이 현실 문제 해결을 하는 것이다. 문제해결이라는 같은 맥락에서 봐야지!
